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

Annotations already mark this as non-read-only, open-world, and non-idempotent, but the description adds no behavioral context such as auth requirements, side effects of claim/create, idempotency handling, or failure modes. Listing REST routes is routing detail, not behavioral disclosure.

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 compact and front-loads the resource, then maps actions to endpoints. But the opening verb list is misleading and the dense endpoint notation makes scanning harder than it should be.

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 five-action dispatcher with 11 parameters, no output schema, and low schema description coverage, the description lacks critical details about response shapes, action prerequisites, and non-body parameters. It is not complete enough for an agent to call this tool reliably without opening external OpenAPI documentation.

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 only 9%, so the description must carry the burden, and it partially does by naming claim and create body fields. However, it omits agent_key usage for list/claim/create, idempotency_key, token semantics, and several other parameters, leaving most of the 11-parameter surface unexplained.

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 concrete resource (client-branded redeliveries) and lists both reads and mutations, but the opening sentence says 'authorize' and 'verify' even though the action enum contains claim, create, list, read, and download. That mismatch makes it unclear which verb maps to which action, though the endpoint list partially rescues it.

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 lists endpoints and required body fields but never says when to choose one action over another, nor when to use this tool versus a sibling. An agent must infer action choice entirely from endpoint semantics.

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