transaction.commit

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

The description adds no behavioral detail beyond the annotations. It does not mention side effects, whether the transaction is persisted, whether rollback is still possible, or any guardedness semantics behind 'Guarded Harness'. Annotations cover some flags but not the actual commit behavior.

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 but not valuable; it is under-specified rather than appropriately concise. 'Guarded Harness lifecycle operation' adds jargon without explanation, and the sentence does not earn its place by conveying actionable information.

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 is a lifecycle-mutating tool with output schema present, but the description still omits critical context: what commit does, whether it is destructive, and how it relates to begin/rollback. An agent calling this without additional knowledge would not understand the operation's consequences.

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 parameters are fully documented in structured form. The description itself adds no parameter meaning, so the baseline score of 3 is appropriate.

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 'Guarded Harness lifecycle operation `transaction.commit`' essentially restates the tool's name/title with no concrete verb or resource. It does not explain that this tool commits/finalizes a transaction, so an agent cannot infer its actual role among sibling transaction tools.

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?

There is no guidance on when to use this tool versus blender_transaction_begin or blender_transaction_rollback. The description gives no prerequisites, ordering hints, or conditions for when a commit is appropriate.

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