Creates a persistent reasoning session so you can track what was checked, what was concluded, and what to do next.
DESCRIPTION
thinking is not a code reader. It is a stateful investigation layer for debugging, high-risk changes, and long sessions where it is easy to lose track of the work.
GOOD FIT
AVOID IT WHEN
| Name | Type | Required | Description |
|---|---|---|---|
| operation | "generate" | "cleanup" | Yes | Create a new reasoning session or clean up old ones. |
| task_description | string | No | Problem statement when creating a new session. |
| project_path | string | No | Absolute project path to anchor the investigation. |
PROJECT PATH
Add project_path when the reasoning session is tied to one repo. That gives downstream tool recommendations a concrete workspace anchor. If the problem is cross-system or mostly conceptual, you can omit it.

A thinking session usually starts around 300 to 900 tokens. That overhead is worth it when it prevents repeated dead-end reads and forgotten conclusions across a long debugging session.
