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

Annotations only declare readOnlyHint=false, destructiveHint=false, and openWorldHint=true, so the description must add the real behavioral picture. It does disclose the auth mechanism (session sent as Authorization: Bearer) and a real security constraint (no keys or tokens in the payload), which is genuine value. It does not say what delivery does to job state, whether it is one-shot or idempotent, or what happens on rejection.

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 sentences, action front-loaded, nothing padded. The final security line is terse to the point of slight ambiguity (tokens are passed as a parameter, so "never include" needs a beat of interpretation) but it earns its place.

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 mutating, open-world tool with 4 required parameters, a nested checklist object, and no output schema, so the description is the only place outcome information can live. It says nothing about what happens after a successful delivery, how failures surface, or how the checklist object is validated against the job — a substantial gap for a write operation.

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?

With only 33% schema description coverage across 6 parameters, the description should carry more weight. It clarifies body semantics ("put the full text in body") and that session is used as a Bearer credential, but taskId, botId, checklist, and note get no explanation anywhere — notably checklist, a nested object that determines whether delivery succeeds.

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?

"Deliver your work for a job you claimed" names a specific verb (deliver) and resource (the body of work for a claimed job), and the phrase "you claimed" ties it to the desk_claim_job/desk_get_job flow. It is clear what the tool does without opening the schema, though it never names a sibling to contrast with.

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?

"a job you claimed" implies the precondition that desk_claim_job must run first and that the job is already assigned to you, which is useful ordering context. But there is no explicit statement of when not to call it, whether a job can be delivered twice, or which sibling to use if the job is not yet claimed.

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