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

No annotations are provided, and the description only states what the tool renders. It does not disclose side effects, permissions, or whether it is destructive. The agent has no behavioral context beyond the basic rendering action.

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 but fails to convey necessary information for a tool with 11 parameters. It is too short relative to the complexity.

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 high parameter count and absence of schema descriptions or annotations, the description is extremely incomplete. It does not explain how parameters interact, the expected output, or prerequisites. The existence of an output schema is not referenced.

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?

Schema description coverage is 0% (no parameter descriptions in schema), and the tool description does not mention any parameters. With 11 parameters including 'umap_only', 'tiles_only', 'sulcal_only', etc., the agent receives no help understanding their meaning or usage.

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 ('Launch Stage 6') and the specific outputs ('render sulcal graph meshes, cortical tile masks, and UMAP scatter plots'). It provides a specific verb and resource. However, it does not distinguish from sibling tools like start_cortical_tiles, which might overlap.

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 given on when to use this tool versus alternatives. The mention of 'Stage 6' implies a pipeline sequence, but no explicit context or prerequisites are provided.

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