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. It states the tool fetches scores but doesn't describe what happens if the package doesn't exist, rate limits, authentication needs, or the format of returned data (e.g., numeric scores, timestamps). For a read operation with zero annotation coverage, this leaves significant gaps in understanding the tool's behavior.

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 Turkish that directly states the tool's function without unnecessary words. It's appropriately sized and front-loaded, with every part contributing to understanding the purpose.

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 complexity (a read operation with no output schema and no annotations), the description is incomplete. It doesn't explain what 'puanlar' (scores) or 'popülerlik skorunu' (popularity score) entail, how they're formatted, or potential error cases. For a tool that fetches data, more context on the return values and behavior is needed to be fully helpful.

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%, with the single parameter 'package_name' documented as 'Flutter paket adı' (Flutter package name) in the schema. The description doesn't add any parameter-specific details beyond what the schema provides, such as examples or constraints, so it meets the baseline for high schema 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 clearly states the tool's purpose: 'getirir' (gets/fetches) 'pub.dev puanlarını ve popülerlik skorunu' (pub.dev scores and popularity score) for a package. It specifies the action (fetching) and resource (package scores), though it doesn't explicitly differentiate from siblings like 'get_package_info' or 'get_package_documentation' beyond mentioning scores specifically.

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 sibling tools like 'get_package_info' (which might provide broader information) or 'search_packages' (for finding packages), leaving the agent to infer usage based on tool names alone.

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