Document Review System Design

Overview

Add two new review stages to the superpowers workflow:

1. Spec Document Review - After brainstorming, before writing-plans
2. Plan Document Review - After writing-plans, before implementation

Both follow the iterative loop pattern used by implementation reviews.

Spec Document Reviewer

Purpose: Verify the spec is complete, consistent, and ready for implementation planning.

Location: skills/brainstorming/spec-document-reviewer-prompt.md

What it checks for:

Category	What to Look For
Completeness	TODOs, placeholders, "TBD", incomplete sections
Coverage	Missing error handling, edge cases, integration points
Consistency	Internal contradictions, conflicting requirements
Clarity	Ambiguous requirements
YAGNI	Unrequested features, over-engineering

Output format:

## Spec Review

**Status:** Approved | Issues Found

**Issues (if any):**
- [Section X]: [issue] - [why it matters]

**Recommendations (advisory):**
- [suggestions that don't block approval]

Review loop: Issues found -> brainstorming agent fixes -> re-review -> repeat until approved.

Dispatch mechanism: Use the Task tool with subagent_type: general-purpose. The reviewer prompt template provides the full prompt. The brainstorming skill's controller dispatches the reviewer.

Plan Document Reviewer

Purpose: Verify the plan is complete, matches the spec, and has proper task decomposition.

Location: skills/writing-plans/plan-document-reviewer-prompt.md

What it checks for:

Category	What to Look For
Completeness	TODOs, placeholders, incomplete tasks
Spec Alignment	Plan covers spec requirements, no scope creep
Task Decomposition	Tasks atomic, clear boundaries
Task Syntax	Checkbox syntax on tasks and steps
Chunk Size	Each chunk under 1000 lines

Chunk definition: A chunk is a logical grouping of tasks within the plan document, delimited by ## Chunk N: <name> headings. The writing-plans skill creates these boundaries based on logical phases (e.g., "Foundation", "Core Features", "Integration"). Each chunk should be self-contained enough to review independently.

Spec alignment verification: The reviewer receives both:

1. The plan document (or current chunk)
2. The path to the spec document for reference

The reviewer reads both and compares requirements coverage.

Output format: Same as spec reviewer, but scoped to the current chunk.

Review process (chunk-by-chunk):

1. Writing-plans creates chunk N
2. Controller dispatches plan-document-reviewer with chunk N content and spec path
3. Reviewer reads chunk and spec, returns verdict
4. If issues: writing-plans agent fixes chunk N, goto step 2
5. If approved: proceed to chunk N+1
6. Repeat until all chunks approved

Dispatch mechanism: Same as spec reviewer - Task tool with subagent_type: general-purpose.

Updated Workflow

brainstorming -> spec -> SPEC REVIEW LOOP -> writing-plans -> plan -> PLAN REVIEW LOOP -> implementation

Spec Review Loop:

1. Spec complete
2. Dispatch reviewer
3. If issues: fix -> goto 2
4. If approved: proceed

Plan Review Loop:

1. Chunk N complete
2. Dispatch reviewer for chunk N
3. If issues: fix -> goto 2
4. If approved: next chunk or implementation

Markdown Task Syntax

Tasks and steps use checkbox syntax:

- [ ] ### Task 1: Name

- [ ] **Step 1:** Description
  - File: path
  - Command: cmd

Error Handling

Review loop termination:

• No hard iteration limit - loops continue until reviewer approves
• If loop exceeds 5 iterations, the controller should surface this to the human for guidance
• The human can choose to: continue iterating, approve with known issues, or abort

Disagreement handling:

• Reviewers are advisory - they flag issues but don't block
• If the agent believes reviewer feedback is incorrect, it should explain why in its fix
• If disagreement persists after 3 iterations on the same issue, surface to human

Malformed reviewer output:

• Controller should validate reviewer output has required fields (Status, Issues if applicable)
• If malformed, re-dispatch reviewer with a note about expected format
• After 2 malformed responses, surface to human

Files to Change

New files:

• skills/brainstorming/spec-document-reviewer-prompt.md
• skills/writing-plans/plan-document-reviewer-prompt.md

Modified files:

• skills/brainstorming/SKILL.md - add review loop after spec written
• skills/writing-plans/SKILL.md - add chunk-by-chunk review loop, update task syntax examples
