Debug Hello World

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

With no annotations provided, the description carries the full burden. It mentions returning a personalized message but doesn't disclose behavioral traits like whether it's read-only, has side effects, requires authentication, or handles errors. For a debug tool, this lack of detail is a significant gap.

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, efficient sentence in Portuguese, with no wasted words. However, it could be more front-loaded with key details, and the language might not be optimal for an AI agent if English is expected.

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?

Given no annotations, no output schema, and a simple parameter, the description is incomplete. It doesn't explain what the tool returns, how it integrates with the audio/MIDI context of sibling tools, or its debug purpose, leaving the agent with insufficient context.

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 description coverage is 100%, so the schema already documents the optional 'message' parameter. The description adds no additional meaning beyond what the schema provides, such as examples or constraints, meeting the baseline for high coverage.

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 'Ferramenta de debug que retorna mensagem personalizada' states it's a debug tool that returns a personalized message, which gives a basic purpose but is vague about what 'debug' means in this context. It doesn't distinguish from sibling tools, which are all audio/MIDI-related, making this tool's role unclear in relation to them.

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 guidance is provided on when to use this tool versus alternatives. Given the sibling tools are focused on audio/MIDI operations, it's unclear if this is a general debug utility or specific to that domain, leaving the agent with no usage context.

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