KEY FINDINGS SUMMARY
================================================================================

Current State (nexus-agents):
✓ Task-aware expert selection (analyzes requirements first)
✓ Multi-factor scoring (0.4 capability + 0.4 domain + 0.2 weight)
✓ Configurable custom experts from nexus-agents.yaml
✓ Deterministic, debuggable routing algorithm
✓ Well-designed for 5-20 expert pools

Improvement Opportunities Identified:
⚠ No formal skill dependency graph
⚠ Exact capability matching (no semantic similarity)
⚠ No capability gap reporting
⚠ Flat role structure (no seniority levels)
⚠ No capability documentation

Five Prioritized Recommendations:

P1: Skill Dependency Graph (HIGH)
   - Status: Not implemented
   - Value: High | Effort: Medium | Risk: Low
   - Timeline: 2 weeks
   - Enables: P2, P3, composite task support

P2: Semantic Capability Matching (MEDIUM)
   - Status: Not implemented
   - Value: Medium | Effort: Medium | Risk: Low
   - Timeline: 2 weeks
   - Handles: Non-standard terminology, synonyms

P3: Capability Gap Detection (MEDIUM)
   - Status: Not implemented
   - Value: Medium | Effort: Low | Risk: None
   - Timeline: 1 week
   - Improves: User feedback, unmet capability visibility

P4: Role Hierarchy (LOW)
   - Status: Not implemented
   - Value: Low | Effort: Medium | Risk: Medium
   - Timeline: 2 weeks
   - Enables: Team composition, seniority-aware selection

P5: Capability Documentation (LOW)
   - Status: Not implemented
   - Value: Low | Effort: Low | Risk: None
   - Timeline: 1 week
   - Improves: Discoverability, custom expert guidance

Implementation Timeline:
MVP (P1 + P2): 4 weeks, 1-2 developers
Full (All P1-P5): 8 weeks, 1-2 developers
