Public Skills
audit
by howells
Comprehensive codebase audit with specialized reviewers. Generates actionable reports. Use when asked to "audit the codebase", "review code quality", "check for issues", "security review", or "performance audit". Accepts path scope like "apps/web". Reviewers run in batches of 2 by default to avoid resource exhaustion. Use --parallel to run all reviewers simultaneously (resource-intensive). Use --diff to scope audit to files changed vs main branch (or specify base: --diff develop). Use --docs for a focused JSDoc/documentation coverage audit. Use --copy for a focused UX writing/copy quality audit.
ideate
by howells
Turn ideas into validated designs through collaborative dialogue with built-in expert review. Use when asked to "design a feature", "plan an approach", "think through implementation", or when starting new work that needs architectural thinking before coding.
verify
by howells
Run sequential verification checks on the current codebase. Build, typecheck, lint, tests, debug log audit, and git status. Stops on critical failures. Supports modes: quick, full, pre-commit, pre-pr.
detail
by howells
Internal skill for creating implementation plans. Invoked by /arc:implement, not directly. Creates detailed plans with exact file paths, test code, and TDD cycles.
implement
by howells
Plan and execute feature implementation with TDD and continuous quality checks. Use when asked to "implement this", "build this feature", "execute the plan", or after /arc:ideate has created a design doc. Creates implementation plan if needed, then executes task-by-task with build agents.
legal
by howells
Generate Privacy Policy, Terms of Service, and Cookie Policy pages. Use when setting up legal pages for a new project, when asked to "create privacy policy", "add terms of service", "generate legal pages", or when /arc:letsgo identifies missing legal documents.
ai
by howells
AI SDK guidance for building AI-powered features. Loads correct patterns, warns about deprecated APIs, and guides through chat UIs, agents, structured output, and streaming. Use when building AI features, debugging AI SDK errors, or before implementing any AI work.
document
by howells
Generate documentation for your codebase — reference docs for a file, feature guides, or a full documentation site. Use when asked to "document this", "generate docs", "write documentation", "create API reference", or when you need thorough documentation for a module, feature, or entire project. Framework-aware: detects Fumadocs, Nextra, Docusaurus, etc. and generates in the right format.
build
by howells
Build small-to-medium features with lightweight planning and full agent orchestration. Use for "build this component", "add this feature", "create this utility" — work that doesn't need full ideate/implement but still deserves proper planning and quality gates.
review
by howells
Run expert review on a plan with parallel reviewer agents. Presents findings as Socratic questions. Use when asked to "review the plan", "get feedback on the design", "check this approach", or before implementation to validate architectural decisions. Optional argument: reviewer name (e.g., /arc:review daniel-product-engineer to use a specific reviewer)
deps
by howells
Dependency audit, alternative discovery, and batch upgrades with test verification. Use when asked to "check dependencies", "audit packages", "update dependencies", "find outdated packages", or "check for CVEs". Generates a prioritized report, then optionally walks through batch upgrades with rollback on failure.
design
by howells
Create distinctive, non-generic UI designs with aesthetic direction and ASCII wireframes. Use when asked to "design the UI", "create a layout", "wireframe this", or when building UI that should be memorable rather than generic. Avoids AI slop patterns.
rules
by howells
Apply Arc's coding rules to the current project. Copies rules to .ruler/ directory. Use when asked to "set up coding rules", "apply standards", "configure rules", or when starting a project that should follow Arc's conventions.
testing
by howells
Comprehensive testing strategy. Creates test plans covering unit, integration, and E2E. Uses specialist agents for each test type. Supports vitest and Playwright with auth testing guidance for Clerk and WorkOS.
responsive
by howells
Audit and fix responsive/mobile issues across every page of a project, using Chrome MCP screenshots at two breakpoints (375px mobile, 1440px desktop). Design-aware: reads existing design docs to preserve aesthetic intent, not just "make it fit." Use when asked to "make it responsive", "fix mobile", "responsive audit", or after building a desktop-first UI that needs mobile adaptation.
go
by howells
The main entry point. Understands your codebase and routes to the right workflow. Use when starting a session, saying "let's work on something", or unsure which Arc command to use. Gathers context and asks what you want to do.
letsgo
by howells
Production readiness checklist covering domains, SEO, security, and deployment. Use when asked to "ship it", "deploy to production", "go live", "launch", or when preparing a project for production deployment.
commit
by howells
Smart commit and push with auto-splitting across domains. Creates atomic commits. Use when asked to "commit", "push changes", "save my work", or after completing implementation work. Automatically groups changes into logical commits.
suggest
by howells
Opinionated recommendations for what to work on next based on Linear issues, tasks, and codebase. Use when asked "what should I work on", "what's next", "suggest priorities", or when starting a session and unsure where to begin.
prune-agents
by howells
Kill orphaned Claude subagent processes that didn't exit cleanly. Use when asked to "prune agents", "clean up agents", "kill orphaned processes", or when subagents accumulate from Task tool usage.
vision
by howells
Create or review a high-level vision document capturing project goals and purpose. Use when asked to "define the vision", "what is this project", "set goals", or when starting a new project that needs clarity on purpose and direction.
naming
by howells
Generate and validate project names. Reads codebase context, produces candidates using tech naming strategies, and checks domain + GitHub availability. Use when naming a new project, renaming, or validating an existing name.
tidy
by howells
Clean up completed plans in docs/plans/. Archives or deletes finished plans. Use when asked to "clean up plans", "tidy the docs", "archive old plans", or after completing implementation to remove stale planning documents.
seo
by howells
Deep SEO audit for web projects. Analyzes codebase for crawlability, indexability, on-page SEO, structured data, social previews, and technical foundations. Optionally runs Lighthouse and PageSpeed against a live URL. Reports findings with severity, offers direct fixes or /arc:detail plans. Use when asked to "audit SEO", "check SEO", "review SEO", or "is my site SEO-ready".
