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

Annotations only declare readOnlyHint=false, openWorldHint=true, destructiveHint=false; the description adds real substance beyond that – uncertain receipts stay unchanged, no mutation is replayed, only a proven match advances the workflow, and audit-only failures are safely repeatable (idempotency guidance). readOnlyHint=false is consistent with the review advancing workflow state without replaying mutations, so no contradiction. It still doesn't say what the verification response contains.

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 tight sentences, front-loaded with the action and followed by outcome and retry semantics; every clause carries meaning. Some domain jargon ('receipts', 'audit-only failures', 'native checkpoint') is unexplained, which costs a point.

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 one-parameter recovery tool with no output schema, the description covers safety and idempotency well but omits the meaning of workflowId and offers no indication of what a verification result looks like. Adequate, but with clear gaps an agent would notice at call time.

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% for the single workflowId parameter, so the description must compensate and largely doesn't. Only indirectly does 'interrupted study block' hint at what the ID identifies; no guidance on where to obtain the workflowId or that it must reference a suspended block.

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 uses a specific verb+resource: 'Independently verify an interrupted study block from its saved native checkpoint.' That distinguishes a review/recovery step from the plan/prepare/run siblings. It does not explicitly differentiate itself from goodnotes_review_study_collection or goodnotes_review_study_revision, so it falls short of a 5.

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?

The phrase 'interrupted study block from its saved native checkpoint' implies the trigger condition (recovery after interruption), and 'Audit-only failures can be safely repeated' gives a retry rule. However, the definition never states when to prefer this over status/prepare/run siblings, or what preconditions the workflowId must satisfy.

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