SpecRoute: Hook for Claude Code

.claude/hooks/hooks.json

PreToolUse is a hook for Claude Code from Enovatr-Labs/SpecRoute. Its token cost is not measured, scanned A, original, Apache-2.0.

A pre-tool hook that runs a Bash sanitization script before the agent uses a Bash tool.

In plain words
What is it for?
Use it to run `.claude/hooks/pre-bash-sanitize.sh` before Bash calls, with a 60-second limit and a status message.
Why use it?
It adds a sanitization check before Bash commands run, so the check does not have to be started manually.

Hook for Claude Code

Written for Claude Code: ${CLAUDE_PROJECT_DIR variable.

This is Enovatr-Labs/SpecRoute's own configuration. It tells Claude Code how to work on SpecRoute itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything SpecRoute configures →

One of 3 entries in hooks.json upstream. Installing this one merges just its entry into your config; the other 2 are separate, each on its own page.

Security

Grade A, and why

PreToolUse 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 9d 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.
