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

No annotations are provided and the description carries the full burden, yet it discloses nothing about behavior: no mention of whether it is read-only, what it returns, error handling, or side effects. A one-line tautology provides zero behavioral context.

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 not concise but vacuous: a repeated restatement of the tool name. It is not front-loaded with meaningful information because there is no meaningful information to front-load.

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 3-parameter tool with no annotations and no output schema, the description is completely inadequate. It provides no purpose, no usage context, no behavioral traits, and no parameter guidance beyond what the schema already shows.

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 100%, so the three parameters (step, start, value) are already documented in the schema. The description adds no additional parameter meaning, but the baseline for full schema coverage is 3.

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 is a pure tautology: 'Step Function: Step Function'. It restates the tool name twice without stating what the tool actually does, what kind of step function it computes, or what resource it operates on. An agent has no way to distinguish it from the hundreds of x402-* siblings.

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?

There is no indication of when to use this tool, when not to, or which siblings are alternatives. The title is null and the description offers no context, so the agent cannot route to this tool over any other.

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