@repo-prism/intelligence

Stack detection SPI, Repository DNA, health, and insights.

Implemented: M-040 (Stack Detector SPI) · M-013 (multi-domain detector packs + assembleDnaReport)
Depends on: @repo-prism/shared, @repo-prism/graph-engine
Surfaces: via @repo-prism/core only (ADR-0004 / ADR-0007)

Default packs: createDefaultDetectorPacks() — FE/BE/Mobile/Desktop/Data-ML-AI/Data-eng/DevOps/Embedded/Game/Tooling (local manifests only).

StackDetector SPI

| Member | Role | |---|---| | id | Stable detector id | | spiVersion | Must be in host range (currently 1) | | domains | Domains this detector may emit | | personaHints | Personas it may suggest | | detect(ctx) | → additive StackSignal[] |

Well-known domain / persona ids: StackDomain / DeveloperPersona in @repo-prism/shared (open string registry).

Stubs (M-040)

• unknown — emits nothing
• nodejs-manifest — package.json → low-confidence tooling signal
