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

With no annotations, the description carries the transparency burden. It discloses important behaviors: the tool returns a listing in 'pending' status with a source code ZIP and requires write-scope auth. This adds meaningful context, though it omits potential side effects or rate limits.

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 two sentences, front-loaded with the core purpose. Each sentence adds distinct value: the first defines the action, the second explains the output and auth requirement. No redundant information.

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?

For a tool with three parameters and no output schema, the description covers the essential context: purpose, output format (pending listing with ZIP), and auth scope. It lacks details on how the generated listing integrates with sibling tools, but given the simplicity, it is sufficiently complete.

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 already describes prompt and price, while category has only an enum with no description. The tool description does not add additional parameter context beyond reinforcing 'prompt', so it fails to compensate for the missing category explanation. Schema coverage is 67%, so the 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 a specific action: generate a full React template app from a text prompt. It also describes the output (a pending listing with source code ZIP), which distinguishes it from sibling tools focused on listing creation, deployment, or publishing.

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 the tool is used to generate template apps from prompts, but it does not explicitly mention when to use it versus alternatives or provide exclusions. The auth requirement is a precondition, not a usage guideline.

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