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

No annotations are provided, so the description carries full burden. It states 'renames', implying a mutation, but doesn't disclose behavioral traits like required permissions, whether changes are reversible, rate limits, or what the output contains. This leaves significant gaps for an agent to understand the tool's behavior safely.

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, efficient sentence with zero waste. It's front-loaded with the core action and target, making it easy to parse quickly without unnecessary details.

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 has an output schema (implied by context signals), the description doesn't need to explain return values. However, as a mutation tool with no annotations and incomplete behavioral disclosure, it's minimally adequate. It covers the basic purpose but lacks depth for safe and effective use by an agent.

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 parameters are well-documented in the schema. The description adds no additional meaning beyond implying the tool uses 'tab_id' and 'title' for renaming, which is already clear from the schema. Baseline 3 is appropriate as the 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 action ('renames') and target ('a tab in a Google Doc'), providing a specific verb+resource combination. However, it doesn't explicitly differentiate from sibling tools like 'update_doc_headers_footers' or 'modify_doc_text', which also modify Google Docs but target different elements.

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 no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing tab IDs from 'inspect_doc_structure', which is only hinted in the schema), exclusions, or contextual triggers for renaming tabs rather than other doc modifications.

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