PostToolUse

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

A post-tool hook that runs a Python reminder script after Bash commands finish.

In plain words
What is it for?
It is for running an automatic reminder after each completed Bash tool call.
Why use it?
It helps remind you about a follow-up step after shell work, such as checking whether changes were committed.

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 claude-reflect plugin — 1 skill, 4 commands, 4 hooks shipped together

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

About the project

claude-reflect is a self-learning system for Claude Code that records corrections, positive feedback, preferences, and recurring workflows as persistent instructions or reusable skills. It helps Claude Code users retain lessons across sessions and improve repeated tasks, with catalogue add-ons providing its hooks, commands, instructions, plugin, and skill.

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 6d 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.
