checkpoint

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

The description only says 'Create', implying a write/mutation operation, but it lacks details on side effects, prerequisites, or behavioral traits (e.g., whether creating a checkpoint affects state or requires certain permissions). Since annotations are absent, the description should provide this 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 extremely concise (6 words) but fails to deliver substantive information. It is more under-specified than concise; the single sentence does not add value beyond the tool name.

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 three parameters, no output schema, and many sibling tools, the description is wholly insufficient. It provides no information about return values, side effects, or how 'checkpoint' fits into a larger workflow.

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 0% and the description does not mention any parameters. The three parameters (status, summary, nextActions) have no explanation of their meaning or usage, leaving the agent with only the parameter names.

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 states the tool's purpose: 'Create an Agentpack checkpoint.' It uses a specific verb and resource. However, it does not distinguish this tool from sibling tools like 'resume' or 'replay' that might relate to checkpoints, missing a chance to clarify uniqueness.

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?

No guidance is provided on when to use this tool versus alternatives. The description does not mention any conditions, required context, or scenarios where 'checkpoint' is preferred.

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