SKILL.md

Sentry Commit Messages

Follow these conventions when creating commits for Sentry projects.

Prerequisites

Before committing, always check the current branch:

bash
git branch --show-current

If you're on main or master, you MUST create a feature branch first — unless the user explicitly asked to commit to main. Do not ask the user whether to create a branch; just proceed with branch creation. The create-branch skill should derive and create a suitable branch name automatically.

Use the create-branch skill to create the branch. After create-branch completes, verify the current branch has changed before proceeding:

bash
git branch --show-current

If still on main or master, stop — do not commit.

Format

<type>(<scope>): <subject>

<body>

<footer>

The header is required. Scope is optional. All lines must stay under 100 characters.

Commit Types

Type Purpose
feat New feature
fix Bug fix
ref Refactoring (no behavior change)
perf Performance improvement
docs Documentation only
test Test additions or corrections
build Build system or dependencies
ci CI configuration
chore Maintenance tasks
style Code formatting (no logic change)
meta Repository metadata
license License changes

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
  • Use real newlines in commit bodies; never include literal \n sequences

Commit Command Hygiene

When creating commits from the CLI, do not embed escaped newlines like \n inside -m strings. That produces literal backslash characters in the final commit message.

Prefer one of these patterns:

bash
git commit -m "type(scope): Subject" \
  -m "First paragraph with real line wrapping.

Second paragraph.

Fixes GH-1234
Co-Authored-By: (the agent's name and attribution byline)"
bash
git commit

Use the editor flow when the message needs careful formatting.

Footer: Issue References

Reference issues in the footer using these patterns:

Fixes GH-1234
Fixes #1234
Fixes SENTRY-1234
Refs LINEAR-ABC-123
  • Fixes closes the issue when merged
  • Refs links without closing

AI-Generated Changes

When changes were primarily generated by a coding agent, include the Co-Authored-By attribution in the commit footer. Agents should use their own identity:

Co-Authored-By: (the agent's name and attribution byline)

Example: Co-Authored-By: Claude Sonnet 4 <noreply@example.com>

This is the only indicator of AI involvement that should appear in commits. Do not add phrases like "Generated by AI", "Written with Claude", or similar markers in the subject, body, or anywhere else in the commit message.

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.

Fixes SENTRY-5678
Co-Authored-By: (the agent's name and attribution byline)

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.

Refs GH-1234

Refactor

ref: 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
Fixes SENTRY-9999

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

doc-coauthoring

Guide users through a structured workflow for co-authoring documentation. Use when user wants to write documentation, proposals, technical specs, decision docs, or similar structured content. This workflow helps users efficiently transfer context, refine content through iteration, and verify the doc works for readers. Trigger when user mentions writing docs, creating proposals, drafting specs, or similar documentation tasks.

gha-security-review

GitHub Actions security review for workflow exploitation vulnerabilities. Use when asked to "review GitHub Actions", "audit workflows", "check CI security", "GHA security", "workflow security review", or review .github/workflows/ for pwn requests, expression injection, credential theft, and supply chain attacks. Exploitation-focused with concrete PoC scenarios.

blog-writing-guide

Write, review, and improve blog posts for the Sentry engineering blog following Sentry's specific writing standards, voice, and quality bar. Use this skill whenever someone asks to write a blog post, draft a technical article, review blog content, improve a draft, write a product announcement, create an engineering deep-dive, or produce any written content destined for the Sentry blog or developer audience. Also trigger when the user mentions "blog post," "blog draft," "write-up," "announcement post," "engineering post," "deep dive," "postmortem," or asks for help with technical writing for Sentry. Even if the user just says "help me write about [feature/topic]" — if it sounds like it could become a Sentry blog post, use this skill.
