Write Pr

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

Concepts, examples, and FAQ (for large or feature-intensive PRs)

When a PR introduces a new system, several new types/APIs, or otherwise has enough surface area that a reviewer would benefit from a glossary, include extra explanatory sections above the standard ### Change type / ### Test plan / ### Release notes block. Skip these for small or focused PRs — they're for features and large refactors.

Pull from this menu, in roughly this order, using only what fits:

• Concepts — a table of the new terms/types the PR introduces, with Term | Type | Meaning columns. Use this when readers need a shared vocabulary to follow the rest of the description.
• Module augmentation — short code blocks showing how consumers extend the new types, when the PR exposes augmentable interfaces.
• Editor API / Component props — Method | Description and Prop | Type | Description tables for new public surface.
• Per-shape / per-feature breakdown — tables showing what each affected shape/module returns or accepts under the new system.
• Example — a realistic, copy-pastable code snippet showing how a default implementation uses the new system, plus a second snippet showing how a consumer would override it.
• FAQ — anticipated "How do I…?" questions with short code answers. Cover the obvious customization paths a downstream user will reach for first.
• New examples — bullet list of any new entries added under apps/examples/src/examples/, with a one-line description each, so reviewers know where to look for runnable demos.

Reference: tldraw/tldraw#8410 is a good worked example of all of these sections together.

These sections come before ### Change type. The standard ### Change type / ### Test plan / ### Release notes / ### API changes / ### Code changes blocks still appear at the bottom in the usual order.

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
• Templates — starter templates (templates/)
• Config/tooling — config files, lock files, lint config, CI, build scripts (eslint.config.*, yarn.lock, etc.)

### Code changes

| Section         | LOC change |
| --------------- | ---------- |
| Core code       | +10 / -2   |
| Tests           | +5 / -0    |
| Automated files | +0 / -1    |
| Documentation   | +2 / -0    |
| Apps            | +3 / -1    |
| Templates       | +0 / -0    |
| Config/tooling  | +1 / -0    |

Human notes (preserve exactly)

The PR author often writes a personal note at the very top of the description, prefaced with a "person" emoji such as 🅯 or 👨 (or similar). This block is human-written and readers trust it as such.

• When updating an existing PR description, if the body starts with a paragraph/section led by a person emoji, you MUST preserve it byte-for-byte exactly at the top — do not rewrite, reflow, reword, retitle, or "improve" it, even slightly.
• If the human note is longer than a single paragraph, it will be delimited at the end by a --- horizontal rule. Preserve everything from the person emoji through (and including) that --- exactly.
• If there is no ---, the human note is just the leading paragraph led by the person emoji.
• Make all your edits to the content below the human note (and below the --- if present).
• When creating a new PR, do not invent a human note — leave that for the author to add.

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
