Create Implementation Plan

Generate a detailed implementation plan based on existing analysis or concept documents.

Instructions

1. Detect Current Context

   • Check current git branch to determine workflow folder
   • Branch feature/42-something → look for workflows/issue-42-*/
   • Branch feature/my-feature → look for workflows/feature-my-feature/

2. Find Source Document

   • Look for analysis.md (from /analyze-issue) or concept.md (for features)
   • If not found, ask user to run /analyze-issue first or provide context

3. Read Project Guidelines

   • Review CODING_GUIDELINES.md for implementation standards
   • Review TESTING_GUIDELINES.md for test requirements
   • Review COMMIT_GUIDELINES.md for commit structure

4. Create Implementation Plan

   • Write plan.md in the same workflow folder
   • Break down into specific, actionable tasks
   • Include file paths and specific changes
   • Add test plan based on TESTING_GUIDELINES.md

Plan Template

Write to workflows/<folder>/plan.md:

# Implementation Plan: <branch-name>

## Source
- Issue: #<number> (<link>)
- Analysis: `workflows/<folder>/analysis.md`

## Overview
<Brief summary of what will be implemented>

## Prerequisites
- [ ] Feature branch created: `feature/<name>`
- [ ] Analysis reviewed and understood
- [ ] No blocking questions remain

## Implementation Tasks

### Task 1: <Name>
**Files**: `path/to/file.go`

**Changes**:
- [ ] <Specific change 1>
- [ ] <Specific change 2>

**Details**:
<Any additional context or code snippets>

### Task 2: <Name>
**Files**: `path/to/file1.go`, `path/to/file2.go`

**Changes**:
- [ ] <Specific change>

**Depends on**: Task 1

### Task 3: Add Tests
**Files**: `test/cmd/<file>_test.go`

**Changes**:
- [ ] Add `Test<FunctionName>` - <what it tests>
- [ ] Add `Test<FunctionName>WithError` - <error case>

**Test Requirements** (per TESTING_GUIDELINES.md):
- One test case per function
- Structured comments with Steps
- Use testutil helpers, not os.Chdir

## Test Plan

### Unit Tests
| Test Name | Purpose | File |
|-----------|---------|------|
| `TestXxx` | <purpose> | `test/...` |

### Integration Tests
| Test Name | Scenario | File |
|-----------|----------|------|
| `TestXxxCommand` | <scenario> | `test/cmd/...` |

## Documentation Updates
- [ ] `docs/<command>.1.md` - <changes needed>
- [ ] `docs/gitflow-config.5.md` - <if config changes>
- [ ] Command help text updates

## Checkpoints

After each checkpoint, verify:
1. `go build ./...` succeeds
2. `go test ./...` passes
3. Changes work as expected

| Checkpoint | After Task | Verification |
|------------|------------|--------------|
| 1 | Task 1 | <what should work> |
| 2 | Task 2 | <what should work> |
| 3 | Task 3 | All tests pass |

## Commit Strategy

Following COMMIT_GUIDELINES.md, plan these commits:
1. `<type>(<scope>): <description>` - <what's included>
2. `test(<scope>): <description>` - test additions
3. `docs(<scope>): <description>` - documentation updates

## Estimated Scope
- Files to modify: <count>
- New files: <count>
- Tests to add: <count>

5. Validate Plan

   • Ensure all affected files from analysis are covered
   • Verify test plan aligns with TESTING_GUIDELINES.md
   • Check documentation requirements

6. Report Completion

   • Show path to created plan
   • Suggest next step: /validate-tests to verify test approach, then start implementing
