v0.0.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
There are no annotations, so the description must carry the full burden of behavioral disclosure. It only says 'redo the last operation,' without explaining side effects, reversibility, state mutation, or error behavior when no operation is available.
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 with no unnecessary words, front-loading the action. However, the brevity borders on under-specification, though not to the point of being a tautology.
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 no annotations or output schema, the description is far from complete. It doesn't clarify 'selected model' or 'last operation,' nor does it mention any success/failure conditions or relationship to sibling tools like 'undo' or snapshots.
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, so the schema already covers everything (100% coverage vacuously). The description adds no parameter details, which is acceptable per the baseline 4 for 0-parameter tools.
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 'redo the last operation on the selected model,' which clearly identifies the action (redo) and the target (last operation on the selected model). It is distinct from sibling 'undo' by inversion, but doesn't explicitly name any sibling or alternative.
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 about when to use this tool versus alternatives like 'undo' or 'restore_snapshot.' The description lacks any mention of prerequisites, such as a prior undo, or the context of the selected model.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
