download_client_keystore

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

No annotations are provided, so the description carries the full burden. It only mentions 'download' but does not disclose behavioral traits such as whether the operation is read-only, requires specific permissions, or what the response format (e.g., binary file) is. This is insufficient for an agent to understand side effects.

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 sentence of 16 words, concise and front-loaded with the primary action. However, it could be slightly more informative without becoming verbose, given the tool's complexity.

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?

The tool has 4 required parameters including a nested object, and no output schema. The description lacks critical information about the return value (binary download, URL, etc.) and error conditions. For a download operation, the agent needs to know how to handle the response, which is not addressed.

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 has 100% coverage with descriptions for each parameter. The description adds minimal value by noting that 'config' is a 'keystore configuration', but it does not explain how to use the config parameter or the interplay with other parameters. Baseline 3 is appropriate given high schema coverage.

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 action (download) and resource (keystore file for a client certificate). However, it does not explicitly differentiate from similar download tools like 'generate_and_download_client_keypair', which might confuse an agent about whether to use this tool for existing vs generated keystores.

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 vs alternatives, no prerequisites, and no exclusions. It only states the action without context about the appropriate scenario.

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