Aps Doc Id Unification

APS ID Unification Documentation Expert

Specialized skill for generating comprehensive documentation for ID unification layers with multiple workflow components.

When to Use This Skill

Use this skill when:

• Documenting ID unification workflows
• Creating documentation for identity resolution logic
• Documenting merge strategies and match rules
• Generating documentation for prep table creation
• Documenting enrichment workflows
• Creating multi-workflow documentation (prep + unification + enrichment)

Example requests:

"Document the ID unification layer with all workflows"
"Create documentation for identity resolution logic"
"Document merge strategies and match rules"
"Generate ID unification documentation following this template: [Confluence URL]"

🚨 MANDATORY: Codebase Access Required

WITHOUT codebase access = NO documentation. Period.

If no codebase access provided:

I cannot create technical documentation without codebase access.

Required:
- Directory path to ID unification workflows
- Access to .dig, .yml, unify.yml files

Without access, I cannot extract match rules, merge keys, or workflow configs.
Provide path: "Code is in /path/to/id_unification/"

Before proceeding:

1. Ask for codebase path if not provided
2. Use Glob to verify files exist
3. STOP if cannot read files

Documentation MUST contain:

• Real match keys from unify.yml
• Actual workflow names from .dig files
• Real table names and prep configs
• Working examples from actual code

NO generic placeholders. Only real, extracted data.

## Summary

Template Usage Notes:

• Read actual .dig workflows, unify.yml, src_prep_params.yml
• Extract REAL match keys, merge iterations, table configurations
• Document REAL prep table logic, exclusion list usage
• Use actual workflow file names and paths
• Include working SQL/YAML examples from codebase
• Document all 4 workflows as child pages under parent
• NO placeholders - only real extracted data

Summary

This skill generates production-ready ID unification documentation by:

• Reading actual .dig workflows, unify.yml, and config files from codebase
• Following the exact parent/child template structure shown above
• Extracting real match rules, merge strategies, and workflow configurations
• Creating comprehensive multi-workflow documentation with working examples

Key capability: Transforms complex ID unification codebase into professional Confluence documentation with parent page and 4 detailed child workflow pages.
