v0.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden. It discloses that the tool fetches comments and returns a formatted discussion thread with nested replies, which implies a read-only operation. However, it does not mention authentication requirements, rate limits, or error handling, which could be relevant for a read operation.
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 concise and well-structured, with the purpose in the first sentence followed by Args and Returns sections. No unnecessary words are present, making it easy to scan.
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 single-parameter tool with an output schema present, the description provides sufficient context by stating the return format. It does not discuss error conditions or edge cases, but given the simplicity, it is reasonably 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 description restates the parameter as 'Integer ID' with no additional semantics. Since schema coverage is 0%, the description should provide context like the format of the ID or how to find it, but it does not, leaving the parameter meaning only as the schema states.
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 verb 'Fetch' and the resource 'threaded discussion comments for a DEV.to article', which is specific and distinct from the singular 'devto_get_comment' sibling. It avoids tautology and gives the agent a clear idea of the operation.
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 the sibling 'devto_get_comment' or other article-related tools. It does not mention exclusions or alternatives, leaving the agent to infer context.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
