Warning

Experimental. Ennio is at an early experimental stage. APIs, package
names, internals, and behavior may change without notice between releases.
iOS is the primary target; Android is newer (opt-in via --android) —
its full example suite runs green and stable on CI, but it has seen less
real-world use. The 0.0.x line is a public preview, not a stability commitment.

The biggest release so far: ennio grows an Android backend, an MCP server so AI agents can drive a device through the same pipeline as test flows, an in-house HID layer that drops the last external dependency, and a rewritten CLI. Install is now global-first: npm install -g @reactiive/ennio.

MCP server

  • ennio mcp — serve ennio over the Model Context Protocol (stdio). An agent reads the screen (ennio_describe), decides, and acts (ennio_tap, ennio_swipe, ennio_input_text, …) through the same find → settle → actuate pipeline a test run uses; taps and swipes always go through the HID driver, never a passthrough (#59)
  • Versioned tool contract — structured { ok, data | error } envelopes on every tool, one selector model (testID | text | normalized [0,1] point), capability negotiation via ennio_status, side-effect-honest readOnly flags — all enforced by an executable conformance suite (#59)
  • Tool-agnostic by design: works identically with Claude Code, Cursor, Cline, or a hand-rolled client (#59)

Android backend (opt-in)

  • --android (or ENNIO_PLATFORM=android) — drive an emulator/device over adb with in-process agent injection: deterministic JVMTI attach on debuggable builds, ptrace remote-dlopen on non-debuggable release builds (#52)
  • Focus-identity tracking, regex text matchers, and a network-idle submit gate in the Java agent (#58)
  • Full 40-flow example suite green and stable on CI — three consecutive zero-retry runs; injection rides out emulator soft-lock windows with socket-bind verification and escalating relaunch backoff (#60)

In-house HID

  • idb_companion is gone. Touches are posted by enniohid, an in-house helper that links Xcode's own CoreSimulator / SimulatorKit and posts Indigo HID events directly — same pipeline as a physical finger, one persistent process per run, ~5 ms per event (#46)

New CLI

  • Rewritten command-line experience: animated live view while flows run, global-install-ready, update notice, and crash reports (#56)
  • Flags rationalized: app reuse is now default-on between flows (soft-reset instead of full relaunch — much faster suites); --disable-reuse-app opts out (#54)
  • Fast grey-box profile: --disable-animations + reuse-app + settle tightening (#51)

Reliability

  • iOS keyboard-swallow + autocorrect fixes — the Bluesky e2e suite runs 17/17 (#53)
  • TCC permission grant that sticks, plus a loud warning when cross-process AX is blind
  • Tab recovery asks the app for its tab bar instead of guessing from a name list

Docs

  • READMEs refreshed: global install (npm install -g @reactiive/ennio) instead of a devDependency, MCP section, full CLI command list, corrected injection wording (SIMCTL_CHILD_*, not simulator-wide env), current Android status (#55, #61)
