Apply batch transaction update

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

With no annotations, the description carries the full burden. It adds a useful behavioral note: 'Every target revision is checked again before writing.' This discloses a safety check, but it doesn't mention side effects, permission requirements, idempotency, or error handling. The description adds some value but leaves significant behavioral aspects unaddressed.

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 two short, focused sentences. The first states the purpose, the second adds a behavioral detail. There is no filler or redundant information, making it highly concise and well-structured.

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 tool with one parameter and no output schema, the description is minimally viable. It explains the core action and a safety check, but lacks information about the expected response, the source of the confirmation token, and the relationship to preview_transaction_batch. This leaves gaps for an agent trying to use the tool correctly in a composite workflow.

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 0%, so the description must compensate for the lone parameter 'confirmation_token'. The description says 'previously previewed', which hints that the token comes from a preview, but it doesn't explicitly say to use the token returned by preview_transaction_batch or explain its role beyond being a confirmation. This added meaning is minimal and insufficient.

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 the tool's function: 'Apply a previously previewed batch operation.' The verb 'apply' is distinct from 'preview' in the sibling tool preview_transaction_batch, and the resource is the batch operation. This makes the purpose unambiguous and differentiated from siblings.

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 implicitly tells when to use the tool: after a batch operation has been previewed. This sets a clear prerequisite without explicitly naming alternatives. It doesn't state when not to use it or compare to individual transaction tools like patch_transaction, but the context is sufficient for a simple confirmation step.

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