create_off_cycle_payment

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

Annotations only carry a title, so the description bears the full behavioral burden. It does not disclose that this is a write/mutation, whether it requires approval, whether it is idempotent, or what happens on failure. For a payment-creation tool this is a meaningful gap.

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?

A single sentence with no waste, front-loaded with the verb and resource. It is appropriately sized, though minimally so for a 6-parameter mutation tool.

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 full schema coverage the parameters are covered, and there is no output schema to explain. However, for a financial mutation tool with no annotations, the description omits essential context about approval flow, permissions, and side effects, leaving it only minimally viable.

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 amount, reason, currency, contract_id, description, and payment_date. The description's parenthetical reason examples add nothing beyond the enum already present in the schema. Baseline 3 applies.

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?

States a specific verb+resource ('Create an off-cycle payment') and enumerates example reasons (bonus, commission, reimbursement). It is distinguishable from create_payment and approve_off_cycle_payment by name, though the description does not explicitly contrast them.

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 when-to-use guidance, no prerequisites (e.g. contract must exist, permission needed), and no mention of the sibling approve_off_cycle_payment that logically follows. It does not say when an off-cycle payment is appropriate versus a regular payment.

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