Teach Claude your codebase. Keep it taught. Plugin that builds and maintains a curated index of multiple repositories, reviewer-in-the-loop on every change.
Answers questions about nick-railsback/skill-engine — the Claude Code plugin that scaffolds and maintains 'contextualizer' skills. Covers its workflows (bootstrap, discover, refresh, review, apply, self-audit, status), the source-paths.json and reference-file artifact contract, the four reference invariants and…
Answers questions across the configured sources. References load on demand from references/. Use when working in any of this contextualizer's source domains.
Answers questions about the LangChain Python ecosystem — the langchain-ai/langchain monorepo (langchain-core, v1 agents, langchain-classic, in-tree partners, text-splitters) plus companion repos LangGraph, LangSmith SDK, Deep Agents, out-of-tree partner monorepos langchain-google and langchain-aws, and the…
Answers questions about the official Model Context Protocol (MCP) Python SDK (mcp package on PyPI, modelcontextprotocol/python-sdk on GitHub). Tracks the main branch (v2 pre-alpha — MCPServer/snakecase/constructor-on handlers). Use when working with MCP servers or clients in Python, debugging v1→v2 migrations, or…
Use when a staged proposal has been reviewed and signed off — REVIEW.md Step 3 ticked reviewed or provisional — and is ready to promote into the live contextualizer.
Use when the local /.cache/skill-engine/ clone cache should be cleared — to free disk, drop stale git-managed clones or web-doc snapshots, or force a clean re-fetch on the next DISCOVER/REFRESH. Always dry-runs first.
Use when a staged proposal doesn't warrant promotion, or was ticked reject in REVIEW.md Step 3, to remove the proposed staging directory without touching the live contextualizer.
Use when a contextualizer's reference coverage needs to grow against its registered sources — a fresh contextualizer's first pass, quarterly upkeep, or whenever the catalog is lagging what users are asking — to propose new reference files.
Use when an existing contextualizer's references may have drifted from current upstream state — typically weekly, or whenever a few days of upstream changes have accumulated — to bring them back into agreement.
Use when checking an existing contextualizer for drift — stale dates, broken URLs, catalog/content disagreement, and more — every two to four weeks; read-only unless the user opts into fixing the deterministic checks.
Use when picking up a contextualizer after a gap, or checking reference freshness and pending review work at a glance — read-only, safe to run anytime.
When the user mentions skill-engine or "the engine" without naming a specific workflow, or wants first-run setup. Inspects .claude/skills/-context/ install state (and any pending -context.proposed/ proposals) across all three install levels, then dispatches to engine-bootstrap when no contextualizer exists, to…
