# Pull Request Conventions

## Branch discipline

- **Never commit to `main` directly.** Create a branch: `<user>/<short-description>` (e.g. `mmansour/optimize-handler-allocs`).
- One logical change per commit. Write imperative messages: *"Add …"* not *"Added …"*.

## PR title format

PR titles must use a [Conventional Commits](https://www.conventionalcommits.org/) prefix:

| Prefix | When to use | Example |
|--------|-------------|---------|
| `feat:` | New feature or capability | `feat: add HTTP/2 support to hyper example` |
| `fix:` | Bug fix | `fix: render missing signals as empty` |
| `perf:` | Speed or memory improvement, measured | `perf: reduce allocations on hot paths` |
| `chore:` | Maintenance, refactoring, CI, docs, dependencies | `chore: move shared files to examples/app` |


The prefix is **lowercase**, followed by a colon and a space, then a short imperative description.

A `perf:` PR must report before/after numbers in its description - see the **perf** skill for how to measure.

## Linking PRs to issues

When a PR is meant to close a GitHub issue, include the keyword `Closes` followed by the issue number in the PR description body (not the title):

```
Closes #42
```

For multiple issues, use one per line:

```
Closes #42
Closes #43
```

> **Note:** Issue-linking keywords only work when the PR targets the repository's default branch. See [GitHub docs: linking a pull request to an issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/using-issues/linking-a-pull-request-to-an-issue#linking-a-pull-request-to-an-issue-using-a-keyword) for the full reference.

## PR description
Remove the Co-author-by line from the PR description. If you want to credit a co-author, add them as a reviewer instead. And check all the changes from its merge-base to get a detailed summary for the commit.

## Framework change PRs

For PRs touching core framework code (handler, parser, protocol, router, CLI runtime, FFI), apply the **code-review** skill checklist before opening the PR. It covers correctness, concurrency, performance, design, and style checks that complement the automated quality gate.
