AI assistance does not relieve contributors of responsibility for their work. "The AI did it" is not an excuse. Violations may result in contributions being closed without further comment.

addyosmani/agent-skills/AGENTS.md
Scope: This file configures agents working on the addyosmani/agent-skills repository itself. It is not meant to be copied into other projects or into a global agent configuration; the reusable assets are the skills in skills/, not this file. A collection of skills for Claude.ai and Claude Code for senior software engineers. Skills are packaged instructions and scripts that extend Claude and your coding agents capabilities. OpenCode uses a skill-driven execution model powered by the skill tool and this repository's /skills…

addyosmani/agent-skills/docs/agents.md
Specialist personas that play a single role with a single perspective. Each persona is a Markdown file consumed as a system prompt by your harness (Claude Code, Cursor, Copilot, etc.). Three layers, each with a distinct job: The user (or a slash command) is the orchestrator. Personas do not call other personas. Skills are mandatory hops inside a persona's workflow. This is the only orchestration pattern this repo endorses. See references/orchestration-patterns.md for the full pattern catalog and anti-patterns. /ship is…
addyosmaniSkillapi-and-interface-design
addyosmani/agent-skills/skills/api-and-interface-design/SKILL.md
Guides stable API and interface design. Use when designing APIs, module boundaries, or any public interface. Use when creating REST or GraphQL endpoints, defining type contracts between modules, or establishing boundaries between frontend and backend.
addyosmaniSkillbrowser-testing-with-devtools
addyosmani/agent-skills/skills/browser-testing-with-devtools/SKILL.md
Tests in real browsers via Chrome DevTools MCP. Use when building or debugging anything that runs in a browser. Use when you need to inspect the DOM, capture console errors, analyze network requests, profile performance, or verify visual output with real runtime data. Requires the chrome-devtools MCP server to be configured.
addyosmaniSkillci-cd-and-automation
addyosmani/agent-skills/skills/ci-cd-and-automation/SKILL.md
Automates CI/CD pipeline setup. Use when setting up or modifying build and deployment pipelines. Use when you need to automate quality gates, configure test runners in CI, or establish deployment strategies.
addyosmaniSkillcode-review-and-quality
addyosmani/agent-skills/skills/code-review-and-quality/SKILL.md
Conducts multi-axis code review. Use before merging any change. Use when reviewing code written by yourself, another agent, or a human. Use when you need to assess code quality across multiple dimensions before it enters the main branch. Use when asked to review a diff or a pull request, even when the diff is pasted inline.
addyosmaniSkillcode-simplification
addyosmani/agent-skills/skills/code-simplification/SKILL.md
Simplifies code for clarity. Use when refactoring code for clarity without changing behavior. Use when code works but is harder to read, maintain, or extend than it should be. Use when reviewing code that has accumulated unnecessary complexity.
addyosmaniSkillconstraint-driven-development
addyosmani/agent-skills/skills/constraint-driven-development/SKILL.md
Establishes a project's quality bar as a written contract and stops agents quietly lowering it. Interviews the user on which dimensions matter, supplies sane default thresholds when they have no number in mind, records everything in CONSTRAINTS.md, and watches the diff for a weakened bar — new @ts-ignore or eslint-disable suppressions, skipped or deleted tests, assertions stripped out, unimplemented stubs, thresholds edited down. Use when no quality bar is written down, when the user says "set up constraints" or "define our standards", when the user wants dimensions they care about — accessibility, web performance, coverage — set up as enforced constraints, when an agent keeps silencing checks or skipping tests to get to green, when you need a coverage or performance threshold and don't know what number to pick, or when an agent writes more code than anyone will read.
addyosmaniSkillcontext-engineering
addyosmani/agent-skills/skills/context-engineering/SKILL.md
Optimizes agent context setup. Use when starting a new session, when agent output quality degrades, when switching between tasks, or when you need to configure rules files and context for a project.
addyosmaniSkilldebugging-and-error-recovery
addyosmani/agent-skills/skills/debugging-and-error-recovery/SKILL.md
Guides systematic root-cause debugging. Use when tests fail, builds break, something that worked yesterday broke, behavior doesn't match expectations, or you encounter any unexpected error. Use when you need to figure out what broke and why — a systematic approach to finding and fixing the root cause rather than guessing.
addyosmaniSkilldeprecation-and-migration
addyosmani/agent-skills/skills/deprecation-and-migration/SKILL.md
Manages deprecation and migration. Use when removing old systems, APIs, or features. Use when migrating users from one implementation to another. Use when migrating a database schema in production, such as renaming or dropping a column without downtime (expand/contract). Use when deciding whether to maintain or sunset existing code.
addyosmaniSkilldocumentation-and-adrs
addyosmani/agent-skills/skills/documentation-and-adrs/SKILL.md
Records decisions and documentation. Use when you need to document an architecture decision (ADR) or the reasoning behind a design choice, when changing public APIs, shipping features, or when you need to record context that future engineers and agents will need to understand the codebase.
addyosmaniSkilldoubt-driven-development
addyosmani/agent-skills/skills/doubt-driven-development/SKILL.md
Subjects every non-trivial decision to a fresh-context adversarial review before it stands. Use when you want every assumption cross-examined before proceeding, when stress-testing a plan for hidden failure modes, when correctness matters more than speed, when working in unfamiliar code, when stakes are high (production auth, security-sensitive logic, a high-stakes migration, irreversible operations), or any time a confident output would be cheaper to verify now than to debug later.
addyosmaniSkillfrontend-ui-engineering
addyosmani/agent-skills/skills/frontend-ui-engineering/SKILL.md
Builds production-quality, accessible, responsive user-facing UIs. Use when building or modifying interfaces and pages, creating components, implementing layouts, meeting WCAG accessibility requirements, managing state, or when the output needs to look and feel production-quality rather than AI-generated.
addyosmaniSkillgit-workflow-and-versioning
addyosmani/agent-skills/skills/git-workflow-and-versioning/SKILL.md
Structures git workflow practices. Use when making any code change. Use when committing, branching, resolving conflicts, splitting uncommitted work in a messy working tree into clean atomic commits, opening or reviewing a pull request (PR), pushing to a remote, or when you need to organize work across multiple parallel streams. Use when cutting a release, choosing a semantic version bump, tagging, or writing a changelog.
addyosmaniSkillidea-refine
addyosmani/agent-skills/skills/idea-refine/SKILL.md
Refines raw ideas into sharp, actionable concepts through structured divergent and convergent thinking. Use when an idea is still vague, when you need to stress-test assumptions before committing to a plan, or when you want to expand options before converging on one. Triggers on "ideate", "refine this idea", or "stress-test my plan".
addyosmaniSkillincremental-implementation
addyosmani/agent-skills/skills/incremental-implementation/SKILL.md
Delivers changes incrementally in thin, verifiable slices. Use when implementing any feature or change that touches more than one file, or when picking up the next task from a plan. Use when rolling a change out behind a feature flag, when you're about to write a large amount of code at once, or when a task feels too big to land in one step.
Agent instruction files
What are agent instruction files?
Plain text files in a repository that tell a coding agent how the project works: commands to run, conventions to follow and things to avoid. CLAUDE.md, AGENTS.md, cursor rules and skills are the common kinds.
CLAUDE.md or AGENTS.md?
CLAUDE.md is read by Claude Code. AGENTS.md is an open format that Codex, Cursor and other agents read. Many projects keep one and point the other at it.
What is a skill?
A folder with a SKILL.md that describes one capability, such as filling PDFs or reviewing code. The agent loads it only when the task calls for it.
Can I search my own team's files too?
Your agents already can, over MCP, limited to the files you're allowed to read. Searching them from this page is coming.
