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

Annotations already flag readOnlyHint=false, destructiveHint=false and openWorldHint=true; the description adds real value beyond that by stating no funds are committed or execution started, that HumanEndpoint returns commercial terms accept-or-decline, and that callback_url yields signed quote.offered/quote.declined webhooks instead of polling. No auth or rate-limit detail, so not 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?

Core purpose and the 'no commitment' constraint are front-loaded, and each subsequent sentence adds behavioral or routing value. The long suitable-tasks enumeration and webhook sentence make it wordier than strictly needed, but nothing is 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 a 9-parameter, open-world, mutation-adjacent tool with no output schema, the description covers the workflow and non-commitment well but leaves most parameter semantics unaddressed. Adequate for calling, thin on the input contract.

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 9 parameters, so the description carries the full burden, but it only illuminates callback_url (webhook behavior) and service_slug (custom-human-task fallback). objective, requester, constraints, deadline_at, deliverables, max_budget_usdc and max_expenses_usdc are left undocumented in both places.

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 ('Submit a request for human-reviewed terms for a real-world task') and scopes it against the alternative path by noting it 'does not commit funds or start execution', implicitly contrasting with human_create_job. Clear enough to route, though it never names a sibling directly.

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 concrete when-to-use guidance via the enumerated suitable tasks (calling a business for price/stock, phone-only info, fact verification, bounded research) and the custom-human-task fallback when no named service matches. It lacks an explicit 'use X instead' comparison to human_create_job, so it stops short of a 5.

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