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

With no annotations, the description carries the behavioral disclosure burden. It does well by explaining the repayment source (settlement), the borrowing cap (one-third of escrow), and the dynamic limit that grows with repayment. It does not cover failure cases or what happens if the task never settles, but the core financial behavior is unusually transparent.

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?

Two sentences with no filler: the first front-loads the action and key constraint, and the second adds a meaningful dynamic rule. Every phrase contributes to understanding the tool's function.

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 financial mutation tool with no annotations, no output schema, and zero parameter documentation, the description is not sufficient on its own. An agent still needs parameter meanings, required preconditions (e.g., the borrower must have claimed the task), and likely failure behavior to invoke it 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?

Schema description coverage is 0%, so the description must compensate for undocumented parameters. It does not explicitly explain taskId, borrower, or wantedAtomic, and 'wantedAtomic' in particular is left ambiguous in units and semantics. The prose context helps infer that wantedAtomic is the requested credit amount, but the mapping to parameters is incomplete.

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 a specific action ('Borrow working capital'), a specific resource ('against a task you have claimed'), and adds distinctive mechanics: up to a third of the escrowed reward, repayment from settlement, and a growing limit. This clearly separates advance_credit from siblings like credit_account or claim_task even without naming 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?

The description implies when to use the tool: when you have claimed a task and need working capital. However, it gives no explicit guidance about when not to use it, no alternatives are mentioned, and there is no comparison to related financial tools such as credit_account.

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