testing-codegen
by biomejs
Guide for testing workflows and code generation commands in Biome. Use when running tests, managing snapshots, creating changesets, or generating code.

bedtools-genomic-intervals
by jaechang-hits
"Toolkit for genomic interval operations on BED, BAM, GFF, VCF files. Find overlapping regions, merge adjacent intervals, calculate coverage depth, extract FASTA sequences, find nearest features, and manipulate interval coordinates. Essential for ChIP-seq peak annotation, target region filtering, and genome arithmetic. Use tabix instead for indexed single-region queries; use deeptools for normalized bigWig coverage."
esphome-devices
by tonylofgren
Use when user EXPLICITLY requests "ESPHome", "ESP32", "ESP8266", or device firmware. NOT for: Home automations (use home-assistant or node-red skill).
ha-integration-dev
by tonylofgren
Use when user EXPLICITLY requests "custom integration", "custom component", "Python for HA", "HACS", or "config_flow". NOT for: YAML automations (use home-assistant skill), Node-RED flows (use node-red skill), ESPHome device configs (use esphome skill).
code-review
by sammcj
Use this skill after completing multiple, complex software development tasks before informing the user that work is complete.
rust-engineer
by sammcj
Acquire expert Rust developer specialisation in rust systems programming, memory safety, and zero-cost abstractions. Masters ownership patterns, async programming, and performance optimisation for mission-critical applications.
Create database migration
by TryGhost
Create a database migration to add a table, add columns to an existing table, add a setting, or otherwise change the schema of Ghost's MySQL database.
code-change-summarizer
by ArabelaTso
"Generates clear and structured pull request descriptions from code changes. Use when Claude needs to: (1) Create PR descriptions from git diffs or code changes, (2) Summarize what changed and why, (3) Document breaking changes with migration guides, (4) Add technical details and design decisions, (5) Provide testing instructions, (6) Enhance descriptions with security, performance, and architecture notes, (7) Document dependency changes. Takes code changes as input, outputs comprehensive PR description in Markdown."
pytest-runner
by saleor
Run pytest tests with automatic virtual environment activation. Use this skill whenever running tests, executing pytest, or when asked to "run tests", "test this", or any test execution task. Ensures venv is always activated before pytest runs.
testing
by mcouthon
"Behavioral testing strategy — deciding what to test and how. Use when writing tests, reviewing test quality, or fixing tests that test mocks instead of behavior. Triggers on: 'use testing mode', 'write tests', 'test strategy', 'tests are brittle', 'tests test mocks', 'improve test quality', 'what should I test'. Full access mode - can write and run tests."
perf-theory-tester
by ComposioHQ
"Use when running controlled perf experiments to validate hypotheses."
research-synthesis
by poemswe
You must use this when merging findings from multiple studies into a coherent narrative with grounded evidence.
testing-integration
by yonatangross
Integration and contract testing patterns — API endpoint tests, component integration, database testing, Pact contract verification, property-based testing, and Zod schema validation. Use when testing API boundaries, verifying contracts, or validating cross-service integration.
prd-to-goal
by yonatangross
"Decomposes a PRD, issue, or spec into a copy-pasteable single /goal until ..., or stop after N turns line. Use when running /goal against a spec, to reduce acceptance criteria to AND-joined boolean assertions."
review-pr
by yonatangross
"PR review using parallel specialized agents for code quality, security, testing, architecture, and performance analysis. Synthesizes findings into a review report with conventional comments (praise/issue/suggestion/nitpick) and approve or request-changes verdict. Use when reviewing pull requests, conducting security audits, or validating changes before merge."
storybook-testing
by yonatangross
Storybook 10 testing patterns with Vitest integration, ESM-only distribution, CSF3 typesafe factories, play() interaction tests, Chromatic TurboSnap visual regression, module automocking, accessibility addon testing, and autodocs generation. Use when writing component stories, setting up visual regression testing, configuring Storybook CI pipelines, or migrating from Storybook 9.
testing-e2e
by yonatangross
End-to-end testing patterns with Playwright — page objects, AI agent testing, visual regression, accessibility testing with axe-core, and CI integration. Use when writing E2E tests, setting up Playwright, implementing visual regression, or testing accessibility.
architecture-patterns
by yonatangross
Architecture validation and patterns for clean architecture, backend structure enforcement, project structure validation, test standards, and context-aware sizing. Use when designing system boundaries, enforcing layered architecture, validating project structure, defining test standards, or choosing the right architecture tier for project scope.
fix-issue
by yonatangross
"Fixes GitHub issues with parallel analysis. Use to debug errors, resolve regressions, fix bugs, or triage issues."
