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

No annotations are provided, so the description carries full burden. It discloses key behavioral traits: 'Complete outside submissions are stored privately; public evidence remains content-free' and explicitly lists what it does NOT do (contacts no supplier, collects no payment, places no order, performs no engineering validation, grants no fabrication authority). This is valuable disambiguation in a domain with many workflow steps. Missing details on submission limits, time to qualification decision, or data retention policies. Good but not comprehensive.

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 sentences: first states the action, second describes privacy and lists non-actions. Front-loaded with the core purpose. No wasted words, but the second sentence is a lengthy list of negations that could be more concise. Structured effectively.

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?

Has an output schema, so return values need not be explained. However, for a complex submission tool with 7 required nested parameters, 0% schema description coverage, and no annotations, the description is incomplete. It covers purpose and some behavioral aspects (privacy, non-actions) but gives no guidance on how to properly fill out the extensive schema, what happens after submission, or how this fits into the broader workflow. Adequate minimum but clear gaps.

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 0% and there are 7 required parameters (with complex nested objects). The description adds no information about parameters beyond what's in the schema. The schema itself is somewhat self-documenting through property names, but the description doesn't compensate for the 0% coverage. The description mentions 'low-voltage outdoor sensor enclosure need' which hints at the need/scope parameters, but provides no detail on required fields like buyer, authority, commercial, or evidence. Baseline for 0 params is 4, but here we have 7 complex params and the description adds nothing.

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?

Specific verb+resource: 'Submit one real, unaffiliated low-voltage outdoor sensor enclosure need to A2A2P's fixed ten-submission qualification cohort.' This clearly states what the tool does and identifies a unique cohort mechanism not present in siblings. Lacks explicit sibling differentiation, but the specialized nature makes the purpose clear.

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?

No guidance on when to use this tool versus alternatives. The description doesn't explain prerequisites, conditions for use, or what to do after submission. Siblings like request_provider_estimate or build_supplier_request_package might overlap, but no routing information is provided. Only implication is that this is for low-voltage outdoor sensor enclosure needs.

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