repo-stats-autoupdate

What this skill does

Reads the authoritative sources for the ctx repo's key numbers and patches README.md in place so badges and inline counts never drift:

Number	Source of truth
Skills	~/.claude/skill-wiki/graphify-out/graph.json — count nodes where type == "skill"
Agents	same file — count nodes where type == "agent"
Graph nodes	len(graph["nodes"])
Graph edges	len(graph["edges"]), formatted as 642K / 1.2M
Communities	graph/communities.json → total_communities
Converted pipelines	~/.claude/skill-wiki/converted/ subdir count
Tests	checked-in README/docs inventory by default; set CTX_UPDATE_REPO_STATS_LIVE_TESTS=1 to refresh from pytest --collect-only -q

Fields that can't be resolved (e.g. wiki not deployed) are left untouched — the updater never blocks a commit.

How to use it

One-time install (per clone):

git config core.hooksPath .githooks

After that, every git commit runs .githooks/pre-commit which calls the updater and re-stages README.md if any number drifted.

Manual run:

python src/update_repo_stats.py          # patch README
python src/update_repo_stats.py --check  # exit 1 if stale (for CI)
CTX_UPDATE_REPO_STATS_LIVE_TESTS=1 python src/update_repo_stats.py  # refresh test inventory

When NOT to use it

• When you've deliberately phrased a number descriptively (e.g. "over 1,700 skills") — the regex patterns only match exact digits, so prose phrasings are safe, but double-check after big imports.
• When the wiki isn't deployed locally. The updater degrades gracefully: it prints a warning and skips fields it can't resolve. It does not invent numbers.

Known gaps (intentionally out of scope)

• Does not rebuild the graph or wiki. Rebuilding graph/wiki-graph.tar.gz takes minutes and churns a large artifact — too heavy for per-commit. Run ctx-wiki-graphify, then python src/validate_graph_artifacts.py --deep, and repack the tarball manually when the skill catalog changes materially.
• Does not verify graph integrity. If graphify-out/graph.json is corrupt, you'll get junk numbers. Run the wiki health check (python src/wiki_orchestrator.py --check) separately.
