PostHogSkill

qa-frontend

PostHog/posthog/.agents/skills/qa-frontend/SKILL.md

Internal PostHog developer frontend/browser QA skill. Use only when a PostHog developer explicitly asks to run frontend QA, browser-test a PR, verify a UI flow against the local PostHog stack, use qa-frontend, or QA current frontend changes with browser/runtime evidence, or to make a feature reel (see reel mode below). Do not use for generic code review, PR review, "check my changes", CI debugging, or security audit; use qa-team, debugging-ci-failures, or security-audit instead. QA runs in PR mode or local mode, plans adaptive browser and visual checks, drives browser MCP/tooling such as Playwright MCP or Chrome DevTools MCP, captures evidence, and applies only approved/narrow fixes. Reel mode makes a feature reel instead: a short, sharp animated WebP of one UI flow for a PR description. Use it when asked for a reel, GIF, or animated demo, or when writing-pr-descriptions calls for a reel: a new action and its effect that one screenshot cannot show.

langflow-aiSkill

langflow-ai/langflow/.agents/skills/frontend-i18n/SKILL.md

Add, change, or review user-facing text in the Langflow frontend using the i18n system (i18next / react-i18next).

Every user-facing string must go through the translation system and every new key must exist in ALL locale files. Do NOT use for backend strings, log messages, or code identifiers.
