update_dimension_group

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

With no annotations, the description carries full burden. It mentions 'collapse or expand' but does not disclose behavioral traits like effects on other groups, reversibility, or required permissions. The description is insufficient for a mutation tool.

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. However, it is too brief for a tool with 6 required parameters and no other documentation, sacrificing necessary detail for brevity.

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 6 required parameters and no output schema or annotations, the description is severely incomplete. It does not explain how indices work, valid values for dimension, or the effect of collapsed. The tool's complexity demands much more detail.

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%, meaning no parameter descriptions exist. The tool's description does not explain any of the 6 parameters (e.g., start_index, end_index, dimension, collapsed). The agent must rely on parameter names alone, which is inadequate.

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 tool collapses or expands a row/column group, using a specific verb and resource. However, it does not differentiate from sibling tools like add_dimension_group or delete_dimension_group, which also deal with dimension groups.

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 provided on when to use this tool versus alternatives. The implied usage from the name and siblings is present, but explicit context, such as when to collapse versus expand or prerequisites, is missing.

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