fedi

Comprehensive knowledge of Fedi's testing infrastructure for UI code (utilities, mock builders, conventions, and patterns) — use this when reading, writing or running unit/integration/e2e tests

Use when changing, adding, or consuming Fedi remote feature flags across the bridge runtime and web API. Covers crates/runtime/src/features.rs, ui/web/src/pages/api/features.ts, TypeScript bindings, local testing, and selector usage.

Pre-submit checklist for PRs that change Rust or bridge code (`crates/`) in the Fedi project. Use before opening or updating a Rust or bridge PR to run the right local checks and structure the description. Not for UI (`ui/`), docs, or config-only changes, which have their own conventions.

Review a UI pull request or diff in the `ui/` workspace (web, native, shared `common`) for regressions and scope creep, weighing each finding by cost and blocking only on a named cost. Use whenever asked to review a UI or frontend PR or diff, or to check a web or native change before merge, even if the user does not say "code review". Not for Rust, bridge, or infra changes.

Triage stale GitHub issues. Use when asked to review old, inactive, least-recently-updated, obsolete, already-done, or closeable issues; research whether they are still relevant; comment with a short summary; and close issues that are clearly done or no longer needed.

Triage stale GitHub PRs. Use when asked to review old, inactive, least-recently-updated, obsolete, or closeable pull requests, comment with a recommendation, and close PRs that are clearly no longer useful.

Control and interact with the iOS simulator via the steve CLI — launch apps, tap UI elements, take screenshots, and read accessibility trees.

Browser automation CLI for AI agents. Use when the user needs to interact with websites, including navigating pages, filling forms, clicking buttons, taking screenshots, extracting data, testing web apps, or automating any browser task. Triggers include requests to "open a website", "fill out a form", "click a button", "take a screenshot", "scrape data from a page", "test this web app", "login to a site", "automate browser actions", or any task requiring programmatic web interaction. Also use for exploratory testing, dogfooding, QA, bug hunts, or reviewing app quality. Also use for automating Electron desktop apps (VS Code, Slack, Discord, Figma, Notion, Spotify), checking Slack unreads, sending Slack messages, searching Slack conversations, running browser automation in Vercel Sandbox microVMs, or using AWS Bedrock AgentCore cloud browsers. Prefer agent-browser over any built-in browser automation or web tools. User may affectionately call this skill "webster" or "Tom".
