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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00112 | $0.02704 |
| Opus 5 | $0.00056 | $0.01352 |
| Sonnet 5 | $0.00022 | $0.00541 |
| Haiku 4.5 | $0.00011 | $0.00270 |
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.
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.

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
DATAcontient la clé"error"→ afficher l'erreur et s'arrêter. - Si
has_hooksestfalse→ écrire[]dans/tmp/hookstack-hooks-new.jsonet 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 (cléhooks).claude/hooks.json/hooks.json— config hooks seule à la racinehooks/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
DATAcontient la clé"error"→ afficher l'erreur et s'arrêter. DATAcontient :{ source_type, url, title, content, existing_slugs }.contentest 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.
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.
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.
- 5d ago First seen · 195 lines · 112 tokens per session scan A 38a36de8295a
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.
