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

Annotations already declare destructiveHint=false, idempotentHint=true and openWorldHint=false, so the safety profile is covered. The description adds a genuinely useful behavioral fact beyond the annotations — the owner, not the caller, performs the actual submission — but says nothing about what happens to an existing delivery on re-delivery, whether delivery is final, or what a failed pairing means.

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?

Two tightly written sentences with the action and the ownership handoff front-loaded, and no filler or repetition of the schema.

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?

A mutation tool with no output schema, four parameters and only half documented — the description should say what a successful delivery returns and what happens on an invalid or expired pair_code. It covers the human-in-the-loop workflow well but leaves the caller-side contract thin.

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 only 50%: result and notes are documented in the schema, while task_id and pair_code have no description anywhere. The 'code, text, research' parenthetical adds a little meaning to result, but the two identifier parameters — including the opaque pair_code — are left entirely unexplained, so the description does not compensate for the coverage gap.

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 specific verb and resource: 'Hand the finished work product (code, text, research) for a task back to the owner's app.' The clause 'The owner reviews it and submits it on the provider's site' implicitly separates this from the sibling submit_work, though it never names the sibling explicitly.

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?

Usage is implied by 'finished work product' — call this when the deliverable is ready. But there is no explicit when-not guidance, no mention of prerequisites such as an active claimed task, and the alternative (submit_work) is only hinted at rather than named.

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