execute_in_transaction

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

With no annotations, the description must carry the full burden of behavioral disclosure, but it only says the query runs inside an active transaction. It does not explain whether the query can mutate data, whether it leaves the transaction open, what happens on failure, or how it interacts with commit/rollback.

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, front-loaded sentence with no filler or redundant wording. Every word earns its place and the structure is maximally concise.

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?

This tool sits inside a transaction workflow with siblings begin_transaction, commit_transaction, and rollback_transaction, but the description does not explain how the query affects transaction state, whether multiple queries are allowed, or what the expected return behavior is. Without an output schema or annotations, the description is too sparse for reliable use.

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 input schema already describes both parameters with 100% coverage: transactionId is identified as the ID from begin_transaction and query is described as the SQL query. The description adds no additional parameter meaning beyond the schema, so the baseline of 3 applies.

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 verb 'execute' and resource 'a query within an active transaction', which distinguishes it from sibling tools like execute_query by scoping execution to an open transaction. This is specific and immediately understandable.

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 phrase 'within an active transaction' implies the tool should be used after begin_transaction and before commit/rollback, but it does not explicitly name alternatives, exclude outside-transaction queries, or mention when not to use it. Usage context is implied rather than made explicit.

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