NemoNotch: Settings file for Claude Code

.claude/settings.json

NemoNotch is a settings file for Claude Code from GaoZimeng0425/NemoNotch. Its token cost is not measured, scanned A, original, MIT.

An agent setting with a PostToolUse hook, meaning it runs after a tool finishes. After a Swift file is written or edited, it runs SwiftFormat, a formatter for Swift source code.

In plain words
What is it for?
Use it in projects that contain Swift files and have SwiftFormat installed. It applies formatting after write and edit operations.
Why use it?
It keeps changed Swift files formatted automatically instead of relying on a separate manual formatting step.

Settings file for Claude Code

Written for Claude Code: PostToolUse hook event.

This is GaoZimeng0425/NemoNotch's own configuration. It tells Claude Code how to work on NemoNotch 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 NemoNotch 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.

Security

Grade A, and why

NemoNotch 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 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

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.
