Commit Transaction

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

Even with readOnlyHint=false and destructiveHint=false, the description adds meaningful state semantics: it ends the COM undo mark, retains undoability via drawing_undo, and discards the ezdxf rollback snapshot. This clarifies what 'permanent' means and prevents the agent from assuming the changes become un-undoable. No contradiction with annotations.

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 short, front-loaded with the core operation, and each engine-specific line adds a distinct fact about behavior. There is no filler or repetition of schema or annotation data.

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 zero-parameter commit operation, the description covers the important behavior and an output schema exists to describe the return value. The only gap is that it does not state the precondition that a transaction must already be active, or the behavior if none is. This is minor but enough to keep it below a 5.

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 has zero parameters and the schema coverage is 100%, so there is nothing for the description to add beyond what the schema already conveys. Baseline 4 applies for a no-parameter tool.

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 opening sentence names the operation and its object explicitly ('Commit the current transaction'), so an agent knows this finalizes an in-progress transaction. The engine-specific notes clarify what commit means in each backend, and the name distinguishes it from transaction_begin and transaction_rollback, though no sibling is named directly.

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 this tool is used when a transaction is active and changes should be kept, but it never explicitly says 'use this instead of transaction_rollback' or what happens if no transaction is open. A capable agent can infer it from the COM/ezdxf effects, but the guidance is not explicit.

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