SubagentStop — Hook for Claude Code by keefar/ticket-flow

SubagentStop

SubagentStop is a hook for Claude Code from keefar/ticket-flow. Its token cost is not measured, scanned A, a copy of SubagentStop, MIT.

An automatic hook that runs a verdict-checking script whenever a subagent finishes. A subagent is a separate coding-agent worker handling part of a task.

In plain words

What is it for?: Use it in Claude Code hook configuration to run verdict-gate.sh after every subagent completion.
Why use it?: It provides a completion check at the point where delegated work ends, helping the workflow evaluate the subagent’s result.

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the ticket-flow plugin — 12 skills, 2 hooks shipped together

One of 2 entries in hooks.json upstream. Installing this one merges just its entry into your config; the other 1 are separate, each on its own page.

Security

Grade A, and why

SubagentStop 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 2mo 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

83% identical to SubagentStop — 3 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.
