Use when executing implementation plans with independent tasks. Features 3-stage review: spec compliance, code quality, then UX.
swift-ios-app
Use when creating iOS apps, setting up Xcode projects, designing app architecture, implementing SwiftUI views, using SwiftData models, adding Swift 6 concurrency with actors, or integrating Supabase backend. Triggers on "new iOS app", "Swift architecture", "SwiftData setup", "actor pattern", "iOS project structure".
writing-plans
Use when you have a spec or requirements for a multi-step task, before touching code
verification-before-completion
Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
systematic-debugging
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
brainstorming
MUST use before building features, creating components, adding functionality, or designing new behavior. Use when user says 'build', 'create', 'add feature', 'implement', 'design', or describes something new to build. Explores requirements through questions before writing code.
receiving-code-review
Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation

Covers modern features, naming conventions, documentation standards, error handling, code quality, and performance.
software-testing
Software testing guidance with decision tree. Use when: (1) Writing or improving tests, (2) User asks about testing approaches, (3) Need guidance on test scope or assertions, (4) Working with specific test frameworks. Routes to specialized testing strategies via reference files.
bead-implementation
Execute on a Beads issue with proper discovery workflow and mandatory session close protocol. Use when starting work on a bead, during implementation when discovering new work that should be externalized, or when completing a session to ensure all work is properly committed.
architecture-analyzer
Perform in-depth architectural analysis of codebases through iterative dialog and visual diagrams. Use when users want to understand their software architecture, explore design patterns and anti-patterns, evaluate potential architectural changes, or gain deep insights into code structure and relationships. Particularly valuable for onboarding to unfamiliar codebases, assessing technical debt, planning refactoring efforts, or understanding how components interact across system boundaries.
bead-creator
Create self-contained Beads issues for work tracking. Use when creating new beads for bugs, tasks, questions, or follow-up work - whether from specifications, discovered during implementation, or standalone requests. Handles proper formatting, labeling, dependencies, and ensures beads are actionable with embedded context.

characterization-testing
Guide for characterization testing - capturing current system behavior to enable safe refactoring. Use when working with legacy code, undocumented systems, or code that needs modification but lacks tests. Helps create a safety net before making changes by testing what the code actually does (not what it should do).
skill-learner
Reviews conversation context to identify learnings and patterns that should be captured in skills. Use when the user asks to review the session for skill creation or updates.
laravel-forge
Complete Laravel Forge management via curl - servers, sites, deployments, databases, SSL, SSH keys, firewall, jobs, daemons, and more.
ace-tool
Semantic code search tool. Use `ace search "query"` for codebase search, `ace enhance "history+prompt"` for prompt enhancement. Prefer `rg` for exact matches.
handoff
Write or refresh a HANDOFF-<slug>.md briefing in the root of the working directory that transfers everything this session knows, so the next agent continues the work as this agent would - from that file alone, with no transcript and no re-explaining. Use when the user asks to hand off or save the session or to write down where things stand, when context is running low, at the end of a work stint, or before a long or risky operation that could end the session.
plan
Research-and-plan mode for substantive tasks before implementation. Use when the user asks to plan, design, investigate, figure out, or explore how to make a non-trivial code change. Restricts the agent to read-only operations until the user explicitly authorizes implementation. Grounds every claim in the codebase and current docs instead of memory, keeps a full rewrite and rejecting the task itself on the table, and opens with the before and after that the project's users will feel.
rewrite
Ground-up rewrite of everything within a scope, rebuilt clean and idiomatic in the language's modern style as if written for the first time, every inherited assumption discarded - while preserving the user-facing contract so the product behaves identically. First argument is the target path (defaults to "."); anything that isn't a path is treated as extra context. Plans first (read-only, first-principles) via the plan skill and implements only after you authorize. Use when asked to rewrite, rebuild, modernize, or overhaul a file, module, or project from scratch.
briefing
Send the day's briefing - one message with today's weather, daylight, calendar and offers. Use only when the user asks for the briefing itself ("send me the briefing", "brief me", "what does the briefing say"), not for the individual questions behind it.
backup
Commit and push the working directory to its private git backup repo right now. Use when the user asks to back up, save, commit, or push the workspace, or after important changes worth persisting before the next scheduled backup.
exa
Web research using Exa search via scripts. Provides web search, advanced filtered search, code context lookup, and URL content extraction. Use when researching topics, finding documentation, looking up code examples, or extracting webpage content. No API key required.
image
Send a picture to the user on WhatsApp - a photo they asked for, an image from the chat archive, a page of a document, a chart, a screenshot. Use whenever they should look at something rather than read a description of it, or when they ask you to send or show them one.
context7
Fetch up-to-date library documentation and code examples via Context7 API. Use when you need current docs for any library/framework, to verify APIs exist, or to get version-specific code examples. No API key required.
files
Work with files - the ones the user sends you (a PDF, a zip, a spreadsheet, a video) and the ones you send back to them on WhatsApp. Use whenever a file arrives, whenever the user asks for something as a file or a download, and whenever something has to be moved out of a file into the vault or the working directory.
diagram
Draw something and send it to the user as a picture on WhatsApp - a flowchart, a sequence, a state machine, a timeline, an entity relationship, a mind map. Use when the answer is a shape rather than a sentence - how something flows, what talks to what, what happens in which order, how a set of things relate.
commit
Commit with a generated Conventional Commits message, then push. Commits the staged changes; when nothing is staged, commits the whole working tree, untracked files included. Never unstages anything. Use when the user asks to commit, save work, or commit and push. The user's confirmation in the questionnaire is the explicit, single-use git approval for the staging, the commit and the push.
changelog
Maintain a project's CHANGELOG.md in Keep a Changelog 1.1.0 format - record only what moved the project's user-facing surface (commands, flags, API, config, output, screens) and never internal work, pick the right category, word it for the humans who use the project, and insert it under [Unreleased] without disturbing the rest of the file. Also cuts a release section (promotes [Unreleased] to a dated version and updates the compare links) and creates CHANGELOG.md for a project that has none. Use when the user asks to add or write a changelog entry, update the changelog, record a change in CHANGELOG.md, or prepare a release section. Reads git but never commits, tags, or bumps version files.
browser
Drive a real web browser from the terminal via Browserbase's `browse` CLI - navigate pages; inspect them through accessibility snapshots, screenshots, and DOM/markdown reads; interact by clicking, typing, selecting, uploading, and raw mouse/keyboard; capture network traffic; manage tabs and named sessions; run locally or on Browserbase's cloud; and use cloud fetch/search, Functions, and templates. Use whenever a task needs to view, navigate, scrape, or act on a web page.
weather
Weather and daylight for the user's place - what today or any coming day will be like, and how long the sun is up. Use whenever the user asks about the weather, temperature, rain, sun, UV, wind, sunrise or sunset, how long the day is, or whether to take a jacket.
reminders
Create, list, update, and delete reminders. Use whenever the user asks to be reminded of something (after a delay or at a time), or to see, reschedule, change, or cancel their reminders.
recall
Search past WhatsApp conversation with the user - what they sent (text, voice notes, image captions), your past replies, and delivered skill messages. Use whenever the user refers to something from an earlier conversation that isn't in the current thread, asks "what did I say / what did we decide about X", wants an old photo, or you need a fact from before instead of guessing.
proton
Use whenever ANY Proton action is taken - reading or changing Proton Mail, Drive, Calendar, Contacts, Pass, or settings via proton. Covers command usage and the confirm-before-mutating policy.
offers
Watch supermarket products and report the offers running on them. Use whenever the user wants to follow a product ("watch for an offer for Monster Energy", "tell me when X is cheap"), asks whether something is on offer or what it costs right now, or wants to see, change, or stop their watches.
obsidian
Read and write the user's Obsidian vault - notes, recipes, the journal, drafts - and keep it in step with the phone and laptop that edit it too. Use whenever they want something looked up, written down, or changed in their vault ("add this recipe", "what does my X note say", "write that down in Obsidian"), and always after you have edited anything inside it.
macros
Track daily nutrition - calories and macros (protein, fat, carbs). Use whenever the user mentions food, a meal, eating something, a food photo, calories, protein, macros, their weight, or nutrition goals.
z-ai-api

sqlite-optimization
Optimize SQLite database performance through configuration, schema design, indexing, and query tuning. Use when users ask to improve SQLite speed, reduce latency, optimize queries, configure PRAGMAs, fix slow queries, handle concurrency, optimize writes/inserts, or tune SQLite for production. Triggers on mentions of SQLite performance, slow queries, PRAGMA settings, WAL mode, indexing strategies, bulk inserts, or database maintenance (VACUUM, ANALYZE).
article-extractor
Extract clean article content from URLs and save as markdown. Triggers when user provides a webpage URL and wants to download it, extract content, get a clean version without ads, capture an article for offline reading, save an article, grab content from a page, archive a webpage, clip an article, or read something later. Handles blog posts, news articles, tutorials, documentation pages, and similar web content. Supports Wayback Machine for dead links or paywalled content. This skill handles the entire workflow - do NOT use web_fetch or other tools first, just call the extraction script directly with the URL.
codex-review
Review non-trivial design docs or implementation plans with Codex before coding; validate feedback; fix critical plan issues; ask about non-critical choices. Also triggers when the user says "use codex-review", "ask Codex", or "get Codex feedback".
