Optimize Core Web Vitals (LCP, INP, CLS) for better page experience and search ranking. Use when asked to "improve Core Web Vitals", "fix LCP", "reduce CLS", "optimize INP", "page experience optimization", or "fix layout shifts".

Add a model or provider mapping to the catalogue, or verify one that was already written — pricing, capability and reasoning metadata, scoped e2e, and playground options for image/video models. Use when the user asks to add a named model on a provider, create a provider mapping, check model pricing, verify a model, or change packages/models/src/models.

Write and validate an LLM Gateway marketing blog post in the repository's current house style, including structured frontmatter and a gpt-image-2 OpenGraph image. Use when the user says "blog", "blog post", "write a blog post", "draft a blog", "add a blog post", "publish a blog", or "write an article" for the marketing site. For shipped-feature release notes use the `changelog` skill instead.

Write a new LLM Gateway changelog entry. Use when the user says "changelog", "changelog entry", "write a changelog", "add a changelog", "announce this feature", or asks to document a shipped feature for the public changelog. Produces the dated markdown file under apps/ui/src/content/changelog plus a gpt-image-2 prompt for the OpenGraph image.

Write a new LLM Gateway docs Knowledge base page under apps/docs/content/learn with light and dark dashboard screenshots. Use when the user asks for a knowledge base page, KB page, learn page, or documentation for a dashboard or playground page with screenshots.

Generate, review, edit, apply, or resolve conflicts for Drizzle database migrations in this repo. Use when changing packages/db/src/schema.ts, running pnpm migrations or pnpm migrate, touching packages/db/migrations, reviewing migration diffs, or handling migration merge conflicts.

Create, update, illustrate, and hand off pull requests in this repo. Use when opening a PR, pushing a branch for review, writing or revising a PR title/description, embedding a screenshot or image in a PR body, triggering e2e CI on a PR, or whenever the user mentions "PR", "pull request", "open a PR", "update the PR", or "attach a screenshot to the PR".

Create, update, and audit repository-local agent skills against the current LLM Gateway codebase. Use when adding or editing files under .agents/skills or .claude/skills, reviewing a skill for stale instructions, or checking that skill paths, commands, cross-references, and workflows actually exist.

Build, launch, and drive the LLM Gateway stack in an isolated worktree environment to verify API, gateway, dashboard, playground, or screenshot changes. Use when locally reproducing a change, launching services on offset ports, taking seeded-data screenshots, or checking a workflow end to end.
