Close Conversation

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

Annotations already indicate destructiveHint=true and idempotentHint=true. The description adds minimal behavioral context beyond what annotations provide – it confirms the destructive nature but doesn't disclose side effects (e.g., whether messages become read-only, if the conversation can be reopened, or if there are permission requirements). This is insufficient for a destructive operation.

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 concise sentence that front-loads the purpose. However, it may be overly concise given the lack of guidance and behavioral context – a few more sentences could improve completeness without harming 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?

Given the presence of many sibling conversation manipulation tools and minimal description, the tool lacks sufficient context for correct selection. No explanation of prerequisites, effects, or relationship to other tools. The output schema is absent, but that is not the main issue. The description is incomplete for an agent to use confidently.

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% with a clear description of the 'id' parameter. The description does not add any additional meaning beyond the schema. Baseline 3 is appropriate.

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 the action ('close') and the resource ('active conversation') and the outcome ('marking it as completed'). It distinguishes from sibling tools like 'release_conversation' or 'takeover_conversation' by using the verb 'close' and specifying 'completed'. However, it could be more explicit about the precise operation.

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 no guidance on when to use this tool versus alternatives. With siblings like 'release_conversation' and 'takeover_conversation', the agent lacks context to decide which is appropriate. No explicit when-to-use or when-not-to-use information.

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