TDQS

C2.7/5.0
Behavior2/5

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

The description adds no behavioral context beyond the annotations. It merely says 'Create', which is consistent with readOnlyHint=false and destructiveHint=true, but it does not disclose that this action is high-risk, may lock funds, or requires explicit user confirmation. The confirm parameter hints at this, but the description itself provides no such transparency.

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?

The single sentence is clear, front-loaded, and free of filler. However, for a tool with this many parameters and no other guidance, the brevity borders on under-specification rather than efficient completeness.

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

Completeness1/5

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

The definition is severely incomplete for the complexity involved: 15 required parameters, nested objects, no output schema, and almost no parameter documentation. The one-sentence description does not enable an agent to construct a valid request or understand what will happen when posting an ad.

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

Parameters1/5

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

With 15 required parameters and only 7% schema description coverage, the description needed to explain at least the core fields. It explains none of side, priceType, premium, quantity, paymentPeriod, itemType, paymentIds, or tradingPreferenceSet, so an agent cannot infer their meaning from the tool definition.

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?

The description 'Create a new P2P advertisement' uses a specific verb and resource, clearly identifying the operation. It distinguishes postAd from sibling ad tools like getAds, getMyAds, updateAd, and removeAd.

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

Usage Guidelines2/5

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

No guidance is provided on when to use this tool versus alternatives such as updateAd or removeAd. There is no mention of prerequisites, exclusions, or conditions that should be checked before posting an ad.

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