Writing pull requests

Standards for PR titles and descriptions in tldraw/tldraw.

PR title

Use semantic PR titles (Conventional Commits format):

<type>(<scope>): <description>

Types

• feat - New feature
• fix - Bug fix
• docs - Documentation only
• refactor - Code change that neither fixes a bug nor adds a feature
• perf - Performance improvement
• test - Adding or fixing tests
• chore - Maintenance tasks

Scope (optional)

A noun describing the affected area: fix(editor):, feat(sync):, docs(examples):

Examples

• feat(editor): add snap threshold configuration option
• fix(arrows): correct binding behavior with rotated shapes
• docs: update sync documentation
• refactor(store): simplify migration system

PR body

Use this template:

<description paragraph>

### Change type

- [x] `bugfix` | `improvement` | `feature` | `api` | `other`

### Test plan

1. Step to test...
2. Another step...

- [ ] Unit tests
- [ ] End to end tests

### Release notes

- Brief description of changes for users

Description paragraph

Start with: "In order to X, this PR does Y."

• Keep it specific - avoid vague phrases like "improve user experience"
• Link related issues in the first paragraph
• Don't expect readers to also read the linked issue

Change type

• Tick exactly one type with [x]
• Delete unticked items

Test plan

• List manual testing steps if applicable
• Remove the numbered list if changes cannot be manually tested
• Tick checkboxes for included test types

Release notes

• Write brief notes describing user-facing changes
• Use imperative mood: "Add...", "Fix...", "Remove..."
• Omit this section entirely for internal work (CI, tooling, tests, etc.) that has no user-facing impact

API changes section

Include when changes affect api-report.md:

### API changes

- Added `Editor.newMethod()` for X
- Breaking! Removed `Editor.oldMethod()`
- Changed `Editor.method()` to accept optional `options` parameter

Code changes table

Create a table that includes net LOC changes for each of the following sections. The sum of all rows must match the total PR diff. Omit rows with no changes.

• Core code — SDK packages (packages/) source, excluding tests and API reports

• Tests — unit tests, e2e tests (*.test.*, e2e/)

• Automated files — generated files (e.g. api-report.api.md, snapshots)

• Documentation — docs site and examples (apps/docs/, apps/examples/)

• Apps — application code (apps/dotcom/, apps/mcp-app/, apps/vscode/, etc.), excluding e2e tests

Related issues

Search for and link relevant issues that this PR addresses.

Important

• Never include "Generated with Claude Code" unless the PR directly relates to Claude Code
• Never use title case for descriptions - use sentence case
• Never put yourself as co-author of any commits
• Always include an API changes section if the PR has changes to any api-report.md
