rollback_model_transaction

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

With no annotations, the description carries the full burden. It discloses the destructive effect (discards all accumulated changes) and notes the engine never sees them, referencing the underlying API. This adds meaningful transparency, though it does not mention potential side effects or error conditions.

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 a single, well-structured sentence that front-loads the key action and provides necessary context without any redundant filler.

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 simple tool, the description covers the main behavior clearly. However, it omits prerequisites such as requiring an open transaction (via begin_model_transaction) and does not clarify what happens if sessionId is invalid or no transaction is open.

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 one parameter (sessionId) with 0% description coverage. The description does not mention sessionId at all, leaving its role and format unexplained. Since there is only one parameter, a brief mention would be expected to compensate.

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 a specific verb and resource: 'Roll back the open model transaction', and further explains it discards every accumulated TOM change. This distinguishes it from sibling tools like commit_model_transaction, which would apply changes.

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 implies usage context: when you want to discard changes to the model rather than commit them. However, it does not explicitly name alternative tools or provide when-not-to-use conditions, though the contrast with commit_model_transaction is clear.

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