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

Annotations already declare read-only, idempotent, non-destructive behavior; the description adds that the result is deterministic and signed, which is a genuine extra behavioral trait. However, it does not explain the signature's role, failure modes, or assessment semantics, so the contribution is modest.

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 short, but the opening clause is a verbatim repeat of the title and the remaining clause is too generic to carry meaningful information. This reads as under-specification rather than disciplined conciseness.

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 a required `receipts` input, a large sibling tool set, and no prose guidance, an agent cannot reliably determine what to pass or when to select this tool. The output schema and annotations cover some safety/return expectations, but the core invocation and routing questions are entirely unanswered.

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?

The schema names a required `receipts` field but provides no property description, and the phrase 'supplied input' is a placeholder that adds no meaning. The 100% schema-description coverage does not help because the schema itself contains no real parameter documentation.

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 first clause simply restates the tool's title. 'Deterministic signed assessment over supplied input' names a generic action but not what the tool actually bundles, assesses, or returns, and it does not distinguish this from the many sibling receipt/bundle/evidence tools.

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?

No guidance is given for when to use this tool versus alternatives such as agent_task_handoff_receipt, cross_protocol_receipt, or multi_source_fact_bundle. There are no conditions, prerequisites, or exclusion criteria.

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