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

No annotations are provided, so the description carries the full burden of behavioral disclosure. While 'Get debugging guidance' implies a read-only, non-destructive operation, it doesn't specify what form the guidance takes (text, links, steps), whether it requires specific permissions, or any rate limits. For a tool with zero annotation coverage, this leaves significant behavioral questions unanswered.

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, clear sentence with zero wasted words. It's appropriately sized for a tool with three parameters and no annotations, and it's front-loaded with the core purpose without unnecessary elaboration.

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 the lack of annotations and output schema, the description is incomplete for a debugging tool. It doesn't explain what kind of guidance to expect (e.g., troubleshooting steps, documentation links, code fixes), nor does it address behavioral aspects like permissions or limitations. For a tool that likely provides complex debugging advice, this leaves too much unspecified.

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 all three parameters with their types, enums, and descriptions. The description doesn't add any additional parameter semantics beyond what's in the schema, such as explaining how these parameters affect the debugging guidance or providing examples. The baseline of 3 is appropriate when the schema does the heavy lifting.

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's purpose as 'Get debugging guidance for React Native issues', which specifies both the action (get guidance) and the resource (React Native issues). However, it doesn't distinguish this debugging tool from the many analysis/optimization siblings like analyze_codebase_comprehensive or optimize_performance, which might also provide debugging-related insights.

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 provides no guidance on when to use this tool versus the many sibling tools available. With tools like analyze_codebase_performance, analyze_component, and optimize_performance that might overlap with debugging scenarios, there's no indication of when this specific debugging tool is preferred or what distinguishes it from alternatives.

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