opus-fable-playbook: Hook for Claude Code

.claude/settings.json

Stop is a hook for Claude Code from rennf93/opus-fable-playbook. Its token cost is not measured, scanned A, original, MIT.

A stop hook that runs a shell script when the coding agent finishes a response.

In plain words
What is it for?
Use it to trigger stop-gate.sh at the end of an agent response and enforce whatever checks that script defines.
Why use it?
It provides a final automated check before the agent stops, based on the included stop-gate script.

Hook for Claude Code

Written for Claude Code: installed under .claude/.

This is rennf93/opus-fable-playbook's own configuration. It tells Claude Code how to work on opus-fable-playbook 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 opus-fable-playbook configures →

Part of the fable-mode plugin — 3 skills, 2 commands, 1 agent, 10 hooks shipped together

One of 10 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 9 are separate, each on its own page.

Security

Grade A, and why

Stop scanned grade A with 0 findings 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 8d ago.

A static scan of the commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.
