PostToolUse

PostToolUse is a hook for coding agents from volkangunay/agentclaim. Its token cost is not measured, scanned A, original, MIT.

A post-tool hook configuration that runs an agent-claim script after common file and shell operations finish. A hook is an automatic action connected to a tool event.

In plain words
What is it for?
Use it in Claude Code to run agentclaim.js after Read, Write, Edit, MultiEdit, NotebookEdit, and Bash calls. It applies to both file operations and shell commands.
Why use it?
It records or processes activity after tools such as reading, writing, editing, or running shell commands complete. The input names the script but does not explain its detailed behavior.

Hook

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 agentclaim plugin — 4 hooks, 1 MCP server shipped together

One of 4 entries in hooks.json — they are configured in one file and arrive together.

Getting it into your agent

This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Claude Code
/plugin marketplace add volkangunay/agentclaim
Claude Code
/plugin install agentclaim

Or install agentclaim, the plugin that ships this one along with the rest of its 4 hooks, 1 MCP server.

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 4d 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.
