Changelog Fragments

CHANGELOG Fragments Skill

Use this skill when creating or working with CHANGELOG fragments. Fragments are permanent records of changes, stored in ./docs/changelog/.

This skill is the replacement for the old changelog_create command.

Purpose

Changelog fragments prevent merge conflicts when multiple branches are developed in parallel. Each change gets its own file that stays as permanent documentation.

Directory Layout

Fragments are stored in ./docs/changelog/ at the project root. Create this directory on demand when writing the first fragment.

Default Workflow

When the user wants to record a completed change:

1. Determine the description from the request or the current session
2. Create ./docs/changelog/ if it does not exist
3. Generate the filename using the Europe/Stockholm calendar date and a short kebab-case summary
4. Classify the fragment as feature, fix, chore, docs, refactor, test, or perf
5. Gather related references from local docs when available:
   • docs/decisions/
   • docs/specs/
   • thoughts/shared/devlog/
   • thoughts/shared/plans/
   • thoughts/shared/research/
   • GitHub issues, PRs, or beads IDs
6. Write the fragment using template.md

Ask the user for missing metadata only when it cannot be inferred confidently.

File Naming Convention

YYYY-MM-DD_brief-description.md

Examples:

• 2025-11-19_oauth-token-refresh.md
• 2025-11-05_sync-database-tracking.md
• 2025-12-03_hydration-error-fix.md

Template

See template.md in this skill directory for the fragment format.

Fragment Types

• feature: New features or enhancements
• fix: Bug fixes
• chore: Maintenance tasks, dependency updates
• docs: Documentation changes
• refactor: Code refactoring without behavior changes
• test: Test additions or improvements
• perf: Performance improvements

When to Create a Fragment

Create a fragment for:

• Completing a planned feature or fix
• Making a breaking change
• Significant refactoring or architecture changes
• Important bug fixes
• Documentation improvements that affect users

Skip fragments for:

• Work-in-progress commits
• Typo fixes in comments
• Small documentation tweaks
• Personal experiments

Cross-Referencing

Fragments should link to related documentation. Use the frontmatter fields:

Example:

---
date: 2025-11-20
type: feature
related_adr: docs/decisions/2025-11-18_use-inngest-for-workflows.md
related_spec: docs/specs/sync-status-tracking.md
related_devlog: thoughts/shared/devlog/2025-11-20_inngest-integration.md
related_issues: [#49, BD-042]
---

Writing Guidelines

1. Brief summary: 1-3 sentences, what changed and why it matters
2. User-facing: Focus on impact, not implementation details
3. Optional details: Add bullet points for complex changes

Browsing Fragments

# List all fragments chronologically
ls -1 docs/changelog/

# Find fragments about a topic
grep -l "oauth" docs/changelog/*.md

# See all fragments of a type
grep "^type: feature" docs/changelog/*.md

Creating a Fragment

Treat requests like these as direct triggers for this skill:

• "Create a changelog fragment for this work"
• "Document this completed change"
• "Add a changelog entry for OAuth token refresh"

Skill Activation

This skill activates when:

• Completing implementation work
• Writing session documentation for completed work
• Landing changes that should be documented
