Discover Dependencies

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

Annotations already confirm readOnlyHint=true and destructiveHint=false. The description adds context about scanning and grouping by ecosystem, but does not detail behavior like file scanning depth, timeouts, or error cases. With annotations covering safety, a mid score is appropriate.

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?

A single, well-structured sentence that conveys purpose, scope, and output format without redundancy. Every part is necessary and front-loaded.

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?

No output schema is provided, but the description hints at the output format ('grouped by ecosystem'). For a simple scan tool with no siblings, this is sufficient. Could mention edge cases or limitations but is mostly complete.

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 0 parameters, so schema coverage is 100%. The description adds meaning by explaining the tool's overall function without needing parameter details. A score of 4 reflects that no further parameter info is needed.

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 specifies scanning for specific manifest files (requirements.txt, package.json, etc.) and returning pinned dependencies grouped by ecosystem. The verb 'scan' and resource 'repository' are clear, and the list of file types provides concrete scope.

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 explicit when-to-use or alternatives are mentioned, but there are no sibling tools to distinguish from. The purpose is clear enough to imply usage for dependency discovery, though guidance on typical scenarios would improve it.

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