github_repos_get_all_environments

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

No annotations provided, so the description must bear the full burden. It merely states 'List environments', implying a read-only operation but no disclosure of behavioral traits like rate limits, authentication needs, or side effects. The input schema covers parameters but not behavioral expectations.

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?

Extremely concise at two words, but this under-specification reduces clarity. While brevity is valued, here it sacrifices helpfulness. A more informative but still concise description would be better.

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?

The description is severely incomplete given the tool's complexity (4 parameters, no output schema, numerous siblings). It does not explain what the output represents, how pagination works, or when to prefer this over other list tools. This leaves an AI agent with insufficient 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 description coverage is 100%, so the schema alone documents parameters. The description adds no additional meaning beyond what is already in the schema. Baseline of 3 is appropriate.

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 environments' provides a clear verb and resource, but it lacks specificity about what 'environments' refers to in GitHub context (deployment environments for a repo). It is minimally clear but does not differentiate from other list tools.

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 on when to use this tool vs alternatives. With numerous sibling tools that also list resources (e.g., list branches, list deployments), the absence of usage context is a significant gap.

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