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

Goes well beyond the single destructiveHint:false annotation: accept returns an existing conversation, decline signals mismatch and may notify plus reschedule the other party, and the service has no persistent request dedup key so auto-retry is unsafe. That idempotency warning is exactly the kind of context annotations cannot convey.

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?

Front-loads the login requirement, then behavior, then safety guidance; nearly every clause carries operational weight. The trailing '用 get_my_dispatch 核对' partly repeats the opening reference to get_my_dispatch.inbound.

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 no output schema and 0% schema description coverage, the description covers auth, side effects, authorization requirements, and non-idempotency. The only real gap is the undeclared 'reason' parameter and any constraint on what declining communicates.

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 0%, so the description must carry parameter meaning. It effectively explains the accept/decline semantics and implies arrangementId comes from get_my_dispatch.inbound, but the 'reason' parameter (200-char max) is never mentioned and no format guidance for arrangementId is given.

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 clear verb+resource: respond to requests appearing in get_my_dispatch.inbound, with both accept and decline branches described. It does not name accept_dispatch_arrangement / decline_dispatch_arrangement, which cover similar ground in the sibling list, so the differentiation must be inferred.

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?

Gives strong operational guidance: requires login, must obtain user authorization before responding, and after an ambiguous result or timeout query current state rather than resending. It falls short of explicitly naming alternative sibling tools (accept_dispatch_arrangement/decline_dispatch_arrangement) for splitting the two actions.

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