undo_apply

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

Discloses risk level (medium), the mechanism of dispatching an inverse tool through its own governed tool, the one-time nature of token usage, and the dry_run preview behavior. Comprehensive for a write operation with no annotations.

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?

Concise and well-structured: a header with risk tag, a paragraph on behavior, then a list of parameters. Every sentence adds value with no redundancy.

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?

Covers purpose, parameters, risk, constraints, and preview mode. Adequate for a meta-tool with no output schema; only minor missing details like error handling, but overall complete.

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?

Despite 0% schema coverage, the description adds an 'Args' section explaining each parameter's meaning and source (e.g., undo_id from undo_list). Fully compensates for missing schema descriptions.

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 'Apply a recorded undo by dispatching its inverse tool' with a specific verb and resource. It distinguishes from siblings like undo_list by focusing on application rather than listing.

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 explicit guidance: undo_id should come from undo_list, dry_run to preview without executing, token can be applied once. Implies when and how to use the tool.

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