sui_get_latest_checkpoint

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

There are no annotations, so the description carries the full burden of behavioral disclosure. It only states what the tool does without revealing return format, potential errors, or any other behavioral traits. While being a read-only getter is implied, the description does not explicitly confirm this or provide additional 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 a single, concise sentence that directly conveys the tool's purpose without unnecessary words. It is well-sized for the simplicity of the tool.

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 description is minimally adequate for a parameterless getter, but it does not elaborate on what 'checkpoint information' includes (e.g., sequence number, timestamp, digest). With no output schema or annotations, a bit more detail would improve completeness, but the tool's simplicity keeps it from being critically insufficient.

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 tool has zero parameters, and the schema coverage is effectively 100% since there are no properties. Per the guidelines, a baseline of 4 is appropriate when there are no parameters to document; the description does not need to add parameter semantics.

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 tool's function with a specific verb ('Get') and a specific resource ('latest checkpoint information'). It is unambiguous and distinct from sibling tools, which focus on balances, objects, transactions, and other Sui data, none of which directly relate to checkpoints.

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 usage when one needs the latest checkpoint, but there is no explicit guidance on when to use this over alternatives or any context about suitability. Given the tool's simplicity, the implied usage is acceptable but not clearly articulated.

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