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

Goes well beyond the annotations: discloses the payout amount (1 USDC, even for failed tests), that the order cost is NOT reimbursed, that the provider is never notified and cannot read the report, and that retrying is safe (consistent with idempotentHint=true). This is the kind of economic and privacy context an agent needs before committing.

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 action, then the prerequisites, then the payout/privacy terms; every sentence adds decision-relevant information. It is dense but not padded, though the ordering could be tightened into a clearer step sequence.

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 complex multi-step write with a nested evidence object, no output schema and thin schema coverage, the description covers the workflow and side effects well but leaves the unspecified required parameters and the response shape unaddressed. Adequate, but not complete for a tool of this complexity.

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 13%, so the description must carry the load, yet it explains only post_id, private_execution_evidence and execution_result. It never clarifies operator_url, payout_address, or that accept_bonus_terms and independent_operators are const-true gates, leaving required-but-unexplained parameters at both layers.

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 ('file a completed service order privately as a blind field test') and the workflow that produces the artifact, which clearly distinguishes it from siblings like speedbot_field_test_report and speedbot_dispute_field_test. An agent can identify the operation without opening the schema.

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 a concrete precondition chain (order an active service via the normal flow without contacting the provider; pay the accepted delivery or wait out the due time) and an explicit eligibility exclusion (any Work room with that provider makes it ineligible). It stops short of naming an alternative tool for the non-blind case, so it is clear context but not full when/when-not routing.

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