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

With no annotations, the description carries full burden but only mentions parallelism and ordered results. It omits details on error handling, concurrency limits, side effects, or ordering guarantees. Some transparency exists but significant gaps remain.

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 concise sentence covering the core functionality without redundancy. It is appropriately front-loaded, though it could benefit from a brief expansion on ordering or parallelism details without sacrificing conciseness.

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 the tool (multiple task types, no output schema, no annotations), the description is too brief. It fails to explain ordering guarantees, error behavior, return structure, or concurrency limits, leaving the agent with insufficient context for correct invocation.

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 baseline is 3. The description adds no additional meaning beyond the schema for the 'tasks' and 'output_mode' parameters, which are already well-documented in the input schema.

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 'run[s] many tasks in parallel' and returns ordered results, distinguishing it from the sibling 'execute' tool which likely handles single tasks. The verb 'run' and resource 'tasks' are specific and unambiguous.

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 parallel execution of multiple tasks via the phrase 'many tasks in parallel,' which contrasts with the sibling 'execute' tool for single tasks. However, it does not explicitly state when to use this tool over alternatives or provide exclusions.

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