Changelog-Update Skill

Update CHANGELOG.md with business-focused entries by systematically reviewing file changes.

Note: For automated release notes from conventional commits, use the release-notes skill instead.

When to Use

• During development: Document feature/fix for users before PR/merge

• PR preparation: Add business-focused entry to CHANGELOG.md

• Manual documentation: When commits don't capture full business impact

Don't use for releases: Use release-notes skill to generate versioned release docs.

Pre-Execution Checklist

Find existing CHANGELOG.md location

• Check root: ./CHANGELOG.md (preferred)

• Fallback: ./docs/CHANGELOG.md

• If not found: Create at root

Read current changelog to understand format and last entries

Workflow

Step 1: Gather Changes

Determine change scope:

• PR-based: git diff origin/develop...HEAD --name-only

• Branch-based: git log origin/develop..HEAD --oneline

• Commit-based: git show {commit} --name-only

Step 2: Create Temp Notes File

Create .ai/workspace/changelog-notes-{YYMMDD-HHMM}.md :

Changelog Review Notes - {date}

Files Changed

• file1.ts -
• file2.cs -

Categories

Added (new features)

Changed (modifications to existing)

Fixed (bug fixes)

Deprecated

Removed

Security

Business Summary

<!-- What does this mean for users? -->

Step 3: Systematic File Review

For each changed file:

• Read file or diff

• Identify business impact (not just technical change)

• Check box and note in temp file

• Categorize into appropriate section

Business Focus Guidelines:

• ❌ "Added StageCategory enum"

• ✅ "Added stage categories (Sourced, Applied, Interviewing, etc.) for pipeline tracking"

• ❌ "Created PipelineController.cs "

• ✅ "Added API endpoints for pipeline management"

Step 4: Holistic Review

Read temp notes file completely. Ask:

• What's the main feature/fix?

• Who benefits and how?

• What can users now do that they couldn't before?

Step 5: Generate Changelog Entry

Format (Keep a Changelog):

[Unreleased]

{Feature/Module Name}: {Feature Title}

Feature/Fix: {One-line business description}

Added

• {Business-focused item}

Changed

• {What behavior changed}

Fixed

• {What issue was resolved}

Step 6: Update Changelog

• Read existing CHANGELOG.md

• Insert new entry under [Unreleased] section

• If no [Unreleased] section, create it after the header

Step 7: Cleanup

Delete temp notes file: .ai/workspace/changelog-notes-*.md

Examples

Good Entry

bravoTALENTS: Hiring Process Management

Feature: Customizable hiring process/pipeline management for recruitment workflows.

Added

• Drag-and-drop pipeline stage builder with default templates
• Stage categories (Sourced, Applied, Interviewing, Offered, Hired, Rejected)
• Pipeline duplication for quick setup
• Multi-language stage names (EN/VI)

Bad Entry (Too Technical)

Pipeline Changes

Added

• Pipeline.cs entity
• StageCategory enum
• PipelineController
• SavePipelineCommand

Anti-Patterns

• ❌ Creating new changelog in docs/ when root exists

• ❌ Skipping file review (leads to missed changes)

• ❌ Technical jargon without business context

• ❌ Forgetting to delete temp notes file

• ❌ Not using [Unreleased] section
