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

Annotations already declare readOnlyHint=false, destructiveHint=true, idempotentHint=false, so the safety profile is covered. The description adds nothing beyond that, and worse, it claims a two-way toggle between 'open' and 'resolved' while the schema requires an explicit status with a third 'pending' value — the stated behavior does not match the contract.

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?

Very short and front-loaded, but the first sentence 'Toggle Status.' merely repeats the tool title and consumes space without adding information; the remaining sentence is the only substantive content.

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 two-parameter mutating tool with no output schema, the description should at minimum state that status is caller-specified and list the accepted values. Instead it omits 'pending' and mischaracterizes the operation as a toggle, leaving the agent with an incorrect mental model.

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 coverage is 100%, so the baseline would be 3, but the description actively degrades understanding: it implies only two possible statuses when the enum lists three ('open', 'resolved', 'pending'), and it frames the operation as a toggle rather than a caller-specified status assignment.

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?

It names a verb (toggle) and resource (conversation status), which is more than a bare restatement, but 'toggles' misdescribes what the required 'status' parameter actually does (it sets an explicit status). It also fails to distinguish itself from close siblings like update_conversation or toggle_priority_of_a_conversation.

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 indication of when to use this versus update_conversation or the other toggle_* tools, no prerequisites, no note on required permissions. The agent gets no routing guidance at all.

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