foaas_understand

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

No annotations are provided, so the description carries the burden. It states that the tool 'expresses genuine confusion' but does not disclose whether it is a read-only operation, returns text, or any side effects. For a simple message-generating tool, this is minimally adequate but could be improved by explicitly stating it only returns a message and is non-destructive.

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?

Two sentences, front-loaded with usage condition, no wasted words. Every sentence adds value: first tells when to use, second clarifies what it expresses.

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 covers when to use and what it expresses, but lacks information about return format, behavior (e.g., if it's a read-only operation), or any output schema. Given the tool's simplicity and sibling context, it's adequate but not thorough.

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?

Schema coverage is 100%, so the schema already documents both parameters. The description adds context by explaining the purpose (e.g., 'to' directs confusion at someone), but it does not add new details beyond what the schema provides. Baseline is 3.

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 expresses confusion when requirements are unclear or explanations are confusing. It specifies the resource (the target of confusion) and action (express confusion), but the name 'foaas_understand' could be misinterpreted as understanding rather than confusion, slightly reducing clarity.

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 description explicitly lists when to use this tool: when requirements, code, documentation, or explanations are confusing. It provides clear context for usage, differentiating it from sibling tools that express other emotions (e.g., foaas_asshole for anger), though it lacks explicit when-not-to-use guidance.

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