get_group

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

No annotations are provided, so the description carries full burden. It mentions the Qiita Team restriction, which is useful behavioral context, but fails to disclose other critical traits: whether this is a read-only operation (implied by 'Get' but not explicit), authentication requirements, rate limits, error handling, or response format. For a tool with zero annotation coverage, this leaves significant gaps in behavioral understanding.

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 that front-loads the core purpose ('Get a specific group by URL name') and appends a restriction ('Qiita Team only'). There's no wasted verbiage, and it's appropriately sized for a simple lookup tool. It could be slightly more structured by separating the restriction into a second sentence for clarity, but overall it's concise.

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 tool's low complexity (single parameter, no output schema, no annotations), the description is minimally complete. It covers the basic action and a key restriction, but lacks details on authentication, response format, error cases, and sibling differentiation. For a read operation with no annotations, this is adequate but leaves room for improvement in guiding the agent effectively.

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 'url_name' fully documented in the schema as 'Group URL name'. The description adds no additional semantic context beyond what's in the schema—it doesn't explain what a 'URL name' is, provide examples, or clarify the Qiita Team context for the parameter. With high schema coverage, the baseline score of 3 is appropriate as the description doesn't compensate but doesn't detract either.

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 action ('Get') and resource ('a specific group'), and specifies the lookup method ('by URL name'). However, it doesn't distinguish this tool from its sibling 'list_groups' which presumably lists multiple groups, nor does it mention the Qiita Team restriction in relation to siblings. The purpose is clear but sibling differentiation is incomplete.

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 minimal guidance with 'Qiita Team only', indicating a platform restriction, but offers no explicit advice on when to use this tool versus alternatives like 'list_groups' or 'get_group_member'. There's no mention of prerequisites, error conditions, or typical use cases. Usage context is implied but not elaborated.

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