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

Annotations already provide basic safety traits. The description adds value by specifying the PATCH method and partial update behavior. However, it does not disclose authorization requirements or other side effects beyond what annotations offer, which is acceptable given annotation coverage.

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 extremely concise: one sentence with a clarifying parenthetical. Every word contributes meaning. It is front-loaded with the action verb and efficiently communicates the core behavior.

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 schema coverage (100%), annotations, and no output schema, the description is sufficient. It captures the essential behavior (PATCH update of specific fields). It could optionally include an example or note about return value, but that is not required.

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?

The input schema provides full descriptions for all 4 parameters, so the baseline is 3. The description adds no additional parameter-level information, but the schema already covers max length and JSON format.

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 'Update' and the resource 'mobile app group', specifies what can be updated ('name or apps list'), and includes the HTTP method 'PATCH' with partial update semantics. It effectively distinguishes from sibling tools like create and get.

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 specific fields of an existing mobile app group. It does not explicitly state when not to use or list alternatives, but the context of sibling tools (create, get, list) makes the intended use clear.

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