Save KiCad Checkpoint

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

With no annotations, the description carries the full burden of behavioral disclosure, but only states 'Save an exact checkpoint'. It does not explain overwrite behavior, naming conventions, or failure modes, leaving significant behavioral ambiguity for a mutating operation.

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 concise at two short sentences and front-loaded with the core purpose. The second sentence referencing SKILL.md is a minor addition but does not bloat the description.

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 the absence of annotations and output schema, the description is too sparse. It omits critical context about how checkpoints are stored, how this tool relates to restore_checkpoint/list_checkpoints, and any side effects, making it incomplete for a tool in a 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?

The input schema already provides descriptions for both parameters (path and description), so the baseline is 3. The description adds no additional parameter semantics beyond implying 'one KiCad file' maps to the path parameter.

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 a specific resource 'exact checkpoint of one KiCad file', clearly distinguishing it from sibling tools like list_checkpoints and restore_checkpoint. This is a clear, unambiguous statement of the tool's purpose.

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 provides no guidance on when to use this tool versus alternatives, nor does it mention prerequisites or typical workflows. The 'Agent instructions' reference is not a substitute for in-description usage context.

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