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

Annotations declare write/open-world/non-idempotent, and the description adds genuinely non-structured behavior: this is an outbound transmission to an external company that must be gated behind human review and consent. It does not warn that a repeat call creates another submission (idempotentHint=false) or what happens on failure, which keeps it from a 5.

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, no filler, with the action front-loaded and the gating condition immediately after. Every clause earns its place.

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 30-parameter, nested-object terminal submission with no output schema, the description covers the crucial missing piece the schema cannot: the consent sequence that must precede the call. It omits any post-submission expectation (confirmation, errors, duplicate handling), so it is strong but not fully complete.

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 100% across all 30 parameters, so the schema already carries the field semantics; baseline is 3. The description only loosely reinforces what review_shown/legal_and_privacy_shown/person_said_yes mean by tying 'the review' to check_draft, and adds nothing for the other 27 fields or the nested object keys.

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 with a destination: 'Send the request to Marziale Technologies.' An agent can tell this is the terminal submission step, distinct from get_questions/get_offerings/check_draft, though no sibling is named for contrast.

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, hard precondition: 'Use only after the person saw the review, the legal line, the privacy line and link, and said yes.' This is a clear when-to-use gate that maps to the three required booleans. It stops short of naming alternatives (e.g., check_draft/fix_draft) explicitly, which is what a 5 would require.

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