PostToolUse

PostToolUse is a hook for Claude Code from parcadei/Continuous-Claude-v3. Its token cost is not measured, scanned A, a copy of PreToolUse, MIT.

A set of automatic checks that run after coding tools finish editing files or running commands. The checks include TypeScript preparation, compilation, diagnostics, change notifications, handoff indexing, and tool-use tracking.

In plain words
What is it for?
It is for running post-edit validation and project tracking after Edit, Write, MultiEdit, or Bash tool calls.
Why use it?
It provides feedback immediately after changes, helping reveal compile errors, diagnostics, and other issues before they are missed.

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.

Origin

This is a copy

88% identical to PreToolUse — 62 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.
