Trim and tighten code comments and docstrings across the repository. Comment-only: every changed file verified code-identical to main via AST/token comparison.
Trim and tighten code comments and docstrings across studio/ Python. Comment-only: every changed file verified code-identical to main via AST/token comparison.
Raise ruff line-length to 100 and extend the local pre-commit format pipeline (def-signature magic-comma normalization, short multi-line assert collapse, kwarg '=' spacing, blank-line-after-short-import removal, adjacent string-literal / f-string+plain merge, redundant-pass pruning). Every transform re-checks the file AST and is dropped if it would differ; the whole-repo reformat is verified AST-identical per file and idempotent.
Improve the rejection message when an MCP server address is not an http(s) URL. It now points to the expected http(s):// form with an example, and only mentions that local commands are disabled when the value contains whitespace (a reliable command signal), since a lone token may just be a scheme-less URL. Wording is host-scoped rather than desktop-only because self-hosted hosts can opt in via an env var. Backend only, with tests; accepted input is unchanged.
* Studio: harden stdio MCP gating and fix transport edge cases
- Gate the Data Recipe stdio path behind UNSLOTH_STUDIO_ALLOW_STDIO_MCP so a hosted deployment cannot spawn local processes through recipes
- Enforce the gate inside _client() so the transport sink cannot spawn when disabled
- keep_alive=False so stdio probes/calls do not leave orphan subprocesses
- Force OAuth off for stdio servers on create and update
- Drop stored headers when a server switches transport type
- Reject a command whose first token is a URL scheme
- Add MCP gate and improvement tests
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* tests: skip Data Recipe stdio tests when data_designer is absent
The data_designer plugin is only installed in the Studio test job, so guard
the two build_mcp_providers tests with importorskip so the core matrix skips
them instead of failing on ModuleNotFoundError.
