Transfer from

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the action ('transfer tokens') but fails to describe critical behaviors such as required permissions (e.g., approval from the 'from' address), whether the transfer is irreversible, potential gas costs, or error conditions. This is inadequate for a mutation tool with zero annotation coverage.

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, efficient sentence that gets straight to the point with no wasted words. It's appropriately sized for the tool's complexity and front-loaded with the core action.

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?

Given the tool's complexity (a token transfer with 4 parameters), lack of annotations, 0% schema description coverage, and no output schema, the description is insufficient. It omits essential details like parameter meanings, behavioral traits, and usage context, making it incomplete for safe and effective use.

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%, meaning none of the 4 parameters are documented in the schema. The description does not explain what 'address,' 'from,' 'to,' or 'value' represent (e.g., 'address' might be the token contract, 'value' in what units), failing to compensate for the schema gap. This leaves parameters ambiguous and hard to use correctly.

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 ('transfer tokens') and specifies it's done 'on behalf of another address,' which adds important context. However, it doesn't explicitly distinguish this from the sibling tool 'strato.tokens.transfer' (which likely transfers from the caller's own address), missing full sibling 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 like 'strato.tokens.transfer' or other token-related tools. It lacks any mention of prerequisites, context, or exclusions, leaving the agent to guess based on the name alone.

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