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

With no annotations, the description carries the full burden of behavioral disclosure. It does disclose some behavioral traits: the answer will not name carrier/customer, will state what the archive holds, and will distinguish filings from coverage. However, it does not state what the tool actually returns, whether it is read-only, what happens on failure, or what 'verify' means operationally. The description is more about answer-interpretation than about tool behavior.

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?

The description is short and front-loaded with the verb phrase, but the remaining sentences are dense and abstract. They are not wasted words, but they are not clearly about the tool's purpose. The structure is acceptable for a short description, but the content is not well organized around what the tool does.

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 tool with no output schema and no annotations, the description should clarify what the tool does, what input it expects, and what the output means. It does none of these directly. The epistemic cautions are useful context for interpreting results, but they do not make the tool callable by an agent that does not already know what 'verify' means in this domain.

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%, so the description must compensate for the single 'fingerprint' parameter. It does not explain what a fingerprint is, what format it should take, or how it is used. The description only says 'Verify a Substradium fingerprint,' which adds minimal meaning beyond the schema's 'Fingerprint' title.

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 never states a concrete verb+resource. 'Verify a Substradium fingerprint' is the closest, but the rest of the description is a list of epistemic cautions ('The answer names neither...', 'A filing on record is not coverage in force') rather than a statement of what the tool does. It does not distinguish itself from siblings like carrier_record or coverage, and the name 'verify' is generic.

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?

There is no explicit guidance on when to use this tool versus the siblings. The description implies the tool is about verification of fingerprint-derived facts, but it never says 'use this when...' or 'for coverage lookups use coverage instead.' The cautions hint at interpretation rules, but not at selection criteria.

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