chainlink: Hook for Claude Code

.claude/settings.json

UserPromptSubmit is a hook for Claude Code from dollspace-gay/chainlink. Its token cost is not measured, scanned A, original, MIT.

An automatic check that runs when you submit a prompt, before the coding agent receives it. It runs a project script named prompt-guard.py from the nearest .claude folder.

In plain words
What is it for?
Use it for prompt validation or other checks that must happen before the agent sees a request. The exact behavior depends on prompt-guard.py.
Why use it?
It can inspect or reject prompts before work begins, helping apply project-specific rules at the start of each request.

Hook for Claude Code

Written for Claude Code: UserPromptSubmit hook event.

This is dollspace-gay/chainlink's own configuration. It tells Claude Code how to work on chainlink 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 chainlink configures →

One of 5 entries in settings.json upstream. Installing this one merges just its entry into your config; the other 4 are separate, each on its own page.

Security

Grade A, and why

UserPromptSubmit 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 8d 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.
