bulk_update_transactions

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

With no annotations, the description carries the burden of disclosing behaviors. It mentions 'parallel' execution and the dry_run option, which are useful. However, it does not disclose side effects on partial failures, atomicity, response format, or required permissions, leaving significant behavioral gaps for a bulk mutation tool.

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 sentences, front-loaded with the primary action. Every word contributes value, with no repetition or filler.

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?

The tool has no output schema and a nested parameter structure. The description does not explain return values, error handling, or whether updates are atomic. Given the complexity of a bulk operation, this is a significant omission.

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 provides complete descriptions for both parameters (dry_run and updates) with 100% coverage. The tool description adds no extra parameter meaning beyond what the schema already states, so a baseline 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 clearly identifies the tool's function: updating multiple transactions, with the distinctive 'in parallel' behavior distinguishing it from the single-update sibling tool update_transaction. The verb 'update' and resource 'transactions' are specific.

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 usage for batch updates via 'multiple transactions', but it does not explicitly name the alternative (e.g., update_transaction) or state when NOT to use this tool. There is no exclusion guidance, but the 'parallel' context provides some implied usage.

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