Resume Chain

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

No annotations are provided, so the description carries the full burden for behavioral disclosure. It says the chain is resumed but does not mention side effects, idempotency, error conditions, or whether resuming triggers immediate execution. This is a significant gap for a mutating 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?

The description is a single, front-loaded sentence with no redundant wording. Every word adds value by specifying both the action and the target state, achieving maximum conciseness.

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 one parameter and an output schema, the description covers the basic invocation context adequately. However, with no annotations and no guidance on effects or prerequisites, it remains only minimally viable rather than fully self-sufficient.

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%, so the description must compensate for explaining chain_id, but it only adds that the chain is paused. The meaning of chain_id is largely inferred from the parameter name rather than explained, and there is no additional detail about format, ownership, or validation.

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 ('Resume') and a clear resource ('a paused chain'), which precisely identifies the operation. It also naturally distinguishes this tool from siblings like pause_chain and retry_now without needing extra explanation.

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 'paused chain' implies the tool should be used when a chain is paused seatbelt, but the description gives no explicit guidance about when not to use it or how it differs from retry_now or other alternatives. Usage is only implied, not stated.

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