apps_update

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

Annotations already indicate readOnlyHint=false, meaning mutation. The description's 'Patch' confirms mutation. No additional behavioral traits like permissions, idempotency, or side effects are disclosed. Minimal added value over annotations.

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, clear sentence with no filler. It is concise and front-loaded, though it could be slightly expanded to include more context without losing brevity.

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 presence of an output schema and the tool's simplicity, the description covers the basic purpose. However, it lacks guidance on prerequisites, error conditions, or the scope of the 'updates' object. Adequate but not comprehensive.

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% with descriptions for both parameters ('App name' and 'JSON body of fields to update on the app'). The description adds no further meaning beyond what the schema already provides. Baseline 3 is appropriate.

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 'Patch' and the resource 'existing Databricks App'. It distinguishes from siblings like apps_create (create new), apps_delete (delete), apps_deploy (deploy), apps_get (read), apps_list (list), apps_list_deployments (list deployments).

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 for updating an existing app, but does not explicitly state when to use this tool versus alternatives or when not to use it. No exclusions or context provided.

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