• electron_assert_patternValidate, in a single check (no polling), that an element's text or a named attribute matches a pattern. Target by ref or selector. With `attribute` set, reads that attribute; otherwise reads the element's trimmed text. Provide exactly one of: equals, contains, matches_regex. Optional flags (any of i, m, s, u) apply to matches_regex; g and y are rejected as stateful. Returns: { ok, session_id, matched, actual }. Errors: EXPECTATION_FAILED (element found but its value did not match the pattern — details carry expected + actual; a missing attribute reads as actual: null), SELECTOR_NO_MATCH (no element matched — this is one-shot, so a missing element is a precondition failure, not a retry; carries similar_refs), REF_NOT_FOUND (stale ref), TRANSPORT_UNSUPPORTED, NOT_RUNNING, BAD_ARGUMENT (no/multiple predicates, invalid regex or flags, or ref+selector both/neither).
• electron_attachAttach to an already-running Electron app exposing a CDP debug endpoint (use electron_discover_running to find one, or start the app with --remote-debugging-port). Provide port (+ optional loopback host) or a loopback cdpUrl; pid alone is not attachable over CDP but, when supplied alongside, lets stop escalate to SIGKILL. The CDP transport supports eval/read/observe and core interaction surfaces against the attached app. The selected CDP page is also the default snapshot/find surface; explicit iframe/webview surface targeting remains unavailable. Returns: { ok, session_id, transport, windows, capabilities }. Errors: TRANSPORT_UNSUPPORTED (no attach-capable transport), CDP_DISCONNECTED (endpoint unreachable or dropped; retryable), CDP_TIMEOUT (handshake/method timeout; retryable), BAD_ARGUMENT (missing target selector or non-loopback endpoint).
• electron_checkCheck the checkbox/radio identified by ref or selector (no-op if already checked). Options: force, timeoutMs. Returns: { ok, session_id, target, checked: true }. Errors: REF_NOT_FOUND / SELECTOR_NO_MATCH (carries similar_refs), ELEMENT_NOT_VISIBLE (retryable), ELEMENT_DISABLED, NOT_RUNNING, BAD_ARGUMENT.
• electron_clear_inputClear the value of the input/textarea identified by ref or selector (sets it to empty). Options: force, timeoutMs. Returns: { ok, session_id, target, cleared }. Errors: REF_NOT_FOUND / SELECTOR_NO_MATCH (carries similar_refs), ELEMENT_NOT_VISIBLE (retryable), ELEMENT_DISABLED, NOT_RUNNING, BAD_ARGUMENT.
• electron_clickClick the element identified by ref (from a snapshot) or selector. Options: button (left|right|middle, default left), clickCount (2 = double-click), force (bypass actionability), timeoutMs. Returns: { ok, session_id, target }. Errors: REF_NOT_FOUND / SELECTOR_NO_MATCH (no such element — re-snapshot; not retryable, carries similar_refs), ELEMENT_NOT_VISIBLE (retryable), ELEMENT_DISABLED (not retryable), NOT_RUNNING, BAD_ARGUMENT (ref+selector both/neither).
• electron_console_logsRead the captured renderer console output for the session, newest-relevant entries last. Filters (all optional, ANDed): type (one or more of log/info/warning/error/debug/...), match (a regular expression the text must match), since (epoch ms — only entries at/after it), limit (max entries, default 200, max 1000 — the most recent are kept). Returns: { ok, session_id, entries: [{ type, text, timestamp, windowId?, location? }], count, overflowed }. overflowed is the number of older entries the buffer dropped. Errors: NOT_RUNNING, BAD_ARGUMENT (invalid regex, or multiple sessions).
• electron_detachDisconnect from an attached or injected app without stopping it. A launch-owned session cannot detach because its transport owns the process; this includes Playwright development launches and packaged CDP launches. Use electron_stop for that case. Returns: { ok, session_id, detached: true }. Errors: TRANSPORT_UNSUPPORTED (launch-owned session; not retryable), NOT_RUNNING (no such session), BAD_ARGUMENT (multiple sessions).
• electron_dialog_handlerArm the auto-responder for native JS dialogs (alert/confirm/prompt/beforeunload) and read which dialogs fired. Dialogs block the renderer, so the policy is applied automatically the instant one appears. Arming args (all optional): action (accept|dismiss — the default for every dialog), perType (per-kind overrides, e.g. {"confirm":"accept","beforeunload":"dismiss"}, falls back to action), promptText (text submitted to prompt() when it is accepted), oneShot (apply to exactly the next dialog, then revert to dismiss). With NO arming args the call is inspect-only and leaves the policy unchanged. Read args (all optional): type (one or more kinds to include), since (epoch ms), limit (max events, default 50, max 200 — most recent kept), clear (flush the whole buffer after reading). Until armed, the default policy is dismiss, so dialogs never hang the app. Returns: { ok, session_id, policy, entries: [{ type, message, action, defaultValue?, promptText?, timestamp, windowId? }], count, overflowed }. overflowed counts dropped events across the whole buffer, not just the returned (type/since/limit-filtered) subset. Errors: NOT_RUNNING, BAD_ARGUMENT (promptText without an accepting prompt policy, or oneShot without a policy to arm).
• electron_discover_runningScan the conventional CDP debug ports (9222-9225 by default) for already-running, debuggable Electron apps on loopback only. No session required. Returns: { ok, targets, count, scanned } where each target is { targetId, port, appName, pid } and scanned reports { host, ports, elapsed_ms } so an empty result is unambiguous. Errors: BAD_ARGUMENT (non-loopback host, invalid port list, or timeout outside bounds). A failed probe is simply "no target on that port".
• electron_doctorRun non-mutating preflight checks without starting an Electron session: Node version, Playwright, Electron, Linux display, configured app root and screenshot directory, eval policy, and project Electron runtime alignment. Returns: { ok, doctor_ok, checks, runtime }, where runtime includes server and, with --app-root, target Electron/Node/V8/ABI facts plus a bounded native-addon inventory. Inspect failed checks and warnings before electron_launch. Errors: none.
• electron_dragDrag the source element (ref or selector) onto the target element (targetRef or targetSelector), using the real mouse API. Options: force, timeoutMs. Returns: { ok, session_id, source, target }. Errors: SELECTOR_NO_MATCH / REF_NOT_FOUND (carries similar_refs), ELEMENT_NOT_VISIBLE (retryable), NOT_RUNNING, BAD_ARGUMENT (a side missing or both ref+selector given).
• electron_drop_fileSimulate dropping OS files onto the element identified by ref or selector. Web DataTransfer mode: reads each path on the host running the server, rebuilds the files in the renderer, and dispatches dragenter/dragover/drop with a real DataTransfer — engaging standard web drop handlers. Paths must be ABSOLUTE (max 10 files, 5242880 bytes each). default_prevented reports whether a drop handler engaged (called preventDefault); false usually means the target has no web drop handler. Apps that resolve dropped files to native OS paths need an app-specific IPC convention this tool does not simulate. Options: mimeType, timeoutMs. Returns: { ok, session_id, target, files, default_prevented }. Errors: ABSOLUTE_PATH_REQUIRED, FILE_NOT_FOUND, BAD_ARGUMENT (too many/large files, or ref+selector both), SELECTOR_NO_MATCH / REF_NOT_FOUND (carries similar_refs), NOT_RUNNING.
