This PR optimizes recommendation catalog initialization and policy validation in src/skills/catalog.rs:

  • Uses std::sync::OnceLock<ResolvedSkillCatalog> in load_catalog to memoize the baseline catalog parsed from compile-time asset catalog.v1.toml, avoiding repeated TOML parsing and policy validation across CLI commands and skill operations.
  • Deduplicates and sorts APPROVED_EMBEDDED_EXTERNAL_SKILL_IDS alphabetically, switching classify_embedded_recommendation_source from linear search (.contains()) to binary search (.binary_search().is_ok()).
  • Adds test_approved_external_skill_ids_is_strictly_sorted_and_unique unit test to enforce array sorting and uniqueness.

…ed skill ids

- Memoize embedded recommendation catalog baseline in `load_catalog` using `std::sync::OnceLock` to eliminate redundant TOML parsing and policy validation of `catalog.v1.toml` across invocations.
- Deduplicate and sort `APPROVED_EMBEDDED_EXTERNAL_SKILL_IDS` alphabetically, replacing $O(N)$ linear scans in `classify_embedded_recommendation_source` with $O(\log N)$ binary search (`binary_search`).
- Add a unit test verifying `APPROVED_EMBEDDED_EXTERNAL_SKILL_IDS` remains strictly sorted and unique.

Review Change Stack

📝 Summary

Summary by CodeRabbit

  • New Features

    • Added support for additional approved embedded skills, including integrations and framework-specific patterns for Clerk, Prisma, Vercel, Django, SQLAlchemy, and more.
  • Performance

    • Improved skill catalog loading by caching parsed catalog data, reducing repeated processing.
    • Accelerated validation of approved skill identifiers for more efficient catalog checks.
  • Quality

    • Improved consistency of the approved skill list by enforcing sorted, unique entries.

Walkthrough

The embedded skill allowlist is sorted, deduplicated, expanded, and checked with binary search. Embedded catalog parsing is cached with OnceLock, and callers receive cloned catalog values.

Changes

Embedded catalog optimizations

Layer / File(s) Summary
Sorted allowlist and lookup validation
src/skills/catalog.rs
The approved skill ID list is reordered, expanded, and deduplicated. Classification uses binary_search. A test verifies strict sorting and uniqueness.
Memoized catalog loading
src/skills/catalog.rs, .agents/journal/bolt.md
EmbeddedSkillCatalog::default uses load_catalog(None). load_catalog caches the parsed baseline with OnceLock and clones it for callers. The journal records the optimization.
Estimated code review effort: 2 (Simple) ~10 minutes

Merge Risk: 🔵 Low · up to 35e9e

Invalid embedded catalog data could terminate catalog-dependent commands instead of returning a normal error. The current asset is valid, so the immediate merge risk is bounded.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Preserve fallible catalog initialization.

load_catalog still returns Result, and callers such as suggest propagate that result. This expect now turns malformed embedded TOML or strict policy-validation failures into a process panic during the first load. Keep the cached initialization fallible so callers can report the existing error instead of terminating.
