Spl-token Transfer

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

Annotations already indicate write operation (readOnlyHint=false). The description adds that it optionally creates a recipient ATA and advises confirming parameters before writes. This is helpful but does not detail side effects or failure modes. No contradiction with 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?

Four sentences, but the second and third sentences are generic to the spl-token protocol rather than specific to the transfer tool. Could be trimmed to focus solely on transfer behavior.

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 existence of an output schema, the description covers the key aspects: token transfer between wallets, optional ATA creation, and parameter verification. It is adequate for an agent to invoke the tool correctly.

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 input schema has 100% coverage with descriptions for all 6 parameters. The description adds value by explaining the 'createAta' parameter's purpose and stressing verification of critical parameters (mint, decimals, etc.), going 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 clearly states 'Transfer SPL tokens between wallets' but later broadens to include deploy, mint, burn, freeze, thaw, and authority management, which are not the function of this tool. This misleads the agent about the tool's scope.

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 general guidance to use token tools with SAP payments but does not specify when to choose this transfer tool over sibling tools like spl-token_mintTo or spl-token_burn. No explicit when-not or alternative recommendations.

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