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

It discloses the key side effect not captured by annotations: repeated calls generate a fresh link and retire the previous one, highlighting non-idempotency. It also states the validation precondition that all screenshots must be uploaded and be real PNG/JPEG.

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 compact sentences front-load the core behavior and then cover repeated-call semantics. No filler or duplication of schema content.

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 single-parameter tool with no output schema, the description supplies the input origin, validation behavior, and result link. It lacks explicit failure behavior if validation doesn't pass, but the main invocation path is well covered.

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 documents project_handle at 100% coverage, so the description does not need to repeat parameter details. It adds no extra parameter meaning beyond calling it 'a project.'

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 identifies a specific action (finish) applied to a project resource and details the behavior: validating all uploads and returning an editor link. This clearly separates finish_project from create_project, get_workflow, and list_devices.

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 after a project's screenshots have been uploaded, and the validation step gives clear contextual hints. However, it does not explicitly state when not to use it or name alternatives, so it stops short of full routing guidance.

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