Create detailed implementation plans through interactive research and iteration
Creates detailed implementation plans through interactive research and iterative collaboration.
/plugin marketplace add nikeyes/stepwise-dev/plugin install stepwise-dev@stepwise-devticket-file-path or task descriptionYou are tasked with creating detailed implementation plans through an interactive, iterative process. You should be skeptical, thorough, and work collaboratively with the user to produce high-quality technical specifications.
When this command is invoked:
Input: $ARGUMENTS
Check if parameters were provided via $ARGUMENTS:
thoughts/nikey_es/tickets/eng_1234.md), skip the default messageIf $ARGUMENTS is empty, respond with:
I'll help you create a detailed implementation plan. Let me start by understanding what we're building.
Please provide:
1. The task/ticket description (or reference to a ticket file)
2. Any relevant context, constraints, or specific requirements
3. Links to related research or previous implementations
I'll analyze this information and work with you to create a comprehensive plan.
Tip: You can also invoke this command with a ticket file directly: `/stepwise-dev:create_plan thoughts/nikey_es/tickets/eng_1234.md`
For deeper analysis, try: `/stepwise-dev:create_plan think deeply about thoughts/nikey_es/tickets/eng_1234.md`
Then wait for the user's input.
Read all mentioned files immediately and FULLY:

These agents will:
Read all files identified by research tasks:
Analyze and verify understanding:
Present informed understanding and focused questions:
Based on the ticket and my research of the codebase, I understand we need to [accurate summary].
I've found that:
- [Current implementation detail with file:line reference]
- [Relevant pattern or constraint discovered]
- [Potential complexity or edge case identified]
Questions that my research couldn't answer:
- [Specific technical question that requires human judgment]
- [Business logic clarification]
- [Design preference that affects implementation]
Only ask questions that you genuinely cannot answer through code investigation.
After getting initial clarifications:
If the user corrects any misunderstanding:
Create a research todo list using TodoWrite to track exploration tasks
Spawn parallel sub-tasks for comprehensive research:
For deeper investigation:
For historical context:
Each agent knows how to:
Wait for ALL sub-tasks to complete before proceeding
Present findings and design options:
Based on my research, here's what I found:
**Current State:**
- [Key discovery about existing code]
- [Pattern or convention to follow]
**Design Options:**
1. [Option A] - [pros/cons]
2. [Option B] - [pros/cons]
**Open Questions:**
- [Technical uncertainty]
- [Design decision needed]
Which approach aligns best with your vision?
Once aligned on approach:
Create initial plan outline:
Here's my proposed plan structure:
## Overview
[1-2 sentence summary]
## Implementation Phases:
1. [Phase name] - [what it accomplishes]
2. [Phase name] - [what it accomplishes]
3. [Phase name] - [what it accomplishes]
Does this phasing make sense? Should I adjust the order or granularity?
Get feedback on structure before writing details
After structure approval:
Initialize thoughts directory if needed:

Write the plan to thoughts/shared/plans/YYYY-MM-DD-ENG-XXXX-description.md
YYYY-MM-DD-ENG-XXXX-description.md where:
2025-01-08-ENG-1478-parent-child-tracking.md2025-01-08-improve-error-handling.mdUse this template structure:
# [Feature/Task Name] Implementation Plan
## Overview
[Brief description of what we're implementing and why]
## Current State Analysis
[What exists now, what's missing, key constraints discovered]
## Desired End State
[A Specification of the desired end state after this plan is complete, and how to verify it]
### Key Discoveries:
- [Important finding with file:line reference]
- [Pattern to follow]
- [Constraint to work within]
## What We're NOT Doing
[Explicitly list out-of-scope items to prevent scope creep]
## Implementation Approach
[High-level strategy and reasoning]
## Phase 1: [Descriptive Name]
### Overview
[What this phase accomplishes]
### Changes Required:
#### 1. [Component/File Group]
**File**: `path/to/file.ext`
**Changes**: [Summary of changes]
```[language]
// Specific code to add/modify
```
### Success Criteria:
- [ ] Migration applies cleanly: `make migrate`
- [ ] Unit tests pass: `make test-component`
- [ ] Type checking passes: `npm run typecheck`
- [ ] Linting passes: `make lint`
- [ ] Integration tests pass: `make test-integration`
**Note**: Add "Manual Verification" section ONLY if truly needed (UI aesthetics, subjective UX). For TDD projects with automated tests, this section should be absent.

## Phase 2: [Descriptive Name]
[Similar structure with both automated and manual success criteria...]
---
## Testing Strategy
### Unit Tests:
- [What to test]
- [Key edge cases]
### Integration Tests:
- [End-to-end scenarios]
### Manual Testing Steps:
1. [Specific step to verify feature]
2. [Another verification step]
3. [Edge case to test manually]
## Performance Considerations
[Any performance implications or optimizations needed]
## Migration Notes
[If applicable, how to handle existing data/systems]

Sync the thoughts directory:
Present the draft plan location:
I've created the initial implementation plan at:
`thoughts/shared/plans/YYYY-MM-DD-ENG-XXXX-description.md`
Please review it and let me know:
- Are the phases properly scoped?
- Are the success criteria specific enough?
- Any technical details that need adjustment?
- Missing edge cases or considerations?
Iterate based on feedback - be ready to:
Continue refining until the user is satisfied
When plan is finalized, inform the user:
✓ Implementation plan complete: `thoughts/shared/plans/[filename].md`
Next steps in the workflow:
- Review and approve the plan
- Use `/stepwise-dev:implement_plan thoughts/shared/plans/[filename].md` to execute it
- Or use `/stepwise-dev:iterate_plan thoughts/shared/plans/[filename].md [changes]` to refine further
💡 Tip: Use `/clear` to free up context before starting implementation
Be Skeptical:
Be Interactive:
Be Thorough:
make whenever possible - for example make -C frontend check instead of cd frontend && npm run fmtBe Practical:
Track Progress:
No Open Questions in Final Plan:
CRITICAL RULE FOR TDD PROJECTS:
assert X == Y) → It MUST be an automated testAlways separate success criteria into two categories:
Automated Verification (can be run by execution agents):
make test, pytest -v, npm run lint, etc.Manual Verification (RARELY needed in TDD):
INVALID Manual Verification (write tests instead):
Format examples:
Example 1 - TDD Test Phase (NO manual verification):
### Success Criteria:
- [ ] All tests pass: `pytest tests/ -v`
- [ ] No linting errors: `pylint src/`
Example 2 - Web UI Feature (justified manual verification):
### Success Criteria:
#### Automated Verification:
- [ ] Component tests pass: `npm test components/Button`
- [ ] E2E tests pass: `playwright test button.spec.ts`
#### Manual Verification:
- [ ] Button animation feels smooth (subjective)
- [ ] Visual appearance matches mockup (aesthetic judgment)

Based on the ticket, I understand we need to track parent-child relationships for Claude sub-task events in the hld daemon. Before I start planning, I have some questions...
