rename_claude_session

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden of behavioral disclosure. It adds value by stating that the tool not only renames but 'verify[ies] the title in Claude's local session log', which is a behavioral step beyond the obvious action. It also implies that the session must be running, giving useful context. However, it does not mention side effects or permissions, but for a rename operation this is acceptable.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, front-loaded with the action 'Rename', and contains no wasted words. It communicates the core action and the verification step efficiently, earning a perfect score for conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers the core action and the verification step, giving enough context for an agent to understand what the tool does and when to use it. Given the tool's simplicity (3 params, no output schema), the description is reasonably complete. It does not mention return values or error handling, but these are not essential for a straightforward rename operation. A minor gap is lack of clarification on the managedSession parameter, but the schema default covers that.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has only 33% description coverage (only tmuxSession is described, as a deprecated alias). The description does not mention the title parameter, the managedSession default, or the relationship between parameters. Since schema coverage is low, the description should compensate, but it does not add any parameter-level semantics beyond what is in the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Rename the Claude conversation attached to a running managed session' – a specific verb (Rename), resource (Claude conversation), and scope (attached to a running managed session). It also mentions a verification step, distinguishing it from sibling tools like archive or list. This is more specific than a generic 'rename' and includes a unique follow-up action.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides clear context for when to use: when you need to rename the Claude conversation on a running managed session. It does not explicitly name alternative tools or state when not to use, but the action is well-defined. The prerequisite of a 'running managed session' is implied, which helps guide usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
