batch_add_items

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

With no annotations provided, the description carries full burden but only states it's a batch addition operation. It doesn't disclose behavioral traits such as whether it's idempotent, requires specific permissions, handles errors, or returns any output. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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, efficient sentence that front-loads key information ('Add multiple tasks or projects') without unnecessary words. It earns its place by clarifying the batch nature and target system, making it appropriately sized 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?

Given no annotations and no output schema, the description is incomplete for a mutation tool. It lacks details on behavioral context, error handling, or return values, which are crucial for an agent to use it correctly. The high schema coverage doesn't compensate for these gaps in operational transparency.

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 schema description coverage is 100%, so the schema fully documents the 'items' parameter and its nested properties. The description adds no parameter semantics beyond implying batch processing, which is already covered by the tool name and schema. Baseline 3 is appropriate as the schema does the heavy lifting.

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 action ('Add multiple tasks or projects') and target ('to OmniFocus in a single operation'), making the purpose evident. It distinguishes from single-item tools like 'add_omnifocus_task' and 'add_project' by emphasizing batch capability, though it doesn't explicitly name these 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 implies usage for adding multiple items at once, suggesting it's an alternative to single-item tools. However, it doesn't explicitly state when to use this over siblings like 'add_omnifocus_task' or 'add_project', nor does it mention prerequisites or exclusions, leaving guidance incomplete.

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