get_mobile_app_blueprint

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

No annotations are provided, so the description bears the full burden of behavioral disclosure. It only states the output intent ('generates blueprints') without any mention of side effects, whether the tool is read-only, what the response format is, or if any state is stored. Given that the tool name starts with 'get', it likely reads/generates data, but this is not explicitly stated, and there is no information on output structure or delivery.

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, front-loaded sentence that efficiently conveys the verb, key deliverables (layouts, navigation stacks, UI blueprints), and target frameworks. There is no filler or redundant information. It is appropriately sized for the tool's simplicity.

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?

With no output schema and no annotations, the description must explain what an agent can expect from the call. It does not describe the return value (e.g., JSON, code, diagram), any prerequisites, or behavior such as rate limits or authentication. While the tool has only two parameters, an agent cannot fully anticipate the result or any constraints, making the description incomplete for safe and correct invocation.

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 schema already provides complete descriptions for both parameters (framework and screen_type) with enums, giving 100% coverage. The description adds minimal semantic value beyond what the schema indicates — it mentions the concrete frameworks and screen types, but those are already enumerated in the schema. Since the schema covers everything, the baseline is 3, and the description does not exceed it.

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 a specific verb ('Generates'), the resource ('production mobile app screen layouts, navigation stacks, and UI blueprints'), and the target frameworks (React Native/Expo, Flutter). It is distinct from sibling blueprint tools like get_ui_component_blueprint (individual components) and generate_fintech_trading_blueprint (fintech-specific), so an agent can tell them apart.

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 provides no explicit guidance on when to use this tool versus alternatives. It does not mention exclusions, conditions, or refer to sibling tools. An agent must infer from the name that this is for mobile app blueprints, but there is no direction on choosing it over more specialized blueprints (e.g., fintech trading) or UI component blueprints. This is a significant gap.

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