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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the description doesn't need to restate safety. It adds real context beyond that: offers are scoped to the link owner (no wallet parameter, so no selection possible), they span two chains/marketplaces, and each price is rendered against the current floor with an interpretation rule.

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?

One front-loaded sentence naming the resource first, then the venue breakdown, then the floor-comparison semantics. Dense but every clause carries information; the parenthetical explanation of floor comparison is slightly verbose but earns its place.

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?

No output schema and no parameters, so the description must convey what comes back — it does, at the level of venue and price-vs-floor per offer. Minor gaps remain (currency/token detail, whether expired or accepted offers appear, result size), but an agent has enough to know when and how to call it.

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 tool takes zero parameters, so the baseline is 4 by rule. The description usefully confirms the implicit scoping — the owner is taken from the link, not supplied as an argument.

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?

States a specific resource and scope: open offers belonging to the link owner, broken out by venue (OpenSea collection/trait/item offers on Ethereum-style networks, Tensor on Solana). This clearly separates it from siblings like my_activity or my_alerts, which cover different object types.

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?

Usage is implied — check your outstanding offers and compare their price to floor — but there is no explicit when-to-use versus when-not guidance, nor a pointer to a sibling for related queries (e.g., historical/accepted offers in my_activity).

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