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

With no annotations, the description carries the full burden. It usefully discloses the cost profile (no-cost) and the non-committal nature of a quote, but says nothing about auth requirements, rate limits, what the quote contains, or what task_type accepts. Partial behavioral coverage only.

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, purpose front-loaded in the first. The second sentence's long category list is somewhat padded with 'and other lawful current-data tasks,' but it is far from bloated.

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?

No output schema, no annotations, and a nested parameter at 0% schema coverage. The description omits quote structure, constraints shape, valid task_type values, and follow-up steps, so an agent lacks enough to invoke this confidently beyond the required field.

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% with 2 parameters, one a nested 'constraints' object. The description lists task categories (research, procurement, bids, vendors...) that loosely hint at task_type values but never maps them to the parameter, and leaves the nested constraints object entirely unexplained.

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: 'get a no-cost quote for deeper PaidHandshake worker fulfillment.' The cost-free and pre-spend framing distinguishes it functionally from get_unlock_quote and submit_paid_machine_job, though no sibling is named explicitly.

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?

'before a machine account spends anything' implies the timing context (pre-commitment estimation), which is genuinely useful. However, it names no alternatives and gives no explicit when-not guidance versus get_unlock_quote or submit_paid_machine_job, leaving routing to inference.

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