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

The description adds some behavioral context beyond annotations by mentioning 'OAuth/writeback safety notes,' which hints at authentication and write-safety implications not covered by readOnlyHint=false and openWorldHint=true. However, it does not provide concrete details about side effects, reversibility, or prerequisites, so the extra disclosure is limited.

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, dense sentence that front-loads the core action and lists key components without unnecessary words. Every phrase adds value, and the structure is efficient and scannable.

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 (10 parameters, no output schema, sparse annotations), the description is far too high-level for an agent to invoke correctly. It does not explain what a 'scaffold' entails, what 'column validation' involves, or how the sync policy is configured. It also fails to distinguish itself from many similar creation tools in the sibling list, making the missing context critical.

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 only 20%, and the description does not compensate by explaining any of the ten parameters. It mentions abstract concepts like 'source adapter' and 'sync policy' but does not map them to parameters such as adapter_mode or sync_direction, leaving the agent without meaningful parameter-level guidance.

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 uses a specific verb ('Create') and resource ('Google Sheets cue-table scaffold'), clearly distinguishing it from sibling connect_* tools that merely establish connections. It enumerates key deliverable components (source adapter, cue rows, column validation, sync policy, OAuth/writeback safety notes), making the tool's purpose unambiguous.

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, nor does it mention any prerequisites or exclusions. It does not reference sibling tools such as create_cue_sequencer or manage_cue, leaving the agent without a clear decision framework for selecting this tool.

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