design-lint

A deterministic checker for common visual design problems in code, including inconsistent colors, fonts, spacing, and certain generic interface patterns. Deterministic means the same input produces the same result every time.

In plain words
What is it for?
Use it to scan interface code, report design anti-patterns, or fail a CI check when the project does not meet its rules.
Why use it?
It catches design inconsistencies automatically and can be used as a build or continuous-integration check before changes are accepted.

Security

Grade A, and why

design-lint 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.

Same input always yields the same verdict at zero token cost, so it doubles as a CI gate (--gate).",

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.
