App Tester reads an app's navigation source, adds accessibility identifiers and structured logs, and drives end-to-end flows through agent-device on iOS, macOS, tvOS, or Android. It verifies steps with compact accessibility snapshots and console output, taking screenshots only on failure, and persists the screen graph and flows as YAML. Platform SDKs and Node.js 22+ are still required.

Tell Claude what digital traffic to capture and this skill detects the analyzer, builds the sigrok-cli command, saves a raw session, and decodes protocols such as I2C, SPI, UART, or JTAG offline. It can then summarize NACKs, framing errors, and register values. Claude Code, sigrok-cli with decoder support, and compatible hardware are required; the included device profile currently targets the Sipeed SLogic16 U3.

Explore an application once through Playwright MCP to generate maintainable spec files, then replay them with the Playwright CLI instead of repeating browser-driven reasoning. The toolkit adds accessibility, console, network, and regression checks, fingerprints bugs across runs, and keeps tests and reports in the repository. It does not include managed cloud execution or human triage.

Describe an AWS problem such as recent 500 errors, authentication failures, or crashing ECS tasks. The skill selects relevant logs, builds a CloudWatch query, saves the result, and reports likely causes; it can also show health, alarms, and trends. A setup command discovers log groups, ECS resources, alarms, and the active region. Claude Code and a credentialed AWS CLI are required.
