Signed self-contained audit evidence package with a Merkle root (PAID $4.00)

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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false, and destructiveHint=false. The description usefully adds that the route is paid ($4.00 USD via x402/base/usdc on eip155:8453), but it does not explain side effects, authentication needs, or whether a persistent record is created.

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 definition is short and front-loads the core artifact plus the remote payment route. The first sentence largely repeats the title, which is minor waste, but the overall structure is efficient.

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?

An output schema exists, so return values need not be explained, but the input side is almost entirely undocumented across seven parameters and there is no routing guidance among numerous siblings. For a paid open-world tool with non-idempotent semantics, the description is not complete enough for reliable invocation.

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?

There are seven input parameters and schema description coverage is 0%; the description provides no meaning for as_of, period, policy, subject, artifacts, assertions, or attestations. With the schema supplying only titles and defaults, the description completely fails to compensate for the missing parameter semantics.

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 the artifact produced: a signed, self-contained audit evidence package with a Merkle root, and it adds the paid remote route. It does not explicitly differentiate this from evidence-related siblings such as v1_evidence_ingest, v1_evidence_query, or v1_bureau_audit, but the resource itself is clear.

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 endpoint and payment details but no guidance on when to use this tool versus the many audit/evidence/receipt siblings. It states that the route is paid, but does not describe prerequisites, when-not-to-use conditions, or alternatives.

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