create_mobile_app_config

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

The [Write] tag adds minimal transparency beyond the annotations (readOnlyHint=false). No details on side effects, idempotency, or what happens on creation (e.g., if duplicates are allowed). The openWorldHint=true is not explained.

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 very brief, with two short sentences. While concise, the [Write] tag is redundant given annotations. It could be more structured, e.g., by including the return value or post-creation 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?

For a creation tool with 3 parameters and no output schema, the description lacks essential context such as what the created configuration looks like, whether it returns an ID, or any required prerequisites. It is incomplete for an agent to understand the full effect.

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 coverage is 67% (2 of 3 parameters have descriptions). The description does not add any additional parameter context beyond the schema. For the description parameter, no guidance is provided, and for branding_color, the schema already says 'Primary colour hex'.

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 action (create) and the resource (mobile app configuration). It is specific enough to distinguish it from sibling tools like get_mobile_app_config (read) or list_mobile_app_configs (list), though it lacks additional differentiation from other create tools for different resources.

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 explicit guidance on when to use this tool versus alternatives, such as whether to create vs update, or prerequisites like existing workspace. The description only states what it does, not when to use it.

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