uac_reg_disable

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

Without annotations, the description carries the full burden. It explains that the tool disables and stops re-registration, but does not disclose side effects, permissions, or error conditions. Some behavioral context is provided, but it is not comprehensive.

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 concise sentence with no unnecessary words. It is front-loaded with the main action. However, it could benefit from additional structure, such as separating the action from the clarification.

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 is simple (one parameter), and the description provides the core purpose. However, it does not mention return values or status, and given the existence of an output schema, some information is missing. It is minimally complete for its complexity.

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 has no descriptions for the 'aor' parameter (coverage 0%). The description indicates that 'aor' is the address of record, adding meaning beyond the schema. However, it does not specify format or constraints, so it is partially helpful.

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 ('Disable'), the resource ('UAC registration'), and the key parameter ('by AOR'). It also explains the consequence ('stops re-registering'), distinguishing it from sibling tools like uac_reg_enable.

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 implies usage for stopping re-registration but does not explicitly state when to use this tool versus alternatives like uac_reg_enable or uac_reg_force_register. No exclusions or prerequisites are mentioned.

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