conventional-commit
Create conventional commit messages following best conventions. Use when committing code changes, writing commit messages, or formatting git history. Follows conventional commits specification.
What this skill does
# Conventional Commit Messages Follow these conventions when creating commits. ## Prerequisites Before committing, ensure you're working on a feature branch, not the main branch. ```bash # Check current branch git branch --show-current ``` If you're on `main` or `master`, create a new branch first: ```bash # Create and switch to a new branch git checkout -b <type>/<short-description> ``` Branch naming should follow the pattern: `<type>/<short-description>` where type matches the commit type (e.g., `feat/add-user-auth`, `fix/null-pointer-error`, `refactor/extract-validation`). ## Format ``` <type>(<scope>): <subject> <body> <footer> ``` The header is required. Scope is optional. All lines must stay under 100 characters. ## Commit Types | Type | Purpose | |------|---------| | `build` | Build system or CI changes | | `chore` | Routine maintenance tasks | | `ci` | Continuous integration configuration | | `deps` | Dependency updates | | `docs` | Documentation changes | | `feat` | New feature | | `fix` | Bug fix | | `perf` | Performance improvement | | `refactor` | Code refactoring (no behavior change) | | `revert` | Revert a previous commit | | `style` | Code style and formatting | | `test` | Tests added, updated or improved | ## Subject Line Rules - Use imperative, present tense: "Add feature" not "Added feature" - Capitalize the first letter - No period at the end - Maximum 70 characters ## Body Guidelines - Explain **what** and **why**, not how - Use imperative mood and present tense - Include motivation for the change - Contrast with previous behavior when relevant ## Conventional Commits The commit contains the following structural elements, to communicate intent to the consumers of your library: - fix: a commit of the type fix patches a bug in your codebase (this correlates with PATCH in Semantic Versioning). - feat: a commit of the type feat introduces a new feature to the codebase (this correlates with MINOR in Semantic Versioning). - BREAKING CHANGE: a commit that has a footer BREAKING CHANGE:, or appends a ! after the type/scope, introduces a breaking API change (correlating with MAJOR in Semantic Versioning). A BREAKING CHANGE can be part of commits of any type. - types other than fix: and feat: are allowed, for example @commitlint/config-conventional (based on the Angular convention) recommends build:, chore:, ci:, docs:, style:, refactor:, perf:, test:, and others. - footers other than BREAKING CHANGE: <description> may be provided and follow a convention similar to git trailer format. ## Examples ### Simple fix ``` fix(api): Handle null response in user endpoint The user API could return null for deleted accounts, causing a crash in the dashboard. Add null check before accessing user properties. ``` ### Feature with scope ``` feat(alerts): Add Slack thread replies for alert updates When an alert is updated or resolved, post a reply to the original Slack thread instead of creating a new message. This keeps related notifications grouped together. ``` ### Refactor ``` refactor: Extract common validation logic to shared module Move duplicate validation code from three endpoints into a shared validator class. No behavior change. ``` ### Breaking change ``` feat(api)!: Remove deprecated v1 endpoints Remove all v1 API endpoints that were deprecated in version 23.1. Clients should migrate to v2 endpoints. BREAKING CHANGE: v1 endpoints no longer available ``` ## Revert Format ``` revert: feat(api): Add new endpoint This reverts commit abc123def456. Reason: Caused performance regression in production. ``` ## Principles - Each commit should be a single, stable change - Commits should be independently reviewable - The repository should be in a working state after each commit ## References - [Conventional Commits Specification](https://www.conventionalcommits.org/en/v1.0.0/#specification)
Related in Writing & Docs
jax-development
IncludedUse this skill when the user is writing, debugging, profiling, refactoring, reviewing, benchmarking, parallelising, exporting, or explaining JAX code, or when they mention JAX, jax.numpy, jit, grad, value_and_grad, vmap, scan, lax, random keys, pytrees, jax.Array, sharding, Mesh, PartitionSpec, NamedSharding, pmap, shard_map, Pallas, XLA, StableHLO, checkify, profiler, or the JAX repo. It helps turn NumPy or PyTorch-style code into pure functional JAX, fix tracer/control-flow/shape/PRNG bugs, remove recompiles and host-device syncs, choose transforms and sharding strategies, inspect jaxpr/lowering/IR, and benchmark compiled code correctly.
nature-article-writer
IncludedDrafts, rewrites, diagnostically critiques, and style-calibrates primary research manuscripts for Nature and Nature Portfolio journals. Use when the user wants a Nature-style title, summary paragraph or abstract, introduction, results, discussion, methods, figure legends, presubmission enquiry, cover letter, reviewer response, or when a scientific draft sounds generic, jargon-heavy, structurally weak, or AI-ish and needs precise, broad-reader-friendly prose without inventing data, analyses, or references. Best for primary research articles and letters rather than reviews or press releases unless explicitly adapting one.
deckrd
IncludedDocument-driven framework that derives requirements, specifications, implementation plans, and executable tasks from goals through structured AI dialogue. Use when user says "write requirements", "create spec", "plan implementation", "derive tasks", "structure this feature", "break down into tasks", or "document this module". Also use for reverse engineering existing code into docs (/deckrd rev). Do NOT use for direct code writing — use /deckrd-coder after tasks are generated. Do NOT use when the user only wants to run or fix existing code without planning.
clinical-decision-support
IncludedGenerate professional clinical decision support (CDS) documents for pharmaceutical and clinical research settings, including patient cohort analyses (biomarker-stratified with outcomes) and treatment recommendation reports (evidence-based guidelines with decision algorithms). Supports GRADE evidence grading, statistical analysis (hazard ratios, survival curves, waterfall plots), biomarker integration, and regulatory compliance. Outputs publication-ready LaTeX/PDF format optimized for drug development, clinical research, and evidence synthesis.
handling-sf-data
IncludedSalesforce data operations with 130-point scoring. Use this skill to create, update, delete, bulk import/export, generate test data, and clean up org records using sf CLI and anonymous Apex. TRIGGER when: user creates test data, performs bulk import/export, uses sf data CLI commands, needs data factory patterns for Apex tests, or needs to seed/clean records in a Salesforce org. DO NOT TRIGGER when: SOQL query writing only (use querying-soql), Apex test execution (use running-apex-tests), or metadata deployment (use deploying-metadata).
accelint-ac-to-playwright
IncludedConvert and validate acceptance criteria for Playwright test automation. Use when user asks to (1) review/evaluate/check if AC are ready for automation, (2) assess if AC can be converted as-is, (3) validate AC quality for Playwright, (4) turn AC into tests, (5) generate tests from acceptance criteria, (6) convert .md bullets or .feature Gherkin files to Playwright specs, (7) create test automation from requirements. Handles both bullet-style markdown and Gherkin syntax with JSON test plan generation and validation.
