# Changelog Rules

The changelog is kept in `CHANGELOG.md` at the project root. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and projects using these conventions adhere to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## File Structure

```markdown

# Changelog

All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## Changelog-Worthiness

Not every change belongs in a changelog. Changelogs are for humans, not machines.

**Skip** changes that are purely internal:

- Refactoring with no user-facing impact

- Code formatting, linting, whitespace

- Test additions or modifications (unless they indicate a fixed bug)

- CI/CD configuration

- Developer tooling (linters, editor config)

- Documentation updates (README, comments, docstrings)

- Dependency bumps with no behavior change

**Include** changes that affect users:

- New features or capabilities

- Changes to existing behavior

- Deprecated or removed functionality

- Bug fixes

- Security patches

## Entry Format

- Imperative present tense without trailing periods (e.g., "Add dark mode support")

- One bullet point per distinct change

- Concise but complete. Include enough context that users understand the impact.

### User-Centric Writing

Entries describe what changed **for the user**. Focus on outcomes and impact.

- Lead with a user-visible verb: "Add", "Fix", "Improve", "Allow", "Prevent", "Show", "Check". Avoid developer-centric verbs like "Enforce", "Implement", "Refactor", "Handle", "Register".

- Describe the experience, not the mechanism.

- When a change prevents a problem or protects the user, say what it does for them.

## PR and Issue References

Reference both the PR and any associated GitHub issue in each entry using inline parenthetical format with linked numbers in ascending order.

```markdown

- Add dark mode support ([#38](https://github.com/owner/repo/issues/38), [#42](https://github.com/owner/repo/pull/42))

```

To discover associated issues for a PR, run:

```bash

gh pr view <number> --json closingIssuesReferences --jq '.closingIssuesReferences[].number'

```

- If there is no associated issue, reference only the PR

- If there is no PR (e.g., backfilling from git tags), omit references

## Change Types

Standard types in this order when present: Added, Changed, Deprecated, Removed, Fixed, Security. Omit empty sections.

## Section Format

- Unreleased section always present at the top

- ISO 8601 dates (`YYYY-MM-DD`)

- Reverse chronological order (newest first)

- Blank line between each section header and its content

- Version comparison links at the bottom, derived from the repository's remote URL

- Detect whether the project uses `v`-prefixed tags (e.g., `v1.0.0`) or bare tags (e.g., `1.0.0`) and match that convention in comparison links
