sdcloud_install_device_ca_certificate

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

Without annotations, the description must disclose behavioral traits, but it only states the purpose and parameter format. It does not indicate whether the operation is destructive, asynchronous, requires polling for status (despite a sibling tool sdcloud_get_install_ca_certificate_status existing), or any side effects. Additionally, the mention of 'multipart upload' is inconsistent with the schema expecting a base64 string, which could mislead an agent.

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 concise with two sentences and front-loads the purpose. However, the phrase 'multipart upload' is somewhat misleading given the schema, which slightly reduces efficiency. Still, it avoids unnecessary verbosity.

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 lack of output schema and annotations, the description should provide more context about return values, error conditions, or post-installation behavior. It does not mention that the operation may be asynchronous, or that the agent should check status via sdcloud_get_install_ca_certificate_status. The description covers only basic parameter hints, leaving significant gaps for an agent to use the tool correctly.

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 schema covers 75% of parameters with descriptions. The description adds value by explicitly stating that ca_certificate_content is base64-encoded and that ca_profile_id is associated. However, device_uuid and ca_certificate_file_name are not mentioned, and the schema already provides descriptions for the latter two. Overall, the description provides some additional semantic clarity but does not fully compensate for the missing schema descriptions.

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 (install a CA certificate) and the resource (device), and the mention of 'multipart upload' and parameters adds specificity. However, it does not explicitly distinguish from similar sibling tools like sdcloud_install_device_local_certificate or sdcloud_install_device_license, though the resource type 'CA certificate' provides some differentiation.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., listing certificates, installing local certificates). There are no prerequisites mentioned, such as the device or CA profile existing, nor any context on typical use cases or when to avoid this tool.

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