project_undo

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

No annotations exist, and the description provides minimal behavioral disclosure. It does not explain that undo is reversible via redo, whether it affects multiple actions, or if it is destructive. The agent lacks crucial context about the undo stack.

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 (three words), but it sacrifices completeness. A sentence or two more would improve clarity without losing conciseness.

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 complexity (no parameters, no output schema), the description should at least mention that undo can be called repeatedly or that it uses a history stack. It lacks this context, making it incomplete for reliable agent use.

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 description cannot add meaning beyond the schema. Baseline is 4, and the description is minimal but sufficient for a parameterless tool.

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 clearly states it undoes the last action, with a specific verb and resource. However, it does not distinguish from sibling tools like 'project_redo' or clarify the scope of 'last action' (e.g., project-wide vs. track-level).

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 'project_redo' or sequential undo behavior. There is no mention of prerequisites or limitations.

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