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

No annotations are provided, so the description carries the full disclosure burden. It specifies that both definitions and current values are retrieved, which adds useful behavioral context. However, it fails to explicitly confirm the read-only/non-destructive nature of the operation or mention pagination behavior implied by 'maxRecords'.

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, front-loaded sentence with no redundant words. However, it is arguably too concise given the lack of annotations and usage guidelines, leaving operational context underspecified despite the efficient structure.

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 has 3 optional parameters, an output schema (which handles return documentation), and simple scalar inputs, the description is minimally adequate. However, the absence of annotations combined with the lack of behavioral safety disclosure and usage guidelines leaves notable gaps for an agent making invocation decisions.

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%, establishing a baseline of 3. The description does not add specific parameter guidance (e.g., explaining that omitting 'environment' uses the default, or when to use 'managedOnly'), but the schema sufficiently documents all three parameters without additional textual support.

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 specific action (Get) and resource (environment variable definitions and current values) with scope (PowerPlatform environment). However, it does not explicitly differentiate from siblings like 'get-record' or 'query-records' that could theoretically retrieve similar data, though the specific resource naming helps implicit distinction.

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 provides no guidance on when to use this tool versus alternatives such as 'get-record' or 'query-records'. It does not mention prerequisites, nor does it explain when to filter using 'managedOnly' versus retrieving all variables.

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