Read the shared contract. Preserve source locations and existing pinned tooling before proposing migration.
Run the offline inspector: uv run scripts/inspect_build.py --project PATH. It never builds, flashes, opens ports, installs packages or executes project scripts. It returns argument arrays, not shell commands. Treat custom build scripts as code to review before a separately authorized build.
Read toolchain branches for the detected framework. Choose the repository's build manager, not an Arduino default. If PlatformIO contains extra_configs, extends or interpolation, obtain its native computed configuration and retain unresolved status meanwhile. Do not share raw computed config when it contains credentials.
Record board/carrier revision, module suffix, flash and PSRAM separately, environment, host OS, tool versions and dependency resolution. For ESP32-S3 memory work, read memory evidence; use scripts/check_memory_config.py only with the explicit physical profile and provenance of the selected generated sdkconfig.
Build every declared program/environment in scope. If an input program has no build path, report it; do not infer that every sketch needs a sibling INI when a root project already owns its source. Reuse the same matrix in CI.
Keep migration staged: baseline build, bounded API/driver adaptation, host tests, native build, then authorized target tests. Arduino libraries may rely on Wire, timing, callbacks and runtime initialization unavailable natively.
Report the inspected evidence and unverified stages. Use the support matrix, not a family-wide badge.

Outputs

project paths; all declared environments; framework and manager;
explicit versions, unresolved inheritance and custom-script trust boundary;
build/test argument arrays and actual results, when execution was authorized;
four memory outcomes: confirmed-mismatch, consistent-with-inspected-evidence, unresolved, not-applicable;
source revision/input hashes, selected environment and artifact identity;
upload, physical memory population and runtime behavior marked unverified.

Ownership

The workflow router retains combined board/wiring/application work. arduino-cli-skill owns Arduino CLI commands; native projects stay here. board-support resolves board identity; this skill checks build configuration. realtime-control-design, freertos-patterns and wireless-telemetry own their respective designs. Keep pin and electrical claims outside the inspector.

Sources and verification

The helpers use the Python standard library. Run uv run -m unittest discover -s tests -p test_embedded_workflows.py from the package root. See source lessons and research lineage. Tests of the helper prove its output and uncertainty handling, not a firmware build. Run the trusted compile fixtures separately before claiming build proof.

Platform procedures

Use the selected specialist for concrete native mechanics: Zephyr, STM32Cube, Pico SDK, MicroPython. Rust is outside the current implementation scope.
