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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds that this is a generated (computed) report with optional scoping, but says nothing about aging bucket conventions (30/60/90+), point-in-time vs live data, or timezone handling of as-of dates.

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 well-formed sentence with the action and object front-loaded and the optional filter appended. No waste, though it is terse enough that it omits routing information it arguably has room for.

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?

There is no output schema, so the description carries some burden for explaining what the report contains, yet it never mentions the aging buckets or report shape. Combined with the 100%-covered input schema and read-only annotations, it is minimally viable but leaves the v1/v2 routing question unresolved.

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% (id, dateFrom, dateTo all documented with formats), so the schema already does the heavy lifting. The description only restates the date-range filter concept without adding format, default, or inclusive/exclusive semantics — baseline 3 is appropriate.

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 (Generate) and resource (aged receivables / AR aging report) scoped to a company. It is separable from get-aged-payables by resource name, but it never distinguishes itself from the sibling get-aged-receivables-v2, leaving ambiguity about which version an agent should call.

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?

'Optionally filtered by date range' hints at a use case but gives no explicit when-to-use, when-not-to-use, or alternative selection guidance. Critically, the existence of get-aged-receivables-v2 is never acknowledged, so the agent has no basis for choosing between the two.

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