What problem does it solve? It guides engineers through designing, implementing, and validating TritonKit's local CLI control surface for iOS Simulator, Android Emulator, and HarmonyOS / DevEco Emulator, keeping every capability schema-backed, machine-readable, and within the local-only product boundary. ## Core Features & Use Cases - CLI Admission Decisions: Decide whether a capability belongs in the triton CLI, covering target discovery, app lifecycle, observation, actions, evidence, and replay while excluding Web UI, remote agents, real devices, and device clouds. - Schema-Backed Contracts: Keep triton schema, capabilities, doctor, and plan outputs aligned with failure codes, recovery categories, and JSON/JSONL output contracts. - Safety and Evidence Policy: Enforce destructive-action flags, bounded and redacted evidence, ambiguous-target handling, and verification of business postconditions rather than host command success. - Use Case: When adding a new triton device proxy or sim command, use this Skill to route to the right reference file, write failing tests first, update schemas and docs, and validate with focused test runs. ## Quick Start Ask the agent to design and validate a new triton CLI command for iOS Simulator screenshot capture following the emulator takeover workflow.
