Annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=true and openWorldHint=true, so the safety profile is covered. The description adds the useful scoping fact that the transaction binds to the active session, but omits what happens on error, whether autocommit is suspended, and behavior when a transaction is already open.
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?
A single front-loaded sentence with zero filler; the verb and scope appear immediately. Nothing in the sentence is redundant with the title or annotations.
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?
An output schema exists, so return values need not be explained, and annotations carry the safety profile. What is missing is transactional lifecycle context (pairing with commit/rollback, session scoping implications, nesting/error behavior) that an agent needs to use this correctly in a sequence of DML calls.
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 there is nothing for the description to disambiguate; the baseline for a parameterless tool is 4. Schema coverage is nominally 100% and the empty schema matches the description's lack of arguments.
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?
States a specific verb (begin) and resource (an explicit transaction) scoped to the active session, which is unambiguous. It does not, however, name its natural lifecycle partners snowflake_commit_transaction / snowflake_rollback_transaction, so the transactional grouping must be inferred from sibling names.
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?
Usage is only implied: an agent can guess this precedes a multi-statement unit of work, but the description never says when to start a transaction versus issuing individual statements, nor that it must be closed with commit or rollback. No 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.
