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

No annotations are provided, so the description carries full burden for behavioral disclosure. While 'analyzes' and 'list project dependencies' imply a read-only operation, it doesn't explicitly state whether this requires specific permissions, what format the output takes, whether it handles errors gracefully, or any performance characteristics. For a tool with no annotation coverage, this is insufficient behavioral context.

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 extremely concise - a single sentence that efficiently communicates the core functionality. Every word earns its place, with no redundant information. It's appropriately sized for a simple single-parameter tool.

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 simple read operation with one well-documented parameter and no output schema, the description is minimally adequate. However, without annotations or output schema, it should ideally provide more behavioral context about what the analysis produces and any limitations. The mention of 'currently supports package.json' suggests evolving capabilities but doesn't fully address completeness.

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 input schema has 100% description coverage, with the single parameter 'filePath' well-documented in the schema. The description doesn't add any parameter-specific information beyond what's already in the schema (which mentions multiple file types including 'requirements.txt' while the description only mentions 'package.json'). Baseline 3 is appropriate when 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: analyzing dependency manifest files to list project dependencies. It specifies the verb 'analyzes' and resource 'dependency manifest files', and mentions current support for 'package.json'. However, it doesn't distinguish this tool from its siblings, which appear to be various generation and processing tools rather than dependency analysis tools.

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 alternatives. It doesn't mention any prerequisites, constraints, or scenarios where this tool would be preferred over other approaches. The sibling tools are all different in function (code generation, summarization, refactoring), so no explicit comparison is needed, but no usage context is provided.

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