get_github_latest_release

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

Annotations are absent, so the description carries the burden. It discloses an external call to the approved api.github.com domain and a return of metadata, but it does not mention rate limits, auth, or failure modes. For a read-only metadata fetch, this is adequate but not rich.

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?

Three short sentences, main purpose first, no filler. The example and domain note each add practical value without bloating the description.

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?

With an output schema present, return structure is already specified. For a single-parameter external read tool, the example plus domain note cover most needs; the main omission is explicit when-to-use guidance, which is scored separately.

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 provides only a bare 'repository' string with 0% coverage. The example 'premake/premake-core' adds the owner/repo format implicitly, which is useful, but the description never explicitly explains the required format or any constraints.

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?

States a specific verb and resource ('Return the latest GitHub release metadata'), names the domain, and gives a concrete example. This is immediately distinguishable from generic web/file tools in the sibling list.

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 explicit when/when-not guidance or alternative tool is named. It only implies GitHub-specific use via the example and domain, but does not tell an agent when to prefer this over fetch_web_page or fetch_https_response.

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