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. It mentions the 'confirm' parameter requirement, which hints at a safety or approval mechanism, but fails to describe other critical behaviors such as whether this operation is destructive, what permissions are needed, how errors are handled, or what the output looks like. This leaves significant gaps for a tool that likely creates persistent data.

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 appropriately sized and front-loaded, with the core purpose stated first ('Generate and save mind map') followed by the confirmation requirement. The 'Args' section is organized but could be more integrated into the main text. There's no wasted verbiage, though it could be slightly more polished for flow.

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 tool's complexity (4 parameters, no annotations, but with an output schema), the description is moderately complete. It covers the basic purpose and parameters but lacks behavioral details like error handling or side effects. The presence of an output schema means return values don't need explanation, but other contextual gaps remain, such as dependencies on sibling tools or system constraints.

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 description includes an 'Args' section that lists all four parameters with brief explanations, adding meaning beyond the input schema (which has 0% description coverage). However, the explanations are minimal (e.g., 'Notebook UUID' for notebook_id) and don't provide detailed semantics like format constraints, usage examples, or how 'source_ids' interacts with 'default: all'. This partially compensates for the schema gap but isn't comprehensive.

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 ('Generate and save mind map') and identifies the resource ('mind map'), which provides a specific verb+resource combination. However, it doesn't explicitly differentiate this tool from its sibling 'mind_map_list' or other content creation tools like 'infographic_create' or 'slide_deck_create', which prevents a perfect score.

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 implied usage guidance by mentioning 'Requires confirm=True after user approval,' which suggests a confirmation step is needed. However, it doesn't explicitly state when to use this tool versus alternatives like 'mind_map_list' or other creation tools, nor does it provide clear exclusions or prerequisites beyond the confirmation requirement.

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