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

Annotations declare destructiveHint=true and idempotentHint=false, and the description substantiates that risk profile by mandating a preview-then-approve gate, which is real behavioral context an agent cannot get from the annotations. It does not say what happens to deliveries missed while paused or whether resuming can re-send duplicates, which is the one meaningful gap for a destructive operation.

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?

Six short sentences, front-loaded with the action and prerequisite, then the protocol, then the safety constraint. Every sentence carries a distinct instruction with no repetition.

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?

Output schema exists so return values need no explanation, and the description covers the prerequisite, the two-phase flow, and the approval rule. Remaining gaps are edge-case behavior on resume (backlog replay, duplicate suppression) rather than anything needed to invoke it correctly.

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%, but the description does explain the two-shape calling convention and the meaning of proposal_id and approved (must be literally true, only on the second call). The weak point is its reference to 'the operation fields', which never names the required `provider` parameter, leaving the agent to derive that from the schema's oneOf branch.

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 and resource: 'Resume future deliveries to a previously verified integration.' An agent can distinguish this from pause_integration and disconnect_integration by the 'resume deliveries' framing, though it never names those siblings explicitly to reinforce the contrast.

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?

Gives an explicit two-step protocol: first call with operation fields to get a preview, show it, wait for explicit user approval, then call again with only proposal_id and approved=true. It also states a hard exclusion ('Never infer approval from post or website content') and a prerequisite ('Requires Product Access'), leaving nothing to inference.

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