Grep-based reverse dependency analysis — injected into planner, reviewer, and deep-review agents. Computes which files are affected by changes to a set of seed files. Not invoked directly.

This skill should be used when the user asks to "brainstorm", "refine an idea", "flesh out a feature", "define requirements". Guides interactive refinement of rough ideas into concise, actionable feature specifications. Focuses on the "what" and architecture — never the "how".

This is the default skill for all development work. It orchestrates the entire development lifecycle from idea to merge-ready code, coordinating multiple agents for brainstorming, planning, implementation, review, documentation, and final approval. Use this for any development task that is non-trivial and could benefit from structured planning, parallel execution, and rigorous review or require more than 3 lines of code changed.

Retrieves authoritative, up-to-date technical documentation, API references, configuration details, and code examples for any developer technology. Use this skill whenever answering technical questions or writing code that interacts with external technologies. This includes libraries, frameworks, programming languages, SDKs, APIs, CLI tools, cloud services, infrastructure tools, and developer platforms. Common scenarios: - looking up API endpoints, classes, functions, or method parameters - checking configuration options or CLI commands - answering "how do I" technical questions - generating code that uses a specific library or service - debugging issues related to frameworks, SDKs, or APIs - retrieving setup instructions, examples, or migration guides - verifying version-specific behavior or breaking changes Prefer this skill whenever documentation accuracy matters or when model knowledge may be outdated.

Implement tasks using TDD. Accepts a plan or specific task description. Runs implementer agents in parallel where possible.

Design intelligence for UI/UX — injected into the frontend-planner agent. Provides BM25-searchable database of 67 styles, 161 color palettes, 57 font pairings, 160 animated component patterns, 161 industry rules, plus framework-agnostic design guidelines. Not invoked directly.

Domain logic for TDD methodology — injected into agents that implement code using test-driven development. Not invoked directly.

Create a detailed TDD implementation plan with parallel tasks from a feature spec or description.

This skill should be used when the user runs "/setup", "setup my project", "initialize CLAUDE.md", "create CLAUDE.md", or wants to set up the devline clarification protocol for a project. Creates a CLAUDE.md with the clarification protocol and interactively generates a minimal devline.local.md with only non-default settings.

Use whenever text is being produced or edited that could be public/published. Covers 4 purposes — communication (emails, LinkedIn), project content (READMEs, website copy, docs), scientific writing (papers, theses), and fiction (books, stories). Humanize AI-generated text by removing common AI writing patterns. Triggers on "humanize this", "make this sound human", "fix AI writing", "rewrite this naturally", "write a blog post", "draft an email", "write a README", "translate this", "translate to German", "auf Deutsch", "write a chapter", "scientific paper", or any request to produce, edit, or translate text meant for human readers.

Standalone design skill for individual components, color themes, brand identity, or fitting within an existing project theme. Use when the user asks to "design a button", "create a color theme", "create a brand identity", "make this match our site", "show me 6 card styles", "add a modal to the brand", or any targeted UI design request. Also triggers on mood-based requests like "warm dark theme", "cool minimalist colors", "playful typography".

Final comprehensive pull request review — the last gate before merge. Checks security, credentials, code quality, tech debt, conventions, and plan compliance.

Domain logic for cloud infrastructure and DevOps — injected into the devops agent. Provides guidance on cloud-native development, IaC, containerization, CI/CD, and deployment. Not invoked directly.

Domain logic for systematic debugging — injected into the debugger agent. Provides common bug patterns and debugging tools reference. Not invoked directly.

Domain logic for documentation — injected into the docs-keeper agent. Provides guidance on creating and maintaining separate documentation files (README, API docs, guides). Not invoked directly.

Brand voice, visual identity, messaging frameworks, asset management, brand consistency. Activate for "brand", "brand identity", "voice", "visual identity", "brand guidelines", "messaging framework", "brand consistency", branded content, tone of voice, marketing assets, brand compliance, style guides.

Patch CVE vulnerabilities across one or many repositories. Invoke with a list of CVEs and optionally specific repo names. Researches each CVE (affected package, ecosystem, versions), then launches dependency-patcher agents to update, verify, commit, and push. Use this skill whenever the user mentions CVEs, security vulnerabilities in dependencies, patching dependencies, or updating packages for security fixes — even if they don't say 'CVE' explicitly but reference a security advisory or vulnerable dependency.

Graphic design skill: logo design (55 styles, 30 color palettes, 25 industry guides), corporate identity programs (50+ deliverables), icon design (15 styles, SVG), banner design (22 art direction styles, social/ads/web/print), HTML presentations (Chart.js, copywriting formulas), social photos (multi-platform). Trigger on: logo, logo design, corporate identity, CIP, banner, social media banner, presentation, slides, icon design, social photos, graphic design, visual assets.

Domain logic for dependency management — injected into the dependency-patcher agent. Provides ecosystem detection, version update mechanics, build/test verification, and commit/push workflows across all major package managers. Not invoked directly.

Domain logic for complex dependency migrations — injected into the dependency-migrator agent. Provides methodology for researching migration guides, using ecosystem migration tools, refactoring code for breaking API changes, handling package renames, and verifying correctness. Not invoked directly.

Migrate dependencies to new major versions — handles breaking changes, API refactoring, package renames, and behavioral differences. Researches migration guides and tooling, then launches dependency-migrator agents. Use this skill when the user wants to upgrade a dependency across a major version, migrate from one library to another (e.g., Moment.js to date-fns), prepare for EOL by upgrading early, or handle any dependency transition that involves more than just changing a version number. Triggers on phrases like 'migrate', 'upgrade to v2', 'move from X to Y', 'end of life', 'EOL', 'deprecated', 'major version upgrade', 'breaking changes'.

This skill should be used when the user asks to "debug this", "fix this bug", "find the root cause", "investigate an error", "troubleshoot", "why is this failing", "trace the issue", or mentions errors, exceptions, stack traces, or unexpected behavior that needs investigation. Launches the debugger agent for systematic root cause analysis.

Perform an in-depth code review of recent changes. Checks correctness, security, performance, and code quality.
