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

Annotations already declare a write operation (readOnlyHint=false), idempotency (idempotentHint=true), and non-destructiveness, so 'identical retries return the same receipt' largely restates the idempotency hint. The added value is 'It is accepted as recorded,' which signals no post-processing or validation, but auth requirements, failure behavior, and post-acceptance mutability remain unstated.

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?

Three short sentences with the action front-loaded and no padding. The middle clause 'It is accepted as recorded' is slightly cryptic, but nothing is wasted and the size suits a low-parameter tool.

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 a nested submission object, a required lease_token, and no output schema, the description omits the operational essentials: the run/lease lifecycle, enrollment key handling, and what the 'receipt' actually contains. Mentioning a receipt and idempotency is helpful but not sufficient for an agent to invoke this correctly on first try.

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 only 33% (essentially just agent_key), and the schema is deeply nested with lease_token, answer, context, isolation, and evidence sub-fields. The description's 'public evidence and honest limitations' only loosely gestures at the evidence and limitations fields and does nothing for run_id or lease_token, so it fails to compensate for the coverage gap.

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 states a concrete verb and resource: 'Record your typed answer with public evidence and honest limitations.' That is enough to separate it from read-oriented siblings like get_run or next_task. It stops short of naming the alternative action (e.g., release_run) or the lifecycle stage, so it is clear but not fully differentiated.

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 explicit when-to-use, when-not-to-use, or prerequisite guidance. The agent is not told it must first claim_run and hold a valid lease_token, nor how this relates to next_task or release_run. Only the implicit framing of 'your typed answer' hints at context.

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