skill-engine

Promote a reviewed proposal into the live contextualizer.

Propose new reference files for registered sources.

Register one new reference in an existing contextualizer without a full discover pass.

Refresh a contextualizer's references against current upstream state.

Audit a contextualizer for drift (read-only).

List a contextualizer's reference freshness and any pending review work.

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 discover / refresh / status / self-audit / new-reference when one is present, or asks which workflow when the choice is ambiguous.

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 docs.langchain.com source. Includes a thin orientation pointer for the LangChain.js port. References load on demand from references/.

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`/snake_case/constructor-`on_*` handlers). Use when working with MCP servers or clients in Python, debugging v1→v2 migrations, or answering questions about tools, resources, prompts, transports, OAuth, or experimental tasks. References load on demand from `references/`.

Delete the skill-engine clone cache (`~/.cache/skill-engine/`), with a dry-run preview first.

Scaffold a new contextualizer from one or more source URLs or local paths.

Set an engine-wide config value (currently the `review` diff tool).

Discard a staged proposal without promoting it.

Review a staged proposal and sign off before applying it.
