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

The description includes extensive risk warnings: 'EXPERIMENTAL — TEST NETWORK ONLY — NOT A FINANCIAL PRODUCT OR SERVICE — NO REAL FUNDS — AS IS, NO WARRANTY, NO LIABILITY — USE AT YOUR OWN RISK.' These go beyond the annotations and clearly communicate the tool's non-production, experimental nature. No contradictions with annotations.

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 core instruction is concise and front-loaded. The long all-caps risk disclaimer is verbose but directly relevant given the experimental nature of the tool; it does not dilute the primary purpose.

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?

The description explains the purpose but omits what the tool returns (e.g., a boolean, a status object, or match details). Since there is no output schema, the absence of any return-value description leaves the tool's behavior incomplete for an agent.

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 schema provides only a regex pattern for intentId with no description. The description mentions 'posted purchase intent,' which gives some meaning to the parameter, but does not explain how to obtain the ID, its expected format beyond the pattern, or any related concepts.

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 primary action: checking once whether a posted purchase intent has joined a better-priced forming pool. It names the resource and action specifically, though it does not explicitly differentiate it from related sibling tools like get_match_status.

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?

The phrase 'Check once' provides some guidance on polling frequency, but there is no explicit instruction about when to use this tool versus alternatives such as caravan_get_match_status or caravan_commit. No usage context or conditions are given.

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