app-trading-engine

A Claude Code settings file that runs checks around planning, task completion, and shell commands.

In plain words
What is it for?
It enforces design and plan reviews before leaving planning mode, checks review and test gates before completion, and asks before merging a GitHub pull request.
Why use it?
It helps prevent plans or tasks from being marked complete before required reviews and tests have been checked.

Grade A, and why

app-trading-engine 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 2d 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.
