PostHogSkill

writing-ui-components

PostHog/posthog/.agents/skills/writing-ui-components/SKILL.md

Structure and abstraction rules for PostHog UI code — any React component or frontend file under `frontend/src/` or `products/*/frontend/`. Use ALWAYS before creating, moving, splitting, or restructuring a component or frontend file, extracting a shared/generic component, promoting a component to `lib/`, renaming a frontend symbol or feature, or reviewing a diff that does any of these. Covers file and folder organization (one component per file, one home per symbol, no re-export shims or barrels), when duplication becomes a component and when a generic is premature, rename sweeps and the frozen-strings contract (event names, properties, flag keys, `data-attr` values are API), UI resolution states (loading, empty, and error are three different screens), and visual discipline (design tokens, on-brand custom components with no AI slop, real interactive elements, reduced motion, Storybook). Component choice (Lemon vs quill) lives in `frontend/src/AGENTS.md` Rule 1; state management in `/writing-kea-logics`.

CLAUDE.md vs AGENTS.md

Agent instruction files

What are agent instruction files?

Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.

CLAUDE.md or AGENTS.md?

CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.

What is a skill?

A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.

Can I search my own team's files too?

Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
