Continue a handed-off conversation

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

Annotations already declare readOnlyHint=false and idempotentHint=false, indicating a mutating, non-idempotent operation. The description adds that it stores a new conversation and links it back to the original, which is useful. However, it does not disclose potential side effects like token invalidation or whether the original handoff remains usable, leaving gaps in behavioral transparency beyond the annotations.

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, concise sentence that leads with the primary action ('Redeems a handoff') and flows into the significant consequence ('stores the continuation as a new conversation'). It is front-loaded and avoids fluff. It could be slightly more structured, but overall it is appropriately compact for its lack of parameter details.

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?

With five parameters (three required) and zero schema coverage, the description is far from complete. It omits any explanation of what the parameters mean, how the tool behaves in edge cases, or what the return value or errors might be. The absence of an output schema heightens the need for behavioral detail, which is missing. The only complete element is the high-level flow of redeeming and storing.

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?

The schema description coverage is 0%, meaning the description provides no information about the token, provider, messages, app, or title parameters. Since the description does not compensate for this absence, an agent cannot infer the meaning or format of the parameters. The schema constraints alone do not explain semantics (e.g., what format token is, what provider refers to, how messages are structured).

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 clearly states the action: redeems a handoff and stores the continuation as a new conversation linked to the original. This distinguishes it from a generic 'redeem' operation by specifying the storage behavior. However, it does not explicitly contrast with sibling tools like redeem_handoff, so it falls short of full differentiation.

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 description provides no guidance on when to use this tool versus alternatives such as redeem_handoff or save_conversation. It lacks explicit context about the intended use case (e.g., 'use this when you want to continue a conversation from another client'). The usage scenario is only implied by the name and title.

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