A collection of three software-design skills: one for feature specifications, one for API design, and one for database schema design. They are intended to fit proposed changes to the codebase's existing patterns and query needs.

Use it when planning a feature, reviewing or designing API endpoints, or designing database tables and safe changes to existing production data.

It gives a team a shared place to think through feature scope, service endpoints, and data changes before implementation. This can expose compatibility and migration issues early.

Security

Grade A, and why

craft-stack 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.
