TDQS

B3.4/5.0
Behavior3/5

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

Annotations declare readOnlyHint=false and destructiveHint=false; the description usefully adds that no funds move and no website is required, filling in a real behavioral concern for a create-type tool. It does not disclose that repeated calls produce non-idempotent duplicate listings or what happens between prepare and publish.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short, front-loaded fragments with no filler; the key constraint ('No money moved') is placed early. The telegraphic style borders on under-specification rather than excess, so it is efficient but a little sparse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description is the only place to explain what an agent gets back and what to do next, and it omits the prepare→publish handoff entirely. The rich input schema and annotations cover most safety and parameter needs, but the lifecycle gap keeps this at minimum-viable.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% and the property descriptions already explain price=0 semantics, scope requirements, identity-only agent_id, and the contact_url fallback to the public inbox. The description's 'optional public marketplace inbox' echoes the contact_url fallback but adds no syntax or constraints beyond the schema, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: 'Generate an identity-signed service listing.' The title reinforces it as a 'prepare' step. However, it never distinguishes itself from the sibling publish_signed_offer, so the prepare-vs-publish boundary is left to inference.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

'No website needed' and 'No money moved' give implicit usage context (no hosted intake page, no payment taken), which helps an agent decide it's safe to call. But there is no explicit when-to-use/when-not, and no routing to prepare_signed_request, publish_signed_offer, or the intent-intake siblings.

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