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

With no annotations provided, the description carries full burden for behavioral disclosure. It states the tool performs write operations (add/update/delete) but doesn't mention permission requirements, rate limits, error conditions, or what happens to existing rules during updates/deletions. This is inadequate for a mutation tool with 11 parameters.

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 concise with two sentences that efficiently convey the core functionality. It's front-loaded with the main purpose and avoids unnecessary details. However, it could be slightly more structured by explicitly listing the three actions.

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 (11 parameters, mutation operations) and the presence of an output schema (which handles return values), the description is minimally adequate. However, with no annotations and significant behavioral gaps, it should provide more context about permissions, side effects, and error handling for a tool of this complexity.

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 100%, so the schema already documents all 11 parameters thoroughly. The description adds no additional parameter semantics beyond mentioning the three action types, which are already covered in the schema. Baseline 3 is appropriate when schema does the heavy lifting.

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 'manages conditional formatting rules on a Google Sheet' with specific actions (adding, updating, deleting), providing a verb+resource+scope. However, it doesn't explicitly differentiate from sibling tools like 'format_sheet_range' or 'protect_sheet_range', which might handle related formatting or protection tasks.

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 mentions 'supports adding, updating, and deleting' but provides no guidance on when to use this tool versus alternatives. There's no mention of prerequisites, when-not-to-use scenarios, or comparisons to sibling tools like 'format_sheet_range' for non-conditional formatting.

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