Update a conversation

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

Annotations already declare readOnlyHint=false, idempotentHint=true and destructiveHint=false, so the safety profile is covered. The description adds real value by stating the required API key scope (conversations:write) and the HTTP verb/endpoint, which tells the agent this is an authenticated mutating call. It still omits what the mutation affects — e.g., whether a status transition to CLOSED or UNSUBSCRIBED has side effects — leaving a meaningful gap.

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?

Three short lines, front-loaded, with zero filler. It is efficient, though the terseness is partly the problem — the space saved is not used for any of the field or behavioral detail the agent needs.

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?

This is a mutation tool with a nested request body and no output schema, so the description must carry the load of explaining what changes and what is returned. It covers only the endpoint and auth scope, saying nothing about the updatable fields, the semantics of the status enum, or the response. Inadequate for a nested-body write operation despite the helpful annotations.

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 reported at 100%, but the actual descriptions are placeholders ("Path parameter `id`.", "JSON request body.") and the nested notes/status properties have no descriptions at all. The prose adds nothing about format, allowed status transitions, or whether notes replaces or appends. With coverage nominally high, the baseline of 3 applies, but the description misses an easy opportunity to compensate for the thin nested 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?

"Update a conversation" only restates the tool name and title; the only added information is the endpoint (PATCH /conversations/{id}). Nothing says which attributes can be changed (the schema's nested body reveals notes and status, but the description never surfaces them). Compared with a sibling like send_conversation_reply or delete_conversation_message, the description offers no distinguishing detail.

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 when-to-use or when-not-to-use guidance and no mention of alternatives among the many conversation siblings (get_conversation, send_conversation_reply, delete_conversation_message). The required scope hint implies a permission prerequisite but does not help select this tool over another.

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