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

Annotations already declare readOnly, idempotent, non-destructive, and openWorld, so safety behavior is covered. The description adds useful quota information and a 'shows what happened before, not what will happen' framing, but 'directs you to the tool that does the work' is incomplete because the target tool is never named. This is not an annotation contradiction, but it is ambiguous.

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?

It opens with two sentences of legal disclaimer rather than the tool's function, then spends multiple sentences on scope exclusions. The core action is never stated crisply, so the structure is not front-loaded for an agent deciding whether to invoke it.

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?

There is no output schema, and the description never says what a successful check_risk result contains or which tool it points to. For a routing tool with zero required parameters, the destination tool and return shape are essential and missing.

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 100%, and the schema already documents keywords for cancelled records and notice_id for protest history. The description only loosely maps those domains to the parameters and adds no syntax or selection guidance beyond what the schema provides.

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 risk-signal categories (protest history, cancellation records, opportunity scoring), but it never states whether check_risk returns those records or merely routes elsewhere. The 'pointer tool' claim muddies the verb, and it does not distinguish itself from sibling tools like get_protest_history or search_cancelled_contracts.

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?

It explicitly excludes bid/no-bid, eligibility, certification, and related questions, and names explain_policy_boundary as the alternative for those cases. However, it gives no positive trigger for using check_risk over get_protest_history or search_cancelled_contracts, so the core routing decision is left to inference.

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