goldhold_checkpoint

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

With no annotations available, the description must carry the behavioral burden. It does state the side effect (saving state) and the benefit (seamless resume), but it doesn't disclose overwrite/versioning behavior, what data is included, or how the checkpoint is later retrieved.

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?

Two sentences, front-loaded with the action, and every clause adds value. There is no filler or redundant metadata.

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 tool is simple and the schema is self-documenting, but there is no output schema and the description omits the lifecycle context: how the checkpoint is stored/overwritten and which sibling tool should be used to resume. This is adequate but not complete.

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 schema already documents all four parameters. The description adds no parameter-level detail, landing at the baseline for high-coverage schemas.

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 operation ('Save a checkpoint') and the target resource ('current working state'), and adds a use-case ('enable seamless resume'). It doesn't explicitly name sibling alternatives like goldhold_resume or goldhold_plan_checkpoint, so it falls just short of full 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?

It gives concrete guidance on when to call the tool ('at natural breakpoints'). However, it doesn't mention when not to use it or how it relates to similar persistence tools like goldhold_plan_checkpoint, goldhold_store, or goldhold_restore.

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