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

Annotations already declare readOnlyHint=false, idempotentHint=true, and destructiveHint=false, so the safety profile is largely covered. The description usefully adds that responding confers no execution, messaging, or payment authority, which is real context beyond the annotations, but it says nothing about visibility semantics, the private_note/share_approved gating, or what happens on re-submission.

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 tight sentences with the action front-loaded and the authority caveat second; every clause earns its place. It is arguably too terse for a 10-parameter mutation tool, but there is no filler or redundancy.

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 non-read-only tool with 10 parameters at 0% schema coverage, nested objects, and no output schema, two sentences are far short of what an agent needs. Key behaviors such as visibility effects, private_note handling, share_approved gating, and idempotent replay semantics are absent.

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% across 10 parameters (8 required, nested sources/conditions objects), so the description must carry the semantic burden and does not. 'Advice or evidence' loosely hints at summary and sources, but nothing is said about visibility, private_note, share_approved, idempotency_key, language, or the sources.kind enum, leaving most parameters undocumented.

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 (respond) and resource (an accessible, open request) plus the payload type (advice or evidence), which separates it from create_request and list_requests. It never explicitly names a sibling or explains how it differs from submit_outcome or report_reuse, so it is clear but not fully differentiated.

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 phrase 'accessible, open request' implies a precondition that the target request must exist and be open, which is useful routing context. However, there is no explicit when-to-use versus create_request, submit_outcome, or report_reuse, and no statement of what to do when the request is closed or inaccessible.

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