Document the pitfalls encountered or good practices discovered during this work into searchable learning documents, which can be accessed by both AI and humans when similar tasks arise in the future. Two tracks: The pitfall track records experiences where "things should have worked but didn't" — including bugs, configuration traps, environment issues, and integration failures; The knowledge track records findings that "should be the default approach going forward" — including best practices, workflow improvements, and reusable patterns. Trigger scenarios: Proactively prompt at the end of feature-acceptance or issue-fix workflows, or when the user mentions phrases like "document knowledge", "learning", "document learnings", or "record this experience". Spec documents record what was done, while learning documents record what pitfalls were encountered / what was learned — they complement each other and are not interchangeable.
Generate reference documentation entry by entry for the public surface of a library (components, functions, commands, etc.), with manifest tracking, supporting both single-entry and batch modes. Fundamental difference from guidedoc: guidedoc teaches you how to use something, while libdoc tells you what each part looks like; guidedoc's information sources are solution docs + user knowledge, while libdoc's information source is the source code itself. Trigger scenarios: When the user says "write API documentation", "component documentation", "libdoc", "write documentation for each component", or when new public library interfaces are discovered after feature-acceptance.
Drive a PR to mergeable state — check CodeRabbit and reviewer comments, address valid ones, reply and resolve invalid ones, fix CI failures (even pre-existing ones from main), push fixes, then loop every 4.5 minutes until two consecutive clean checks. Use after opening a PR when you want it babysitted to green.
微信公众号文章抓取与导出。自动处理 mp.weixin.qq.com 的登录态获取与续期， 支持按公众号搜索、抓取文章列表与正文、按日期窗口导出 Markdown / JSON / CSV。 Trigger when the user wants to crawl a WeChat public account, export recent articles, or 提到 "wcx"、"微信公众号"、"公众号文章"、"mp.weixin"、"抓公众号"、 "crawl wechat official account"、"wxmp"、"最近十天的文章"。
Implements keyboard, directional, and scene-level focus behavior across SwiftUI and UIKit. Use when managing @FocusState, defaultFocus, focused values, focusable interactions, focus sections, tvOS geometric focus model and Siri Remote navigation, watchOS Digital Crown focus, visionOS gaze/hover and RealityKit InputTargetComponent, macOS key view loop and Full Keyboard Access, focus restoration after presentation changes, custom focus routing with UIFocusGuide, or debugging focus with UIFocusDebugger.
Format values for display using the FormatStyle protocol and its concrete types. Use when formatting numbers (integers, floating-point, decimals), currencies, percentages, dates, date ranges, relative dates, durations (Duration.TimeFormatStyle, Duration.UnitsFormatStyle), measurements, person names (PersonNameComponents.FormatStyle), byte counts (ByteCountFormatStyle), lists (ListFormatStyle), and URLs (URL.FormatStyle). Also covers creating custom FormatStyle conformances and replacing legacy Formatter subclasses. FormatStyle is available iOS 15+; Duration styles require iOS 16+.
Build and test iOS apps on simulator using XcodeBuildMCP. Use after making iOS code changes, before creating a PR, or when verifying app behavior and checking for crashes on simulator.
Summarize recent compound-engineering plugin releases, or answer a specific question about a past release with a version citation. Use when the user types `/ce-release-notes` or asks "what changed in compound-engineering recently?" or "what happened to `<skill-name>`?".
Clean up local branches whose remote tracking branch is gone. Use when the user says "clean up branches", "delete gone branches", "prune local branches", "clean gone", or wants to remove stale local branches that no longer exist on the remote. Also handles removing associated worktrees for branches that have them.
Create, share, view, comment on, edit, and run human-in-the-loop review loops over markdown documents via Proof, the collaborative markdown editor at proofeditor.ai ("Proof editor"). Use when the user wants to render or view a local markdown file in Proof, share markdown to get a URL, iterate collaboratively on a Proof doc, comment on or suggest edits in Proof, HITL a spec/plan/draft for human review, sync a Proof doc back to local, or work from a proofeditor.ai URL. Trigger on phrases like "view this in proof", "share to proof", "iterate with proof", or "HITL this doc", and on ce-brainstorm / ce-ideate / ce-plan handoffs for human review. Also match clear requests for a rendered/shared markdown review surface even if the user does not name Proof. Do not trigger on "proof" meaning evidence, math/logic proof, burden of proof, proof-of-concept, or bare "proofread this" requests where inline text review is expected.
Discover session files for a repo across Claude Code, Codex, and Cursor, and extract session metadata (timestamps, branch, cwd, size, platform). Invoked by session-research agents — not intended for direct user queries.
Use when implementing ANY Apple Intelligence or on-device AI feature. Covers Foundation Models, @Generable, LanguageModelSession, structured output, Tool protocol, iOS 26 AI integration.
