Create ToolUniverse Skill

Systematic workflow for creating production-ready ToolUniverse skills.

Core Principles

Build on the 10 pillars from devtu-optimize-skills:

1. TEST FIRST - never document untested tools
2. Verify tool contracts - don't trust function names
3. Handle SOAP tools - add operation parameter
4. Implementation-agnostic docs - no Python/MCP code in SKILL.md
5. Foundation first - query aggregators before specialized tools
6. Disambiguate carefully - resolve IDs properly
7. Implement fallbacks - Primary -> Fallback -> Default
8. Grade evidence - T1-T4 tiers on claims
9. Quantified completeness - numeric minimums per section
10. Synthesize - models and hypotheses, not just lists

See OPTIMIZE_INTEGRATION.md for detailed application of each pillar.
