Cross Validation

Output Consistency Validation

When to Execute

After wanman task list shows all tasks with status=done, perform output consistency validation before inspecting artifact data.

Validation Process

Step 1: Collect All Output Files

# List all agent output files
find /workspace/agents -name "*.md" -o -name "*.html" | grep -v CLAUDE.md | sort

Step 2: Extract Key Facts

Extract the following key information from each file:

Step 3: Compare for Consistency

Cross-check file by file:

Brand guide (marketing) brand name  ←→  Website (dev) brand name
Brand guide tagline                 ←→  Poster (marketing) tagline
Brand guide colors                  ←→  Website CSS colors
Financial report pricing            ←→  Website menu prices
Poster opening date                 ←→  Social media content date
Poster address                      ←→  Website address

Step 4: Handle Inconsistencies

When inconsistencies are found, defer to the earliest completed authoritative document (usually the brand guide) and create a correction task:

# Example: website brand name does not match brand guide
wanman task create "Fix website brand name: unify the brand name on the website from 'KAWA' to 'COFFEE TO' as specified in the brand guide. Update all brand names, taglines, and Instagram handles in index.html. Reference: /workspace/agents/output/marketing/brand-design.md" --assign dev --priority 1

Authoritative Document Priority

When information conflicts, follow this order of precedence:

1. Brand guide — Brand name, tagline, visual style
2. Financial report — Prices, cost data
3. Market research — Competitor data, market data
4. Website/posters — Must align with the above (not a source of truth)

Common Inconsistency Patterns

Preventive Measures

When creating tasks, use --after to declare dependencies:

# Brand design must be completed first
brand_id=$(wanman task create "Brand design" --assign marketing --priority 1 | grep -o '[a-f0-9-]\{36\}')

# Website development depends on brand design
wanman task create "Website development: based on the brand guide..." --assign dev --priority 5 --after $brand_id

# Poster design also depends on brand design
wanman task create "Opening poster: based on the brand guide..." --assign marketing --priority 4 --after $brand_id
