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

Goes well beyond the annotations by disclosing exactly what is mutated (clears next_payment_due_date and is_overdue) and that the change is transient because both repopulate on the next Plaid liabilities sync. That reversibility/regeneration detail is precisely the kind of behavioral context annotations don't supply, and nothing contradicts the hints.

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?

Front-loads the one-line purpose, then conditions, effects, args, and returns. Every sentence earns its place, though the blank-line-separated Args/Returns scaffolding is slightly more verbose than needed for a single-parameter 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?

For a narrow mutation tool with annotations covering safety and no output schema, the description is complete: it explains the trigger, the exact fields cleared, the regeneration behavior, the sole argument, and the return shape. Nothing an agent needs to call it correctly is missing.

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% and the single parameter (account_id) is undocumented in the schema, but the description compensates by explaining it is the Account.id whose warning should be cleared. Good compensation; minor room for the expected id format.

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 (dismiss) plus resource (past due payment warning) and scope (on a debt account). It is clearly distinguishable from siblings like confirm_debt_payment_match, reject_debt_payment_match, and dismiss_budget_recommendation.

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?

Gives a concrete triggering condition: dashboard shows past due but the user knows the Plaid data is wrong (e.g. paid offline, not yet picked up). This is strong when-to-use guidance, though it names no explicit alternative tool or exclusion.

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