get-setting-value

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

Without annotations, the description adds value by clarifying that rolloutRules and percentageRules are returned in evaluation order and explaining what the value attribute represents (fallback value). However, it does not explicitly state that the operation is read-only or mention any authorization or rate-limiting details.

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 relatively concise with four sentences. It front-loads the purpose and then details the response attributes. Minor redundancy in discussing rolloutRules and percentageRules, but overall efficient.

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's simplicity (2 parameters, no output schema), the description explains the response structure and key attributes adequately. It includes a link for further reading. However, it does not cover error conditions or prerequisites (e.g., what if environmentId is invalid).

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?

The input schema already provides descriptions for both parameters (environmentId and settingId) with 100% coverage. The description only minimally adds by mentioning environmentId in the first sentence, but does not elaborate on settingId or add meaning beyond the schema.

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 that the endpoint returns the value of a feature flag or setting in a specified environment, identified by environmentId. It explains the key response attributes (value, rolloutRules, percentageRules) and their significance, distinguishing it from siblings like get-setting (which likely returns the setting definition) and get-setting-values (which might return values across environments).

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-setting-values or get-setting-value-v2. There is no explicit mention of when to use or not use this tool, nor any comparison with sibling tools.

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