docs_batchUpdate

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 it 'Apply updates' which implies mutation/write operations, but doesn't disclose behavioral traits like required permissions, whether updates are reversible, rate limits, or what happens on failure. The description adds minimal context beyond the basic action.

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 includes helpful examples. Every word earns its place, making it easy to parse quickly.

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 no annotations, no output schema, and a mutation tool with 2 parameters, the description is incomplete. It doesn't explain what the tool returns, error conditions, or important behavioral aspects like idempotency or side effects. For a tool that modifies documents, more context is needed for safe and effective use.

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 both parameters (documentId and requests). The description adds marginal value by implying 'requests' includes operations like 'insert text, formatting, etc', but doesn't provide syntax or format details beyond what the schema suggests. 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 verb ('Apply updates') and resource ('to a Google Doc'), with specific examples of what types of updates (insert text, formatting, etc). It distinguishes from sibling tools like docs_create (creates new docs) and docs_get (reads docs), though not explicitly. It could be more specific about the 'batch' nature implied by the name.

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 on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing document ID from docs_get or docs_create), nor does it clarify when to use this versus other update tools like sheets_values_update or drive_files_update. The description implies it's for content/formatting updates, but this is not explicitly stated as a guideline.

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