agentsmith-cli: Skill for Claude Code

.github/skills/hook-lifecycle-execution/SKILL.md

hook-lifecycle-execution is a skill for Claude Code, Codex from shyamsridhar123/agentsmith-cli. It costs 21 tokens per session (191 once invoked), scanned A, original, MIT.

A runner for YAML-defined lifecycle hooks, which are commands triggered by project events such as before a commit or after generation. Hooks can have conditions and time limits.

In plain words
What is it for?
Use it to discover and execute event-specific hooks under .github/hooks, evaluate file or command conditions, and collect each hook's result.
Why use it?
It provides a consistent way to run project actions and stop or report failures when conditions are not met or commands take too long.

Written for no agent in particular: nothing here depends on one.

This is shyamsridhar123/agentsmith-cli's own configuration. It tells Claude Code and Codex how to work on agentsmith-cli 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 agentsmith-cli 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

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 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.

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');

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.
