langgraph-cli[inmem] is declared as a hard runtime dependency in [project.dependencies], but nothing under src/skillspector/ imports it. Its
only consumers in the repo are the make langgraph-dev target and langgraph.json, both of which are developer tooling for LangGraph Studio.
Because it is a runtime dependency, every install of the skillspector CLI — including ones that never run the dev server — pulls in the full LangGraph API server stack.
Impact
langgraph-cli[inmem] resolves to langgraph-api + langgraph-runtime-inmem.
langgraph-api alone requires:
grpcio, grpcio-tools, grpcio-health-checking, opentelemetry-api, opentelemetry-sdk, opentelemetry-exporter-otlp-proto-http, opentelemetry-exporter-prometheus, uvicorn, starlette, sse-starlette, structlog, cloudpickle, croniter, watchfiles
None of these dependencies seem to be required in a production build.
Suggested Fix
Move it to an optional extra, so the dev-server workflow keeps working while a plain install stays lean:
[project.optional-dependencies]
studio = [
"langgraph-cli[inmem]>=0.4.14",
]
dev = [
"skillspector[mcp]",
"skillspector[studio]",
...
]If I'm missing anything here, please let me know.
