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

Goes well beyond the annotations: it clarifies that retries recover the same request (reinforcing idempotency with operational detail), redefines the 'sent' outcome as provider acceptance rather than inbox delivery, and names the delivery_unknown state with required follow-up. These are exactly the semantic distinctions an agent cannot infer from idempotentHint/openWorldHint alone.

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?

Five short sentences, each carrying distinct operational information (precondition, parameter provenance, retry semantics, success meaning, error handling). The precondition is front-loaded and there is no filler.

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 an irreversible, open-world send operation with no output schema, the description covers the precondition, the success semantics, the ambiguous failure state, and retry behavior. An agent has everything needed to invoke it correctly and interpret the outcome.

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%, so the description must compensate: it tells the agent where operation_id and version come from (review_request / the reviewed version), which is the key provenance constraint. It does not explain the 64-character version format or UUID constraint, but the schema's type/format/pattern fields already constrain those values.

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 concrete action on a concrete resource (send the confirmed Document Request version), and routes the agent through the review step by naming reviewUrl and review_request. It does not explicitly contrast itself with get_request or prepare_request, so sibling differentiation is implied rather than spelled out.

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 an explicit precondition ('Send only after the Professional confirms the exact version on reviewUrl') and an explicit prohibition for the failure path ('delivery_unknown requires inspection in DokuTrak; do not start over or resend'). It also closes the alternative route by stating no immediate reminder is available.

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