raw_undo

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

With no annotations, the description carries the behavioral disclosure burden. It clearly states the action is static, takes no arguments, may open a dialog, and may change project state. This is useful transparency for a state-altering tool, though it does not address what happens when there is no editing action to undo.

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 short and front-loaded: it names the operation, then the no-argument nature, then side-effect warnings. The 'Undo:' prefix slightly duplicates the tool name, but every sentence otherwise earns its place.

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?

For a zero-parameter tool with no output schema, this description is complete. It covers what the action operates on, confirms no arguments are needed, and warns about possible dialogs and project state changes. The inspect-command-name advice adds necessary caution.

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 schema has zero parameters, so the baseline is 4. The description reinforces this by explicitly labeling the action as 'no-argument', which is consistent with the empty input schema and 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 states a specific verb ('undo'), a resource ('the most recent editing action'), and adds that it is a static, no-argument Audacity action. It is clear but does not explicitly distinguish itself from siblings like raw_redo or raw_undo_history.

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 gives a caution ('inspect the command name first') and warns about dialogs or project state changes, but it does not explain when to use raw_undo versus raw_redo or raw_undo_history, nor does it provide exclusions. This is more of a safety note than usable routing guidance.

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