Retrieve secret file

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false. Description adds the specific GET endpoint, confirming it's a read operation. No additional behavioral details beyond annotations, but no contradictions.

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?

Two sentences: a title-like first sentence and a descriptive second sentence with the API call. Both are relevant and concise, no wasted words. Could be slightly more efficient by merging, but still good.

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?

No output schema, but for a simple retrieve operation, the description and annotations (readOnlyHint, openWorldHint) suffice. The agent can infer the return type. It does not explain return format, but given low complexity, it is adequate.

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 coverage is 100% with parameter descriptions. The description reinforces the parameter roles via the API path template but does not add new semantic details. It is clear and aligns with schema, but no extra value beyond what schema already provides.

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?

Description specifies a particular secret file in a particular environment group, clearly distinguishing it from similar tools like render_retrieve_secret_file (no env group) and render_retrieve_env_group_env_var (env var vs secret file). The verb 'retrieve' plus resource is specific 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?

States exactly what the tool retrieves and includes the API call, which helps the agent understand context. However, it does not explicitly mention when to use this tool over alternatives or when not to use it, lacking exclusionary guidance.

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