obsbot_preset_rename

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

Discloses truncation of names longer than 40 bytes and a verification step by re-reading. With no annotations, this is good behavioral context beyond the schema.

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?

Three concise sentences that front-load the purpose, then provide important details. No wasted words.

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?

Covers key behavioral aspects but lacks explanation of the camera parameter and return value. No output schema, so description should be more comprehensive.

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?

Explains slot and name truncation but does not describe the camera parameter, which is present in the schema. Schema coverage is 0%, so description should cover all parameters.

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?

Clearly states the action 'rename' and the resource 'preset slot 1|2|3', distinguishing it from sibling tools like delete or save. Includes a precondition that the slot must be occupied.

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?

Provides a precondition (slot must be occupied) but does not explicitly guide when to use rename versus update or save siblings, nor 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.
