Review or recover an account transaction

otto_sponsored_account

Destructive

Protected account action: availability, prepare, reviewGas for current gas payer and estimate, explicit submit, owned read or reconcile. Gas refresh is read-only planning and requires new confirmation before any send. Wallet upgrade is separate. Sponsorship requires a reviewed source activation; current availability is authoritative. A missing submission response is unknown and must never cause a replacement submission.

B3.4/5.0

Behavior4/5

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

Annotations already cover the safety profile (destructive, non-idempotent, open-world), so the bar is lower, and the description adds real value beyond them: gas refresh is a read-only planning step requiring fresh confirmation, and critically 'a missing submission response is unknown and must never cause a replacement submission.' That idempotency caution is exactly the kind of hazard disclosure annotations can't express.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a dense, list-like block with no wasted filler and the protected-action framing is front-loaded, but it reads as terse internal jargon rather than structure an agent can parse order-of-operations from.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists so return values needn't be explained, and annotations carry the safety profile. What remains unclear for a complex multi-mode mutation tool is how the agent selects a mode and what each requires, which the description only partially covers.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema declares zero parameters (empty properties, additionalProperties true), so baseline is 4. The description compensates somewhat by naming the action modes that function as an implicit selector, though it never states that selection is how inputs are chosen.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description identifies this as a 'Protected account action' and enumerates modes (availability, prepare, reviewGas, submit, owned read, reconcile), so the agent knows the domain. But it is opaque jargon that never cleanly states the resource or verb, and it does not distinguish this multiplexed tool from the many otto_* siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives some routing: 'Gas refresh is read-only planning and requires new confirmation before any send' and 'Wallet upgrade is separate', which steers the agent away from a related action. However, it never names an alternative tool or states explicit when-not conditions for the remaining modes, leaving usage largely implied.

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