The harness is dev-only tooling for AI agents and integration tests. It should not ship to end users who install the CLI. - Gate MCP harness esbuild behind BUILD_HARNESS=1 env var - Remove agent-tui-harness bin entry from package.json - Add !dist/mcp-harness to files array (npm publish exclusion) - Remove node-pty from optionalDependencies (stays in devDependencies) - Add build:harness script, update test:tui to use it - Update AGENTS.md to reference npm run build:harness Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
27 tests across 5 suites verifying the TUI harness against the real AgentCore CLI: harness self-tests, navigation flows, create wizard, add-resource flows, and deploy screen rendering. Tests use describe.skipIf(!isAvailable) to gracefully skip when node-pty is not installed. createMinimalProjectDir provides fast (~10ms) project directory setup without npm install.

Description
Adds 27 integration tests across 5 test suites that exercise the TUI harness against the real AgentCore CLI binary. These tests validate that AI agents can reliably drive the TUI through all major user flows.
Test suites:
harness.test.ts(9 tests) — Self-tests forTuiSessionusing simple Unix commands (echo,cat,bash). Validates launch, sendKeys, close, dead-session errors, waitFor success/timeout, LaunchError, concurrent sessions, and numbered readScreen.navigation.test.ts(8 tests) — TUI navigation against the real CLI. HomeScreen rendering, HelpScreen rendering, forward/backward navigation, exit via double-Escape and Ctrl+C.create-flow.test.ts(3 tests) — Full create-project wizard: create with agent (20+ step wizard), create without agent, and back-navigation during wizard.add-flow.test.ts(4 tests) — Add-resource flow: navigate to Add Resource screen, drill into Add Agent wizard, and escape-back at each level.deploy-screen.test.ts(3 tests) — Deploy screen: renders, shows AWS configuration, supports Escape-back. Never actually deploys.Infrastructure:
