validate_astah_environment

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

With no annotations, the description carries the burden. It explicitly states 'sem alterar projetos' (without altering projects), which discloses non-destructive behavior. However, it does not describe return values, failure modes, or any other behavioral details such as network calls or side effects.

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 a single, concise sentence that front-loads the purpose and includes a key safety note ('sem alterar projetos'). Every word earns its place with no redundancy.

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 validation tool, the description adequately outlines what is validated and that it is non-destructive. However, without an output schema, it does not clarify what the tool returns (e.g., success/failure, diagnostic details), which is a notable gap.

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 has zero parameters, so the schema provides all necessary information. The description adds no parameter details, but none are needed; baseline of 4 is appropriate.

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 validates the Astah environment installation, API, exporter, and compilation. The verb 'Valida' (validates) combined with the specific resource distinguishes this from sibling tools that create models or verify layout.

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 usage for checking the environment before doing other operations, but it provides no explicit guidance on when to use this tool versus alternatives, nor does it mention prerequisites or expected workflows.

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