codex
Use when the user asks to run Codex CLI (codex exec, codex resume) or references OpenAI Codex for code analysis, refactoring, or automated editing. Uses GPT-5.3-Codex by default for state-of-the-art software engineering.
interview
Interview me about anything in depth
gemini
Use when the user asks to run Gemini CLI for code review, plan review, or big context (>200k) processing. Ideal for comprehensive analysis requiring large context windows. Uses Gemini 3 Pro by default for state-of-the-art reasoning and coding.
agent-change-walkthrough
Generates a narrative walkthrough of AI-authored code changes. Use after implementation to explain what changed, why, and how it behaves.
constitution-compliance-review
Evaluate plugin commands, agents, and skills against Anthropic Constitution principles. Score alignment on reasoning-based vs rule-based instruction spectrum, identify improvement opportunities. Use when the user wants to audit, score, or review the quality of a command, agent, or skill — e.g. "review this skill", "audit this command", "is this agent well-written", "score this against constitutional principles", or "check this for rule-based patterns".
finish-branch
Post-merge cleanup workflow. Detects PR merge, switches to main, pulls latest, runs tests, and removes worktree if exists. Use after PR is merged to clean up.
judgment-eval
Evaluates agent judgment quality through scenario-based testing in-conversation. Use when the user wants to test, validate, or stress-test an agent, skill, or command definition — e.g. "test this agent", "evaluate this skill", "does this prompt handle edge cases", "check this agent's judgment", or after writing or modifying any agent/skill/command .md file.
system-prompt-clinic
Interactive skill that diagnoses and transforms system prompts from rule-based to reasoning-based using Constitutional AI principles. Use when the user wants to improve, rewrite, or transform any system prompt, command, agent, or skill — e.g. "improve this prompt", "make this less rigid", "transform this rule-based command", "optimize this agent", or "this skill keeps breaking on edge cases".
tdd
TDD enforcement during implementation. Reads `tdd:` setting from CLAUDE.md. Modes - strict (human approval for escape), soft (warnings), off (disabled). Auto-invoked by /implement.
test
Write or review tests following Kent C. Dodds testing principles - flat structure, composable setup, disposable fixtures. Use when the user asks to write tests, review tests, or convert legacy tests.
x-search
Search X/Twitter for real-time developer discourse, product feedback, community sentiment, and expert opinions. Use when user says "x search", "search x for", "search twitter for", "what are people saying about", or needs recent X discourse for context (library releases, API changes, product launches, industry discussion). Also use when researching a library, framework, API, or product to supplement web search with real-time community signal — e.g. "research Bun", "what do devs think of Hono", "is Turso production-ready".
agent-native-architecture
This skill should be used when building AI agents using prompt-native architecture where features are defined in prompts, not code. Use it when creating autonomous agents, designing MCP servers, implementing self-modifying systems, or adopting the "trust the agent's intelligence" philosophy.
agent-ready-repo-setup
|
ask-oracle
This skill should be used when solving hard questions, complex architectural problems, or debugging issues that benefit from GPT-5 Pro or GPT-5.1 thinking models with large file context. Use when standard Claude analysis needs deeper reasoning or extended context windows.
avoid-feature-creep
Prevent feature creep when building software, apps, and AI-powered products. Use this skill when planning features, reviewing scope, building MVPs, managing backlogs, or when a user says "just one more feature." Helps developers and AI agents stay focused, ship faster, and avoid bloated products.
check-env-keys
Verify which environment variable keys are present in .env files or shell environment without exposing their values. Use when you need to check env configuration or compare keys between .env files.
de-slop
This skill should be used to remove AI-generated artifacts and unnecessary code before committing. Integrates with desloppify CLI for quantitative scoring and directed fixes. Falls back to LLM-based pattern detection when desloppify is unavailable.
principal-hierarchy-audit
Audits system prompts and plugin configurations against Anthropic's Constitutional principal hierarchy to identify instructions that conflict with Claude's training, attempt to weaponize Claude against users, violate inalienable user protections, or exceed operator permission boundaries.
prompt-as-onboarding
Generate reasoning-based system prompts from product context. Takes product information as input, outputs a Constitution-aligned system prompt following the "onboarding document" structure.
worktree
Create an isolated git worktree for feature development with automatic setup. Use when starting work on a new feature branch to get a clean, fully-configured workspace without polluting your main checkout.
