Lifecycle Hooks Specification

Fires before the agent harness executes bash, read, write, or edit tool calls. If the command attempts to add a crate or npm package, jev-scout evaluates the package name against live registry registries. If the command attempts a destructive delete, jev-guard blocks it unless confidence >= 0.80.

  "PreToolUse": [
    {
      "matcher": "tool_name == 'Bash'",
      "command": "bash ~/.agents/jev-superpowers/hooks/pre-tool"
    }
  ]
}

Standard git pre-commit hook wired to git-jev. Evaluates the staged patch for architectural integrity, broken imports, and secret exfiltration before committing to git history.

#!/usr/bin/env bash
# .git/hooks/pre-commit
git-jev check || {
  echo "[BLOCKED] git-jev semantic gate rejected staged changes"
  exit 1
}

Intercepts the agent's turn completion or exit signal. limpet runs test assertions and compiler diagnostics. If any verification check fails, exit code 1 is returned with failure logs, forcing the agent to stay in context and resolve the issues.
