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. 'List releases' gives no information about permissions required, rate limits, pagination, error handling, or what the output looks like (e.g., format, fields). For a tool with no annotation coverage, this is a significant gap in transparency.

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?

While concise with only two words, the description is under-specified rather than efficiently structured. It lacks front-loaded critical information (e.g., what system or context) and doesn't earn its place by adding value beyond the tool name. Conciseness should not come at the cost of clarity.

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 list operation with 2 required parameters), no annotations, and no output schema, the description is incomplete. It doesn't explain what 'releases' are, how results are returned, or any behavioral aspects. For a tool in a server with many sibling tools, more context is needed to guide proper 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?

The description adds no meaning beyond what the input schema provides. However, schema description coverage is 100%, with clear descriptions for both required parameters ('provider' and 'repo'), so the baseline score of 3 is appropriate. The description doesn't compensate but doesn't need to since the schema is fully documented.

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' is a tautology that merely restates the tool name 'release_list' without adding any meaningful clarification. It doesn't specify what kind of releases (software releases, deployment releases, etc.) or from what system, nor does it distinguish this tool from sibling tools like 'release_create' or other list tools in the server.

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 prerequisites (e.g., authentication), context for use (e.g., after cloning a repo), or differentiate it from similar tools like 'gitea_list_repos' or 'github_list_repos' that might handle releases differently. There's no explicit or implied usage advice.

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