Skills

The opencodehub Claude Code plugin ships two families of skills:

• Analysis skills (pre-existing) — codehub-exploring, codehub-impact-analysis, codehub-debugging, codehub-refactoring, codehub-pr-review, codehub-guide. These answer questions about the code graph.
• Artifact skills (new in this release) — turn graph queries into committed Markdown. Documented below.

All artifact skills ship under plugins/opencodehub/skills/ and are auto-discovered by Claude Code when the plugin is installed.

Artifact skills

codehub-document Primary artifact generator. Single-repo and group mode, 4-phase orchestration, .docmeta.json sidecar.

codehub-pr-description Draft a PR body from detect_changes + verdict + owners + findings-delta. Refuses on a clean tree.

codehub-onboarding ONBOARDING.md with a graph-centrality-ranked reading order and an end-to-end process walk.

codehub-contract-map Group-only. Consumer/producer contract matrix across a repo group, with Mermaid flow.

codehub-code-pack Deterministic 9-item code-pack BOM for a repo or group — byte-identical given the same (commit, tokenizer, budget).

How they compose

The five skills share the OpenCodeHub MCP toolkit. codehub-document is the only skill that dispatches subagents; the others are linear. The four documentation skills write to .codehub/ by default (gitignored), with --committed opting in to a git-tracked path; codehub-code-pack writes a deterministic code-pack BOM via pack_codebase.

Invocation cheatsheet

Trigger phrase	Fires
”document this repo” / “regenerate the architecture docs”	codehub-document
”document the <group> group” / “map the repos in <group>”	codehub-document --group <name>
”write the PR description” / “summarize this branch for review”	codehub-pr-description
”draft release notes for HEAD”	codehub-pr-description
”write ONBOARDING.md” / “what should a new hire read first”	codehub-onboarding
”map the contracts” / “show the contract matrix for <group>”	codehub-contract-map <group>
”pack this repo for an LLM” / “deterministic code pack”	codehub-code-pack

Discoverability hooks

The plugin hooks have been extended to surface the artifact skills at the right moments:

• After codehub analyze completes, the CLI prints: Try: /codehub-document · /codehub-onboarding · /codehub-contract-map <group>
• After git commit|merge|rebase|pull triggers auto-reindex, if .codehub/docs/.docmeta.json exists and its codehub_graph_hash differs from the live hash, a non-blocking systemMessage suggests /codehub-document --refresh. Never auto-regenerates — regeneration spends LLM credits and requires user consent.
• mcp__opencodehub__verdict and mcp__opencodehub__detect_changes responses include next_steps: [{suggest: "codehub-pr-description"}] when a non-empty diff is present.
