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

With no annotations, the description carries the full behavioral disclosure burden. It mentions 'bounded' (implying a polling limit) and 'recovery' (implying a state change), but fails to disclose side effects, failure modes, whether the operation is destructive, or what happens if authorization is insufficient. An agent is left guessing about the tool's actual impact.

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?

A tightly written single sentence that front-loads the action and scope. Every word earns its place, avoiding filler or redundant phrasing. It is appropriately concise for the action described, though it sacrifices explanatory depth for brevity.

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 the tool's complexity (5 parameters, nested objects, no output schema, no annotations), the description is grossly insufficient. It does not explain what 'CAPTCHA recovery' entails, how the polling budget works, what constitutes a valid 'task', or what the response will be. An agent cannot reliably construct a correct invocation from this description alone.

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 0% and the description provides no parameter-level explanation. The terms 'authorization', 'challengeDetected', 'task', 'context', and 'budget' appear in the schema, but the description gives no hints about their meanings, relationships, or expected values. The agent must infer everything from the schema alone, which the description should supplement.

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 names a specific verb ('Perform') and a clear resource ('CAPTCHA recovery'), with a scope constraint ('one bounded') and a precondition ('explicitly authorized Ruflo task'). It clearly communicates the core action, though 'Ruflo' is undefined jargon that may confuse an agent outside that domain.

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 implies it should be used only when a CAPTCHA is detected and authorization is explicit, as reflected in the schema constants. However, it gives no explicit when-not-to-use guidance, no mention of alternatives (though no siblings exist), and no context about when recovery would fail or should be retried.

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