B3.1/5.0

Behavior2/5

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

No annotations are provided, so the description must disclose behavioral traits. It only lists analysis types without mentioning side effects, permissions, output format, or whether it modifies files. This leaves the agent uncertain about the tool's runtime behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence that is to the point and contains no fluff. It is appropriately sized for the tool's purpose, though a more structured format could improve scannability.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (multiple analysis types), the description is insufficient. It does not explain what 'comprehensive' means in practice, how results are returned, or any operational constraints. With no output schema or annotations, the agent lacks critical context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema already describes both parameters with 100% coverage. The description adds context by listing the included analysis types, which aligns with the enum values. However, it does not add new semantic nuance beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it performs comprehensive React Native codebase analysis covering performance, security, refactoring, and upgrades. This distinguishes it from the many specific sibling tools like analyze_codebase_performance and analyze_component. However, it could be improved by using a stronger verb like 'perform' or 'run'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies this tool is for a broad analysis, but it does not explicitly state when to use it versus the more specific sibling tools. No guidance on prerequisites or scenarios is provided.

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