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

Annotations already declare readOnly=false, destructive=false, openWorld=false, so the safety profile is covered and not contradicted. The description adds essentially nothing beyond that — no permission requirements, no statement of whether the update is partial/merge, and no note that only 'name' is mutable here.

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?

Two short, front-loaded segments with no padding. The REST path adds little agent value and is slightly redundant, keeping it from a 5.

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?

For a mutation tool with no output schema and a nested body object, the description omits what the update affects, whether unspecified fields are preserved, and any permission context. It is too thin to call the tool correctly without opening the schema.

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?

Schema description coverage is 50% (only 'id' documented at the top level), so the description is expected to compensate but does not mention any parameter meaning. The useful detail about the optional 'name' lives in the schema, not the description.

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?

States a specific verb and resource ('Update LLM session folder'), and the resource is precise enough to separate it from the session-level sibling put_strategy_llm_session_id. It does not, however, explicitly name or contrast any sibling, so it stops short of a 5.

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?

There is no guidance on when to use this versus put_strategy_llm_session_id (update the session) or post_strategy_llm_session_folder (create a folder), and no prerequisites or conditions are stated. Only the REST path is provided, which is not agent-facing usage guidance.

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