Hook for Claude Code

Written for Claude Code: ${CLAUDE_PROJECT_DIR} variable.

This is moq-dev/moq's own configuration. It tells Claude Code how to work on moq 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 moq configures →

One of 2 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 1 are separate, each on its own page.

About the project

moq-dev/moq is an implementation of Media over QUIC, a protocol for delivering live media and other real-time data over QUIC with WebTransport, WebCodecs, and WebAudio. It is intended for live streaming and other applications that need low latency and large-scale fan-out, with Rust and TypeScript libraries. The catalogue add-ons teach coding agents how to build with MoQ.

Security

Grade A, and why

SessionStart 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 7d 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

64% identical to SessionStart — 6 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.

Changes

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.
