Relationship to NENE2

Roles

Repository	Responsibility
NENE2	PHP runtime, OpenAPI authoring, MCP catalog
nene2-js	TypeScript consumer SDK
nene2-python	Python parity port
nene-mcp	PHP stdio MCP (separate from this client)

Contract flow

1. NENE2 changes docs/openapi/openapi.yaml.
2. nene2-js syncs contracts/openapi.yaml and regenerates types.
3. Apps upgrade @hideyukimori/nene2-client when ready.

OpenAPI wins — if the server matches the contract, fix the client; if the server diverges, fix the server or the contract in NENE2 first.

What not to copy here

• PHP src/, migrations, Compose for the PHP app
• MCP stdio server implementation
• Application domain logic
