set_cancel_at_period_end_scheduled_charge

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

With no annotations, description fully explains behavior: enabled=true stops cycle generator after next paid cycle while in-flight cycle continues; enabled=false reverses it. It also notes the mutation is reversible and not destructive, providing complete transparency.

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?

Three concise sentences: purpose, behavior, constraint. Front-loaded with key action, no unnecessary words. Every sentence earns its place.

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 simple toggle logic, 100% schema coverage, and no output schema, the description is complete. It explains what, when, how, and constraints, leaving no ambiguity for an AI agent to misuse the tool.

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?

Input schema covers 100% of parameters with descriptions. Description adds context by explaining the effect of enabled in terms of cycle generation after next paid cycle, which is not in schema. Slightly redundant but adds 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?

Description uses specific verb 'Toggle' and resource 'soft cancel on a recurring series', clearly distinguishing from hard cancel siblings like cancel_recurrence_scheduled_charge. It explains the exact behavior and mutual exclusivity with other recurrence options.

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?

Explicitly states when to use (to stop new cycles after next paid cycle), that it's reversible, and that it's mutually exclusive with recurrence.endsAfter and endsOn, giving clear guidance and alternatives.

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