canair

Working with WiCAN OBD-II, Ioniq CAN bus, PID decoding, vehicle profiles, CAN request CLI tool, UDS protocol, expression evaluator. Load this skill when working on the Ioniq reverse engineering project, CAN bus analysis, or WiCAN device configuration.

Guidelines for agents making code or architecture changes to the canair codebase (CLI subcommands, transports, modes, library code, tests). Load this whenever you are adding, refactoring, or removing canair Python code — NOT for reverse-engineering PIDs or editing vehicle data (use the ioniq-reverse-engineering / reverse-engineer-signal skills for that).

Generic, vehicle-agnostic reverse-engineering workflow for canair — the whole flow from orient/discover through capture, analyze, define, verify, integrate, for ANY signal (a PID/DID parameter, a raw broadcast frame field, a routine, an IOControl actuator) on ANY car. Covers WiCAN Bnn / ISO-TP / PCI byte indexing, expression syntax, the analysis reasoning (signal types, physics/EE, statistics), and writing/validating definitions. Use when discovering, decoding, or verifying anything on a vehicle bus, writing or fixing an expression, working out a byte offset, or working a research: backlog — on the bundled Ioniq profile or a profile you built for another car. Examples use the Ioniq for concreteness; the method is generic.
