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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing: no permissions required, no mutation semantics, no idempotency, no cost mechanics beyond mentioning 0.003 USDC, and no explanation of what the three state distinctions mean operationally.

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 single sentence is short but not front-loaded with a purpose—it opens with an abstract list of states before the reader knows what the tool does. The trailing '0.003 USDC' is the only concrete detail and feels disconnected from the rest.

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 tool with two required nested-object parameters, 0% schema coverage, no annotations, and no output schema, the description is far too thin. An agent cannot determine what to pass or what it will get back.

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% and both parameters are required nested objects (action.kind, record.record_id, record.content_sha256). The description mentions content and evidence hashes but does not map them to parameters or explain valid action kinds, leaving the schema entirely undocumented.

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 lists concepts (requested, operator-completed, evidence-verified states) but never states a clear verb+resource. 'retention_deletion_receipt' plus a sentence fragment describing states makes it hard to tell whether this creates a receipt, verifies one, or reports status. It does not differentiate itself from siblings like delivery_evidence or verify.

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 when-to-use guidance, no when-not-to-use, and no mention of alternatives such as delivery_evidence, attest, or verify. The agent must infer the situation from the description alone, which is not possible with confidence.

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