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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. However, the description adds no behavioral context beyond the basic purpose—no mention of failure modes, authentication requirements, or output format. Since it adds nothing beyond what annotations and schema already convey, the value is minimal.

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, concise sentence that directly states the action and key qualifier (numeric ID). It contains zero redundant information and is optimally sized for a simple retrieval tool.

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 simplicity of the tool (2 parameters, clear purpose, and an output schema), the description is sufficient. It covers the essential retrieval semantics without needing to explain return values (covered by output schema) or complex behavior. The only slight gap is the lack of explicit usage guidance, but that is a minor omission for such a straightforward operation.

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 baseline is 3. The description does not add any additional meaning beyond the schema: it repeats that environment_id is numeric and does not elaborate on project (e.g., path vs ID). It provides no new insights into parameter usage, so it stays at the baseline.

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 clearly states the action (retrieve) and the resource (a single environment) with a specific identifier (numeric ID). It distinguishes itself from sibling tools like list_environments, which lists multiple, and get_deployment, which focuses on deployments. The purpose is precise and unambiguous.

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 implies usage when you have a numeric environment ID, but it does not explicitly state when to prefer this over list_environments or provide context like 'use this to fetch a specific environment after listing'. There is no when-not guidance or mention of alternatives, leaving the agent to infer the appropriate scenario.

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