Use `find_matching_capacities(...)`. Availability filters (`date_start`, `date_end`, `is_fully_available`) apply. -- `Profile_Type = "team"` (new): match the task against aggregated team profiles. Use `find_matching_teams(...)`. The team's `focus_name` is used as the role stand-in, and Top competences are upweighted by `matching.team.top_competency_weight` (default `1.5`). - -Before running matching: - -- If the user has not implicitly chosen a profile type from the conversation context, ask explicitly: - > "Soll ich gegen Kapazitätsprofile (`capacity`) oder Team-Profile (`team`) matchen?" -- Reuse the answer for follow-up turns; do not ask again. - -Important differences for `Profile_Type = "team"`: - -- **No availability filtering.** `availability_date_start`, `availability_date_end`, and `is_fully_available` are accepted but ignored. Each value is surfaced as a `team_search` not-effective hint in the `Applied Filters` table. Do not ask the user for a time range when the chosen profile type is `team`. -- **Result columns differ.** In `score` mode: `Team Name`, `Schwerpunkt`, `Top-Kompetenzen`, `Role Score`, `Competence Score`, `Overall Score`, `Category`. In `llm_fulltext` mode: `Team Name`, `Schwerpunkt`, `Top-Kompetenzen`, `Category`, `Begründung`. -- **Search session marker.** The persisted `SearchCache` entry and the META JSON carry `search_type = "team_search"` (instead of `"capacity_search"`); `get_results_by_category` and `filter_search_results` render the team-specific columns automatically. -- **Filter behavior.** `role_filter` matches against `team.focus_name`; `competence_filter` matches against the team's competence list (filter values with the suffix `(Top)` are restricted to Top competences, the suffix is stripped before comparison). - -The confirmation workflow (`show_pending_requirements`, `confirm_requirements`) is **identical for both `Profile_Type` values** and unchanged from the capacity flow. - -## Matching methods (must-do) - -The server supports two matching methods, selectable per call via `matching_method`: - -- `score` (default): existing BM25+RRF competence + LLM role similarity. Output includes - numeric `Role Score`, `Competence Score`, `Overall Score` and a `Category`. -- `llm_fulltext`: LLM-based full-text comparison of complete profiles. **No numeric scores.** - Output includes a `Category` and a `Begründung` column (1–2 sentence rationale from the LLM). - -Before calling `find_matching_capacities(...)`, `find_matching_tasks(...)`, or `find_matching_teams(...)`: - -- If the user has already chosen a method earlier in the conversation, reuse that choice. -- Otherwise ask the user explicitly, e.g.: - > "Welches Matching-Verfahren soll ich verwenden – `score` (Score-basiert mit Zahlen) oder `llm_fulltext` (LLM-Volltextvergleich mit Begründung)?" -- Pass the chosen value as the `matching_method` parameter to the tool call. -- Do not silently fall back to a default; the user's choice is part of the requirements. - -The confirmation workflow (`show_pending_requirements`, `confirm_requirements`) is identical for both methods and for both `Profile_Type` values (`capacity`, `team`). Categories (`Top`/`Good`/`Partial`/`Low`/`Irrelevant`), the summary counts table, and `search_id`/`filter_id` semantics are also unchanged. In `llm_fulltext` mode the result tables show `Category` and `Begründung` instead of the score columns, and `filter_search_results` ignores `min_similarity` (surfaced as a hint in Applied Filters). - -### Confirmation gating semantics (important) - -- The server's confirmation state is stored in in-memory session state. -- This state is **not** safe as a multi-client / multi-tenant source of truth. -- Therefore, treat confirmation gating primarily as a **client-side UX rule**: - you (the agent) must only execute matching after an explicit user Yes/No. - -### Confirmation workflow (must-do, strict) - -Never auto-confirm. - -- If `matching.require_confirmation = true`: - 1. After requirements have been captured/updated (including guided capture), call `show_pending_requirements()` to display the review table. - 2. You MUST ask the user explicitly: "Soll ich diese Anforderungen so übernehmen und die Suche starten?" (Ja/Nein). - 3. Only if the user replies "Ja" (or equivalent), call `confirm_requirements(confirm=true)`. - - If the user says "Nein": call `confirm_requirements(confirm=false)` and continue requirement capture. - -- If `matching.require_confirmation = false`: - - Do **not** ask for confirmation. - - Do **not** call `show_pending_requirements()` / `confirm_requirements()`. - - Proceed directly to matching once requirements are complete. - -Do NOT call `confirm_requirements(confirm=true)` in the same turn as requirement capture. - -If you are unsure whether confirmation is enabled, prefer to **assume it is enabled** and ask for confirmation (safer UX) *unless* the user explicitly asks to skip confirmation. - -### How to decide between `extract_requirements(...)` and guided capture - -Use `extract_requirements(task_description, ...)` only when the user provides a reasonably complete description. - -Use **guided capture** when: -- the user is doing an ad-hoc search (no DB task), AND -- the description is vague/too short, or key fields are missing. - -Rule of thumb: -- If you would still need to ask **more than one** follow-up question, start guided capture. - -### Ad-hoc searches with incomplete descriptions (must-do) - -If the user is looking for a capacity **not based on an existing DB task** and does **not** provide a complete task description (e.g. only a role, only a few skills, or a very short/vague sentence), you MUST start **guided capture**. - -- Trigger condition (ad-hoc + incomplete description): - - no `task_id` / not a DB-task workflow, AND - - the user did not provide a sufficiently detailed task description. - -**Definition (operational):** treat the description as *incomplete* unless it contains at least: - -- a short **scope/goal** (what will be built/done), AND -- at least **2 concrete competences/technologies** (or one competence + clear domain), AND -- at least a rough **time range** (start/end or open-ended) - -If these are not present, do not call `extract_requirements(...)`.

Es wird dabei die asynchrone Parallelisierung (concurrent requests) genutzt, nicht die Azure Batch API (die für Offline-Verarbeitung gedacht ist und keine Echtzeit-Antworten liefert). - -## Glossar - -- **LLM_Fulltext_Matcher**: Bestehendes Modul (`matching/llm_fulltext_matcher.py`), das den LLM-basierten Volltext-Vergleich durchführt und Kategorien direkt zuweist. -- **AzureOpenAIClient**: Wrapper für Azure-OpenAI-Chat-Completions in `azure/openai_client.py`. -- **Batch**: Eine Gruppe von LLM-Anfragen, die gleichzeitig (concurrent) an die Azure OpenAI API gesendet werden. -- **Batch_Size**: Maximale Anzahl gleichzeitig laufender LLM-Anfragen innerhalb eines Batches. -- **Concurrency_Limit**: Obergrenze für die Anzahl paralleler HTTP-Anfragen an die Azure OpenAI API, um Rate-Limits nicht zu überschreiten. -- **Rate_Limit**: Von Azure OpenAI auferlegte Begrenzung der Anfragen pro Zeiteinheit (Requests per Minute / Tokens per Minute). -- **Semaphore**: Synchronisationsmechanismus zur Begrenzung der gleichzeitigen Zugriffe auf eine Ressource. -- **MCP_Server**: Der Teamlandkarte MCP-Server (`mcp_server.py`). -- **Capacity**: Frozen Dataclass `Capacity` in `models.py`. -- **Task**: Frozen Dataclass `Task` in `models.py`. -- **Capacity_Profile**: Aggregiertes Volltext-Profil einer Kapazität. -- **Task_Profile**: Aggregiertes Volltext-Profil einer Aufgabe. - -## Anforderungen - -### Anforderung 1: Parallele LLM-Aufrufe mit konfigurierbarer Concurrency - -**User Story:** Als Nutzer möchte ich, dass das LLM-Volltext-Matching mehrere Kapazitäten bzw. Aufgaben gleichzeitig bewertet, damit die Gesamtwartezeit bei vielen Kandidaten deutlich sinkt. - -#### Akzeptanzkriterien - -1. WHEN `match_capacities` oder `match_tasks` mit einer Liste von Kandidaten aufgerufen wird, THE LLM_Fulltext_Matcher SHALL alle LLM-Aufrufe für die Kandidaten concurrent (nicht sequenziell) ausführen, begrenzt durch das konfigurierte Concurrency_Limit. -2. THE LLM_Fulltext_Matcher SHALL ein Concurrency_Limit verwenden, das die maximale Anzahl gleichzeitig laufender LLM-Anfragen auf einen konfigurierbaren Wert begrenzt. -3. THE LLM_Fulltext_Matcher SHALL als Standard-Concurrency_Limit den Wert 5 verwenden, wenn kein anderer Wert konfiguriert ist. -4. WHEN das Concurrency_Limit erreicht ist, THE LLM_Fulltext_Matcher SHALL weitere LLM-Anfragen zurückhalten, bis ein laufender Aufruf abgeschlossen ist, ohne Anfragen zu verwerfen. -5. THE LLM_Fulltext_Matcher SHALL die Concurrency-Begrenzung über einen asyncio-Semaphore implementieren, sodass die Event-Loop nicht blockiert wird. - -### Anforderung 2: Konfiguration des Concurrency-Limits - -**User Story:** Als Entwickler möchte ich das Concurrency-Limit über die Konfigurationsdatei anpassen können, damit ich es an die Rate-Limits meines Azure-OpenAI-Deployments anpassen kann. - -#### Akzeptanzkriterien - -1. THE MCP_Server SHALL in `config.toml` unter `[azure_openai]` einen optionalen Schlüssel `max_concurrency` akzeptieren, der das Concurrency_Limit für parallele LLM-Aufrufe festlegt. -2. WHEN `azure_openai.max_concurrency` nicht in `config.toml` gesetzt ist, THE MCP_Server SHALL den Standardwert 5 verwenden. -3. IF `azure_openai.max_concurrency` auf einen Wert kleiner als 1 gesetzt ist, THEN THE MCP_Server SHALL beim Start einen `ConfigError` mit beschreibender Meldung werfen. -4. IF `azure_openai.max_concurrency` auf einen Wert größer als 20 gesetzt ist, THEN THE MCP_Server SHALL beim Start einen `ConfigError` mit beschreibender Meldung werfen, da ein zu hoher Wert Rate-Limit-Fehler provoziert. -5. THE AzureOpenAIConfig SHALL ein Feld `max_concurrency` vom Typ `int` mit Standardwert 5 enthalten. - -### Anforderung 3: Ergebniskonsistenz bei paralleler Verarbeitung - -**User Story:** Als Nutzer möchte ich, dass die Ergebnisse des parallelen Matchings identisch zu denen des sequenziellen Matchings sind, damit die Umstellung auf Batching keine funktionalen Unterschiede verursacht. - -#### Akzeptanzkriterien - -1. THE LLM_Fulltext_Matcher SHALL nach Abschluss aller parallelen LLM-Aufrufe die Ergebnisse in derselben deterministischen Sortierreihenfolge liefern wie bisher (primär nach Kategorie, sekundär nach `item_id` aufsteigend). -2. THE LLM_Fulltext_Matcher SHALL bei paralleler Verarbeitung dieselbe Fehlerbehandlung anwenden wie bei sequenzieller Verarbeitung: fehlgeschlagene Aufrufe erscheinen in der Fehlerliste, erfolgreiche in `by_category`. -3. THE LLM_Fulltext_Matcher SHALL sicherstellen, dass die Reihenfolge der Eingabe-Kandidaten keinen Einfluss auf die Sortierung der Ausgabe hat. -4. THE LLM_Fulltext_Matcher SHALL bei paralleler Verarbeitung keine Race-Conditions bei der Zuordnung von LLM-Antworten zu Kandidaten aufweisen; jede Antwort wird exakt dem zugehörigen Kandidaten zugeordnet. - -### Anforderung 4: Fehlerbehandlung bei Rate-Limit-Überschreitung - -**User Story:** Als Entwickler möchte ich, dass das System bei Rate-Limit-Fehlern der Azure OpenAI API robust reagiert, damit einzelne 429-Fehler nicht den gesamten Matching-Lauf abbrechen. - -#### Akzeptanzkriterien - -1. WHEN ein LLM-Aufruf innerhalb eines Batches mit einem HTTP-429-Fehler (Rate Limit Exceeded) fehlschlägt, THE AzureOpenAIClient SHALL den Aufruf nach einer exponentiellen Backoff-Pause erneut versuchen (bestehendes Retry-Verhalten). -2. WHEN ein LLM-Aufruf nach Ausschöpfung aller Retries endgültig fehlschlägt, THE LLM_Fulltext_Matcher SHALL diesen Kandidaten in der Fehlerliste ausweisen, ohne die parallele Verarbeitung der übrigen Kandidaten zu beeinflussen. -3. THE LLM_Fulltext_Matcher SHALL sicherstellen, dass ein Fehler bei einem einzelnen Kandidaten nicht zum Abbruch oder zur Verzögerung der Verarbeitung anderer Kandidaten führt. -4. IF alle LLM-Aufrufe eines Batches fehlschlagen, THEN THE LLM_Fulltext_Matcher SHALL ein Ergebnis mit leeren Kategorien und einer vollständigen Fehlerliste zurückgeben, ohne eine Exception zu werfen. - -### Anforderung 5: Beibehaltung der bestehenden Schnittstelle - -**User Story:** Als Entwickler möchte ich, dass die öffentliche Schnittstelle des LLM_Fulltext_Matcher unverändert bleibt, damit bestehende Aufrufer (MCP_Server, Tests) ohne Anpassung weiterhin funktionieren. - -#### Akzeptanzkriterien - -1. THE LLM_Fulltext_Matcher SHALL die Signaturen von `match_capacities` und `match_tasks` unverändert beibehalten (gleiche Parameter, gleicher Rückgabetyp `LlmFulltextResult`). -2. THE LLM_Fulltext_Matcher SHALL den Rückgabetyp `LlmFulltextResult` (mit `by_category` und `errors`) unverändert beibehalten. -3. WHEN der LLM_Fulltext_Matcher mit einer leeren Kandidatenliste aufgerufen wird, THE LLM_Fulltext_Matcher SHALL sofort ein leeres Ergebnis zurückgeben, ohne LLM-Aufrufe zu starten. -4. THE LLM_Fulltext_Matcher SHALL das neue `max_concurrency`-Feld als optionalen Konstruktor-Parameter akzeptieren, mit Standardwert 5. - -### Anforderung 6: Logging und Beobachtbarkeit - -**User Story:** Als Entwickler möchte ich nachvollziehen können, wie viele LLM-Aufrufe parallel laufen und wie lange das Batching insgesamt dauert, damit ich Performance-Probleme diagnostizieren kann. - -#### Akzeptanzkriterien - -1. WHEN ein Batch-Matching gestartet wird, THE LLM_Fulltext_Matcher SHALL eine Log-Nachricht auf Level INFO ausgeben, die die Anzahl der Kandidaten und das konfigurierte Concurrency_Limit enthält. -2. WHEN ein Batch-Matching abgeschlossen ist, THE LLM_Fulltext_Matcher SHALL eine Log-Nachricht auf Level INFO ausgeben, die die Gesamtdauer, die Anzahl erfolgreicher Kategorisierungen und die Anzahl der Fehler enthält. -3. WHEN ein einzelner LLM-Aufruf innerhalb des Batches fehlschlägt, THE LLM_Fulltext_Matcher SHALL eine Log-Nachricht auf Level WARNING ausgeben, die die `item_id` und den Fehlergrund enthält. - -### Anforderung 7: Abwärtskompatibilität mit Score-Modus - -**User Story:** Als Nutzer möchte ich, dass das Batching ausschließlich den LLM-Volltext-Modus betrifft und der Score-Modus unverändert bleibt. - -#### Akzeptanzkriterien - -1. WHEN `matching_method = "score"` verwendet wird, THE MCP_Server SHALL das bestehende Score-basierte Matching ohne Änderungen ausführen. -2. THE LLM_Fulltext_Matcher SHALL ausschließlich für den Modus `llm_fulltext` verwendet werden; der Score-Modus nutzt weiterhin den bestehenden `Matcher` und `SimilarityEngine`. -3. THE MCP_Server SHALL keine neuen Abhängigkeiten oder Konfigurationsparameter einführen, die den Score-Modus beeinflussen. diff --git a/bahn/teamlandkarte-mcp/.kiro/specs/llm-batch-matching/tasks.md b/bahn/teamlandkarte-mcp/.kiro/specs/llm-batch-matching/tasks.md deleted file mode 100644 index 458cb05..0000000 --- a/bahn/teamlandkarte-mcp/.kiro/specs/llm-batch-matching/tasks.md +++ /dev/null @@ -1,100 +0,0 @@ -# Implementierungsplan: LLM Batch-Matching (Concurrent Requests) - -## Übersicht - -Sequenzielle LLM-Aufrufe in `LlmFulltextMatcher` werden durch `asyncio.gather()` mit Semaphore-Begrenzung ersetzt.

Anschließend wird auf `[0, 1]` - geclampt: - ```python - weighted = min(1.0, s * (top_weight if best_match in top_set else 1.0)) - ``` - Die Mittelung über die Required-Kompetenzen ergibt die `competence_score`. -4. **Role Score** über `SimilarityEngine.compute_role_similarity( - requirements.role_name, team.focus_name)` (Anforderung 6.3).

IF kein Team mit der angegebenen Team_Id existiert, THEN THE MCP_Server SHALL eine Fehlermeldung zurückgeben, die die ungültige Team_Id nennt. -4. THE MCP_Server SHALL die Listen `Kompetenzen` und `Referenzen` in der gleichen deterministischen Reihenfolge ausgeben, die der DBClient liefert (siehe Anforderungen 3.7 und 4.7). - - -### Anforderung 10: Anpassung der Agenten-Konfigurationen - -**User Story:** Als Nutzer möchte ich, dass sowohl der GitHub-Copilot-Agent `teamlandkarte_agent` als auch der Kiro-Pendant-Agent das neue Matching gegen Team-Profile kennen und mich aktiv nach der gewünschten Profilart fragen, damit das neue Feature über die Agenten nutzbar ist. - -#### Akzeptanzkriterien - -1. THE Teamlandkarte_Agent SHALL in seiner Konfigurationsdatei (`.github/agents/teamlandkarte_agent.md`) und im Pendant `.kiro/agents/teamlandkarte.md` die Existenz und den Zweck der beiden Profile_Type-Werte `capacity` und `team` dokumentieren. -2. WHEN der Nutzer eine Suche nach passenden Profilen für eine Aufgabe startet, THE Teamlandkarte_Agent SHALL den Nutzer explizit nach dem gewünschten Profile_Type (`capacity` oder `team`) fragen, sofern dieser nicht bereits aus dem Verlauf hervorgeht. -3. THE Teamlandkarte_Agent SHALL die Skills/Workflows so erweitern, dass `find_matching_teams` als alternatives Such-Tool zu `find_matching_capacities` verfügbar ist und mit dem Parameter `matching_method` aufgerufen wird. -4. THE Teamlandkarte_Agent SHALL den Nutzer darauf hinweisen, dass bei einer Team-Suche keine Verfügbarkeitsfilter wirksam sind und die Ergebnisspalten von einer Kapazitäts-Suche abweichen. -5. THE Teamlandkarte_Agent SHALL den bestehenden Bestätigungs-Workflow (`show_pending_requirements`, `confirm_requirements`) beibehalten und für beide Profile_Type-Werte gleich anwenden. -6.

Availability filters apply. | -| `team` (new) | `find_matching_teams(...)` | The task is matched against aggregated team profiles (`Team_Name`, `Schwerpunkt`, `Über uns`, `Leistungen`, `Interessen`, Top/Non-Top competences, references). Availability filters do **not** apply. | - -The persisted search session is tagged accordingly: - -- Capacity searches: `search_type = "capacity_search"` in `SearchCache` and the META JSON. -- Team searches: `search_type = "team_search"` in `SearchCache` and the META JSON. - -`find_matching_teams` accepts the same `matching_method` parameter (`score` | `llm_fulltext`) as `find_matching_capacities`. In `score` mode the team's `focus_name` is used as the role stand-in, and Top competences are upweighted by the configurable factor `matching.team.top_competency_weight` (default `1.5`, must be numeric and `>= 1.0`). - -Result columns differ between the two profile types: - -| Mode | Columns (capacity) | Columns (team) | -|------|--------------------|----------------| -| `score` | `Owner`, `Role`, `Competences`, `Availability`, `Role Score`, `Competence Score`, `Overall Score`, `Category` | `Team Name`, `Schwerpunkt`, `Top-Kompetenzen`, `Role Score`, `Competence Score`, `Overall Score`, `Category` | -| `llm_fulltext` | `Owner`, `Role`, `Competences`, `Availability`, `Category`, `Begründung` | `Team Name`, `Schwerpunkt`, `Top-Kompetenzen`, `Category`, `Begründung` | - -Filter behavior on a `team_search` cache entry: - -- `role_filter` matches against `team.focus_name` (Schwerpunkt). -- `competence_filter` matches against the team's competence list. Filter values with the suffix `(Top)` are restricted to Top competences (the suffix is stripped before comparison). -- `availability_date_start`, `availability_date_end`, and `is_fully_available` are accepted but **ignored**. Each value is surfaced in the `Applied Filters` table with a `team_search` not-effective hint. - -### Matching Methods - -The server supports **two matching methods** that callers select per call via the `matching_method` parameter on `find_matching_capacities`, `find_matching_tasks`, and `find_matching_teams`: - -| Value | Description | Output columns | -|-------|-------------|----------------| -| `score` (default) | BM25+RRF competence similarity + LLM role similarity. Existing behavior. | `Role Score`, `Competence Score`, `Overall Score`, `Category` | -| `llm_fulltext` | LLM-based full-text comparison of complete profiles via Azure OpenAI Chat Completion. One call per candidate, returns `{category, rationale}`. | `Category`, `Begründung` (rationale, 1–2 sentences). **No numeric scores.** | - -When `matching_method` is omitted, the server uses the configured default: - -```toml -[matching] -# Default method for new searches when callers omit matching_method. -# Allowed: "score" | "llm_fulltext" -default_method = "score" -``` - -Both methods share the same prefilters (e.g. availability), the same `search_id`/`filter_id` flow, and the same Markdown summary table. Differences: - -- In `llm_fulltext` mode the result tables use a `Begründung` column instead of the score columns. The persisted META JSON contains `"matching_method": "llm_fulltext"` so `get_results_by_category` and `filter_search_results` render the correct schema automatically. -- In `llm_fulltext` mode `filter_search_results` ignores `min_similarity` (it is not applicable without numeric scores). It is surfaced in the Applied Filters table as a hint. - -#### Additional database views in `llm_fulltext` mode - -In addition to the views used by the `score` method, `llm_fulltext` reads: - -- `teamlandkarte_v_capacities_latest.description` -- `teamlandkarte_v_capacity_certificates_latest` (joined on `capacity_id`) -- `teamlandkarte_v_capacity_references_latest` (joined on `capacity_id`) -- `teamlandkarte_v_partners_latest` — joined to references via a **LEFT JOIN** `teamlandkarte_v_capacity_references_latest.partner_id = teamlandkarte_v_partners_latest.id`. The partner `name` column is exposed as `partner_name` and surfaces inside the LLM-visible profile. When `partner_id` is `NULL` or no partner matches, `partner_name` is the empty string and the reference is still kept (only the `Partner:` token is omitted in the serialized profile). - -The partner LEFT JOIN is part of the same SQL query that loads references; no extra round-trip is needed. - -#### Example output (LLM mode) - -A capacity-search result table in `llm_fulltext` mode looks roughly like this: - -```markdown -## Summary -| Category | Count | -| --- | --- | -| Top | 1 | -| Good | 2 | -| Partial | 0 | -| Low | 0 | -| Irrelevant | 1 | - -## Top -| ID | Owner | Role | Competences | Availability | Category | Begründung | -| --- | --- | --- | --- | --- | --- | --- | -| 12345 | Erika Musterfrau | Senior Backend Developer | Python, FastAPI, PostgreSQL | 100% | Top | Profil deckt Python/FastAPI vollständig ab und enthält Referenzprojekte mit identischem Tech-Stack. | -``` - -A typical META line emitted by the matching tools (and echoed by `get_results_by_category` / `filter_search_results`): - -```text -META={"search_id":"7c0e6f50-...","filter_id":null,"default_category":"Top","matching_method":"llm_fulltext"} -``` - -In `score` mode the same META line carries `"matching_method":"score"` and the result table keeps the existing `Role Score | Competence Score | Overall Score | Category` columns. - -#### Mini walkthrough (LLM mode) - -A typical agent-driven flow when the user asks for an LLM-based capacity search: - -1. Capture and confirm requirements as usual (`collect_structured_requirement_data`, `show_pending_requirements`, `confirm_requirements(confirm=true)`). -2. Ask the user once: *"Welches Verfahren soll ich verwenden – `score` oder `llm_fulltext`?"* -3.

The tool returns the `Summary` counts + the first non-empty category table (with the `Begründung` column) and emits a META line containing `"matching_method":"llm_fulltext"`. -5. Page through other categories with `get_results_by_category(search_id=..., category="Good", ...)`. Because the persisted payload carries `matching_method`, the table is rendered automatically with `Begründung` instead of score columns. -6.

Run `find_matching_teams(role_name, competences, matching_method?)`: - - Resolve `matching_method` (parameter > `[matching].default_method` > `"score"`); reject unknown values with an error listing the allowed values, without any DB or LLM call - - Validate minimum requirements (`competences` non-empty) - - Load all teams from the DB-backed cache `_get_teams_cached()`. The DB layer joins `teamlandkarte_v_teams_latest` with `teamlandkarte_v_teammeter_organizational_units_latest` (INNER JOIN over `team_id = id` for the team name), and aggregates competences (`teamlandkarte_v_teammeter_team_competences_latest` joined to `teamlandkarte_v_competences_latest` over `competence_id = id`) and references (`teamlandkarte_v_team_references_latest` LEFT JOIN `teamlandkarte_v_partners_latest` over `partner_id = id`, exposing `name` as `Partner_Name`). Joins between team master data, competences, and references run over `ouid`. - - **No availability prefilter**: team profiles do not carry an availability range; any provided date range is ignored and surfaced as a not-effective hint in the `Applied Filters` table. - - Branch by `matching_method`: - - `"score"`: build the requirements competence list, derive each team's competence list and parallel top-competence set from `Team.competences`, and compute competence similarity via the existing `SimilarityEngine`. Top competences are upweighted by `matching.team.top_competency_weight` (default `1.5`); the per-required score is clamped to `[0, 1]`. Role similarity uses `Team.focus_name` as the role stand-in (`compute_role_similarity(req.role_name, team.focus_name)`). Overall score and category use the same `compute_overall(...)` / `categorize(...)` thresholds as for capacities. - - `"llm_fulltext"`: build a `TaskProfile` from the requirements and a `TeamProfile` per team via `build_team_profile` + `serialize_team_profile`. The user prompt is `=== Aufgabe ===` + `=== Team ===` (with an `ID:` header). The system prompt and JSON schema (`{"category": ..., "rationale": ...}`) are reused from the capacity LLM path; invalid categories are normalized to `Irrelevant` with a hint suffix in the rationale; LLM/JSON errors land in a separate `errors` list. - - Store results in `SearchCache` with `search_type = "team_search"` and `matching_method = ...` -> return `search_id`. The META JSON exposes both `search_type` and `matching_method` so `get_results_by_category` / `filter_search_results` render the team-specific columns. -4. Browse/filter results: - - `get_results_by_category(search_id, category, page, page_size)` (renders `Begründung` column in `llm_fulltext` mode) - - `filter_search_results(search_id, ...)`. `role_filter` matches against `Team_Focus_Name`; `competence_filter` matches the competence names of the team and supports a `(Top)` suffix that restricts the filter to top competences. `availability_date_start`, `availability_date_end`, and `is_fully_available` are ignored for `team_search` and surfaced as `team_search` not-effective hints in the `Applied Filters` table. - -### 6.5 Role inference flow - -1. `infer_primary_role(task_id=... | task_text=...)` -2. Fetch all role names from DB vocabulary view -3. Send task text + role list to LLM (JSON response format) -4. Validate returned role exists in DB vocabulary -5.

Support for **true Azure Embeddings batch requests** (single request with multiple inputs), including chunking, while preserving deterministic error semantics. - -## Motivation - -The current implementation calls embeddings repeatedly inside inner loops. While a persistent SQLite cache exists, repeated calls still incur overhead: - -- many redundant `cache.get(...)` reads -- repeated normalization/keying for identical strings -- unnecessary Azure round-trips when multiple missing terms are encountered and requests are performed sequentially - -The result is that `find_matching_capacities(...)` can be slow, and while the second run is faster (due to cache hits), it can still take noticeable time. - -## Goals - -1.

For large candidate lists, this forces a high number of calls to `_embed`, and repeated SQLite reads. - -#### New behavior - -Add a prefetch step that: - -- collects all texts required to compute similarity for a run (competences **and roles**) - - **Important:** this collection is performed **across the entire candidate set** (i.e., roles and competences of **all free capacities at once**), not person-by-person. -- normalizes for cache key stability -- deduplicates texts -- fetches all embeddings from caches/API in bulk -- returns a mapping from normalized text → embedding vector - -Then similarity computation uses the prefetched mapping (pure Python vector math). - -### 2) Per-run in-memory cache - -Add a lightweight in-memory dict for the duration of a single matching invocation. - -- key: `(model, dimensions, normalized_text)` or reuse the computed SHA256 cache key -- value: `list[float]` - -This prevents repeated SQLite lookups for frequently used items (common competences, repeated role strings, etc.). - -### 3) True Azure embeddings batch calls - -Change `AzureOpenAIClient.get_embeddings_batch(...)` to use the Azure embeddings API with `input=[...]` to embed multiple texts in a single request. - -Key details: - -- supports chunking with a **configurable** batch size -- preserves stable output ordering and deterministic error semantics -- continues to log costs via `CostTracker` - -If any item fails, the batch call should raise `AzureAPIError` (no fallback). - -## Decisions (resolved) - -- **Scope**: bulk prefetch includes **competences and roles**. -- **Batching**: Azure embeddings requests are made in chunks with a **configurable** batch size. -- **Normalization**: keep the current text normalization and cache-key behavior. -- **Concurrency**: process chunks **sequentially** (no parallel calls). -- **In-memory cache lifecycle**: implemented as a new instance variable in `SimilarityEngine` and **not** created/cleaned per matching invocation. -- **Prefetch API**: new public method `prefetch_embeddings(required_texts, candidate_texts, required_roles, candidate_roles)` that returns a mapping from normalized text → embedding vector. -- **Azure batch response ordering**: rely on the `index` field in the response if available, otherwise assume stable ordering. -- **Error handling**: entire matching operation fails immediately; attempt to identify and report which specific text(s) caused the failure. -- **Cost tracking**: log once per batch chunk with a count. -- **Empty inputs**: -

-## Task Breakdown - -### Phase 1: Design & Validation Plan - -- [x] 1.1 Identify hot paths during matching (where `_embed(...)` is called most). -- [x] 1.2 Confirm normalization + cache key rules are unchanged and documented. -- [x] 1.3 Define expected call-count behavior (upper bounds): - - per run: max 1 Azure embedding per unique normalized text (subject to chunking, after cache resolution) - - per run: max 1 SQLite read per unique normalized text (after in-memory cache check) - -### Phase 2: Global Bulk Prefetch in `SimilarityEngine` -

-## Context - -This design specifies the internal architecture for the BM25 + Reciprocal Rank Fusion -(RRF) competence matching strategy with optional LLM-based Auto-Tagging, controlled by -`matching.similarity.use_bm25_search` and `matching.similarity.use_auto_tagging`. - -The goal is to provide a lexical alternative to embedding-based similarity that assigns -near-zero scores when candidate competences do not literally overlap with the required -competences, while still producing a normalized score compatible with the existing -`Matcher` and `scorer` contracts. - -Auto-Tagging optionally extends BM25 by having an LLM pre-expand each candidate's -competence list with canonical forms of any required competences it already covers -(synonyms, abbreviations, cross-language equivalents). This bridges the lexical gap for -known skill aliases without persisting any data. - ---- - -## Key Decisions - -### 1. BM25 is per-skill only, not aggregate - -**Decision:** `_bm25_rrf_similarity()` operates per required competence (like the existing -`per_skill` strategy), not as an aggregate over all required competences. - -**Rationale:** -- Aggregate-style BM25 would require concatenating all required competences into a single - query document, which loses the per-skill granularity needed for `matched_competences` - and `missing_competences` diagnostic output. -- Per-skill BM25 + RRF preserves the same output shape as `_per_skill_similarity()`, - making it a drop-in replacement. - ---- - -### 2. BM25 index is built once globally over all filtered candidates - -**Decision:** One `Bm25Index` is built over the **union of all filtered candidates' -competences** before the per-candidate scoring loop in `Matcher.match()`, not fresh per -`compute_competence_similarity()` call. The index is passed in as `global_index` and each -per-candidate call filters BM25 results down to that candidate's own competence set. - -**Rationale:** -- **IDF pathology fix:** With a per-person corpus (N = that person's competence count), - BM25 IDF is `log((N − df + 0.5) / (df + 0.5))`. For N = 5–30 and any term that appears - in most or all documents, this is 0 or negative. `rank_bm25` therefore returns zero or - negative raw scores for typical real-world skill lists — making every BM25 match appear - as zero before `max(0.0, raw)` clamping. A global corpus of all candidates' competences - ensures N is large enough for IDF to carry meaningful signal. -- **Still cheap:** Building one index over the deduplicated union of all candidates' - competences is O(M) where M is the total unique competence count — still milliseconds. -- **Correctness over caching:** The global index is not cached across MCP tool calls; it is - rebuilt fresh for each `match_candidates` invocation, so stale state is impossible. - ---- - -### 3. RRF with single ranked list (BM25 only) - -**Decision:** For the initial implementation, `reciprocal_rank_fusion()` fuses a single -ranked list (BM25 ranks only), effectively normalizing BM25 scores via the RRF formula. - -**Formula (single list):** - -``` -rrf_score(candidate) = 1 / (k + rank(candidate)) -``` - -where `k = 60` (standard constant, Cormack et al. 2009), and `rank` is 1-based. - -**Output normalization:** -The raw RRF scores sum to a value > 1 across all candidates. To map to [0.0, 1.0]: - -``` -normalized = rrf_score(best_candidate) / rrf_score_at_rank_1 - = 1 / (k + rank) * (k + 1) - = (k + 1) / (k + rank) -``` - -For `k=60`, rank 1 → 1.0, rank 2 → 61/62 ≈ 0.984, rank 10 → 61/70 ≈ 0.871. - -This means BM25 scores do NOT inherently drop to near-zero for adjacent candidates. -To address this, RRF scores are **zeroed** if the underlying BM25 score is 0.0, because -a BM25 score of 0 means **no token overlap at all**. This is the critical property that -fixes the false-positive problem. - -**Implementation:** -```python -def reciprocal_rank_fusion( - ranked_lists: list[list[tuple[str, float]]], - *, - k: int = 60, -) -> dict[str, float]: - ... - # Skip lists with no BM25 signal at all - if all(score == 0.0 for _, score in ranked_list): - continue - - # IMPORTANT: Keep (candidate, 0.0) entries in the ranked list for transparency, - # but treat them as "no signal" for fusion. I.e., candidates with BM25==0.0 MUST - # NOT receive a positive fused score just because they have a (low) rank at the - # end of the list. - for rank, (candidate, score) in enumerate(ranked_list, start=1): - if score == 0.0: - continue - fused[candidate] += 1 / (k + rank) - ... -``` - ---- - -### 4. `best_match` reported per required competence - -**Decision:** `best_match` in the output dict is the candidate with the highest BM25 score -(rank 1 in the BM25 list). If no candidate has any token overlap (BM25 = 0 for all), -`best_match = None` and `score = 0.0`. - ---- - -### 5. Role similarity unchanged - -**Decision:** `compute_role_similarity()` is always embedding-based, regardless of -`use_bm25_search`. - -**Rationale:** -- Role names are short, single-phrase labels ("Backend Developer", "Data Engineer"). -- Embeddings handle multilingual and synonym variants better for roles. -- BM25's exact-match strength is less valuable for role inference. - ---- - -### 6. `rank_bm25` as the BM25 library - -**Decision:** Use the `rank-bm25` PyPI package (`BM25Okapi` class). - -**Rationale:** -- Pure Python, no C extensions or native code. -- Actively maintained, MIT licensed. -- Implements BM25 Okapi (the standard variant) with configurable `k1` and `b` parameters. -- Minimal footprint, no additional build steps. - -**Tokenization:** -Candidate and query texts are tokenized by lowercasing and splitting on non-word -characters (whitespace, hyphens, slashes, parentheses, dots): - -```python -import re - -def _tokenize(text: str) -> list[str]: - return [t for t in re.split(r"[\W_]+", text.lower()) if t] -``` - -This ensures "Progressive Web App (PWA)" tokenizes to -`["progressive", "web", "app", "pwa"]`, and "CI/CD Pipeline" becomes -`["ci", "cd", "pipeline"]`. - ---- - -### 7. No changes to `Matcher`, `scorer`, or output format - -**Decision:** `_bm25_rrf_similarity()` returns `dict[str, dict[str, object]]` in the -identical shape to `_per_skill_similarity()`: - -```python -{ - "Python": { - "score": 0.0, - "best_match": None, - "rationale": "BM25: no token overlap with any candidate competence.", - }, - "Machine Learning": { - "score": 0.0, - "best_match": None, - "rationale": "BM25: no token overlap with any candidate competence.", - }, -} -``` - -The `Matcher.match()` loop, the `ScoredCapacity` model, the `compute_overall()` scorer, -and all MCP tool output formatting remain unchanged. - ---- - -### 8. LLM Auto-Tagging: ephemeral competence expansion - -**Decision:** When `use_auto_tagging = true`, the `AutoTagger` issues a single LLM -chat-completion call per candidate per scoring invocation to identify which required -competences are already covered by the candidate's existing competences (via synonym, -abbreviation, or cross-language equivalence). The response is a JSON list of canonical -required-competence names to add to the candidate's working list. The expanded list is -used only for that BM25 scoring call and is **never persisted**. - -**Rationale:** -- Auto-tagging directly addresses BM25's known limitation with lexical disjoint synonyms - (e.g., "ML" for "Machine Learning", "Softwarearchitektur" for "Software Architecture"). -- Making the expansion ephemeral keeps the data model clean and audit-friendly. -- Restricting additions to "names already covered by the candidate's existing entries" - means the LLM cannot invent skills — it can only surface canonical equivalents. -- LLM call cost is bounded: one call per candidate per `compute_competence_similarity()` - invocation, with a compact prompt (required list + candidate list). - -**LLM prompt schema:** -``` -System: You are a skill-taxonomy assistant. Given a list of REQUIRED competences and a - candidate's EXISTING competences, output ONLY the canonical names from REQUIRED - that are already covered by one or more entries in EXISTING (via synonym, - abbreviation, or cross-language equivalence). Do not invent new skills. - -User: REQUIRED: ["Machine Learning", "Python", "CI/CD"] - EXISTING: ["ML", "Python", "Jenkins", "Continuous Integration"] - -Response (JSON): {"additions": ["Machine Learning", "CI/CD"]} -``` - -**Azure OpenAI `response_format`:** `{"type": "json_object"}` is used to enforce -structured JSON output, eliminating parsing failures. - -**Error handling:** If the LLM call fails (timeout, API error, malformed JSON), the -`AutoTagger` returns the original unmodified candidate list.

RRF score compression near 1.0 - -Because the normalization formula is `(k+1) / (k+rank)` with `k=60`, ranks 1–5 all -compress into the range `[0.871, 1.0]`. There is little score differentiation between -the top-ranked candidates. This is intentional (rank differences matter less than -presence/absence of token overlap) but means BM25 mode should not be used to produce -fine-grained competence similarity scores — only to separate matching (score > 0) from -non-matching (score = 0) candidates. - ---- - -### 5. Small per-person corpus causes IDF pathology — mitigated by global index - -BM25's IDF term rewards tokens that are rare across the corpus. When the BM25 index was -built per candidate (N = that person's competence count ≈ 5–30), any term appearing in -most documents had IDF ≤ 0, causing `rank_bm25` to return negative raw scores. After -`max(0.0, raw)` clamping, all candidates scored 0.0 — making the BM25 signal useless. - -**Fix (implemented):** The `Bm25Index` is now built once over the **union of all filtered -candidates' competences** in `Matcher.match()` before the per-candidate loop (see Key -Decision #2). This makes N equal to the total unique competence count across all -candidates, giving IDF proper signal. Per-candidate scoring filters the global results to -only that candidate's competence set. - -**Residual limitation:** If the filtered candidate pool itself is very small (e.g., 2–3 -candidates with few unique competences), IDF may still be weak. In practice this is -negligible since matching runs are always invoked against a meaningful pool of candidates. - ---- - -## Test Strategy - -### Unit tests - -1. **`tests/test_bm25.py`** - - `Bm25Index` with empty corpus → all scores 0.0 - - Exact match → score > 0 - - No token overlap → score == 0.0 - - Partial token overlap (multi-token queries) → partial score - - Case-insensitive matching ("Python" == "python") - - Tokenization edge cases: hyphens, parentheses, slashes - -2. **`tests/test_rrf.py`** - - Single list, single candidate → score 1.0 - - Single list, multiple candidates → scores normalized to [0, 1] - - All-zero list → returns empty / all zeros - - `k` parameter effect on score distribution - -3. **`tests/test_auto_tagger.py`** (new) - - LLM returns valid additions → `expand_competences()` appends them to existing list - - LLM returns empty additions → original list returned unchanged - - LLM call raises exception → original list returned unchanged (graceful degradation) - - LLM returns malformed JSON → original list returned unchanged - - Additions from LLM that are NOT in `required` are ignored - - `expand_competences()` never duplicates entries already in `existing` - - All tests use a mocked `AzureOpenAIClient` (no real LLM calls) - -4. **`tests/test_similarity.py`** (extended) - - `compute_competence_similarity()` with `use_bm25_search=True` - - Required "Python", candidate ["JavaScript"] → score 0.0 - - Required "Python", candidate ["Python"] → score 1.0 - - Required "Python" + "Machine Learning", candidate ["JavaScript", "TypeScript"] - → both scores 0.0, overall competence_score 0.0 - - With `use_bm25_search=True, use_auto_tagging=True`: mocked `AutoTagger` injects - "Machine Learning" into candidate ["ML"] → score > 0 - -### Integration test - -5. **`tests/test_matcher_integration.py`** (extended) - - With `use_bm25_search=True`: candidate with exact skills scores higher than - candidate with only semantically adjacent skills. - - The false-positive scenario (Python/ML vs JavaScript/TypeScript) is explicitly - tested. - - With `use_bm25_search=True, use_auto_tagging=True` (mocked LLM): candidate with - "ML" matches required "Machine Learning" after auto-tag expansion. diff --git a/bahn/teamlandkarte-mcp/openspec/changes/add-bm25-rrf-competence-matching/proposal.md b/bahn/teamlandkarte-mcp/openspec/changes/add-bm25-rrf-competence-matching/proposal.md deleted file mode 100644 index c9cdd60..0000000 --- a/bahn/teamlandkarte-mcp/openspec/changes/add-bm25-rrf-competence-matching/proposal.md +++ /dev/null @@ -1,288 +0,0 @@ -# Change Proposal: BM25 + RRF Competence Matching - -- **Change ID**: `add-bm25-rrf-competence-matching` -- **Status**: Proposed -- **Target**: `teamlandkarte-mcp` -- **Author**: Thomas Handke -- **Date**: 2026-02-26 - -## Summary - -Add an optional BM25-based competence matching strategy as an alternative to the existing -embedding-based similarity approach.

Embeddings excel at synonyms and -cross-language variants (e.g., German/English). The optional `use_auto_tagging` feature -bridges BM25's synonym and cross-language gap by having an LLM pre-expand the candidate -competence list — making the combination of BM25 + Auto-Tagging competitive with -embeddings while still eliminating false positives from semantic drift. - -### Why RRF for fusion - -Reciprocal Rank Fusion merges multiple ranked lists into one without requiring score -normalization. For each required competence query, we obtain a ranked list of candidate -competences. RRF then assigns each candidate a fused score based on its (1-based) rank in -one or more lists. - -RRF fused score formula (Cormack et al. 2009): - -``` -rrf_score(candidate) = Σ_i 1 / (k + rank_i(candidate)) -``` - -RRF is robust to score scale differences and has been widely validated in information -retrieval research as a high-quality fusion method. - -## What Changes - -### 1. New config parameter `matching.similarity.use_bm25_search` (boolean, default `false`) - -- When `false` (default): existing embedding-based strategy is used unchanged. -- When `true`: BM25 + RRF replaces embedding-based competence similarity. - Role similarity is **always** embedding-based (unchanged). - -### 2. New config parameter `matching.similarity.use_auto_tagging` (boolean, default `false`) - -- Only applies when `use_bm25_search = true`. When `false`, BM25 runs on the raw - candidate competence list (no LLM expansion). -- When `true`: before each BM25 scoring call, an LLM expands the candidate's competence - list with canonical forms of any required competences that are already covered by the - candidate's existing entries (via synonym, abbreviation, or cross-language equivalence). -- The expanded list is ephemeral — it is not written back to the database and does not - affect any other operation. - -### 3. New config parameter `azure_openai.chat_deployment` (string) - -- Azure deployment name of the chat model used for auto-tagging (e.g. `"gpt-4.1"`). -- Required only when `use_auto_tagging = true`. -- API key is read from environment variable `AZURE_OPENAI_LLM_API_KEY`. - -### 4. `AzureOpenAIClient` extended: LLM chat capability restored - -- Add `chat_completion(system: str, user: str) -> str` method supporting structured JSON - responses via Azure OpenAI chat completions API. -- Add `chat_deployment` and `llm_api_key` constructor parameters. -- This restores LLM capability removed in a previous change, now scoped exclusively - to auto-tagging. - -### 5. New module `src/teamlandkarte_mcp/matching/auto_tagger.py` - -Implements: -- `AutoTagger`: class that wraps the LLM client and executes the tagging prompt. -- `expand_competences()`: given `required: list[str]` and `existing: list[str]`, - returns `list[str]` — the combined list `existing + additions`, where `additions` - are the canonical required-competence names that the LLM identifies as already - covered by `existing` entries. -- Structured JSON output schema enforced via the Azure OpenAI `response_format` parameter. -- Google Docstrings on all public symbols. - -### 6. New module `src/teamlandkarte_mcp/matching/bm25.py` - -Implements: -- `Bm25Index`: builds an in-memory BM25 index over a corpus of competence strings. - Designed to be instantiated once over the global candidate pool (see item 8a below) - so IDF values are meaningful. Raw scores are clamped to `max(0.0, raw)` — terms with - negative IDF produce 0.0 rather than a spurious tiny positive value. -- `bm25_rank_competences()`: for a single required competence query, returns a ranked list - of `(candidate_text, score)` tuples. Convenience wrapper for standalone/test use. -- Pure Python, no external runtime dependencies beyond `rank_bm25` from PyPI. - -### 7. New module `src/teamlandkarte_mcp/matching/rrf.py` - -Implements: -- `reciprocal_rank_fusion()`: merges one or more ranked lists into a final score dict. -- `k` constant (default `60`, standard RRF value from Cormack et al. 2009). -- Returns `dict[str, float]` mapping candidate text → fused score in `(0, 1]` - (top-ranked candidate receives exactly `1.0`). - -### 8. `SimilarityEngine.compute_competence_similarity()` extended - -- Reads `use_bm25_search` and `use_auto_tagging` flags. -- Accepts an optional `global_index: Bm25Index | None` parameter (passed in by `Matcher`). -- When `use_bm25_search=True`: - 1. If `use_auto_tagging=True`: calls `AutoTagger.expand_competences()` to build the - expanded candidate list. - 2. Delegates to `_bm25_rrf_similarity()` with the (optionally expanded) candidate list - and the global index. -- `_bm25_rrf_similarity()` uses `global_index.rank(req)` filtered to the candidate's - competence set when `global_index` is provided, otherwise falls back to - `bm25_rank_competences(req, candidate)`. -- Output shape is **identical** to existing strategies: - `dict[required_competence → {score, best_match, rationale}]` -- Preserves the `Matcher` and scorer contracts unchanged. - -### 8a. `Matcher.match()` builds a global `Bm25Index` before the per-candidate loop - -When `use_bm25_search=True` and the filtered candidate pool is non-empty, `Matcher.match()` -collects the deduplicated union of all filtered candidates' competences and builds one -`Bm25Index` over that global corpus before the loop. The same index is passed to every -`compute_competence_similarity()` call. - -**Why this matters:** With a per-person corpus (N ≈ 5–30 entries), BM25 IDF is 0 or -negative for every term — all raw scores collapse to ≤ 0, and `max(0.0, raw)` clamping -makes every match appear as 0.0. A global corpus ensures N is large enough for IDF to -carry real signal. - -### 9. `SimilarityConfig` dataclass extended - -New fields: -- `use_bm25_search: bool = False` -- `use_auto_tagging: bool = False` - -### 10. `AzureOpenAIConfig` dataclass extended - -New fields: -- `chat_deployment: str = ""` -- (API key via `AZURE_OPENAI_LLM_API_KEY` env var) - -### 11. `config.py` parser extended - -Reads `matching.similarity.use_bm25_search`, `matching.similarity.use_auto_tagging`, -and `azure_openai.chat_deployment` from TOML.

Result is ephemeral. -- **Auto-tagging works in both directions**: both `find_matching_capacities` and - `find_matching_tasks` pass through `compute_competence_similarity()` and benefit. -- **Graceful degradation**: if the LLM call in `AutoTagger` fails for any reason, the - original candidate list is used unchanged. BM25 scoring continues. -- **LLM client restored**: `AzureOpenAIClient.chat_completion()` is re-added, scoped - exclusively to auto-tagging. The embedding-related API surface is unchanged. -- **Zero-out rule**: If all BM25 scores for a required competence are 0.0 (no token - overlap at all), the RRF score for that required competence is also 0.0. -- **Global index** *(revised)*: Originally the `Bm25Index` was to be built fresh per - `compute_competence_similarity()` call. This was identified as an IDF pathology: with - only one person's competences as the corpus, BM25 IDF is always 0 or negative for any - term that appears in every document (and with N=1 all terms do). The fix (Phase 9) builds - one `Bm25Index` over the union of all filtered candidates' competences before the loop - and passes it in as `global_index`. -- **Single ranked list**: Initial implementation fuses one BM25 ranked list per required - competence. The `reciprocal_rank_fusion()` signature accepts multiple lists for future - hybrid extension. -- **Output shape unchanged**: `_bm25_rrf_similarity()` returns the same - `dict[str, dict[str, object]]` shape as `_per_skill_similarity()`.

---- - -## Phase 6: Documentation - -### Task 6.1: Update `docs/architecture.md` -**File:** `docs/architecture.md` - -**Subtasks:** -- [x] Add section "BM25 + RRF + Auto-Tagging Competence Matching" under the matching/similarity section: - - Describe the three new modules (`auto_tagger.py`, `bm25.py`, `rrf.py`) - - Describe the auto-tag → BM25 → RRF pipeline and routing in `compute_competence_similarity()` - - Note that role similarity is unaffected - - Reference `use_bm25_search` and `use_auto_tagging` config keys - -### Task 6.2: Update `docs/semantic_similarity_tradeoffs.md` -**File:** `docs/semantic_similarity_tradeoffs.md` - -**Subtasks:** -- [x] Add BM25+RRF row to the strategy comparison table: - - Strengths: exact/lexical match, no false positives for non-overlapping skills - - Weaknesses: misses synonyms and cross-language variants (mitigated by `use_auto_tagging`) - - When to use: when skill names in the dataset are mostly canonical English terms -- [x] Add BM25+RRF+AutoTag row: - - Strengths: exact match + synonym/abbreviation/cross-language bridging via LLM - - Weaknesses: LLM latency per candidate, requires `AZURE_OPENAI_LLM_API_KEY` - - When to use: mixed-language or abbreviation-heavy skill datasets - -### Task 6.3: Update `docs/assistant_system_prompt.md` -**File:** `docs/assistant_system_prompt.md` - -**Subtasks:** -- [x] Add note on score interpretation when `use_bm25_search=true`: - - A `competence_score` of 0.0 means **no lexical token overlap** between required and candidate competences - - The score is not a semantic similarity — it is a lexical matching score - - Users should be informed when BM25 mode is active so they understand why cross-language synonyms may not match -- [x] Add note on `use_auto_tagging=true`: - - Auto-tagging bridges common synonym/abbreviation gaps (e.g. "ML" → "Machine Learning") - - A positive `competence_score` with auto-tagging enabled may reflect an LLM-inferred equivalence, - not a literal token match; the rationale field will say "BM25+RRF" regardless - -### Task 6.4: Update `README.md` -**File:** `README.md` - -**Subtasks:** -- [x] Add all three new config keys to the config reference section: - - `matching.similarity.use_bm25_search` (boolean, default `false`): Enables BM25+RRF lexical competence matching - - `matching.similarity.use_auto_tagging` (boolean, default `false`): Enables LLM pre-expansion before BM25 - - `azure_openai.chat_deployment` (string, default `""`): Chat model deployment name for auto-tagging -- [x] Document `AZURE_OPENAI_LLM_API_KEY` environment variable in the env-vars section -

---- - -## Phase 9: Architectural Fix — Global BM25 Index - -**Problem identified post-spec**: When `Bm25Index` was built per candidate (N = number of that -person's competences), IDF values were always 0 or negative for every term — the library -`rank_bm25` computes `log((N - df + 0.5) / (df + 0.5))`, and with N=1 every term has df=1, -yielding `log(0)` = negative. All BM25 scores were therefore ≤ 0, making the `max(0.0, raw)` -clamp produce a flat 0.0 for everything. The fix builds one global corpus from the union of -all filtered candidates' competences, ensuring N is large enough for IDF to be meaningful. - -### Task 9.1: Remove `1e-10` clamp in `bm25.py` -**File:** `src/teamlandkarte_mcp/matching/bm25.py` - -**Subtasks:** -- [x] Remove the special-case block that returned `1e-10` for zero/negative BM25 scores - when token overlap existed (a band-aid for the IDF pathology) -- [x] Replace with `max(0.0, float(raw))` — ubiquitous terms (negative IDF) simply score 0.0 -- [x] Update `Bm25Index` and `bm25_rank_competences()` docstrings to reflect the change - -**Acceptance:** -- A term present in every document of a sufficiently large corpus scores 0.0, not 1e-10 - ---- - -### Task 9.2: Add `use_bm25_search` property to `SimilarityEngine` -**File:** `src/teamlandkarte_mcp/matching/similarity.py` - -**Subtasks:** -- [x] Expose `use_bm25_search: bool` as a read-only property (or attribute) on `SimilarityEngine` - so `Matcher` can check it without accessing internal config directly - -**Acceptance:** -- `engine.use_bm25_search` returns the value of `engine.config.use_bm25_search` - ---- - -### Task 9.3: Thread `global_index` parameter through similarity layer -**File:** `src/teamlandkarte_mcp/matching/similarity.py` - -**Subtasks:** -- [x] Add `global_index: Bm25Index | None = None` parameter to `compute_competence_similarity()` -- [x] Pass it through to `_bm25_rrf_similarity()` -- [x] In `_bm25_rrf_similarity()`: when `global_index is not None`, call - `global_index.rank(req)` and filter the result list to only entries whose text is in - `set(candidate)`; otherwise fall back to `bm25_rank_competences(req, candidate)` - -**Acceptance:** -- `global_index.rank(req)` is called once per required competence, not once per candidate -- Results are correctly filtered to the current candidate's competence set -- Fall-back path (`global_index=None`) still works unchanged - ---- - -### Task 9.4: Build global corpus in `Matcher` before per-candidate loop -**File:** `src/teamlandkarte_mcp/matching/matcher.py` - -**Subtasks:** -- [x] Before the `for cap in filtered` loop: if `self._sim.use_bm25_search` and `filtered` - is non-empty, collect the deduplicated union of all candidates' competences into a list - `global_corpus`, instantiate `Bm25Index(corpus=global_corpus)` -- [x] Pass `global_index` to every `compute_competence_similarity()` call inside the loop -- [x] When `use_bm25_search=False` (or `filtered` is empty): `global_bm25_index = None` - (no-op, existing behaviour) - -**Acceptance:** -- A corpus of N candidates' competences is built once, not N times -- Candidates with no overlap with required competences still score 0.0 -- Candidates with overlap score > 0.0 (IDF is meaningful because N >> 1 in the global corpus) - ---- - -### Task 9.5: Update tests for global index -**Files:** `tests/test_bm25.py`, `tests/test_similarity.py`, `tests/test_matcher_integration.py`, `tests/test_matching_refinements.py` - -**Subtasks:** -- [x] `test_bm25.py`: update small-corpus tests to use ≥ 5-doc corpora so IDF is positive;

-> Change: `add-capacity-to-task-matching-tools` -> -> Status: **Implemented** - -## Phase 1: Requirements + Configuration decisions - -- [x] 1.1 Define `list_free_capacities` ordering precisely: - - order by most recent `creation_date` (descending) -- [x] 1.2 Confirm “Owner/Team” display: - - use `owner_name` (contains the team name) -- [x] 1.3 Introduce a new role inference tool and remove the old: - - add `infer_primary_role(task_id? | task_text?)` that returns the single closest role as a Markdown table with `Role | Similarity` columns - - remove `infer_roles(...)` MCP tool completely (no deprecation period) - - remove `TaskAnalyzer.extract_ranked_roles()` method completely - - update `extract_requirements()` and other callers to use new primary-role inference -- [x] 1.4 Add configuration for competence inference: - - `matching.inference.max_competences` (int, default: 8; if not specified, no limit) - - `matching.inference.min_similarity` (float in [0,1], default: 0.4; if not specified, no threshold) - - at least one parameter MUST be specified to avoid unbounded results - - selection rule: pick top X among those >= threshold when both are set -- [x] 1.5 Define startup-only refresh behavior: - - on startup embed only cache-missing role/competence vocab entries - - on startup embed **all open tasks** (title+description by task_id) - - at runtime still embed on-demand for misses (strict failure semantics) - -## Phase 2: Data Lake queries (roles, competences, capacities) - -- [x] 2.0 Verify Data Lake schema: - - confirm `teamlandkarte_v_capacity_roles_latest` has columns: `name`, `active`, `staffing_board_relevant` - - confirm capacities view has `creation_date` column -- [x] 2.1 Add `TrinoClient.get_recent_free_capacities(limit)` query returning: - - `capacity_id`, `owner_name` (team), `role_name`, `creation_date`, `begin_date`, `end_date`, `competences[]` - - ordering: `creation_date DESC` -- [x] 2.2 Add `TrinoClient.get_capacity_by_id(capacity_id)` query returning the same fields. -- [x] 2.3 Add `TrinoClient.get_all_role_names()`: - - source: `teamlandkarte_v_capacity_roles_latest` - - filter: `active=true AND staffing_board_relevant=true` - - return unique, non-empty role names -- [x] 2.4 Add `TrinoClient.get_all_competence_names()`: - - source: `beschaffungstool_kmp_skill_latest.skillname__c` - - return unique, non-empty competence names -- [x] 2.5 Add unit tests for SQL read-only guard + query shape (where applicable). - -## Phase 3: Startup embedding preload (vocabularies + tasks) - -- [x] 3.1 Define stable cache-key scheme (explicit format as documented in design.md): - - role vocab entries: `f"role_vocab:{model}:{dims}:{normalized_role_name}"` - - competence vocab entries: `f"comp_vocab:{model}:{dims}:{normalized_competence_name}"` - - task text embeddings by task_id: `f"task_id:{model}:{dims}:{task_id}"` -- [x] 3.2 Implement `VocabularyCache` component (`src/teamlandkarte_mcp/matching/vocabulary.py`): - - fetch role vocabulary + competence vocabulary from Trino - - normalize/deduplicate - - embed only cache-missing entries (batch + chunking via `SimilarityEngine.prefetch_embeddings(...)`) - - store into SQLite embedding cache - - keep in-memory memoization for fast repeated inference - - invoked from `build_server()` after DB + similarity engine init -- [x] 3.3 Implement a “task embedding preload” routine executed on startup: - - fetch **all open tasks** (no limit) - - build `task_text = title + "\n\n" + description` (title optional) - - embed only cache-missing `task_id` vectors - - store into SQLite embedding cache -- [x] 3.4 Runtime fallback: - - if a role/competence/task embedding is missing during a tool call, embed on-demand (strict semantics) -- [x] 3.5 Tests: - - preload embeds only cache misses - - preload writes to SQLite - - missing-at-runtime triggers on-demand embedding - -## Phase 4: Embedding-only inference (roles + competences) - -- [x] 4.1 Implement primary role inference against role vocabulary: - - input: combined `title+description` (or description-only for ad-hoc) - - output: single closest role with similarity score as Markdown table: `Role | Similarity` -- [x] 4.2 Add a new MCP tool: - - `infer_primary_role(task_id? | task_text?)` - - returns: Markdown table `Role | Similarity` (single best matching role) -

-## Phase 5: Rework task validation (embedding-only) - -- [x] 5.1 Replace chat-based extraction in `validate_task_requirements` / `extract_requirements_from_task` with embedding-based inference: - - roles: infer primary role via role vocabulary (Markdown table output) - - competences: infer competences via competence vocabulary with max X and threshold (Markdown table output) -- [x] 5.2 Update output format: - - keep current table-first display - - add inferred primary role as Markdown table: `Role | Similarity` (single row) - - add inferred competences as Markdown table: `Competence | Similarity` (descending order by similarity) -- [x] 5.3 Tests: - - validation uses embeddings path only (no chat calls) - - respects max X and threshold rules - - output includes role and competence similarity tables - -## Phase 6: New MCP tools (capacity browsing + capacity→task matching) - -- [x] 6.1 Implement `list_free_capacities(limit=20)`: - - ordering: `creation_date DESC` -

- include a “Next steps” pointer to `find_matching_tasks(capacity_id=...)` -- [x] 6.3 Implement `find_matching_tasks(capacity_id)`: - - signature: takes only `capacity_id` (no optional params) - - fetch capacity + all open tasks - - infer each task’s primary role via embedding similarity (title+description) - - infer each task’s competences via embedding similarity (title+description) with max/threshold - - compute a similarity score (role + competences) and categorize results - - return output as Markdown table with columns: - - `task_id`, `Title`, `Required Competences`, `Availability`, `Score`, `Category` - - results are sorted by similarity score (descending) - - output structure matches `find_matching_capacities` (includes summary counts table + results table for first non-empty category) - - paginated via same search session conventions used by `find_matching_capacities` -- [x] 6.4 Tests for new tools: - - `list_free_capacities`: ordering by `creation_date DESC`, empty-table handling - - `get_capacity_details`: not-found handling, "Next steps" section - - `find_matching_tasks`: categorization (Top/Good/Partial/Low), search session conventions, table structure, score sorting - -## Phase 7: Remove Azure chat API - -- [x] 7.1 Remove chat config fields and environment variables if no longer needed (`AZURE_OPENAI_LLM_API_KEY`, chat deployment, chat codepaths). -- [x] 7.2 Delete/retire chat client methods and `TaskAnalyzer` chat-based methods. -- [x] 7.3 Update docs to remove chat setup instructions. -- [x] 7.4 Ensure all gates pass (ruff/mypy/pytest). -

-1. `get_task_details` should return a concise markdown summary (table) of the task plus description below. -2. Introduce a dedicated tool `infer_roles` for role inference from either a DB task ID or free-text description. -3. `validate_task_requirements` should return a single comparison table plus a short written summary. -4. When a user requests a person search without providing project/task details, switch to a **step-by-step guided capture** (no "all questions at once"). -5. Enforce a **mandatory confirmation step** before triggering matching, for both free-text and guided capture / structured entry. -6. Fix a suspected competence matching regression (cloud expert + AWS scoring ends up `Low`), likely caused by extraction/matching issues. -7. Improve search session robustness for pagination/filtering: - - search tools emit a JSON block containing `search_id`/`filter_id` - - non-UUID `search_id` inputs are rejected early with a clear message - - internal tracking of the latest search id (session state) for diagnostics only; **no** "get last search id" tool is provided -8.

If that still yields no role above threshold (or no vocab match), role_score MUST be `0.0`. -- **`is_fully_available` without explicit date params:** `filter_search_results(..., is_fully_available=true)` MUST work even when `availability_date_start/end` are omitted by using reference dates stored in the search context. -- **Availability % with open-ended other_end:** If the reference period is fully defined and `other_end is None`, availability percentage MUST still be computed (overlap is well-defined until ref_end). -- **Overall score formula (fixed):** `overall_score` MUST be a weighted mean of role_score and competence_score using config weights: -

-## Risk Mitigation - -**Risk**: Azure API downtime → System unusable -**Mitigation**: Document SLA expectations; consider adding a simple health check tool/endpoint and a clear user-facing error message (`AzureAPIError`). - -**Risk**: Unexpected high costs -**Mitigation**: Enable embedding cache (default); monitor costs weekly; set Azure budget alerts. - -**Risk**: Embedding cache grows too large -**Mitigation**: Run periodic cleanup; set reasonable TTL (default 30 days); ensure cache DB files stay ignored. - -**Risk**: Secrets accidentally committed (`config.toml`, `.env`, caches) -**Mitigation**: Keep `config.toml` and `.env` ignored; review `git status` before commit; run a secret scan locally (e.g. `git grep` for key patterns) before merging. - -**Risk**: Migration breaks existing deployments -**Mitigation**: Provide clear migration guide; test migration path manually; run integration tests against Azure in at least one real environment. - -## Success Criteria - -- [x] Unit tests pass (non-integration) -- [ ] Integration tests pass (`pytest -m integration`) in an environment with valid Azure credentials -- [ ] Server starts successfully with Azure credentials -- [ ] Matching results show improved semantic understanding vs. heuristics -- [ ] Embedding cache demonstrates significant performance improvement on repeated searches -- [ ] Cost tracking shows accurate estimates -- [ ] Documentation complete and clear -- [ ] Repo clean: no secrets or local config files tracked (verify before merge) -

- `availability_date_start` / `availability_date_end`: override the - reference window for availability filtering - - `is_fully_available`: - - for capacity_search: capacity must fully cover the reference window -

- `task_text_filter`: case-insensitive substring search in task title - and description - - `task_competence_filter`: case-insensitive match against task - `required_competences` (inferred) and `skills` (DB) -
