List paid add-ons (offers)

list_offers
Read-onlyIdempotent

List the optional paid add-ons a maker can buy to promote their listing (name, one-sentence effect, price in USD). Listing is always free; these only ADD reach and are always labeled 'Sponsored'. Call this to see what's purchasable before create_checkout. During free early access (early-bird), offers are not yet purchasable and this says so (purchasable=false).

A4.5/5.0
Behavior4/5

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

Annotations already indicate a safe read-only, idempotent operation. The description adds valuable behavioral context: listing is always free, offers are labeled Sponsored, and during the early-bird phase the tool reports purchasable=false. No contradiction with annotations.

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

Conciseness5/5

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

Three sentences, front-loaded with the core action and output, followed by targeted usage and exception notes. No unnecessary filler.

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?

For a parameterless tool with an output schema, the description covers purpose, when to call it, market context, and a special state. Nothing critical is missing.

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?

With zero parameters and 100% schema coverage, there is no parameter burden. The description adds meaning by explaining what the returned offers represent, which is sufficient for this parameterless tool.

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?

The description clearly identifies the tool's action: listing purchasable paid add-ons (offers) that promote a listing, including what is returned (name, effect, price). This distinguishes it from siblings like create_checkout by defining it as the discovery step.

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?

Explicitly instructs the agent to call it before create_checkout to see what is purchasable. It also clarifies the early-bird exception (offers not purchasable yet), but does not name explicit alternatives or when-not-to-use cases beyond that.

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

A4.7/5.0
Disambiguation5/5

Each tool has a clearly distinct responsibility: search/fetch listing details, discover alternatives, submit a new tool, list paid add-ons, and create a checkout. Though list_offers and create_checkout are related, they serve sequential, non-overlapping steps with no ambiguity.

Naming Consistency5/5

All tool names follow a consistent snake_case verb_noun pattern: create_checkout, get_tool, list_alternatives, list_offers, search_tools, submit_tool. The verbs are descriptive and readable, and there are no mixed casing or naming style variations.

Tool Count5/5

Six tools is well-scoped for a directory/discovery server: search, detail, alternatives, submission, offers, and payment initiation. Each tool earns its place and the count feels neither thin nor overwhelming.

Completeness5/5

The server covers the core lifecycle: discovering tools (search_tools, get_tool, list_alternatives), adding new ones (submit_tool), and monetizing via add-ons (list_offers, create_checkout). No obvious dead-end or missing operation is apparent for the stated purpose.
