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

Annotations indicate idempotence and non-destructive nature. Description adds compliance context, key requirement, and two-step behavior. No contradictions.

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?

Three sentences, each adding value: purpose, procedure, compliance. No filler.

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?

Covers essential flow: two-step process, compliance gate, key requirement. No output schema but description implies return of text on first call.

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 description of 'acknowledgment' is generic. Description enriches it by explaining its role in the second call and how to obtain the exact phrase.

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?

Clearly states the action (record acknowledgment) and the resource (futures risk disclosure & Terms of Service). Links it to the prerequisite for join_bot. Could explicitly differentiate from siblings like approve_intent or complete_password_reset but context is strong.

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?

Explicitly states it's required before join_bot and outlines the two-call procedure. Does not list when not to use or alternatives, but the usage context is well-defined.

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