From the project's own README (excerpt, reproduced for discovery under its MIT license):
Agent Skills
Production-grade engineering skills for AI coding agents.
Skills encode the workflows, quality gates, and best practices that senior engineers use when building software. These ones are packaged so AI agents follow them consistently across every phase of development.

Commands
9 slash commands that map to the development lifecycle. Each one activates the right skills automatically.
What you're doing Command Key principle ------------------- --------- --------------- Define what to build /spec Spec before code Plan how to build it /plan Small, atomic tasks Build incrementally /build One slice at a time Prove it works /test Tests are proof Set the quality bar /constraints Decide it once, enforce it everywhere Review before merge /review Improve code health Audit web performance /webperf Measure before you optimize Simplify the code /code-simplify Clarity over cleverness Ship to production /ship Faster is safer
Want fewer manual steps once the spec exists? /build auto generates the plan and implements every task in a single approved pass — you approve the plan once, then it runs autonomously. It removes the human stepping between tasks, not the verification: every task is still test-driven and committed individually, and it pauses on failures or risky steps.
Skills also activate automatically based on what you're doing — designing an API triggers api-and-interface-design, building UI triggers frontend-ui-engineering, and so on.

03Community
No endorsements yetNo verified confirmations yet — be the first.
Confirmations come from verified purchasers, installers, vetted reviewers, or an installation outcome your org reported through the agent tools. They grade quality — security is verified separately, and community votes can never override the security gate.

04Trust Passport
Full passport →0/0 automated components pass. An automated score is never a security guarantee.
This listing is unclaimed, so publisher identity cannot be verified and it stays below the “verified” tier by design — that is a statement about the listing, not about the project’s quality. Our automated scans still ran; a maintainer who claims it unlocks identity verification.
