transaction

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

With no annotations, the description must compensate. It mentions atomicity, implying rollback on failure (supported by the rollbackOnError parameter), but doesn't elaborate on order, concurrency, or error behavior beyond the schema.

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 sentence that effectively conveys the core purpose. No wasted words, and it is front-loaded with the key concept 'atomic transaction'.

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 complexity of bundling file operations and the lack of an output schema, the description fails to explain the return value, error handling, or how the atomicity is guaranteed. It is too brief for a tool that groups multiple actions.

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 has 100% description coverage, so the schema already explains each parameter clearly. The description adds no additional semantic value for the parameters.

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 it executes file operations atomically, distinguishing it from single-file tools. However, it doesn't differentiate from sibling tool 'batch_operations', which also handles multiple operations but may not be atomic.

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 provides no guidance on when to use this tool vs alternatives like batch_operations or individual file tools. It also omits prerequisites or conditions for atomicity.

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