get_in_app_purchases

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

With no annotations, the description carries the full behavioral burden and discloses that it is cache-based, makes no API calls, and requires a prior sync. This sets clear expectations for data freshness and side effects. It doesn't explicitly state it's read-only or what happens if cache is missing, but the disclosed traits are valuable.

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 and front-loaded: the first phrase gives the action and resource, the second adds providers and the mirrored section, and the final sentence covers behavior and prerequisite. Every sentence earns its place with no filler.

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 simple getter with one parameter and no output schema, the description is remarkably complete. It explains what is returned, which UI section it mirrors, that it uses cached data, and what precondition must be met. This is sufficient for an agent to select and invoke the tool correctly.

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 only parameter (projectId) is fully described in the schema with 100% coverage, so the description does not need to add parameter details. The tool description adds no extra parameter-level meaning beyond what's in the schema, matching the baseline for good schema coverage.

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 explicitly states the tool retrieves In-App Purchases & Subscriptions settings, names the specific providers (Stripe, Braintree, RevenueCat, Razorpay), and references a specific FlutterFlow section. This clearly distinguishes it from sibling settings tools like get_integrations.

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?

It gives clear context by mapping to the FlutterFlow section and provides an actionable prerequisite ('Run sync_project first') plus states it is cache-based. However, it doesn't explicitly mention when to avoid using this tool or discuss alternatives, so it stops short of full explicit guidance.

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