opencodehub: Skill for Claude Code

.claude/skills/codehub-document/SKILL.md

codehub-document is a skill for Claude Code from theagenticguy/opencodehub. It costs 159 tokens per session (3,176 once invoked), scanned A, original, Apache-2.0.

A documentation tool for creating a linked set of Markdown files that explains a codebase, its architecture, and its modules.

In plain words
What is it for?
Use it to generate or refresh repository documentation, architecture books, module maps, and documentation for groups of repositories.
Why use it?
It turns an indexed repository into a structured reference, so developers do not have to piece the system together manually.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: model in frontmatter; mentions subagents; mentions Claude Code.

This is theagenticguy/opencodehub's own configuration. It tells Claude Code how to work on opencodehub itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything opencodehub configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

codehub-document scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.

codehub-document

Primary artifact generator. Produces a tree of cross-linked Markdown under .codehub/docs/ (single-repo) or .codehub/groups/<name>/docs/ (group mode) using a three-phase orchestration: Phase 0 parallel precompute waves → Phase 1 file-level subagent fan-out (one packet = one output file) → Phase 2 deterministic cross-reference assembly.

Model policy. This skill runs on Sonnet by default. Bump to Opus in two cases:

  1. --refresh --group combined — the pruning + partial fan-out across members needs the extra judgment.
  2. Any individual packet may set model: opus in its frontmatter to opt into Opus for synthesis-heavy roles. The cross-repo skeletons (doc-cross-repo-*) and doc-analysis-risk-hotspots typically do this; full-scan single-repo packets stay on Sonnet.

Preconditions (check before Phase 0)

  1. mcp__codehub__list_repos returns the target. If not, emit Run codehub analyze first — repo <name> is not indexed. and stop.
  2. codehub status reports fresh. If stale, emit Run 'codehub analyze' first — index is stale and stop.
  3. Group mode only: mcp__codehub__group_status({group}) must return fresh: true for every member. If any member is stale, abort and name each stale repo.

Arguments

  • [output-dir] (optional positional) — where to write. Default is .codehub/docs/ (gitignored). With --committed, default flips to docs/codehub/ and the skill does not add a .gitignore entry.
  • --group <name> — enable group mode. Phase 0 calls group_list + group_status + group_contracts + group_query. Phase CD dispatches doc-cross-repo.
  • --committed — write under docs/codehub/ (or user-supplied path) instead of .codehub/docs/. Does not touch .gitignore.
  • --refresh — consult .docmeta.json, identify stale sections by comparing max(mtime(section.sources[])) against section.mtime, and dispatch exactly one file-level subagent per stale section (re-seeding its packet from templates/agents/<role>.md). Phase 2 always re-runs.
  • --section <name> — regenerate one named section (e.g., architecture/system-overview). Dispatches exactly one subagent with one skeleton and re-runs Phase 2. Useful for targeted updates.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
