click_element

Click a UI element by name or automationId using UIA InvokePattern, without screen coordinates. Works for buttons, menu items, and links in native Windows apps.

Instructions

Invoke a UI element by name or automationId via UIA InvokePattern — no screen coordinates needed. The server auto-guards using windowTitle (verifies identity, foreground, modal) and returns post.perception.status. Prefer over mouse_click for buttons, menu items, and links in native Windows apps. Use desktop_discover first to discover automationIds. Pass fixId from a suggestedFix to re-target after window identity drift. lensId is optional for advanced pinned-lens use. Caveats: Typed errors: code:'InvokePatternNotSupported' — the control does not expose InvokePattern, fall back to mouse_click; code:'ElementDisabled' — the element is in a disabled state, re-check preconditions before retry; code:'GuardFailed' — read the perception envelope (attention / guard fields) and choose recovery (re-focus, wait, or pass the suggestedFix.fixId on the next call). Some custom controls do not expose InvokePattern at all; fall back to mouse_click for those.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
hwndNoDirect window handle ID (takes precedence over windowTitle). String to avoid 64-bit precision issues.
nameNoElement name/label (partial match, case-insensitive)
fixIdNoApprove a pending suggestedFix (one-shot, 15s TTL).
lensIdNoOptional perception lens ID. Guards (safe.keyboardTarget, target.identityStable) are evaluated before clicking, and a perception envelope is attached to post.perception on success.
includeNoOptional response-shape opt-in. `['envelope']` returns the self-documenting envelope (`_version` / `data` / `as_of` / `confidence`). `['raw']` forces raw shape (overrides DESKTOP_TOUCH_ENVELOPE=1 server default). Default behaviour is raw shape (compat with existing clients).
narrateNoNarration level. rich includes UIA or browser state diff when supported.minimal
controlTypeNoControl type filter, e.g. 'Button', 'MenuItem'
windowTitleYesPartial window title of the target window. Use '@active' for the current foreground window.
automationIdNoExact AutomationId of the element

Tool Definition Quality

A5/5.0
Behavior5/5

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

No annotations, but description fully covers behavior: auto-guard with windowTitle, returns perception status, lists all typed errors with recovery actions. Mentions custom controls may not support InvokePattern.

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?

Well-structured: main purpose, then usage advice, then caveats and error handling. No unnecessary repetition; every sentence adds value.

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

Completeness5/5

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

Given no output schema, description adequately explains return (perception status, envelope). Covers prerequisites (desktop_discover), error recovery, and optional parameters. Complete for a complex tool with 9 parameters.

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

Parameters5/5

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

Schema coverage 100%, but description adds rich context: explains fixId TTL, lensId guard evaluation, include options, narrate defaults, controlType filter, windowTitle '@active', and hwnd precedence. Goes beyond schema.

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?

Clearly describes invoking a UI element via UIA InvokePattern without coordinates. Distinguishes from mouse_click and browser_click by specifying native Windows apps and fallback conditions.

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

Usage Guidelines5/5

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

Explicitly says prefer over mouse_click for buttons, menu items, links. Advises to use desktop_discover first for automationIds. Provides detailed fallback instructions for errors like InvokePatternNotSupported, ElementDisabled, GuardFailed.

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