Profiles

Ready-made CPO policy sets. Guardrails block what an agent must never do; quality and stack profiles hold generated code to your conventions. Set a profile by its id.

• Anti-AI Patterns Writing

  Copy in HTML, Vue, Svelte, Astro, TSX and JSX reads as written for its readers. Phrases, structures and characters associated with templated (often AI-generated) prose warn with the rule ID and a repair; explicit contracts block. Style suggestions, never authorship verdicts.

• Next.js 16

  Next.js 16.4 apps (App Router, Pages Router, both) without pre-16 APIs, with explicit server/client and cache boundaries, package-manager-owned dependencies and evidenced completion. Rule IDs B, T, V, S, R, C, X, A, U, Q; NEED TO blocks.

• Tailwind CSS v4

  Strict utility-first Tailwind CSS v4 frontends. Blocks introduced v3 patterns (V3-01–V3-15) and plain-CSS styling outside approved boundaries (CSS-01–CSS-06); warns on advisories (Q); missing evidence never blocks.
