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

The annotations already establish that this is not read-only, not idempotent, and not destructive. The description adds useful behavioral context on top: it records which rules were relied on, produces a public verification URL, and confirms the record can later be checked for tampering. It does not explicitly state that every call creates a new persistent record, but the signed, time-stamped, public-URL language is fairly clear.

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 compact and front-loaded: the main action appears first, followed by what the caller gets back, when to use it, and the subscription requirement. Every sentence contributes useful information with no repetition or filler.

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 no output schema, the description correctly explains the return value (record ID plus verify URL) and the authentication requirement, which are the main non-obvious details. It is complete for most calls, but it would be stronger if it also confirmed the public, immutable nature of the created record and explicitly distinguished itself from the control-attestation sibling.

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 the parameter descriptions already carry most of the semantic weight. The tool description adds only a high-level note about passing api_key and continuing required subscription, which is useful framing but does not substantially improve on the schema's own parameter details.

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 clearly identifies a specific verb and resource: it creates a signed, time-stamped attestation record of which Bidda rules were relied on for a decision. It even states the return values (record ID and public verification URL), making the purpose concrete. It does not explicitly contrast itself with the similar sibling 'create_control_attestation', which keeps it from a perfect score.

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?

The description gives useful context: it is for agents that must keep an audit trail, and it requires an active Bidda subscription or api_key. However, it does not explicitly say when to prefer this over other creation tools, and it never mentions create_control_attestation or any other alternative by name.

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