task_checkpoint

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

Annotations indicate idempotency. The description lists what is saved, which is useful, but it does not disclose any other behavioral aspects such as whether existing data is overwritten or merged, or any rate limits.

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?

A single, front-loaded sentence that efficiently states the tool's action and data scope with no extraneous information.

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?

Despite having 9 parameters, the description does not explain the purpose of required parameters ('projectId', 'taskId'), how the checkpoint relates to other task operations, or what the output schema contains. The tool's complexity demands more context.

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%, so the description must compensate. It maps the listed fields (completed, next, changedFiles, etc.) to likely parameter names, but fails to mention the required parameters 'projectId' and 'taskId'. This adds some meaning but is incomplete.

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 uses a specific verb 'Save' and lists the types of data saved (completed work, next steps, etc.), clearly indicating the purpose. However, it does not explicitly distinguish from sibling tools like 'task_complete' which might also involve saving.

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 like 'task_complete', 'task_start', or 'task_list'. The description lacks context on prerequisites or typical sequences.

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