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

With no annotations, the description carries full burden. It discloses that the tool submits a signed transaction and mentions a 'structural re-verifier' that pins ATA creation instructions and allowlist, hinting at validation. However, it does not explain what happens on success/failure, whether it blocks, or other side effects.

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 two sentences with no redundancy. The first sentence states the core function, and the second adds key context about verification. Every part earns its place.

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 simple submit tool with two parameters and no output schema, the description is mostly complete. It explains the transaction type and mentions verification. However, it could clarify the return value or state changes, and the linkage to the build tool is implied but not explicit.

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 clear parameter descriptions. The tool description adds context by specifying that the transaction is for ATA creation and mentioning the re-verifier, which enhances understanding of the 'signedTransaction' parameter 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 the verb 'Submit' and the resource 'ATA-create tx', specifying that it handles a wallet-signed transaction for creating an associated token account. It distinguishes itself from sibling tools like 'build' and 'list' by focusing on execution.

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 implies a build-then-execute workflow by referencing 'the matching /build call' and instructing the agent not to submit the transaction manually. However, it does not explicitly state when to use this tool versus alternatives (e.g., other execute tools), and lacks explicit when-not-to-use guidance.

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