[IMPORTANT] Use

TaskCreate

to break ALL work into small tasks BEFORE starting — including tasks for each file read. This prevents context loss from long files. For simple tasks, AI MUST ATTENTION ask user whether to skip.

External Memory: For complex or lengthy work (research, analysis, scan, review), write intermediate findings and final results to a report file in

plans/reports/

— prevents context loss and serves as deliverable.

Evidence Gate: MANDATORY IMPORTANT MUST ATTENTION — every claim, finding, and recommendation requires

file:line

proof or traced evidence with confidence percentage (>80% to act, <80% must verify first).

Critical Thinking Mindset — Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence >80% to act. Anti-hallucination: Never present guess as fact — cite sources for every claim, admit uncertainty freely, self-check output for errors, cross-reference independently, stay skeptical of own confidence — certainty without evidence root of all hallucination.

AI Mistake Prevention — Failure modes to avoid on every task:

• Check downstream references before deleting. Deleting components causes documentation and code staleness cascades. Map all referencing files before removal.
• Verify AI-generated content against actual code. AI hallucinates APIs, class names, and method signatures. Always grep to confirm existence before documenting or referencing.
• Trace full dependency chain after edits. Changing a definition misses downstream variables and consumers derived from it. Always trace the full chain.
• Trace ALL code paths when verifying correctness. Confirming code exists is not confirming it executes. Always trace early exits, error branches, and conditional skips — not just happy path.
• When debugging, ask "whose responsibility?" before fixing. Trace whether bug is in caller (wrong data) or callee (wrong handling). Fix at responsible layer — never patch symptom site.
• Assume existing values are intentional — ask WHY before changing. Before changing any constant, limit, flag, or pattern: read comments, check git blame, examine surrounding code.
• Verify ALL affected outputs, not just the first. Changes touching multiple stacks require verifying EVERY output. One green check is not all green checks.
• Holistic-first debugging — resist nearest-attention trap. When investigating any failure, list EVERY precondition first (config, env vars, DB names, endpoints, DI registrations, data preconditions), then verify each against evidence before forming any code-layer hypothesis.
• Surgical changes — apply the diff test. Bug fix: every changed line must trace directly to the bug. Don't restyle or improve adjacent code. Enhancement task: implement improvements AND announce them explicitly.
• Surface ambiguity before coding — don't pick silently. If request has multiple interpretations, present each with effort estimate and ask. Never assume all-records, file-based, or more complex path.

Quick Summary

Goal: Generate business-focused changelog entries by systematically reviewing file changes.

Workflow:

1. Gather Changes — Get changed files via

   git diff

   (PR, commit, or range mode)
2. Create Temp Notes — Build categorized review notes (Added/Changed/Fixed/etc.)
3. Review Each File — Read diffs, identify business impact, categorize changes
4. Generate Entry — Write Keep-a-Changelog formatted entry under

   [Unreleased]

5. Cleanup — Delete temp notes file

Key Rules:

• Use business-focused language, not technical jargon (e.g., "Added pipeline management" not "Added PipelineController.cs")
• Group related changes by module/feature, not by file
• Always insert under the

  [Unreleased]

  section; create it if missing

Be skeptical. Apply critical thinking, sequential thinking. Every claim needs traced proof, confidence percentages (Idea should be more than 80%).

Changelog Skill

Generate business-focused changelog entries by systematically reviewing file changes.

Pre-Execution Checklist

1. Find existing CHANGELOG.md location

   • Check root:

     ./CHANGELOG.md

     (preferred)
   • Fallback:

     ./docs/CHANGELOG.md

   • If not found: Create at root

2. Read current changelog to understand format and last entries

Workflow

Step 1: Gather Changes

Determine change scope based on mode:

# PR/Branch-based (default)
git diff origin/develop...HEAD --name-only

# Commit-based
git show {commit} --name-only

# Range-based
git diff {from}..{to} --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:

1. Read file or diff
2. Identify business impact (not just technical change)
3. Check box and note in temp file
4. Categorize into appropriate section

Business Focus Guidelines:

StageCategory

PipelineController.cs

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]

### {Module}: {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

1. Read existing CHANGELOG.md
2. Insert new entry under

   [Unreleased]

   section
3. If no

   [Unreleased]

   section, create it after header
4. Preserve existing entries

Step 7: Cleanup

Delete temp notes file:

.ai/workspace/changelog-notes-*.md

Grouping Strategy

Group related changes by module/feature:

### Your Service: Hiring Process Management

**Feature**: Customizable hiring process/pipeline management.

#### Added

**Backend**:

- Entities: Pipeline, Stage, PipelineStage
- Controllers: PipelineController, StageController
- Commands: SavePipelineCommand, DeletePipelineCommand

**Frontend**:

- Pages: hiring-process-page
- Components: pipeline-filter, pipeline-stage-display

Anti-Patterns

1. ❌ Creating new changelog in docs/ when root exists
2. ❌ Skipping file review (leads to missed changes)
3. ❌ Technical jargon without business context
4. ❌ Forgetting to delete temp notes file
5. ❌ Not using [Unreleased] section
6. ❌ Listing every file instead of grouping by feature

Examples

Good Entry

### Your Service: 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)

#### Changed

- Candidate cards now show current pipeline stage
- Job creation wizard includes pipeline selection

Bad Entry (Too Technical)

### Pipeline Changes

#### Added

- Pipeline.cs entity
- StageCategory enum
- PipelineController
- SavePipelineCommand
- 20251216000000_MigrateDefaultStages migration

Workflow Recommendation

MANDATORY IMPORTANT MUST ATTENTION — NO EXCEPTIONS: If you are NOT already in a workflow, you MUST ATTENTION use

AskUserQuestion

to ask the user. Do NOT judge task complexity or decide this is "simple enough to skip" — the user decides whether to use a workflow, not you:

1. Activate

   feature

   workflow (Recommended) — scout → investigate → plan → cook → review → changelog
2. Execute

   /changelog

   directly — run this skill standalone

Next Steps

MANDATORY IMPORTANT MUST ATTENTION — NO EXCEPTIONS after completing this skill, you MUST ATTENTION use

AskUserQuestion

• "/test (Recommended)" — Run tests after changelog update
• "/docs-update" — Update docs if needed
• "Skip, continue manually" — user decides

Closing Reminders

MANDATORY IMPORTANT MUST ATTENTION break work into small todo tasks using

TaskCreate

AskUserQuestion

• MUST ATTENTION apply critical thinking — every claim needs traced proof, confidence >80% to act. Anti-hallucination: never present guess as fact. <!-- /SYNC:critical-thinking-mindset:reminder --> <!-- SYNC:ai-mistake-prevention:reminder -->
• MUST ATTENTION apply AI mistake prevention — holistic-first debugging, fix at responsible layer, surface ambiguity before coding, re-read files after compaction. <!-- /SYNC:ai-mistake-prevention:reminder -->
