Skill-Stack Matrix
Maps stack identifiers to the skills that serve them.
Used by resolve_skills.py to determine what to load.

Matrix Format
Each entry:
- Stack IDs: which detected stacks trigger this skill
- Skill: skill name (matches directory name in /mnt/skills/)
- Priority Base: starting priority before signal boosts
- Required: must-load if stack detected, vs nice-to-have
- Companions: skills that should co-load
- Conflicts: skills that should not co-load

Path Pattern |

| xlsx |

/mnt/skills/public/xlsx/ |
Note: document skills are demand-loaded, not stack-loaded. They activate on user
request ("make a presentation") not on repo content. The router keeps them in a
"standby" pool -- not loaded into context, but available for instant load.

Companion Rules
When skill A is loaded, also load skill B if its stack is detected:
| Primary Skill |
Companion |
Condition |
| fastapi |
sqlalchemy |
DB migrations detected |
| fastapi |
openapi |
OpenAPI spec file exists |
| django |
django-orm |
(always with django) |
| react |
tailwind |
tailwind.config.* exists |
| docker |
docker-compose |
docker-compose.yml exists |
| kubernetes |
helm |
Chart.yaml exists |
| terraform |
aws |
provider "aws" in *.tf |
| langchain |
openai-sdk |
openai in deps |
| pytest |
coverage |
.coveragerc or coverage config exists |
Conflict Rules
These skills should not be co-loaded (pick the one with higher confidence/priority):
| Skill A |
Skill B |
Resolution |
| flask |
fastapi |
Higher confidence wins |
| flask |
django |
Higher confidence wins |
| jest |
vitest |
Higher confidence wins |
| webpack |
vite |
Higher confidence wins |
| npm |
yarn |
Check lock file |
| npm |
pnpm |
Check lock file |
| yarn |
pnpm |
Check lock file |
| react |
vue |
Both can coexist in monorepo |
| sqlalchemy |
prisma |
Both can coexist if different services |
Conflict resolution: check if the repo is a monorepo. In monorepos, "conflicting"
skills may serve different packages and should both load. In single-package repos,
pick the one with higher confidence.
