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

No annotations provided, so description carries full disclosure burden. Explains LIFO stack behavior, restoration of previous state, and specific return value for empty-log condition. Mentions 'checkpoint' concept indicating transaction boundaries. Could enhance by describing success return value or side-effect handling, but adequately covers core behavioral traits.

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?

Three well-structured sentences with zero waste. Front-loaded with scope (operation types), followed by effect (restores state), then usage pattern and error condition. No redundant phrases or schema repetition.

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?

Appropriately complete for a zero-parameter mutation tool without output schema. Documents the undo stack mechanism, eligible operation types, and empty-state response. Mentions checkpoint concept which contextualizes persistence boundaries. Minor gap: doesn't describe success return format, though 'Restores previous state' implies the affected task is returned or modified.

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?

Input schema contains zero parameters (empty object). Per calibration guidelines, 0 params warrants baseline score of 4. Description correctly implies no arguments needed by focusing purely on internal operation log state.

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?

Specific verb ('Undo') + resource ('operation'/'task') with explicit scope listing exactly which operations can be reversed (add, modify, delete, done, start, stop, annotate). Clearly distinguishes from sibling mutation tools by defining itself as the inverse/restoration operation.

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?

Provides clear usage pattern ('Can be called repeatedly to undo multiple operations in reverse order') and boundary condition ('Returns Nothing to undo if the operation log is empty'). Lists compatible operations implicitly guiding when to invoke versus when not to (empty log/checkpoint). Lacks explicit comparison to single alternative tools, though none exist in siblings.

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