fonzip_monthly_donations

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

Annotations already indicate readOnlyHint=false, idempotentHint=false, and destructiveHint=false, and the description merely lists mutation-like operations without adding side-effect context. It does not explain what cancellation triggers, whether approval flows are required, or what consequences follow a card update request or amount change.

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 compact sentence with the resource scope front-loaded and a list of core operations. It is efficient, though for a 32-parameter multi-action tool it could be structured into clearer action groups.

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 high complexity (32 parameters, one required action, nested objects, no output schema), the description is too sparse. It does not explain how the required 'action' parameter routes to modes like change_values, cancel, create_update_request, respond_amount_change_request, or send_card_update_request, nor does it mention omitted operations such as date/category changes and retry.

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%, so the schema already documents every parameter. The description adds no extra parameter meaning beyond naming some high-level operations, which keeps it at the baseline rather than adding value.

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 names the resource ('Duzenli (aylik) bagislar' / recurring monthly donations) and lists concrete operations: creating/responding to amount change requests, sending card update requests, and canceling recurring donations. However, it omits some distinct modes present in the schema, such as changing the next withdrawal date, category, retry withdrawal, and the broader action-dispatch model, so it is not fully precise.

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 gives no guidance on when to use this tool versus sibling tools like fonzip_donations or fonzip_membership_dues, and no when-not-to-use conditions. It implies the domain via the resource name but never states selection criteria or alternatives.

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