Runtime Evidence

context-kit

A context-engineering plugin pack for GitHub Copilot CLI, Microsoft's APM (Agent Package Manager), and Claude Code — getting the right information in front of an agent and keeping the wrong information out. It bundles complementary retrieval modalities — lexical, structural, code-intelligence, structured-data, history, semantic (RAG), and graph — plus a routing agent that picks and composes them. The provided tooling runs locally, and the RAG layer keeps your corpus on your machine. Around that spine it adds plan-execute (a strong model plans; cheaper subagents execute), context-steering (put each rule at the cheapest layer that still fires), verify (read-only claims and change-impact analysis), runtime-evidence (controlled escalation when static checks cannot settle a runtime claim), context-handoff (bounded cross-session task state), and plugin-forge (author and quality-check portable plugins). The marketplace ships ten plugins.

📖 Documentation site — install guides, architecture, and a page for every plugin.

All three hosts install the same plugins directly from one marketplace — GitHub Copilot CLI via copilot plugin, APM via apm install, and Claude Code via /plugin — no manual copying of skill folders. The catalog ships in Claude Code's marketplace schema, which Copilot and APM read too.

GitHub Copilot install

GitHub Copilot CLI installs these plugins directly from the marketplace — the same OWNER/REPO this repo publishes:

copilot plugin marketplace add mbeacom/context-kit
copilot plugin install code-search@context-kit      # auto-installs retrieval-core
copilot plugin install local-rag@context-kit
copilot plugin install obsidian@context-kit
copilot plugin install plan-execute@context-kit   # plan-big/execute-small orchestration
copilot plugin install context-steering@context-kit
copilot plugin install verify@context-kit          # auto-installs retrieval-core
copilot plugin install runtime-evidence@context-kit # pulls verify, then retrieval-core
copilot plugin install context-handoff@context-kit  # pulls verify, then retrieval-core
copilot plugin install plugin-forge@context-kit

See docs/GITHUB_COPILOT.md for details, including the local-rag CLI bootstrap outside Claude Code (Copilot does not run the plugin's SessionStart hook).

APM (Agent Package Manager) install

APM installs the same plugins from the same marketplace, adding a committed lockfile, a pre-install security scan, transitive dependency resolution, and cross-harness deploy. Register the marketplace, then install:

apm marketplace add mbeacom/context-kit
apm install code-search@context-kit      # also pulls retrieval-core (the spine)
apm install local-rag@context-kit
apm install obsidian@context-kit
apm install plan-execute@context-kit
apm install context-steering@context-kit
apm install verify@context-kit           # also pulls retrieval-core
apm install runtime-evidence@context-kit # pulls verify, then retrieval-core
apm install context-handoff@context-kit  # pulls verify, then retrieval-core
apm install plugin-forge@context-kit

APM reads the repo's .claude-plugin/marketplace.json and each plugin's native layout directly; each per-plugin apm.yml carries APM metadata and dependencies. runtime-evidence and context-handoff depend on verify, which transitively pulls retrieval-core. See docs/APM.md for targets, the local-rag bootstrap (APM does not run Claude's SessionStart hook), and maintainer notes.

Claude Code install

/plugin marketplace add mbeacom/context-kit

Then install what you need (installing code-search auto-installs retrieval-core):

/plugin install code-search@context-kit     # lexical/structural/data/history search
/plugin install local-rag@context-kit        # local semantic search (turbovec + ollama)
/plugin install obsidian@context-kit          # Obsidian vault → RAG bridge
/plugin install plan-execute@context-kit      # plan-big/execute-small orchestration
/plugin install context-steering@context-kit  # place guidance at the cheapest layer
/plugin install verify@context-kit            # claims + change impact (pulls retrieval-core)
/plugin install runtime-evidence@context-kit  # controlled runtime evidence (pulls verify)
/plugin install context-handoff@context-kit   # manual cross-session handoffs (pulls verify)
/plugin install plugin-forge@context-kit      # author portable plugins
