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

With no annotations provided, the description carries the full burden of behavioral disclosure but offers none. It doesn't indicate whether this is a read-only operation, what permissions might be required, whether results are paginated (despite the $top parameter), what format the output takes, or any rate limits. The description provides zero behavioral context beyond the bare verb 'list'.

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 the description is extremely brief (two words), this represents under-specification rather than effective conciseness. The description fails to provide any meaningful information that would help an AI agent understand when and how to use this tool. Every sentence should earn its place, but this description doesn't provide even a single complete sentence of useful guidance.

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 that this is a listing tool with 4 parameters, no annotations, and no output schema, the description is completely inadequate. It doesn't explain what 'releases' means in this context, how results are returned, what authentication might be required, or how this differs from the 'get_release' sibling tool. The description fails to provide the minimal context needed for effective tool selection and invocation.

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 input schema has 100% description coverage, so all parameters are documented in the schema itself. The description adds no additional parameter information beyond what's already in the schema descriptions. According to the scoring rules, when schema_description_coverage is high (>80%), the baseline is 3 even with no param info in the description, which applies here.

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 without adding meaningful context. It specifies the verb 'list' and resource 'releases', but doesn't distinguish this from sibling tools like 'get_release' or provide any scope information about what kind of releases are being listed (e.g., project releases, organizational releases, etc.).

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 absolutely no guidance on when to use this tool versus alternatives. It doesn't mention sibling tools like 'get_release' (which appears to fetch a single release) or explain when filtering via parameters is appropriate versus using other listing tools. There's no context about prerequisites, limitations, or typical use cases.

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