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

Annotations already establish read-only, idempotent, non-destructive behavior, so the description's job is to add context, and it does: it discloses the returned fields (date, official source link, incident count, anonymized summaries), states that identifying details like initials and ages are stripped, and warns the content is not a court finding. It omits any note on ordering, pagination, or how far back the stored archive goes.

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 compact sentences plus a short legal caveat, all front-loaded with the core action and scope before the return details. Nearly every clause earns its place; only the anonymization detail and disclaimer could be tightened, but both are substantive.

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 single-parameter read tool with rich annotations and no output schema, the description covers what is returned, how the data has been sanitized, and a caveat on interpretation. The only meaningful gap is behavior of the limit/ordering and the archive's time depth, which an agent might want before calling.

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 description coverage is 0%, but there is a single parameter named "limit" whose type and 1–50 bounds (default 20) are fully expressed in the schema, so little compensation is needed. The description never mentions the limit parameter or what "recent" means for ordering, so it adds no real meaning beyond the structured field.

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 ("List recent public MVR bulletins") plus the important qualifier that they are "already stored by FinPortal," so the agent knows this reads cached curated data rather than fetching live. It does not explicitly name a sibling alternative, but the MVR source is distinctive enough against the news/filing siblings to be recognizable.

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: "already stored" signals a local, pre-collected corpus and "recent" implies a recency-ordered listing, but there is no explicit when-to-use versus alternatives (e.g., get_domestic_news or get_latest_news) and no exclusions. The closing caveat about reports not being final court findings is a useful usage warning but not routing guidance.

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