update_device_config

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

With no annotations provided, the description carries the full burden of behavioral disclosure. While 'Update configuration' implies a mutation operation, it doesn't disclose important behavioral traits like: whether this requires specific permissions, if changes are reversible/destructive, what happens to existing configuration not mentioned, potential side effects, or what the response looks like. For a configuration mutation tool with zero annotation coverage, this is a significant gap.

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, efficient sentence with zero wasted words. It's appropriately sized for a tool with good schema documentation and gets straight to the point without unnecessary elaboration. Every word earns its place in conveying the core purpose.

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?

For a configuration mutation tool with 4 parameters (including nested objects), no annotations, and no output schema, the description is insufficient. It should address: what 'configuration' encompasses, whether changes are immediate or require restart, error handling, permission requirements, and what the tool returns. The current description leaves too many behavioral questions unanswered for safe and effective use.

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 description coverage is 100%, so all parameters are documented in the schema itself. The description doesn't add any meaningful parameter semantics beyond what's already in the schema - it doesn't explain the structure of config_changes, provide examples of valid configuration values, or clarify relationships between parameters. This meets the baseline expectation when schema documentation is complete.

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 ('Update') and resource ('configuration of an existing device'), making the purpose immediately understandable. However, it doesn't differentiate this tool from other update-related tools in the sibling list like 'update_server_credentials' or 'update_mcp_admin_groups', which would require more specific language about what makes device configuration updates unique.

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. With many sibling tools available (like 'control_vm', 'deploy_vm', 'manage_proxmox_vm'), there's no indication whether this is for physical devices, virtual machines, or specific infrastructure components. No prerequisites, exclusions, or alternative tools are mentioned.

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