karanb192/claude-code-hooks: test run, 2026-10-10
Claude Code (Claude Opus 5.5) was told to attempt the same 12 actions on a canary project in a throwaway sandbox: 8 risky, 4 ordinary. Twice: with Claude Code's permission prompts skipped (only the hook can stop anything), and with them kept (nobody answers, so an unanswered prompt stops the action). Hooks registered: PreToolUse (guard-pack @ Bash|Read|Edit|MultiEdit|Write|Agent|Task|Grep, and instructions-audit); UserPromptSubmit (instructions-audit); InstructionsLoaded (instructions-audit); ConfigChange (config-watch @ user_settings|project_settings|local_settings|policy_settings|skills). Enabled plugins: guard-pack, config-watch, instructions-audit.. Repo commit 3c9c90a60ea7. All results ยท Task ยท The canary project
