C2.8/5.0

Behavior2/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description only says 'Gets information', which adds no extra context beyond what annotations state. It does not describe output format, potential error cases, or any additional behavioral traits, so it fails to add value beyond the structured metadata.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single short sentence with no fluff, making it concise. However, it is so minimal that it lacks substance; the sentence 'Gets information about an environment' is almost a tautology of the title. It is appropriately short but underdelivers on useful information, so a 3 is fair.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite low complexity (1 param, no output schema), the description is too sparse. It does not hint at what 'information' is returned, nor does it mention any constraints like authentication scope. With no output schema, the agent is left guessing about the response structure. The description fails to round out the tool's context, so it scores 2.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema fully describes the single parameter environmentId, achieving 100% coverage. The description does not contribute any additional meaning, but the baseline for full coverage is 3. Since the tool is simple and the parameter is well-documented, a 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states the verb 'Gets' and resource 'environment', which is clear. However, it does not explicitly differentiate from sibling tools like getEnvironments (which likely lists environments) or hint that it retrieves a single environment by ID. The title and schema imply this, but the description itself lacks that distinction, so it scores 4.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

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. It does not mention that getEnvironments is for listing or that this is for a specific environment. There is no context about prerequisites or typical API workflows, so the agent gets no usage direction.

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