undo.revert

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

With no annotations present, the description carries the full burden of behavioral disclosure. It only states 'Revert undo transaction' without explaining side effects, changes to session state, required permissions, or whether the action is reversible. The agent is left completely uninformed about what happens when this tool is invoked.

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 under-specified, not concise. A single phrase is insufficient for a tool in a complex undo/redo system. Essential information is missing, so brevity here is a drawback, not a virtue.

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 of the tool (part of an undo system with many siblings) and the absence of any supplementary information (no output schema, no parameter descriptions, no annotations), the description is severely incomplete. The agent cannot safely or correctly use this tool based solely on the provided definition.

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 two parameters (session_id, transaction_id) with no descriptions (0% coverage). The description does not mention either parameter, so it adds no meaning or guidance on how to use them. The agent cannot infer what values to provide or their significance.

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 'Revert undo transaction' is vague and ambiguous. It does not clearly specify what action is performed (e.g., cancel an undo operation, redo an undone action) and does not distinguish from sibling tools like undo.undo or undo.redo. The verb 'revert' is not standard in undo/redo contexts, causing confusion.

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 guidelines are provided about when to use this tool versus alternatives. There is no mention of prerequisites, such as having an active undo transaction, or when revert is preferred over undo.undo or undo.redo. The agent has no basis to choose this tool correctly.

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