Quote the price of an app in USD and FLUX

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

With no annotations provided, the description carries the full behavioral burden and largely succeeds: it discloses the conditional update path, the credit for the unused current term, and the USD/FLUX market-rate pricing. It still does not state permissions, side effects, or whether the call is strictly read-only, but the quote semantics and update-credit behavior are unusually well surfaced.

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 front-loaded sentences with no waste. The pricing behavior and conditional update logic are presented compactly and in the right order.

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 quote tool with a complex nested spec and no output schema, the description gives enough return-value context by stating that the result is in USD with a FLUX amount at market rate, and it covers the update-credit behavior. It is less complete on auth or dry-run guarantees, but the core quoting contract is clear.

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?

The schema description coverage is reported as 0% for the single top-level parameter, and the description adds no meaningful detail beyond calling it a 'given specification.' It does not explain required nested fields, defaults, or constraints, so it fails to compensate for the low schema description coverage.

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 states a specific verb and resource: it returns the Flux Cloud price for registering or updating a given specification. It clearly separates this quote operation from deployment or general pricing tools by tying the price to the app spec and the existing-app update case.

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 explains what the tool does but gives no explicit guidance on when to use it versus alternatives such as flux_get_pricing, flux_build_spec, or flux_deploy_app. The agent must infer that this is a pre-deployment quoting step.

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