social_buy_blink

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

Discloses key behaviors: moves money, settlement on Solana, returns receipt and download link, checks price against spending caps. Since no annotations are present, the description fully carries the burden and does so thoroughly.

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?

Extremely concise (two sentences plus a short third) with no wasted words. Front-loaded with the core purpose, then adds behavioral details efficiently.

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?

Covers purpose, behavior, parameters, and return values well given no output schema. Minor gap: no mention of failure scenarios (e.g., insufficient funds, invalid link), but overall sufficient for a mutation tool.

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?

Adds significant meaning beyond schema: explains that the 'url' parameter accepts share links, actions URLs, or raw product IDs in the same form as social_get_blink; explains the 'email' parameter as optional for receipt, with anonymous purchase support and that the download link is returned regardless.

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?

Description clearly states the action ('Buy') and the specific resource ('product from a Solinkify Blink link as shared on X'). The verb is specific and the resource is well-defined, distinguishing it from sibling tools like datahub_buy which likely handle different types of purchases.

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?

No explicit guidance on when to use this tool over alternatives. The context 'as shared on X' implies it's for purchases initiated from social media Blinks, but no exclusion criteria or alternative suggestions are provided.

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