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:

Fact Type	Example
Brand name	"COFFEE TO"
Tagline	"Coffee to, begin."
Address	2-XX-XX Kamimeguro, Meguro-ku, Tokyo
Business hours	8:00 - 20:00
Opening date	2026.4.1
Menu prices	Drip Coffee ¥500
Instagram handle	@coffee.to.nakameguro
Color HEX values	#2D1B0E, #F5E6D3

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

Pattern	Cause	Fix
Website brand name differs from brand guide	Dev started website before brand design was complete	Create correction task for dev
Poster prices differ from financial pricing	Marketing and finance worked independently	Defer to finance, fix the poster
Social media dates differ from poster dates	Same agent produced outputs at different times	Unify to the latest confirmed date

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
