Claude Code Skills & Plugins

Website: wst2002.github.io/claude-code-skills

Ready-to-use Claude Code skills and plugins that make AI coding agents faster, more reliable, and honest about their work.

Install

Skills — all of them, or pick one:

npx skills add WST2002/claude-code-skills
npx skills add WST2002/claude-code-skills --skill security-audit

Or copy any folder from skills/ into ~/.claude/skills/ (Windows: %USERPROFILE%\.claude\skills\).

Plugins — inside Claude Code:

/plugin marketplace add WST2002/claude-code-skills
/plugin install issue-to-pr@claude-code-skills
/plugin install proof-of-done@claude-code-skills

Plugins

Plugin	What it does
issue-to-pr	/fix-issue 123 — from a GitHub issue, Jira ticket or description to a tested fix and a draft pull request, in one command
proof-of-done	Blocks the agent from finishing after code changes until tests, build or lint have passed after the last edit, and catches tests skipped, weakened or deleted to get there

proof-of-done in a real Claude Code session: Claude skipped the tests, the plugin made it run them, and they found a bug it had missed.

Skills

Code quality

Skill	Use it to
code-review	Review a PR, branch or diff for real defects, each with a concrete failing scenario
bug-debugger	Find the root cause of a bug, fix it, and prove the fix with a regression test
test-writer	Write tests that fail when behavior breaks, in your project's framework and style
refactor-planner	Refactor in small, safe, test-backed steps without changing behavior
proof-of-done-lite	Make the agent show test and build results before saying "done"

Testing and QA

Skill	Use it to
test-case-generator	Turn a requirement or user story into manual test cases: positive, negative, boundary, permission and state
test-plan-writer	Write a risk-based test plan with scope, environments and measurable entry/exit criteria
bug-report-writer	Write bug reports developers can reproduce on the first try
playwright-e2e-tests	Write reliable Playwright end-to-end tests with user-facing locators and no sleeps
api-test-writer	Write API tests for status codes, schemas, validation, auth and side effects
flaky-test-fixer	Reproduce and fix tests that pass and fail without code changes

Everyday development

Skill	Use it to
codebase-onboarding	Understand an unfamiliar codebase fast: how to run it, the map, one real request flow
dependency-upgrade	Upgrade packages and frameworks in safe steps, following migration guides
changelog-writer	Write release notes and pick the next version from git history

Security and performance

Skill	Use it to
security-audit	Find exploitable vulnerabilities in any codebase, with file:line evidence, attack scenario and fix
web-performance-audit	Find why a site is slow, tied to LCP, INP, CLS and bundle size, with expected gains
accessibility-audit	Check keyboard, screen reader, contrast and ARIA issues mapped to WCAG 2.2 AA
seo-audit	Make pages crawlable and indexable: meta tags, canonical, sitemap, structured data

UI/UX design

For designers too: these skills also work in the Claude app, with a screenshot, a Figma frame or your research notes. No terminal needed:

1. Download the skill's ZIP from its page on the website.
2. In Claude, turn on Code execution (Settings → Capabilities).
3. Open Customize → Skills, click +, choose Upload a skill and pick the ZIP.

design-review turns a screenshot into a shareable report: numbered pins on the screen, exact contrast ratios measured from the pixels, and a concrete fix for each finding. Open the example report.

Skill	Use it to
design-review	Get senior-designer feedback on a screen: usability, hierarchy, accessibility and missing states, each with a concrete fix, as a report with numbered pins on the screenshot
ux-research-synthesis	Turn interview notes and transcripts into findings with quotes, participant counts and "how might we" opportunities
design-handoff-spec	Write the developer handoff: every state, edge case, breakpoint and interaction, with open questions instead of guesses
ux-writing	Write or review buttons, error messages, empty states and other UI text: clear, short and consistent
figma-design-compare	Check a website, web app or mobile screen against its Figma frame: screenshots plus exact font, color, spacing and size values

Architecture

Skill	Use it to
database-schema-design	Design a schema from scratch or review one for integrity, indexes and safe migrations
api-design-review	Design or review REST APIs: naming, status codes, errors, pagination, breaking changes
architecture-diagram	Draw system, sequence, ERD or deployment diagrams in Mermaid, from the real code

DevOps

Skill	Use it to
dockerize-app	Write a small, secure Dockerfile and docker-compose for Node, Python, Java or Go, and verify it runs
github-actions-ci	Set up or fix GitHub Actions CI with caching, services and least-privilege permissions

Writing

Skill	Use it to
git-commit-writer	Write commit messages that match your repo's convention and split mixed changes
readme-writer	Write a README from the real codebase, with verified commands and nothing invented
prd-writer	Write a PRD with evidence, measurable goals and testable acceptance criteria

Every skill uses the same approach: a clear method, a fixed output format, and a verification step so results are specific and low on false positives.

Tested: skills are benchmarked with and without the skill on sample projects with seeded bugs and answer keys — see benchmarks.

Plugins vs skills

• Skills are instructions. Claude loads them when your request matches.
• Plugins can enforce behaviour with hooks, for example stopping the agent until checks pass.

Contributing

See CONTRIBUTING.md. Ideas for new skills are welcome as issues.
