AfterTool — Hook for Claude Code by King-A23/agent-reflectmem

AfterTool

AfterTool is a hook for Claude Code from King-A23/agent-reflectmem. Its token cost is not measured, scanned A, a copy of BeforeTool, MIT.

An automatic follow-up action that runs after a shell command used by an agent. It invokes a reflection-memory script after each matching command.

In plain words

What is it for?: Use it when you want shell-command runs to trigger the configured reflection and memory handling automatically.
Why use it?: It records or processes follow-up information without requiring the agent to remember a separate step after running a command.

Written for Claude Code: a Claude Code hooks.json. Also seen: mentions Gemini CLI.

One of 4 entries in hooks.json upstream. Installing this one merges just its entry into your config; the other 3 are separate, each on its own page.

Good fit Use it when you want shell-command runs to trigger the configured reflection and memory handling automatically.

Security

Grade A, and why

AfterTool 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

92% identical to BeforeTool — 4 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.
