A4.4/5.0
Behavior4/5

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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered; the description adds genuinely new context: no inputs, no side effects on quotes/orders/payments, per-entry automated-ordering flag, and that quoteMode manual entries must be priced via their quoteUrl rather than here. That is real behavioral disclosure beyond the annotations, though it doesn't discuss caching or freshness of the prices.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with what is returned, then scope notes, then the negative constraint. The object-beta explanation takes two sentences and is slightly heavier than needed, but every sentence carries information an agent would otherwise have to guess.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no parameters and no output schema, the description carries the full burden and meets it: it enumerates the service channels, describes the per-entry fields conceptually (automated ordering availability, starting price, quoteMode/quoteUrl), and flags the custom-priced beta. An agent knows what comes back and what not to expect.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Zero parameters, so the baseline is 4; the description correctly states 'Takes no input,' which is consistent with the empty schema. There is nothing further to document.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource: returns channel availability and starting prices for a named list of services (fax, letters, certified mail, postcards, handwritten cards, paper checks, plus the object beta). An agent can distinguish this catalog/availability lookup from siblings like postedly_products, postedly_quote and postedly_checkout without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives clear usage context and explicit exclusions: 'Takes no input. Does not create a quote, order or payment,' which routes an agent toward the quoting/ordering siblings when that is the actual goal. It stops short of naming postedly_quote explicitly as the alternative for quoteMode manual entries, so the routing is implied rather than stated.

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