update_profile

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

With no annotations, the description must disclose behavioral traits. It only says 'Update', indicating mutation but fails to mention whether the update is a full replacement or partial, side effects, required permissions, idempotency, or how missing fields are handled. This is insufficient for a mutation tool.

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, which is concise. However, it sacrifices completeness for brevity, offering no additional context. While efficient, it does not earn its place due to lack of useful information beyond the tool's name.

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 absence of annotations, output schema, and any parameter explanations, the description is severely incomplete. It does not provide enough context for an AI agent to correctly invoke the tool, understand return values, or handle errors. The tool's complexity (4 params, nested object) demands far more detail.

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 4 parameters with 0% coverage in the description. The description does not explain any parameter's meaning, usage, or constraints. For example, 'profile' is a nested object with additionalProperties, but no guidance on its structure or required fields. This leaves the agent completely in the dark about parameter semantics.

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 'Update an existing device profile' clearly states the action (update) and the resource (device profile). It distinguishes from sibling tools like create_profile and delete_profile by specifying 'update', but does not differentiate from update_device or update_application beyond the resource name.

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 such as create_profile, update_device, or other update tools. The description lacks any context about prerequisites, typical use cases, or when not to use it.

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