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

With no annotations, the description must disclose behavioral traits. It only says 'in one transaction' but does not explain side effects (e.g., order consumption, AMM interaction), required permissions, failure modes, or atomicity. For a mutation tool, this minimal disclosure is insufficient.

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?

The description is a single sentence, concise but lacking structure. It conveys the core action efficiently but omits necessary details. It is not overly verbose, but the brevity hurts clarity given the tool's complexity.

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?

Given 5 parameters, no output schema, many sibling tools, and no annotations, the description is severely lacking. It does not explain what 'buy from order book + AMM' entails, how the parameters are used, or what distinguishes this tool from similar ones. The description is far from complete for correct agent invocation.

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?

The input schema has 5 parameters with 0% description coverage. The tool description adds no explanation of parameter meanings or usage. Without any parameter context, the agent cannot correctly invoke the tool.

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?

The description clearly states the tool's action: buying from private market order book and AMM in one transaction. It uses a specific verb and resource, and the phrase 'in one transaction' hints at a combined operation, distinguishing it from sibling tools like pm_buy_order or pm_buy_multiple_orders. However, it does not explicitly name alternatives or differentiate further.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., pm_buy_order, pm_buy_multiple_orders). There are no prerequisites, constraints, or exclusions mentioned. Given the large number of sibling buy-related tools, this is a significant omission.

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