github_repos_get_environment

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

No annotations are provided, so the description carries full burden. It states 'Get' which implies a read operation, but does not explicitly confirm safety, required permissions, or behavior on missing environments. This is inadequate for a tool with no annotation support.

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 sentence, which is concise and well-structured. However, it is under-informative, earning a slight deduction from a perfect score.

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 simplicity (get by 3 params, no output schema), the description is incomplete. It does not explain what an environment is, what the return value contains, or how it differs from listing environments. The output schema is absent, so the description should provide more context.

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 coverage is 100% with basic parameter descriptions (just the parameter names). The tool description does not add any additional meaning beyond the schema. Baseline of 3 is appropriate since the schema already covers the parameters, but the descriptions are minimal.

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 'Get an environment' uses a specific verb and identifies the resource, but it is minimal and does not specify that it refers to deployment environments in GitHub, nor does it distinguish from sibling tools like 'get_all_environments' or 'create_or_update_environment'.

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. Sibling tools include list and create/update environment functions, but the description does not clarify that this retrieves a single environment by name, nor does it mention prerequisites or exclusions.

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