Batch Operations

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

Annotations already indicate readOnlyHint=false and destructiveHint=true. The description adds that results are returned as a combined array and operations execute in sequence. However, it lacks details on error handling (e.g., atomicity, rollback), which is important for a destructive batch 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 three sentences with no fluff: states purpose, explains structure, and gives usage guidance. Well-structured and front-loaded.

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 batch tool's complexity and destructive hint, the description covers basics (purpose, usage, structure) but omits critical context like failure behavior, result format per operation, and prerequisites. Leaves gaps for a high-stakes tool.

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 coverage is 100%, so the description adds no new parameter details beyond the schema. It mentions 'each operation specifies a tool name and its arguments,' which is redundant with the schema's 'ordered list of {tool, args} operations to execute.' Baseline 3 applies.

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 'Executes multiple tool operations in sequence within a single call,' with a specific verb and resource. It distinguishes itself from sibling tools (individual operations) by being a batch wrapper.

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 explicitly advises 'Use this to chain several steps without round-trips,' providing clear context for when to use the batch tool. It implies alternatives are individual calls, though it doesn't list exclusions.

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