Thermite: Settings file for Claude Code

.claude/settings.json

Thermite is a settings file for Claude Code from Corvidae-Coding-Projects/Thermite. Its token cost is not measured, scanned A, original, MIT.

A settings file that defines commands run at key moments during an agent session, such as when a session starts, a prompt is submitted, or a file is read or changed.

In plain words
What is it for?
Use it to configure startup dependency checks, prompt guards, post-edit checks, specification checks, and session heartbeats.
Why use it?
It automates project checks and startup tasks so they do not have to be run manually each time.

Settings file for Claude Code

Written for Claude Code: PostToolUse hook event.

This is Corvidae-Coding-Projects/Thermite's own configuration. It tells Claude Code how to work on Thermite 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 Thermite 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

Thermite 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 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.

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.
