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

With zero annotations the description carries the full burden, and it does disclose real behavior: the verdict is returned byte-verbatim with scope attached, a computed pointer block is included, and the absent-verdict case yields an explicit typed NO_VERDICT sentinel rather than an error. It says nothing about permissions, read-only nature, caching/staleness, or cost, which matters for an unannotated trust lookup.

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 tight sentences with the core verb+resource front-loaded and the edge case trailing. Dense with useful terms ('byte-verbatim', 'scope', 'pointer block') but no filler; the jargon-heavy phrasing slightly reduces first-pass clarity.

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 one-parameter read tool with no output schema, the description conveys the return shape and the null case, which is the important part. It falls short on how to supply the 'product' identifier and on the trust/permission context implied by an unannotated tool in a verification family.

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 0% and the single required 'product' parameter is a bare string with no description. The description only echoes 'for a product' and never clarifies whether that identifier is a name, slug, SKU, or internal ID — the exact information the schema omits.

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+resource: fetching 'the current Verity bench verdict for a product,' plus what comes back (scope, pointer block). It is distinguishable from siblings like trust_status or trust_verify_receipt by resource, though it never names those alternatives. The domain term 'Verity bench verdict' is undefined jargon for an outside agent.

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 statement of when to call this versus trust_get_validation_record, trust_verify_receipt, or trust_status, and no preconditions (does the product need to exist? must it be resolved first?). 'No verdict returns typed NO_VERDICT' is return behavior, not usage guidance.

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