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

With no annotations available, the description carries the full behavioral burden. 'Return' implies a safe read operation and the description identifies the kinds of components included, but it says nothing about output format, whether the structure is static or generated dynamically, or any operational constraints.

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 tight sentences, front-loaded with what the tool returns and followed by when to use it. Every sentence earns its place and there is 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?

For a zero-parameter, annotation-free informational tool, the description is nearly complete: it explains the resource, the domain, and the calling context. It could say slightly more about what the returned structure contains beyond the category list, but no output schema exists to carry that burden.

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 tool takes zero parameters, so there are no parameter semantics to explain. Per the baseline for parameterless tools, a 4 is appropriate because there is nothing the description could meaningfully add about inputs.

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 states a specific verb and resource: it returns the standard internal structure of a Duck Framework blueprint. That clearly distinguishes it from generic project scaffolding, but it does not explicitly contrast itself with the closest sibling, get_project_structure.

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?

It gives a clear usage context: call this before generating a new blueprint or adding files to an existing one. It does not name an alternative tool or say when not to use it, so it falls short of the explicit when/when-not standard.

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