longpress

Hold any UI element using a snapshot ref, selector, or screen coordinates to open context menus or trigger hold gestures. Customize press duration to match app-specific requirements.

Instructions

Hold a UI target by snapshot ref, selector, or coordinates to open a context menu or perform another hold gesture. Set durationMs when the default hold duration is unsuitable. Times out after 210s; a caller-supplied budget extends it.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
rawNoUse raw snapshot data during selector resolution.
udidNoiOS device UDID selector.
debugNoEnable debug diagnostics.
depthNoSnapshot traversal depth.
runIdNoLease run identifier.
scopeNoSnapshot scope selector used before resolution.
deviceNoDevice name selector.
serialNoAndroid device or Vega VVD serial selector.
settleNoAfter the action, wait for the UI to go quiet and return the settled diff vs the pre-action tree in the same response. Best-effort; never fails the action.
targetYesUI target. This is separate from deviceTarget, which selects the device form.
tenantNoRemote tenant identifier.
leaseIdNoExisting lease identifier.
sessionNoAgent-device session name.
noRecordNoDo not record this action.
platformNoPlatform selector used to resolve a device.
timeoutMsNoSettle: wait deadline in milliseconds (default 10000).
durationMsNoLong press duration in milliseconds.
includeCostNoInclude per-command agent-cost (cost.wallClockMs, …) in structuredContent. Defaults to off; the default response shape is unchanged.
deviceTargetNoDevice target form. Maps to the CLI --target flag.
responseLevelNoResponse verbosity: token-cheap digest / default (today) / full. Defaults to default; the default response shape is unchanged.
settleQuietMsNoSettle: quiet window in milliseconds (default 500).
mcpOutputFormatNoMCP text content format. Defaults to optimized agent-friendly text; use json for JSON text. Structured content is always returned separately.
androidDeviceAllowlistNoAndroid serial allowlist used for device resolution.

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
xNoResolved interaction x coordinate when available.
yNoResolved interaction y coordinate when available.
refNoSnapshot ref without the @ prefix when the target was an @ref.
costNo
hintNo
settleNo
gestureNo
messageNo
warningNo
evidenceNo
refLabelNo
selectorNoSelector expression when the target was a selector.
durationMsNo
resolutionNoPre-action disclosure of how the acting path resolved its target. Absent when resolutionDisclosure is inapplicable for the path.
targetKindYesResolved interaction target kind.
selectorChainNo
referenceWidthNoReference frame width for visualizing the interaction point.
targetHittableNo
referenceHeightNoReference frame height for visualizing the interaction point.
maestroFallbackReasonNo
maestroNonHittableCoordinateFallbackUsedNoWhether the direct iOS Maestro coordinate fallback was actually used.
maestroNonHittableCoordinateFallbackAllowedNoWhether the direct iOS Maestro coordinate fallback was allowed for this selector.

TDQS

A4.4/5.0
Behavior4/5

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

With no annotations provided, the description carries the behavioral burden. It discloses the 210s timeout, the existence of a caller-supplied budget to extend it, and the default hold duration behavior around durationMs—all beyond what the schema states. It does not detail failure modes or side effects, but the output schema helps cover response shape.

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

Conciseness5/5

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

Three short sentences, front-loaded with the action and resource, then purpose, optional override, and timeout. Every sentence earns its place with no redundancy.

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

Completeness4/5

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

For a tool with 23 parameters and no annotations, the description covers the most critical aspects: what the tool does, how to specify the target, the duration override, and the timeout behavior. The extensive schema and output schema document the remaining parameters and return shape, making this adequately complete without being verbose.

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

Parameters4/5

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 genuine meaning by clarifying that durationMs overrides an unsuitable default, and by summarizing the three target variants (ref, selector, coordinates) in plain language. This goes beyond the schema's raw descriptions.

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

Purpose5/5

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

The description opens with the specific verb 'Hold' and identifies the resource (a UI target) along with the three accepted target forms: snapshot ref, selector, and coordinates. It also states the intended outcome ('open a context menu or perform another hold gesture'), which clearly separates it from sibling tools like click or press.

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

Usage Guidelines4/5

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

The description gives clear usage context by stating the purpose (context menu or hold gesture) and offers a conditional parameter guidance ('Set durationMs when the default hold duration is unsuitable'). It does not explicitly name alternatives or when-not-to-use, so it stops short of a 5, but the context is clear enough for an agent to select it.

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