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

With no annotations, the description carries the full burden and does reasonably well: it discloses the auth mechanism (workspace key via _meta[satledger/api-key] or X-API-Key), the transport, that the operation is free and permanent, and that verification runs customer-side. It does not address idempotency, side effects, or limits on bundle size, keeping it short of a 5.

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 text is dense and front-loaded with the action, the return content, and the auth requirement in the first two sentences. Minor redundancy: 'free' appears in the first sentence and again as 'Free, permanently.' The telegraphic style is efficient overall.

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?

There is no output schema, so the description must describe returns, and it does: a summary plus the archive URL. It also covers authentication, cost, and the meaning of the optional expectation parameters. Given four parameters and no annotations, this is nearly complete, missing only edge-case behavior such as failure modes or bundle size.

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 only 25% (only api_key is documented in the schema), so the description must compensate. It supplies the rationale and source for expect_action_head/expect_action_count ('from state YOU kept to check completeness'), which the bare schema does not convey, and echoes the api_key auth path. agent_id is left unexplained, though its meaning is self-evident.

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 names specific verbs and resources: build the export bundle, run the customer-side verifier, and return the summary plus archive URL. This is unambiguous and clearly distinct from siblings like list_agents or record_action, though it never explicitly names an alternative tool. Purpose is clear without sibling routing.

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?

It gives operational guidance on one parameter (pass expect_action_head/expect_action_count from state you kept, to check completeness), which implies the tool's use case is post-hoc verification of an agent's action history. However, there is no explicit when-to-use vs when-not-to-use guidance and no named alternative among the 13 siblings. Usage is implied rather than stated.

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