✓ TRANSACTION: Commit transaction, making changes permanent. Releases locks.

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

With no annotations, the description carries the full burden. It discloses that the action is permanent and releases locks, but does not mention error conditions (e.g., no active transaction), need for database_name, or return value. Partial transparency.

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 very short and front-loaded with the checkmark and 'TRANSACTION'. It wastes no words, though it repeats the title. Acceptable conciseness.

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 tool's transactional nature and lack of output schema, the description omits important context: it should mention that it must be used after begin_transaction, what happens if no transaction exists, and the purpose of the optional parameter. Feels incomplete.

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 only parameter database_name is optional but not explained anywhere. Schema coverage is 0%, and the description does not clarify its purpose (maybe specifying which database to commit?). The parameter semantics are unclear.

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?

Tautological: description restates name/title.

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 the tool is used after making changes in a transaction, but it does not explicitly state when to use it vs. rollback_transaction, nor mention prerequisites like an active transaction. Usage is implied but not explicit.

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