smart_update_webapp

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 'automatically identify and update' but does not disclose what 'update' entails (e.g., whether it creates a new version, overwrites deployment code, or modifies settings). No mention of side effects or permissions required.

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, concise sentence with no unnecessary words. It includes an emoji for visual emphasis and is front-loaded with the key action. Every part earns its place.

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 simplicity (two parameters, no nested objects, no output schema), the description is adequate but incomplete. It does not explain what the return value is, what triggers the 'automatic identification,' or how it differs from manual deployment updates. More context would be helpful.

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%; both parameters have clear descriptions (script_id: 'Apps Script project ID', version_description: 'Version description (optional)'). The tool description does not add additional meaning beyond the schema, so baseline score of 3 applies.

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's purpose: 'automatically identify and update the latest web app deployment (recommended).' The verb 'identify and update' and resource 'latest web app deployment' are specific, and the tool distinguishes itself from siblings like deploy_webapp or update_webapp_deployment by being automatic and recommended.

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 by calling it 'recommended,' but it does not explicitly state when to use or when not to use this tool versus alternatives like update_webapp_deployment. No context about prerequisites or conditions is provided.

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