Verifying Layer Documentation

Purpose: Detect gaps between documentation and source code. Output is a work list for the next skill to fix.

Output: docs/unwind/layers/{layer}/gaps.md - list of missing items only

Does NOT:

• Write about what's correct
• Assign scores
• Apply fixes (that's the next skill's job)

Process

For each layer, compare documentation against source and output ONLY the gaps.

Step 1: Read Documentation

CopyRead docs/unwind/layers/{layer}/index.md
Follow links to all section files
Build list of documented items

Step 2: Read Source

CopyRead source files for the layer (from architecture.md entry_points)
Build list of actual items in code

Step 3: Find Gaps

Compare the two lists:

• Items in source but NOT in documentation → MISSING
• Items documented incorrectly → INACCURATE

Note: All items should already have [MUST/SHOULD/DON'T] tags (see analysis-principles.md section 9). If items lack tags, that indicates the analysis skill was not followed correctly - not a verification gap.

Step 4: Write gaps.md

Write ONLY the gaps to docs/unwind/layers/{layer}/gaps.md

Output Format

Copy# {Layer} Documentation Gaps

## Missing Items

### {item_name}
- **Type:** table|service|endpoint|entity|etc
- **Location:** {source_file}:{line_start}-{line_end}
- **Category:** MUST|SHOULD|DON'T
- **Section:** {which section file it belongs in}

### {next_item}
...

## Inaccuracies

### {item_name}
- **Location:** {source_file}:{lines}
- **Issue:** {what's wrong}
- **Actual:** {what code shows}

Example gaps.md

Copy# Database Documentation Gaps

## Missing Items

### audit_logs table
- **Type:** table
- **Location:** src/schema.ts:412-445
- **Category:** SHOULD
- **Section:** schema.md

### user_sessions table
- **Type:** table
- **Location:** src/schema.ts:450-478
- **Category:** MUST
- **Section:** schema.md

### settings JSONB schema
- **Type:** jsonb_schema
- **Location:** src/schema.ts:89 (organisation.settings)
- **Category:** MUST
- **Section:** jsonb-schemas.md

## Inaccuracies

### users.status column
- **Location:** src/schema.ts:45
- **Issue:** Wrong type documented
- **Actual:** enum('active', 'suspended', 'deleted') not varchar

Agent Dispatch

For each layer, dispatch verification in parallel:

CopyTask(subagent_type="general-purpose")
  description: "Find gaps in [layer] documentation"
  prompt: |
    Compare docs/unwind/layers/{layer}/ against source code.

    Entry points: [from architecture.md]
    Link format: [from architecture.md]

    Output ONLY gaps to docs/unwind/layers/{layer}/gaps.md

    DO NOT:
    - Write about what's correct
    - Assign scores
    - Fix anything

    ONLY list:
    - Missing items (with source location, category, target section)
    - Inaccuracies (with what's wrong and actual value)

Layer-Specific Gap Detection

Database Layer

• Missing tables
• Missing columns
• Missing JSONB schemas
• Missing indexes
• Missing FK relationships

Service Layer

• Missing services
• Missing formulas
• Missing edge cases
• Missing constants

API Layer

• Missing endpoints
• Missing route files
• Missing permission documentation
• Missing error responses

Domain Model

• Missing entities
• Missing enums
• Missing validation rules
• Missing state transitions

Frontend Layer

• Missing pages
• Missing user flows
• Missing permission gates

Next Step

After gaps.md files are created, run completing-layer-documentation to fix all gaps.
