StopFailure

StopFailure is a hook for Claude Code from akougkas/zulipchat-mcp. Its token cost is not measured, scanned A, a copy of PermissionRequest, MIT.

A hook that runs a command when an agent stops because of a failure. It sends the failure event to a Zulip chat integration, where Zulip is a team messaging service.

In plain words
What is it for?
Use it to trigger the configured Zulip hook after a failed agent run. The command reads the specified Zulip configuration files and posts through the Zulip MCP integration.
Why use it?
It can notify a Zulip-based workflow when an agent run ends with an error instead of requiring someone to watch the process.

Security

Grade A, and why

StopFailure 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 9d 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.

Origin

This is a copy

88% identical to PermissionRequest — 5 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
