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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered and the bar is lower. The description usefully discloses return content (fit, verification, and that terms are 'draft'), which matters because there is no output schema. It adds nothing on auth, rate limits, or whether the explanation involves additional cost or latency — notable for an 'openWorld' 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?

Front-loaded with the return content, then the brief toggle in a single short clause. The trailing legal/privacy consent boilerplate and the '(getMatch)' parenthetical do not help selection but occupy limited space, so the cost is small.

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 only two fully documented parameters and no output schema, the main burden is describing the return and the choice against siblings. Return content is covered, but the relationship to find_offers/get_offers and any notion of what a 'match' is relative to an offer remain unstated.

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%, so both parameters are already documented in the schema, including what brief omits. The description restates the brief behavior ('brief: true leaves the explanation out') without adding format or edge-case detail, and says nothing about match_id. Baseline 3 is appropriate.

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 states a specific resource and its detail content: a single match, why the offer fits the request, fit/verification, and draft terms. It is clear what the tool returns. However, it does not distinguish itself from siblings find_offers and get_offers, leaving the agent to infer that this is the per-match explanatory variant.

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?

No explicit when-to-use or when-not-to-use statement, and the siblings are never mentioned. Usage is only implied: you call it with a match_id to get that match's explanation, or set brief=true when you don't need explanations. That is enough to guess the case but not to choose confidently between it and find_offers/get_offers.

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