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

Annotations already indicate read-only, idempotent, and non-destructive behavior. The description adds meaningful context beyond annotations by disclosing the cost ('$0.25 USDC via x402') and output structure ('four-stage checklist'). This informs the agent of a required payment and expected output format, which are not captured in 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 description is extremely concise, consisting of two short sentences. It front-loads the core purpose, then adds pricing. Every word contributes value, with no redundancy or 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?

The description covers the tool's purpose, input, output stage count, and pricing. However, it does not specify the return format or structure of the checklist (e.g., markdown, JSON), and there is no output schema to fill this gap. Given the tool's simplicity, this is a notable but not critical omission.

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%, so the description must compensate. It mentions 'supplied project topic,' which clarifies that the 'topic' parameter is the subject for checklist generation. However, it does not elaborate on format, constraints, or examples. This is minimal but sufficient for a single free-text parameter.

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 function: 'Generate a structured four-stage checklist for a supplied project topic.' It specifies a verb (generate), a resource (checklist), and key attributes (structured, four-stage, project topic). This distinguishes it from sibling tools focused on audits, reviews, and briefs.

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 explicit guidance on when to use this tool versus alternatives. The description does not mention any prerequisites, exclusions, or alternative tools. While it implies use when a checklist is needed, it offers no comparison to sibling tools or context for when not to use it.

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