goose (the AAIF agent) discovers MCP extensions from its config, and reads AGENTS.md natively — so nika init in the repo teaches it the language with zero extra wiring. The binary install is the prerequisite (brew install supernovae-st/tap/nika or a release tarball · other paths). Wiring is manual — nika wire has no goose target. Add the oracle as a stdio extension in goose’s config: 
extensions:
  nika:
    cmd: nika
    args: [mcp]
    enabled: true
    type: stdio

The repo side

nika init
AGENTS.md, rules and the repo skill land at the repo root — the agent-teaching surface that makes the oracle useful. goose picks up AGENTS.md on its own.

goose’s extension list shows nika with the eight nika_* tools (the oracle’s contract: validate, explain, schema, cost — no execution, no mutation). Then prove the loop end-to-end: integrate in 10 minutes.
