analyze-repo

analyze-repo is a skill for Claude Code, Codex from steve-magne/hookstack. It costs 112 tokens per session (2,704 once invoked), scanned A, original, MIT.

A source-analysis workflow for extracting agent hooks from a GitHub repository, article, or documentation page. Agent hooks are automated actions triggered by events during coding work.

In plain words
What is it for?
Use it to scan a repository or documentation URL, find hook definitions and related commands, and add the extracted hooks to the catalogue.
Why use it?
It turns an external source into structured entries for the Hookstack catalogue. It also detects supported hook configuration files and handles sources that contain no hooks.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside the plugin that ships it — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

analyze-repo scanned grade A with 1 finding 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 5d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/fetch-doc-sources.mjs, scripts/fetch-hook-sources.sh, scripts/merge-hooks.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

How it starts

The opening of the file, as written. The whole thing — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pipeline d'analyse pour $ARGUMENTS. Exécuter depuis la racine du projet hookstack.

Phase 0 — Détection du type de source

if echo "$ARGUMENTS" | grep -qE 'github\.com/[^/]+/[^/]+'; then
  SOURCE_TYPE="github"
else
  SOURCE_TYPE="documentation"
fi
echo "Source détectée : $SOURCE_TYPE"

Brancher sur la phase correspondante selon SOURCE_TYPE.


Phase 1+2 — [GitHub] Découverte et récupération (script, 0 token LLM)

Exécuter uniquement si SOURCE_TYPE="github".

DATA=$(bash .claude/skills/analyze-repo/scripts/fetch-hook-sources.sh "$ARGUMENTS" registry/registry.json)
echo "$DATA"
  • Si DATA contient la clé "error" → afficher l'erreur et s'arrêter.
  • Si has_hooks est false → écrire [] dans /tmp/hookstack-hooks-new.json et passer directement à la Phase 3.5.

Layouts de config supportés (le script détecte automatiquement, config_paths liste les fichiers trouvés) :

  • .claude/settings.json / .claude/settings.local.json — Claude Code classique (clé hooks)
  • .claude/hooks.json / hooks.json — config hooks seule à la racine
  • hooks/hooks.json — layout plugin/marketplace, commandes type ${CLAUDE_PLUGIN_ROOT}/hooks/… (ex. AgriciDaniel/claude-seo)

Les scripts associés sont fournis dans hook_scripts (.claude/hooks/* toujours ; hooks/* quand le layout plugin est détecté).


Phase 1b — [Documentation] Récupération de la page (script, 0 token LLM)

Exécuter uniquement si SOURCE_TYPE="documentation".

DATA=$(node .claude/skills/analyze-repo/scripts/fetch-doc-sources.mjs "$ARGUMENTS" registry/registry.json)
echo "$DATA"
  • Si DATA contient la clé "error" → afficher l'erreur et s'arrêter.
  • DATA contient : { source_type, url, title, content, existing_slugs }.
  • content est le texte extrait de la page (HTML strippé, sections hook-pertinentes prioritaires).

Phase 3 — Extraction des hooks (seule phase LLM)

À partir du DATA ci-dessus, produire des entrées JSON selon le mode actif.

Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

analyze-repo is a skill published in the GitHub repository steve-magne/hookstack (7 stars, last pushed 3d ago), licensed MIT. It adds 112 tokens to every session and 2,704 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
