TDQS

A4.4/5.0

Behavior4/5

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

Annotations only declare readOnlyHint=false, so the description carries most of the burden and does well: it discloses the pull-mode fallback when no server is supplied and warns that member_secret is returned and shown once, which is critical since the value cannot be retrieved later. It omits idempotency/re-registration behavior and any auth or rate-limit context.

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

Conciseness5/5

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

Three short sentences, front-loaded with what the tool does, then requirements, then the mode switch, then the return caveat. Every sentence carries information an agent needs; nothing is redundant.

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

Completeness4/5

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

For a mutating registration call with an output schema already present, the description covers creation semantics, required fields, mode selection, and the one-time secret. It is nearly complete, with only re-registration/duplicate handling and confirmation of what else is returned left unstated.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3; the description adds meaning by clarifying the minimal required set and by explaining the behavioral consequence of omitting mcp_url rather than just its type. That extra signal lifts it slightly above the schema-only baseline.

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

Purpose5/5

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

States a specific verb (join/register) plus the resource and the choice space (seller, buyer, or both), which maps exactly to the roles parameter. It is clearly distinguishable from the similarly named sibling register_interest, which is a lighter-weight expression of interest rather than account creation.

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

Usage Guidelines4/5

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

Gives concrete operating guidance: only roles and name are required, and omitting mcp_url switches the agent into pull mode with a polling explanation. It does not, however, name alternatives (e.g. register_interest) or state when not to register, so it falls short of full routing guidance.

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