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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds real value by disclosing the per-entry payload (status plus a transaction link) and the event taxonomy, but it leaves the window of 'recently', ordering, and result limits undisclosed — meaningful for a feed tool.

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 that identifies the subject first and then qualifies the event types. The parenthetical list is dense but each item carries information; nothing is redundant with the title.

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?

With no parameters, no output schema, and read-only annotations, the description covers what an agent needs: what the feed contains and what each entry looks like. Missing only operational details such as how far back 'recently' reaches and how many entries come back.

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 there is nothing for the description to disambiguate; the baseline for a no-param tool applies. The description correctly implies the feed is implicitly scoped to the link owner with no filtering arguments.

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 (the link owner's activity on FloorFeed) and enumerates the action types covered — buys, sales, offers, listings, mints, bridges, swaps — so the agent knows this is a historical activity feed rather than a holdings or alert tool. It stops short of explicitly naming which sibling (my_portfolio, my_calls, sales) to prefer for adjacent needs.

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 only implied: the word 'recently' and the event list suggest 'call this to see what the wallet has done lately.' There is no explicit when-to-use statement, no exclusions, and no pointer to alternatives among the many my_* siblings.

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