update_frozen_column_count

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

Annotations already indicate idempotency. The description adds that setting to 0 unfreezes all, which is useful. However, it does not disclose behavior on non-grid views or required permissions, leaving gaps.

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?

Two concise sentences effectively communicate the core functionality with no wasteful words. Could potentially be more succinct but already well-structured.

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 description covers the basic purpose but lacks constraints (e.g., valid range for frozenColumnCount, behavior if view is not a grid). No output schema exists, so description should be more precise. Adequate for a simple tool but not fully complete.

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 coverage is 100%, so baseline is 3. The description adds minimal extra meaning beyond schema (e.g., 'frozen-column divider position') but does not explain the debug parameter. The schema already describes each param adequately.

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 sets the frozen-column divider position for a grid view, specifying that the first N columns freeze. This distinguishes it from other view manipulation siblings like set_view_columns or apply_view_sorts.

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 freezing columns in a grid view but provides no explicit when-to-use or when-not-to-use guidance. No alternative tools are mentioned, though siblings exist for other view settings.

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