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

With no annotations, the description carries the full burden and adds only cost information ('FREE, unlimited'). It says nothing about whether attestations are permanent/irreversible writes, what permissions or identity are required, whether the call is atomic, or what happens on partial failure.

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?

Two short sentences, front-loaded with the action and scope, followed by the cost signal. Zero 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?

An output schema covers the return value, but for a write-oriented batch tool with no annotations the description omits the eligibility rules, the batch-atomicity behavior, and the sibling relationship. It is not sufficient for an agent to call it safely without guessing.

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% and there is only one parameter, so the baseline is 3. However, the attestation object is free-form (additionalProperties: true) and the description gives no hint about its required fields, which is precisely the detail the schema cannot supply.

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?

States a specific verb ('Attest') and resource ('a batch of completed work items') with the batch qualifier made explicit. It does not name the obvious sibling mint_attest, so the single-vs-batch distinction is only implied by the word 'batch'.

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 on when to choose this over mint_attest, no preconditions (must the items already be registered? must the caller have joined a cell?), and no note on partial failure handling. The phrase 'completed work items' hints at a precondition but is never spelled out.

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