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

With no annotations, the description carries the full behavioral burden and does so thoroughly: read-only, writes/signs/executes nothing, tenant sourced from configuration rather than an argument, and explicit OK/REFUSED/UNAVAILABLE outcome semantics with a no-fabricated-data guarantee. It also flags the version precondition that yields UNAVAILABLE and the caveat that a readout is not a compliance finding.

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?

Purpose is front-loaded in the first sentence and most sentences carry distinct information (safety, config prerequisites, status semantics, version gate). There is mild redundancy — 'the records you supply' is repeated and the read-only guarantee is stated twice in spirit — but no padding is serious.

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?

Failure modes and safety are well covered and the output schema means return values needn't be explained, but for a tool whose only input is a free-form nested object, the description leaves the request payload entirely unspecified. An agent can understand the tool's behavior yet still not know how to construct a valid call.

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 'request' parameter is an opaque nested object with additionalProperties: true, so the schema tells an agent nothing about what to pass. The description adds only a negative constraint (tenant is never an argument) and the vague phrase 'the records you supply' without naming fields or shape.

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 a specific resource and output: a 'readiness report for one oversight case, computed from the records you supply.' That is clear enough to distinguish it from evidence-fetching siblings, but it never contrasts itself with them (get_decision_evidence, verify_receipt, gate_decision) and leaves 'readiness' somewhat abstract.

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 lists prerequisites (TRUST_GATE_API_URL/API_KEY/TENANT_ID, a compatible API version) but gives no when-to-use versus when-to-use-a-sibling guidance across a large family of TrustGate tools. An agent must infer on its own whether to inspect a case, verify a receipt, or replay a decision.

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