PostToolUse

PostToolUse is a hook for coding agents from AgriciDaniel/claude-repurpose. Its token cost is not measured, scanned A, original, MIT.

A post-tool hook that runs a small shell check after a Write tool finishes. A hook is an automatic action attached to a tool event.

In plain words
What is it for?
It is for running the included check after Write operations, including when creating Markdown files.
Why use it?
It provides an automatic check after files are written, without requiring a separate manual command.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo
git clone --depth 1 https://github.com/AgriciDaniel/claude-repurpose

Or install claude-repurpose, the plugin that ships this one along with the rest of its 21 skills, 6 agents, 1 hook.

Security

Grade A, and why

PostToolUse 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 5d 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.
