ip-intelligence: Hook for Claude Code

.claude/settings.json

PreToolUse is a hook for Claude Code from ard1102/ip-intelligence. Its token cost is not measured, scanned A, original, MIT.

A set of automatic checks that runs before certain agent actions, such as searching code or editing Python files. It can redirect searches to a codebase-memory tool and report whether a matching test exists before Python code is changed.

In plain words
What is it for?
Use it to add pre-action controls for code searches and Python edits, including test-presence checks and inline shell validation.
Why use it?
It enforces project-specific safeguards at the point where a tool is used. These checks can discourage unsupported search methods and reveal when production Python code is being changed without nearby tests.

Hook for Claude Code

Written for Claude Code: PreToolUse hook event.

This is ard1102/ip-intelligence's own configuration. It tells Claude Code how to work on ip-intelligence 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 ip-intelligence configures →

One of 3 entries in settings.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 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.

This page is one entry in a file that holds 3. Installing the file brings all of them; each is measured and scanned on its own page.

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.
