rollback_transaction

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

With no annotations provided, the description must disclose behavioral traits on its own. It fails to mention that rollback discards all changes, that the transaction must be active, that it ends the transaction, or any side effects. The description is too minimal to inform the agent of the operational impact.

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, succinct sentence with zero extraneous words. It is front-loaded with the essential verb and object, and is appropriately sized for such a simple tool.

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?

While the tool is simple and has only one parameter, the description does not explain what happens after rollback (e.g., discarding changes, invalidating the transaction), nor does it mention prerequisites like the transaction being active. Without annotations or an output schema, the description carries the full burden of contextual completeness, which it does not fulfill.

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 description covers the sole parameter comprehensively, stating it is 'The transaction ID returned by begin_transaction'. Since schema coverage is 100%, the baseline is 3; the tool description adds no further semantic detail beyond the schema, which is acceptable given the schema's completeness.

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 the action ('Rollback') and the resource ('an active transaction'), leaving no ambiguity about its purpose. It also distinguishes itself from sibling tools like commit_transaction and begin_transaction by indicating it reverses a transaction rather than initiating or finalizing one.

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 does not explicitly state when to use this tool versus alternatives, but the purpose is clear enough that an agent can infer rollback is for aborting a transaction when changes should be discarded. It lacks any mention of exclusions or alternatives, so guidance is implied rather than explicit.

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