begin_transaction

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

With no annotations, the description carries the burden of behavioral disclosure. It usefully states that the transaction is nested and must be paired with commit or rollback, but it does not explain transaction scope, what happens to uncommitted edits, or any limitations on nesting depth.

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 concise sentence with the core action front-loaded and the lifecycle relation immediately following. Every part of the sentence 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 parameterless transaction-control tool with no output schema and no annotations, the description provides the essential lifecycle context: start a nested editing transaction and end it with commit or rollback. It could say more about nested transaction behavior, but it is sufficient for correct invocation.

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 the baseline is 4. The description does not add parameter semantics, but there are no parameters to document.

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 states a specific verb and resource: 'Start a nested editing transaction.' It distinguishes the tool from its transaction-control siblings by explicitly naming the commit_transaction and rollback_transaction counterparts, so an agent can tell what this tool initiates.

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 pairing instruction 'pair with commit_transaction or rollback_transaction' gives clear context for how and when this tool is used. It does not explicitly state when not to use it or how to choose between commit and rollback, but the immediate usage relationship is clear.

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