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 | $0.00021 | $0.00191 |
| Opus 5 | $0.00010 | $0.00096 |
| Sonnet 5 | $0.00004 | $0.00038 |
| Haiku 4.5 | $0.00002 | $0.00019 |
Grade A, and why
hook-lifecycle-execution 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 4d 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.

Expected in a hook, worth knowing in a rule or an instructions file.
- execSync command execution with timeout What it actually says
Hook Lifecycle Execution
Load and execute YAML-defined lifecycle hooks with optional conditions and controlled timeouts.
When to Use
Use this skill when:
- Working with code in
src/hooks/index.ts/ - User mentions "hooks"
- User mentions "pre-commit"
- User mentions "post-generate"
- User mentions "condition"
- User mentions "timeout"
Patterns
- event-scoped hook discovery under .github/hooks
- execSync command execution with timeout
- file/command condition evaluation
- verbose output and early failure stop
- per-hook success/error aggregation
Examples
const runner = new HookRunner(rootPath, verbose); await runner.execute('post-generate');

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.

hook-lifecycle-execution is a skill published in the GitHub repository shyamsridhar123/agentsmith-cli (16 stars, last pushed 6d ago), licensed MIT. It adds 21 tokens to every session and 191 once invoked, about $0.0001 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 2026-08-30.
