Follow GF(3) conservation across triads
Have deterministic Gay.jl colors assigned
Maintain role consistency (GAY/MASTER/SLAVE)

Validation Rules

Rule 1: Skill Structure

Every skill must have:

skills/<skill-name>/
├── SKILL.md           # Required
├── *.py|*.rb|*.jl     # Implementation (optional)
└── tests/             # Validation tests (optional)

Rule 2: GF(3) Triad Declaration

Skills should declare their triad membership:

## GF(3) Triad

| Role | Skill | Trit |
|------|-------|------|
| GAY (+1) | skill-a | +1 |
| MASTER (0) | skill-b | 0 |
| SLAVE (-1) | skill-c | -1 |

Sum: (+1) + (0) + (-1) = 0 ✓

Rule 3: Color Assignment

Colors must be deterministic via Gay.jl:

from gay_mcp import color_at

# Verify skill color
assert color_at(seed=2025, index=8)['hex'] == '#4857D5'
