generate_payment_link

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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, and the description complements these by specifying the return type (shareable URL) and noting that no email is needed upfront. It also includes post-payment instructions, adding value beyond annotations without contradicting them.

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?

Three precise sentences: first states purpose, second distinguishes from sibling, third provides pricing and actionable next step. No redundant or irrelevant information.

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?

Given one optional parameter, no output schema, and rich annotations, the description covers the tool's purpose, differentiation, pricing, and post-payment action. It lacks explicit mention of the link format or authentication requirements, but these are either implicit or covered by annotations.

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?

With 0% schema coverage, the description partially compensates by noting pricing for each enum option (paper=$29/mo, live=$99/mo). However, it does not explicitly explain the parameter name 'tier' or its default value, leaving some semantic gap.

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 explicitly states the tool returns a direct payment link for an AlgoChains subscription tier, using a specific verb and resource. It distinguishes from the sibling get_checkout_url by highlighting the pre-configured, shareable nature without email requirement.

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 clearly indicates when to use this tool (when a pre-configured, shareable link is needed) and contrasts it with get_checkout_url. It provides pricing for both tier options, aiding decision-making, but does not explicitly state when not to use it or mention other alternatives.

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