batch

Run multiple device commands in a single request to save time and reduce round-trips. Chain steps with structured inputs for efficient automation.

Instructions

Execute multiple commands in one daemon request. Times out after 90s.

Input Schema

TableJSON Schema

Name	Required	Description
`out`	No	Optional output path for command artifacts.
`udid`	No	Apple device or simulator UDID; the selector that pins one device when several share a name.
`debug`	No	Enable debug diagnostics.
`runId`	No	Lease run identifier.
`steps`	Yes	Structured batch steps. Each step uses a command name and the same input object as that command tool.
`device`	No	Device name selector (a UDID belongs in udid, a serial in serial).
`serial`	No	Android, HarmonyOS, or Vega VVD serial selector.
`target`	No	Alias for deviceTarget on commands without a UI target field. Interaction commands reserve target for the UI element.
`tenant`	No	Remote tenant identifier.
`leaseId`	No	Existing lease identifier.
`onError`	No	Batch failure policy.
`session`	No	Agent-device session name.
`maxSteps`	No	Maximum number of steps accepted for this batch.
`platform`	No	Platform selector used to resolve a device.
`includeCost`	No	Include per-command agent-cost (cost.wallClockMs, …) in structuredContent. Defaults to off; the default response shape is unchanged.
`deviceTarget`	No	Device target form. Maps to the CLI --target flag.
`responseLevel`	No	Response verbosity: token-cheap digest / default (today) / full. Defaults to default; the default response shape is unchanged.
`mcpOutputFormat`	No	MCP text content format. Defaults to optimized agent-friendly text; use json for JSON text. Structured content is always returned separately.
`androidDeviceAllowlist`	No	Android serial allowlist used for device resolution.

C2.3/5.0

Behavior2/5

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

Only discloses a 90s timeout. With no annotations provided, the description carries the full burden of behavioral disclosure. It doesn't mention whether steps run sequentially, what happens on failure, whether output is aggregated, or any error handling behavior. The timeout is useful but insufficient.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely short (two sentences), but this is under-specification rather than conciseness. The only substantive information is the timeout; the rest is generic and doesn't justify its place. A more useful description would explain the steps structure and batching semantics.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity (19 parameters, nested steps object, many command options), the description is severely inadequate. It doesn't explain that each step uses a command name and input matching the corresponding MCP tool schema, the maxSteps limit, or the onError policy. An agent would have to infer all usage details from the schema, which is insufficient for effective invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so all parameters are documented in the schema. The description adds no parameter-specific information beyond what the schema provides. Baseline of 3 is appropriate since the schema handles parameter documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a clear verb ('Execute multiple commands') and resource ('daemon request'), but does not differentiate from the many sibling command tools. It doesn't explain that this is a batch wrapper for individual commands, nor mention the steps array. The purpose is identifiable but lacks specificity to distinguish it from alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus calling individual command tools separately. It doesn't mention performance benefits, batching use cases, or when not to use it. The description provides no context for selection among siblings.

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