rollback_transaction

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'restore' without mentioning that this likely discards current changes, requires an active transaction, or that expected_sha256 is used for integrity verification. The destructive nature is inferred but not stated.

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, short sentence that is front-loaded and contains no fluff. It is concise, but it sacrifices necessary detail for brevity, making it only slightly above average in structure.

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?

The tool is part of a clear transaction management lifecycle, yet the description does not explain how rollback fits into that flow, nor does it clarify the role of expected_sha256. Even with an output schema present, the absence of parameter semantics and usage guidance leaves the tool's complete behavior under-specified.

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?

Schema description coverage is 0%, and the description does not compensate at all. It neither explains the meaning of 'txid' nor the purpose of 'expected_sha256'. The schema provides only parameter names, leaving the agent to guess the exact usage, especially for the optional hash parameter.

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 uses a specific verb 'Restore' with a clear resource 'transaction snapshot or backup', which distinguishes it from sibling transaction tools like commit, begin, and list. However, it is slightly ambiguous about what constitutes a snapshot/backup in the transaction context.

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 gives no guidance on when to use this tool versus alternatives such as preview_transaction, validate_transaction, or abandon_live_session. The transaction lifecycle context is implied by the tool name, but no explicit conditions or prerequisites are stated.

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