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

The annotations already establish that this is a read-only, non-destructive, idempotent, non-open-world operation. The description adds useful return-shape details and a failure mode ('Depot doesn't cover X yet'), but it does not cover permissions, rate limits, or other behavioral context beyond output fields.

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?

The description is short and avoids wasted prose, but it is densely compressed into cryptic fragments and output-field lists. It is not front-loaded with a clear purpose, which makes the compactness work against readability.

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?

This is an 11-parameter tool with no output schema, so the description needs to carry significant explanatory burden. It partially describes the return shape and one volume behavior, but it leaves most parameters and the overall usage context incomplete.

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 only 64% across 11 parameters, so the description must compensate, but it only gestures at 'task,' 'stack context,' and 'volume.' It leaves compact, pricing, sender, existing, framework, maxMonthly, noUsageBilling, and maxPriceAgeDays unexplained in prose.

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 implies the tool takes a task in words and returns a recommendation with pick, runner-up, price, free option, and rationale, but it never states the core purpose in a clear verb+resource form. It is more an output-shape sketch than a purpose statement, and it does not distinguish itself from siblings such as decide, compare, or quote.

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?

There is no explicit guidance on when to use this tool instead of alternatives. The title calls it a 'front door,' but the description does not say when this one-call answer is preferred over sibling tools or what circumstances should route elsewhere.

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