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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It indicates the tool submits an on-chain UserOperation (a write action) but does not detail gas requirements, reversibility, or side effects beyond staking.

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?

Two efficient sentences. The first sentence states core functionality, the second adds a critical prerequisite. No wasted words; the description is front-loaded and easily parsable.

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?

The tool lacks an output schema, and the description does not mention what the return value is (e.g., UserOperation hash). While it covers the action and prerequisites, it omits expected response details, which could affect an agent's follow-up actions.

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 coverage is 100% with descriptions for both parameters. The description adds value by specifying that `tokenAddress` must match a `fuse_get_staking_options` entry and clarifying that `tokenAmount` is in base units (wei). This goes beyond the schema.

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 explicitly states it submits an ERC-4337 UserOperation to stake a token using Fuse's staking module. It clearly distinguishes the action (stake vs. unstack) and resource, making it distinct from sibling tools.

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 advises listing staking options first with `fuse_get_staking_options`, providing a clear prerequisite. However, it does not mention when to avoid using this tool or alternatives, which would be helpful.

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