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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false, so the agent knows this tears down state and is not repeatable. The description adds genuinely useful operational context about polling dialogue_result for late reviews, but it does not confirm the session is destroyed or whether results survive the call.

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?

A single compact sentence with the action front-loaded before the parenthetical caveat. Efficient, though the cryptic 'summary.pending > 0' reference packs a lot of unstated context into a short clause.

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?

With no output schema, the description carries the burden of describing what comes back, and 'return the result' is notably vague about the response shape. The dialogue_result caveat partially compensates, and annotations cover the destructive profile, making this adequate but incomplete.

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 session_id, so the sole required parameter is explained by neither structured data nor prose. The name is fairly self-evident in a dialogue context, but the description does not compensate for the coverage gap.

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 ('End the conversation') that clearly distinguishes it from dialogue_start, dialogue_turn, and dialogue_state. It also implies a return value, though the pairing with dialogue_result is only partially explained, so sibling differentiation is present but not fully sharp.

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 parenthetical about late reviews arriving via dialogue_result while summary.pending > 0 hints at when to follow up with a different tool, which is real usage guidance. However, it never states when to call this versus letting a dialogue lapse, nor any precondition for ending, so guidance is implied rather than explicit.

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