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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds value beyond that by naming the domain (Sepolia resources), the returned fields (id, title, URL), and the behavior when the query is omitted. It does not mention result limits or pagination, which is the only real gap.

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 sentences ordered by usefulness: purpose and routing first, input meaning second, return shape and exclusions last. Every clause carries distinct information with no restatement of the name or 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?

The tool is simple (one optional param, no output schema), and the description covers purpose, input, return fields, and scope, which is sufficient to invoke it correctly. The only omission is whether the unfiltered listing is bounded or paginated, a minor gap for a single-param read.

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 100% and the schema already defines query as optional words from name, path, or address and states that omitting it lists every resource. The description restates this without adding format, matching, or ranking semantics, so it neither compensates for nor exceeds the schema. Baseline 3 applies.

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 verb and resource ("find a resource id") and immediately names the two downstream siblings it feeds (get_quote, negotiate_price). The closing clause "Does not quote, negotiate, or pay" draws a hard boundary against those siblings, so the agent can separate them without opening schemas.

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?

Gives an explicit when: use it to obtain a resource id before quoting or negotiating. Gives an explicit when-not: it does not quote, negotiate, or pay. Also states the omit-query behavior (list everything for sale), so both the filter and no-filter paths are covered.

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