MySQL Atomic Execute

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

Annotations declare readOnlyHint=false and destructiveHint=false. The description adds atomicity and rollback behavior but omits details like whether a new transaction is started, commit behavior, or effects on existing transactions. More transparency would improve agent decision-making.

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 extremely concise (two sentences) and front-loaded with the core purpose. Every word earns its place with no 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?

Given the complexity of transaction execution and the presence of an output schema, the description is minimal. It does not explain return values, transaction management details, or how this interacts with other transaction tools. An output schema exists but is not provided here, so completeness is moderate.

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 100%, so the baseline is 3. The tool description does not add any extra meaning beyond the schema. The schema itself includes helpful descriptions (e.g., anti-hallucination hint for 'statements'), so the description's contribution is redundant.

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 tool executes multiple SQL statements atomically, with a specific verb ('Execute'), resource ('multiple SQL statements'), and a key semantic ('atomically...all rolled back'). It distinguishes from siblings like mysql_read_query and mysql_write_query by emphasizing atomicity and multiple statements.

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 when atomic execution is needed but does not explicitly state when to use this tool versus alternatives like mysql_transaction_begin + mysql_write_query. The sibling list provides context but the description lacks explicit when/when-not guidance.

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