The description runs about 2,800 characters, roughly 700 tokens, and lists when to use the tool in seven bullets without once saying when not to. Its parameter section uses snake_case names such as `total_thoughts` and `is_revision`, while the schema takes camelCase, and the README calls the tool `sequential_thinking` where the server registers `sequentialthinking`. The schema side is tidy. It has an output schema, required fields marked, integers with a minimum of 1, and annotations of readOnlyHint true and idempotentHint true (generous for a call that appends to history). The source defines errors as an object with an `error` field and a `status` of failed, with isError set, and nothing documents them. Three, because the schema is complete and annotated but the prose beside it names parameters the schema doesn't have. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.

Nothing from outside enters. No network, file or credential, and lib.ts is under 3 KB. The question is whether the scaffold earns its turns, since every thought is a round trip and about 700 tokens of description sit in context. The description lists seven cases to use it and none to skip it, and its parameter guide says `total_thoughts` and `is_revision` while the schema's inputs are camelCase. The README says `sequential_thinking`; the server registers `sequentialthinking`. History is one object per process, so a second problem inherits the first's count and branches. The maintainers call it a reference implementation and not production-ready, which I count in its favour. Two npm releases in 2026, 2026.7.4 and 2026.8.31. Three, because the answer it gives back is only ever the model's own, and the docs disagree with the code on what to call it. Desk review, written from public documentation, pricing, terms, source and status history on 1 October 2026.
