rollback_transaction

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

No annotations are provided, so the description carries the full disclosure burden. It does communicate the core effect (discard changes, restore scene state) and a precondition (a matching begin_transaction must exist). However, it says nothing about error behavior when no such transaction exists, nesting, reversibility, or permission requirements.

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?

A single sentence with no filler, front-loading the action and scope. Every clause 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, annotation-free transactional tool with no output schema, the description covers what it does and the precondition for using it. It would be stronger with a note on failure modes or how it differs from undo/redo, but it is largely sufficient.

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 takes zero parameters, so there is no per-parameter meaning to add. Baseline 4 applies: the schema is empty and fully covered, and no parameter documentation is needed.

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?

States a specific verb ('discard') and resource ('changes since the matching begin_transaction') plus the resulting effect ('restore scene state'). The pairing with begin_transaction implicitly separates it from commit_transaction and undo, but no sibling is named explicitly, so it falls short of a full 5.

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 mention of a 'matching begin_transaction' implies the context in which it is valid, but there is no explicit when-to-use guidance, no statement of when-not to use it, and no routing to alternatives like undo or commit_transaction. Usage is only implied.

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