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

No annotations provided, so description carries full burden. It reveals token limiting and retrieval nature (no mutation implied). However, it does not explicitly state that the tool is read-only or describe side effects. Lacks details on output format or pagination behavior. Still, the description is largely transparent about core 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?

Two concise sentences, no superfluous information. The key purpose and prerequisite are front-loaded. Every sentence adds value.

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 no annotations or output schema, the description covers the main behavioral aspects (retrieval, token limiting, prerequisite). However, it lacks details on pagination behavior and return format, which are relevant for a retrieval tool. Overall, it is sufficient but not exhaustively 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?

Schema description coverage is 100%, so schema already documents all parameters. The description adds context by explaining when to use certain parameters (e.g., 'You must call find_awesome_section first... UNLESS the user explicitly provides a githubRepo or listId'). This provides usage guidance but does not add semantic depth beyond the schema for individual parameters.

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?

Description clearly states 'Retrieves items from a specific awesome list or section with token limiting.' The verb 'Retrieves' and resource 'awesome list or section' are specific. It differentiates from sibling tool 'find_awesome_section' by noting the prerequisite call, establishing its distinct role.

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?

Explicitly states when to use: 'You must call find_awesome_section first... UNLESS the user explicitly provides a githubRepo or listId.' This gives clear context and exclusion, directly guiding the agent on prerequisites and alternatives.

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