Problem

Project-specific skills can disappear from learn -s results when query terms are spread across fields and generic matches fill the result limit.

The API truncated project results before the MCP server could rank them against bundled skills. Follow-up requests could not recover every relevant result.

Long search queries could also expand into an unbounded number of scoring expressions and follow-up file queries.

Changes

  • Scores project skills before applying the 10-result limit.
  • Uses the same relevance scale for project and bundled skills.
  • Returns snippets from the files that contributed the strongest search scores.
  • Prefilters matching candidates before computing scores across the accessible catalog.
  • Restricts search fields to an allowlist.
  • Uses ordered plural rules while protecting status and keeping derived stems at least five characters long.
  • Scores the eight longest informative tokens in both implementations, with stable input-order tie-breaking.
  • Documents the eight-keyword limit in the runtime command syntax and MCP README.
  • Limits search traffic to 60 requests per minute and 600 requests per hour for each user.

How did you test this code?

  • Ran MCP unit tests for skill search, exec command handling, and instruction snapshots.
  • Ran Ruff, MCP type checking, linting, formatting, and Markdown linting.
  • Not run after the final review fixes: Django skill API tests. The local Postgres instance rejected the configured posthog credentials.
  • OpenAPI generation and strict CI preflight passed before the final review round. CI will re-run them against the final branch.

👉 Stay up-to-date with PostHog coding conventions for a smoother review.

Score project skills server-side so multi-word matches compete with bundled skills before either source is truncated.

⚠️ Trunk lane — backend Python lane

This PR is assigned to the backend Python lane. It runs backend Python tests and may merge in parallel with PRs in other lanes.

✅ Complexity (TypeScript) — clean

Cyclomatic complexity above the limit in changed typescript files (10 for production files, 15 for test files). Warn only: worth simplifying when you next touch these functions.

✅ Duplication (Python) — clean

New Python code duplication introduced by this branch. Fails at 70+ tokens in app code, or 150+ tokens when both copies live in test files. Advisory while the gate proves itself: extract a shared helper instead of copying.

✅ Toolbar bundle — eager 2.36 MiB within budget

What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

Known gaps: lines covered only by Temporal tests show as uncovered; core line numbers may drift if master changed the same file.

📝 Walkthrough

Walkthrough

Backend skill search now computes weighted relevance scores across skill fields and matching files. It supports constrained stemming, exact-name bonuses, result limits, ordered excerpts, throttle limits, and serialized scores. MCP types require the score, and project search preserves the backend value without fallback ranking. Local ranking selects the strongest file matches and narrows stem variants. Tests cover ranking, score propagation, excerpts, limits, and stemming.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to 0d459

Search results may show a less relevant excerpt than the file driving the result’s ranking, reducing search usefulness. The change is otherwise mergeable with bounded follow-up.

427-475: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Exclude SKILL.md from backend file-path scoring.

rankSkill excludes SKILL.md from filePathScore, but _get_search_queryset scores every file path. For the reachable query skill, the backend therefore adds 240 + 120 = 360 to every project skill because its path is SKILL.md, even when no skill content matches. That score can place an irrelevant project result above a more relevant PostHog result with only a 240-point body match before the shared limit of 10.

The 5,000-point exact-name bonus and the other visible weights match. The backend file-path boundary is the single correction owner.

Suggested fix
         file_path_score = Coalesce(
             Subquery(
-                skill_files.annotate(score=_skill_search_field_score("path", query, tokens, 120))
+                skill_files.exclude(path="SKILL.md")
+                .annotate(score=_skill_search_field_score("path", query, tokens, 120))
                 .order_by("-score")
                 .values("score")[:1],

The ranking implementation appears correct, but the required API documentation update must be included before merging.

Run the updated Django tests before merge.

If PostgreSQL credentials are available, run pytest products/skills/backend/api/test/test_skills.py -k 'search_skills' and address any failures. The repository guidelines require updated tests to pass with pytest.

523-525: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Restrict the singular us exception.

The current exception treats bayous as singular and does not generate the bayou variant. A skill whose searchable text contains only bayou may therefore not match a bayous query. Distinguish singular terms such as status from valid plural forms, and add regression coverage for both cases.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Select snippets by per-file relevance score.

fileContentScore retains the strongest companion-file score, but snippets still retains the first two matching files in iteration order. If a weaker file precedes a stronger file, the result score reflects the stronger file and the excerpt comes from the weaker file. Store scored snippet candidates and select the highest-scoring candidates before applying MAX_GLOBAL_SNIPPETS.
