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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the trailing 'Read-only.' restates structured data rather than adding it. The description does contribute behavior-relevant framing by describing what is returned (holdings, offers, history), but says nothing about pagination, history window, or response size.

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?

Two short sentences, front-loaded with what the tool returns. The only waste is the trailing 'Read-only.', which duplicates the annotations and could be dropped.

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?

For a one-parameter, read-only, no-output-schema tool, the description covers the essentials of what comes back. It leaves open the history time window and whether results are truncated, which matter for an agent deciding between this and get_activity.

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?

Schema coverage is 0% — the single 'address' property has no description, only a regex pattern. The sentence 'Pass the connected wallet address' adds meaningful guidance (use the connected wallet, not an arbitrary address) which the schema cannot convey, but it does not address chain/network scoping or what happens with an address that has no positions.

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 names the resource concretely by enumerating its three return buckets: exercisable options, open/filled offers, and recent history. An agent can tell this is a per-address position snapshot, though the phrasing is a noun clause rather than a verb+resource statement and it never names the closest sibling (get_activity) that also returns history.

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 only directive is 'Pass the connected wallet address', which is a parameter hint rather than when-to-use guidance. Nothing says when to prefer this over get_activity, get_offer, or find_offers, so the agent must infer the boundary from names alone.

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