fetch_releases

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 optional pagination parameters but doesn't disclose behavioral traits like whether this is a read-only operation, what permissions are required, default pagination behavior, rate limits, or what the return format looks like. For a list operation with zero annotation coverage, this is inadequate.

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 brief and front-loaded with the core purpose ('List releases'), followed by parameter mentions. It avoids unnecessary words, though it could be more structured (e.g., separating purpose from parameter notes).

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, no output schema, and 0% schema description coverage for a 2-parameter tool, the description is incomplete. It lacks essential context like return format, pagination defaults, error conditions, or how it differs from sibling tools, making it insufficient for reliable agent use.

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 0%, so the schema provides no parameter documentation. The description adds minimal value by naming the parameters ('per_page', 'page') but doesn't explain their purpose, expected values, defaults, or constraints (e.g., numeric ranges, typical usage). This doesn't compensate for the coverage gap.

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 'List releases' states the basic action and resource, but is vague about scope and lacks differentiation from sibling tools like 'get_release' (singular) or 'fetch_activity_log' (different resource). It doesn't specify whether it lists all releases, recent releases, or releases with specific criteria.

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 guidance is provided on when to use this tool versus alternatives. With siblings like 'get_release' (singular fetch) and 'create_release'/'update_release'/'delete_release' (mutations), the description doesn't clarify that this is for listing multiple releases rather than fetching a specific one or performing mutations.

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