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

No annotations are provided, so the description carries the full behavioral burden, yet it never states that this is a read-only operation, whether results are paginated, or how large the response can be. The only behavioral hint is that each environment carries a live release and URL, which is minimal disclosure.

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?

It is a single front-loaded fragment with no wasted words, but it is under-specified rather than genuinely concise. The trailing 'with live release and URL' phrase is ambiguous about whether it describes return fields or filter criteria.

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?

For a low-complexity, single-parameter tool with no output schema this is roughly the minimum viable amount, since the return content is sketched (live release, URL). However, it omits read-only framing and any routing against the many sibling env.* tools.

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?

There is a single parameter with 100% schema description coverage, so the schema already documents 'project'. The description adds no format, naming, or validation detail beyond what the schema provides, making the baseline 3 correct.

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 fragment names the resource (environments) and its scope (a project) and hints at return content (live release and URL), but it is a noun phrase rather than a specific verb+resource statement. It does not clearly distinguish itself from sibling read tools like env.status, so an agent must infer that this lists rather than reports status.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives such as env.status or env.exec. The agent is left to infer from the name alone that this is the enumeration variant.

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