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

Annotations declare readOnlyHint=false and destructiveHint=false, so the mutation boundary is known, but the description adds nothing beyond the raw endpoint path. It does not say whether the change is idempotent, what permissions are required, or what happens to the existing shared/private state.

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 sentences with the purpose front-loaded before the endpoint reference; nothing is padded. It is appropriately sized but borders on under-specified for a mutation endpoint.

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 a nested body object, no output schema, and zero schema annotation coverage, the description is too thin. It omits side effects, response shape, and any confirmation of what the boolean toggles.

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 0% and the description never mentions parameters; only the raw path string hints at the {id} mapping. It does not clarify that the body's boolean sets visibility on/off, leaving the 2 required params to be inferred entirely from 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?

States a specific verb+resource combination ('Update LLM session public visibility'), which is distinguishable from the sibling put_strategy_llm_session_id_status and put_strategy_llm_session_id_reset. It does not explicitly name those siblings, but the resource noun is unambiguous.

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?

No when-to-use guidance and no mention of alternatives (e.g. the sibling status/reset endpoints or get_public_llm_session). The agent gets no condition that selects this tool over its near-identical siblings.

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