-# hil
-
-Run Hardware-in-the-Loop (HIL) tests on physical boards.
-
-## Arguments
-- $ARGUMENTS: Optional flags (e.g. board name, extra args). If empty, runs all boards with default config.
-
-## Instructions
-
-1. Parse $ARGUMENTS:
- - If $ARGUMENTS contains `-b BOARD_NAME`, run for that specific board only.
- - If $ARGUMENTS is empty or has no `-b`, run for all boards in the config.
- - Pass through any other flags (e.g. `-v` for verbose, `-r N` for retry count) directly to the command.
-
-2. Determine whether to run **locally** or **remotely via SSH**:
- - **Local**: boards are attached to this machine (default when `local.json` is used)
- - **Remote (`ssh ci.lan`)**: boards are attached to the CI machine (when `tinyusb.json` is used)
-
-3. **Local execution** (boards attached to this machine):
- ```bash
- python test/hil/hil_test.py -b BOARD_NAME -B examples $HIL_CONFIG $EXTRA_ARGS
- ```
-
-4. **Remote execution** (boards attached to `ci.lan`):
- Only copy the minimal files needed (firmware binaries + test script + config), then run remotely.
-
- ```bash
- REMOTE=ci.lan
- REMOTE_DIR=/tmp/tinyusb-hil
-
- # Create remote working directory
- ssh $REMOTE "rm -rf $REMOTE_DIR && mkdir -p $REMOTE_DIR/test/hil"
-
- # Copy HIL test script and its dependency
- scp test/hil/hil_test.py test/hil/pymtp.py test/hil/tinyusb.json $REMOTE:$REMOTE_DIR/test/hil/
-
- # Copy only the firmware binaries for the target board(s)
- # For a specific board:
- scp -r examples/cmake-build-$BOARD_NAME $REMOTE:$REMOTE_DIR/examples/
-
- # Or for all boards that have been built:
- # for dir in examples/cmake-build-*/; do scp -r "$dir" $REMOTE:$REMOTE_DIR/examples/; done
-
- # Run the test remotely
- ssh $REMOTE "cd $REMOTE_DIR && python3 test/hil/hil_test.py -b $BOARD_NAME -B examples tinyusb.json $EXTRA_ARGS"
- ```
-
- Note: The remote machine (`ci.lan`) must have:
- - Python 3 with `pyserial` installed (`pip install pyserial`)
- - Flasher tools: `JLinkExe`, `openocd`, etc. as needed by the board
- - USB access to the boards (udev rules configured)
-
-5. Use a timeout of at least 20 minutes (600000ms). HIL tests take 2-5 minutes. NEVER cancel early.
-
-6. After the test completes:
- - Show the test output to the user.
- - Summarize pass/fail results per board.
- - If there are failures, suggest re-running with `-v` flag for verbose output to help debug.

+name: code-size
+description: Use when comparing TinyUSB code size between a base ref (master by default) and the current branch to evaluate the size impact of changes. Three granularities — single example on one board (with optional bloaty), all examples on one board, or all examples across CI families combined.
+---
+
+# Code Size Comparison
+
+Compare TinyUSB code size between a base ref (default `master`) and the current branch using `tools/metrics_compare_base.py`. Three granularities — pick the narrowest one that exercises your change:
+
+| Granularity | When to use | Command |
+|---|---|---|
+| **single example, one board** | Focused change touching one feature | `-b BOARD -e device/cdc_msc` |
+| **all examples, one board** | Per-board regression sweep | `-b BOARD` |
+| **all examples, all CI families (combined)** | Pre-merge full check | `--ci` |
+
+The script handles the full base-vs-branch dance:
+1. Creates a temporary git worktree of the base ref under `cmake-metrics/_worktree/`.
+2. Builds the base in `cmake-metrics/<board>/base/`.
+3. Builds the current tree in `cmake-metrics/<board>/build/`.
+4. Runs `tools/metrics.py compare` and writes `cmake-metrics/<board>/metrics_compare.md`.
+5. Removes the worktree on exit.
+
+`--combined` (auto-set by `--ci`) also produces `cmake-metrics/_combined/metrics_compare.md` aggregating across all boards.
+
+## Choosing arguments
+
+Infer from the user's request:
+
+- **Board(s):** named board → `-b BOARD` (repeatable). "All boards" / "CI" / "full sweep" → `--ci` (first board of each arm-gcc family). Default to a fast board (`raspberry_pi_pico`) if unspecified for an iterative check.
+- **Example:** named example → `-e <group>/<name>` (e.g. `-e device/cdc_msc`). "All examples" → omit `-e`.
+- **Bloaty:** only with `-e`. Use when the user wants a section/symbol-level breakdown for a single binary.
+- **Base ref:** default `master`. Override with `--base-branch <ref>` (tag or commit also works).
+- **Filter:** default is the absolute path of each side's `<checkout>/src/` directory, which uniquely identifies TinyUSB stack code without matching vendored deps that also have a `src/` (e.g. `pico-sdk/src/`). Override with one or more `-f SUBSTRING` flags to use repo-relative substrings instead. Change only if asked.
+
+## Common invocations
+
+```bash
+# Single example, one board (linkermap, fastest):
+python3 tools/metrics_compare_base.py -b raspberry_pi_pico -e device/cdc_msc
+
+# Same with bloaty for section/symbol breakdown:
+python3 tools/metrics_compare_base.py -b raspberry_pi_pico -e device/cdc_msc --bloaty
+
+# All examples for one board:
+python3 tools/metrics_compare_base.py -b raspberry_pi_pico
+
+# Multiple boards, one combined report:
+python3 tools/metrics_compare_base.py -b raspberry_pi_pico -b raspberry_pi_pico2 --combined
+
+# Full CI sweep (first board per arm-gcc family, combined):
+python3 tools/metrics_compare_base.py --ci
+
+# Compare against a tag/commit instead of master:
+python3 tools/metrics_compare_base.py -b raspberry_pi_pico --base-branch v0.18.0
+```
+
+## Outputs
+
+- **Per-board:** `cmake-metrics/<board>/metrics_compare.md` (and `_<example>.md` when `-e` is set)
+- **Combined (with `--combined`/`--ci`):** `cmake-metrics/_combined/metrics_compare.md`
+- **Bloaty:** printed to stdout as section + symbol diffs
+
+## Timing
+
+- Single example, single board: ~30 s
+- All examples, single board: ~60-90 s
+- `--ci` (all arm-gcc families, first board each): 4-8 minutes — sequential sweep across boards (Ninja parallelizes within each board, not across)
+
+Use timeouts ≥ 10 minutes (600000 ms) for `--ci`.
+
+## Reporting results
+
+After running:
+- Show the markdown report's summary table to the user.
+- Highlight any rows with non-zero `% diff` — under the default filter every row is a TinyUSB stack source file (e.g. `usbd.c`, `cdc_device.c`, `dcd_<port>.c`), so any non-zero delta is a real stack-size impact.
+- If the diff is unexpected, follow up with a single-example `--bloaty` run to localize.

+name: hil
+description: Use when running TinyUSB Hardware-in-the-Loop (HIL) tests on physical boards, debugging HIL failures, or copying firmware to the ci.lan test rig. Covers local execution and remote execution over SSH, config selection, and debugging tips.
+---
+
+# Hardware-in-the-Loop (HIL) Testing
+
+Run TinyUSB HIL tests against real boards. Two execution modes — **local** (boards attached to this machine) and **remote** (boards attached to `ci.lan`, reached over SSH). Default to **local** unless the user specifies `remote`. Do not auto-detect.
+
+## Prerequisites
+
+- Examples must already be built for the target board(s). See AGENTS.md "Build" → "All examples for a board", which produces `examples/cmake-build-<board>/`.
+- `-B examples` tells `hil_test.py` that `examples/` is the parent folder containing the per-board build outputs.
+
+## Choosing arguments
+
+Infer from the user's request:
+
+- **Mode:** `local` (default) or `remote`. Only switch to `remote` if the user explicitly says so or names `ci.lan`.
+- **Board:** if the user names a specific board, pass `-b BOARD_NAME`. Otherwise omit `-b` to run all boards in the config.
+- **Pass-through flags:** `-v` (verbose), `-r N` (retry count), etc. — pass through unchanged.
+
+Config file follows from mode:
+- **Local** → `test/hil/local.json` (user-supplied; not tracked in repo — describes boards attached locally)
+- **Remote** → `test/hil/tinyusb.json` (tracked; describes the `ci.lan` test rig)
+
+If `local.json` is missing, fall back to `tinyusb.json` only when explicitly told to; otherwise stop and ask the user to supply one.
+
+## Local execution
+
+Boards attached to this machine:
+
+```bash
+# Specific board:
+python3 test/hil/hil_test.py -b BOARD_NAME -B examples test/hil/local.json $EXTRA_ARGS
+# All boards in the config (no -b):
+python3 test/hil/hil_test.py -B examples test/hil/local.json $EXTRA_ARGS
+```
+
+## Remote execution (ci.lan)
+
+Use `test/hil/hil_ci.sh` — it handles dir setup, scp of test scripts, rsync of firmware artifacts (`.elf` / `.bin` / `.hex` only), and running `hil_test.py` on `ci.lan`:
+
+```bash
+# Specific board:
+bash test/hil/hil_ci.sh -b raspberry_pi_pico2
+# All boards in tinyusb.json:
+bash test/hil/hil_ci.sh
+# Pass-through extra args (any non -b flag is forwarded to hil_test.py):
+bash test/hil/hil_ci.sh -b raspberry_pi_pico2 -t host/cdc_msc_hid -r 1
+```
+
+Overrides via env vars: `REMOTE=ci.lan`, `REMOTE_DIR=/tmp/tinyusb-hil`, `CONFIG=test/hil/tinyusb.json`.
+
+The script fails fast if the build dir or repo layout is missing.
+
+## Timing
+
+HIL runs take 2-5 minutes. Use a timeout of at least 20 minutes (600000 ms). NEVER cancel early.
+
+## Reporting results
+
+After the test completes:
+- Show the test output to the user.
+- Summarize pass/fail per board.
+- On failure, suggest re-running with `-v` for verbose output. If `-v` isn't enough, temporarily add debug prints to `test/hil/hil_test.py` to pinpoint the issue.

# TinyUSB Agent Instructions
-TinyUSB is an open-source cross-platform USB Host/Device stack for embedded systems, designed to be memory-safe with no
-dynamic allocation and thread-safe with all interrupt events deferred to non-ISR task functions.
+TinyUSB is a cross-platform USB Host/Device stack for embedded systems: memory-safe (no dynamic allocation) and thread-safe (ISR events deferred to task context).
-Always reference these instructions first and fallback to search or bash commands only when you encounter unexpected
-information that does not match the info here.
+Reference these instructions first; fall back to search/bash only when reality diverges.
-## Shared Ground Rules
-- Keep TinyUSB memory-safe: avoid dynamic allocation, defer ISR work to task context, and follow C99 with two-space indentation/no tabs.
-- Match file organization: core stack under `src`, MCU/BSP support in `hw/{mcu,bsp}`, examples under `examples/{device,host,dual}`, docs in `docs`, tests under `test/{unit-test,fuzz,hil}`.
-- Use descriptive snake_case for helpers, reserve `tud_`/`tuh_` for public APIs, `TU_` for macros, and keep headers self-contained with `#if CFG_TUSB_MCU` guards where needed.
-- Prefer `.clang-format` for C/C++ formatting, run `pre-commit run --all-files` before submitting, and document board/HIL coverage when applicable.
-- Commit in imperative mood, keep changes scoped, and supply PRs with linked issues plus test/build evidence.
+## Behavioral Guidelines
+Bias toward caution over speed. For trivial tasks, use judgment.
-## Bootstrap and Build Setup
+- **Think first** — state assumptions; ask if unclear; present alternatives instead of picking silently.
+- **Simplicity** — no features, abstractions, flexibility, or error handling beyond what was asked. If 200 lines could be 50, rewrite.
+- **Surgical changes** — touch only what the task requires; match existing style; don't refactor working code; mention unrelated dead code rather than deleting it. Remove only orphans *your* changes created.
+- **Goal-driven** — turn tasks into verifiable goals ("write failing test, make it pass"). For multi-step work, state a brief `step → verify` plan.
-- Install ARM GCC toolchain: `sudo apt-get update && sudo apt-get install -y gcc-arm-none-eabi`
-- Fetch core dependencies: `python3 tools/get_deps.py` -- takes <1 second. NEVER CANCEL.
-- For specific board families: `python3 tools/get_deps.py FAMILY_NAME` (e.g., rp2040, stm32f4), or
- `python3 tools/get_deps.py -b BOARD_NAME`
-- Dependencies are cached in `lib/` and `hw/mcu/` directories
-- For **Espressif** boards, initialize the ESP-IDF environment before any build/flash/monitor command:
- `. $HOME/code/esp-idf/export.sh`
+## Ground Rules
-## Build Examples
+- **Language/style:** C99, 2-space indent (no tabs), snake_case helpers, `UPPER_CASE` macros. Public APIs use `tud_`/`tuh_`; macros use `TU_`. Headers self-contained with `#if CFG_TUSB_MCU` guards.
+- **Safety:** no dynamic allocation; defer ISR work to task context; use `TU_ASSERT()` for error checks; always check return values; include order: C stdlib → tusb common → drivers → classes.
+- **Layout:** `src/` core, `hw/{mcu,bsp}/` MCU+BSP, `examples/{device,host,dual}/`, `test/{unit-test,fuzz,hil}/`, `docs/`, `tools/`.
+- **Commits/PRs:** imperative mood, scoped changes, link issues, include test/build evidence.
+- **Formatting/lint:** `clang-format` (`.clang-format`), `codespell` (`.codespellrc`), run `pre-commit run --all-files` before submitting.
-Choose ONE of these approaches:
-**Option 1: Individual Example with CMake and Ninja (RECOMMENDED)**
+## Bootstrap
```bash
-cd examples/device/cdc_msc
-mkdir -p build && cd build
-cmake -DBOARD=raspberry_pi_pico -G Ninja -DCMAKE_BUILD_TYPE=MinSizeRel ..
-cmake --build .
+sudo apt-get install -y gcc-arm-none-eabi # ARM toolchain (2-5 min, one-time)
+python3 tools/get_deps.py [FAMILY|-b BOARD] # fetch deps into lib/, hw/mcu/ (<1 s)
+. $HOME/code/esp-idf/export.sh # Espressif only: before any build/flash/monitor
```
--- takes 1-2 seconds. NEVER CANCEL. Set timeout to 5+ minutes.
-
-**Option 2: All Examples for a Board**
-
-different folder than Option 1
+## Build
+Single example (CMake+Ninja, recommended, 1-3 s):
```bash
-cd examples/
-mkdir -p build && cd build
+cd examples/device/cdc_msc && mkdir -p build && cd build
cmake -DBOARD=raspberry_pi_pico -G Ninja -DCMAKE_BUILD_TYPE=MinSizeRel ..
cmake --build .
```
--- takes 15-20 seconds, may have some objcopy failures that are non-critical. NEVER CANCEL. Set timeout to 30+ minutes.
-
-**Option 3: Individual Example with Make**
-
+All examples for a board (15-20 s; some objcopy failures are non-critical). Use `cmake-build-<board>` as the build dir — HIL tests expect that exact name:
```bash
-cd examples/device/cdc_msc
-make BOARD=raspberry_pi_pico all
+cd examples
+cmake -B cmake-build-raspberry_pi_pico -DBOARD=raspberry_pi_pico -G Ninja -DCMAKE_BUILD_TYPE=MinSizeRel .
+cmake --build cmake-build-raspberry_pi_pico
```
--- takes 2-3 seconds. NEVER CANCEL. Set timeout to 5+ minutes.
-
-**Option 4: Espressif Example with ESP-IDF**
-
-Only ESP-IDF-enabled examples are supported for Espressif boards. Use FreeRTOS examples such as `examples/device/cdc_msc_freertos`
-that contain `idf_component_register()` support.
+Single example with Make:
+```bash
+cd examples/device/cdc_msc && make BOARD=raspberry_pi_pico all
+```
+Espressif (only ESP-IDF examples like `cdc_msc_freertos`):
```bash
. $HOME/code/esp-idf/export.sh
cd examples/device/cdc_msc_freertos
idf.py -DBOARD=espressif_s3_devkitc build
```
-Use `-DBOARD=...` with any supported board under `hw/bsp/espressif/boards/`. NEVER CANCEL. Set timeout to 10+ minutes.
-

-### RTT Logging with JLinkGDBServer
-
-- Build with RTT logging enabled (example):
- `cd examples/device/cdc_msc && make BOARD=stm32h743eval LOG=2 LOGGER=rtt all`
-- Flash with J-Link:
- `cd examples/device/cdc_msc && make BOARD=stm32h743eval LOG=2 LOGGER=rtt flash-jlink`
-- Launch GDB server with RTT port (keep this running in terminal 1):
- `JLinkGDBServer -device stm32h743xi -if SWD -speed 4000 -port 2331 -swoport 2332 -telnetport 2333 -RTTTelnetPort 19021 -nogui`
-- Read RTT output (terminal 2):
- `JLinkRTTClient`
-- Capture RTT to file (optional):
- `JLinkRTTClient | tee rtt.log`
-- For non-interactive capture:
- `timeout 20s JLinkRTTClient > rtt.log`
-
-## Unit Testing
-
-- Install Ceedling: `sudo gem install ceedling`
-- Run all unit tests: `cd test/unit-test && ceedling` or `cd test/unit-test && ceedling test:all` -- takes 4 seconds.
- NEVER CANCEL. Set timeout to 10+ minutes.
-- Run specific test: `cd test/unit-test && ceedling test:test_fifo`
-- Tests use Unity framework with CMock for mocking
-
-## Hardware-in-the-Loop (HIL) Testing
-
-- `-B examples` means `examples` is the parent folder that contains multi-board build outputs such as `examples/cmake-build-BOARD_NAME/...`
-- Select config file before running HIL tests:
- - if GitHub Actions self-hosted runner service is running, use `tinyusb.json`
- - otherwise use `local.json`
- - example:
- `HIL_CONFIG=$( (systemctl list-units --type=service --state=running 2>/dev/null; systemctl --user list-units --type=service --state=running 2>/dev/null) | grep -q 'actions\.runner' && echo tinyusb.json || echo local.json )`
-- Run tests on actual hardware, one of following ways:
- - test a specific board `python test/hil/hil_test.py -b BOARD_NAME -B examples $HIL_CONFIG`
- - test all boards in config `python test/hil/hil_test.py -B examples $HIL_CONFIG`
-- In case of error, enabled verbose mode with `-v` flag for detailed logs. Also try to observe script output, and try to
- modify hil_test.py (temporarily) to add more debug prints to pinpoint the issue.
-- Requires pre-built (all) examples for target boards (see Build Examples section 2)
-
-take 2-5 minutes. NEVER CANCEL. Set timeout to 20+ minutes.
-
-## Documentation
-
-- Install requirements: `pip install -r docs/requirements.txt`
-- Build docs: `cd docs && sphinx-build -b html . _build` -- takes 2-3 seconds. NEVER CANCEL. Set timeout to 10+ minutes.
+**RTT logging:** build with `LOG=2 LOGGER=rtt`, flash, then run JLinkGDBServer with `-RTTTelnetPort 19021`, and in another terminal `JLinkRTTClient` (pipe to `tee rtt.log` or use `timeout 20s JLinkRTTClient > rtt.log` for non-interactive capture).
-## Code Size Metrics
-
-Generate and compare code size metrics to evaluate the impact of changes. This is the most common workflow
-when making code changes — use it to verify size impact before committing.
-
-**Quick single-board metrics (preferred for iterative development):**
+## Testing
+**Unit (Ceedling, Unity+CMock, ~4 s):**
```bash
-rm -rf cmake-build
-python3 tools/build.py -b raspberry_pi_pico --target all --target tinyusb_metrics
-python3 tools/metrics.py combine -j -m -f tinyusb/src cmake-build/cmake-build-*/metrics.json
+sudo gem install ceedling
+cd test/unit-test && ceedling test:all # or ceedling test:test_fifo
```
-This builds all examples for one board and produces `metrics.json` + `metrics.md`. Takes ~30 seconds.
-NEVER CANCEL. Set timeout to 10+ minutes.
-
-**Comparing with master (before/after workflow):**
+**HIL (2-5 min):** invoke the `hil` skill (`.claude/skills/hil/SKILL.md`) for the full procedure (local vs remote mode, config selection, SSH copy steps, debugging tips). Requires pre-built examples — see Build → "All examples for a board".
-1. On master: build and save baseline
- ```bash
- rm -rf cmake-build
- python3 tools/build.py -b raspberry_pi_pico --target all --target tinyusb_metrics
- python3 tools/metrics.py combine -j -m -f tinyusb/src cmake-build/cmake-build-*/metrics.json
- mv metrics.json metrics_master.json
- ```
-2. Switch to your branch: rebuild
- ```bash
- rm -rf cmake-build
- python3 tools/build.py -b raspberry_pi_pico --target all --target tinyusb_metrics
- python3 tools/metrics.py combine -j -m -f tinyusb/src cmake-build/cmake-build-*/metrics.json
- ```
-3. Compare: `python3 tools/metrics.py compare -m -f tinyusb/src metrics_master.json metrics.json`
- Produces `metrics_compare.md` showing size differences.
-
-**Full CI metrics (all arm-gcc families, for thorough validation):**
+## Documentation
```bash
-rm -rf cmake-build
-FAMILIES=$(python3 .github/workflows/ci_set_matrix.py | python3 -c "import sys,json; d=json.load(sys.stdin); print(' '.join(d.get('arm-gcc',[])))")
-python3 tools/build.py --one-first --target all --target tinyusb_metrics $FAMILIES
-python3 tools/metrics.py combine -j -m -f tinyusb/src cmake-build/cmake-build-*/metrics.json
+pip install -r docs/requirements.txt
+cd docs && sphinx-build -b html . _build # ~2.5 s
```
-Builds the first board of each family. Takes 2-4 minutes. NEVER CANCEL. Set timeout to 10+ minutes.
-
-## Code Quality and Validation
+## Code Size Metrics
-- Format code: `clang-format -i path/to/file.c` (uses `.clang-format` config)
-- Check spelling: `pip install codespell && codespell` (uses `.codespellrc` config)
-- Pre-commit hooks validate unit tests and code quality automatically
+Verify size impact before committing. Invoke the `code-size` skill (`.claude/skills/code-size/SKILL.md`) — it wraps `tools/metrics_compare_base.py` to handle the base-vs-branch worktree + build + compare flow.
-## Static Analysis with PVS-Studio
+Quick reference:
+```bash
+# Single example, one board:
+python3 tools/metrics_compare_base.py -b raspberry_pi_pico -e device/cdc_msc
+# Add --bloaty for section/symbol breakdown.
-- **Analyze whole project**:
- ```bash
- pvs-studio-analyzer analyze -f examples/cmake-build-raspberry_pi_pico/compile_commands.json -R .PVS-Studio/.pvsconfig -o pvs-report.log -j12 --dump-files --misra-cpp-version 2008 --misra-c-version 2023 --use-old-parser
- ```
-- **Analyze specific source files**:
- ```bash
- pvs-studio-analyzer analyze -f examples/cmake-build-raspberry_pi_pico/compile_commands.json -R .PVS-Studio/.pvsconfig -S path/to/file.c -o pvs-report.log -j12 --dump-files --misra-cpp-version 2008 --misra-c-version 2023 --use-old-parser
- ```
-- **Multiple specific files**:
- ```bash
- pvs-studio-analyzer analyze -f examples/cmake-build-raspberry_pi_pico/compile_commands.json -R .PVS-Studio/.pvsconfig -S src/file1.c -S src/file2.c -o pvs-report.log -j12 --dump-files --misra-cpp-version 2008 --misra-c-version 2023 --use-old-parser
- ```
-- Requires `compile_commands.json` in the build directory (generated by CMake with `-DCMAKE_EXPORT_COMPILE_COMMANDS=ON`)
-- Use `-f` option to specify path to `compile_commands.json`
-- Use `-R .PVS-Studio/.pvsconfig` to specify rule configuration file
-- Use `-j12` for parallel analysis with 12 threads
-- `--dump-files` saves preprocessed files for debugging
-- `--misra-c-version 2023` enables MISRA C:2023 checks
-- `--misra-cpp-version 2008` enables MISRA C++:2008 checks
-- `--use-old-parser` uses legacy parser for compatibility
-- Analysis takes ~10-30 seconds depending on project size. Set timeout to 5+ minutes.
-- View results: `plog-converter -a GA:1,2 -t errorfile pvs-report.log` or open in PVS-Studio GUI
+# All examples, one board:
+python3 tools/metrics_compare_base.py -b raspberry_pi_pico
-## Validation Checklist
+# All arm-gcc CI families combined (pre-merge sweep, 4-8 min):
+python3 tools/metrics_compare_base.py --ci
+```
-### ALWAYS Run These After Making Changes
+Reports land in `cmake-metrics/<board>/metrics_compare.md` (per-board) and `cmake-metrics/_combined/metrics_compare.md` (with `--combined`/`--ci`).
-1. **Pre-commit validation** (RECOMMENDED): `pre-commit run --all-files`
- - Install pre-commit: `pip install pre-commit && pre-commit install`
- - Runs all quality checks, unit tests, spell checking, and formatting
- - Takes 10-15 seconds. NEVER CANCEL. Set timeout to 15+ minutes.
-2. **Build validation**: Build at least one board with all example that exercises your changes, see Build Examples
- section (option 2)
-3. Run unit tests relevant to touched modules; add fuzz/HIL coverage when modifying parsers or protocol state machines.
+## Static Analysis (PVS-Studio)
-### Manual Testing Scenarios
-- **Device examples**: Cannot be fully tested without real hardware, but must build successfully
-- **Unit tests**: Exercise core stack functionality - ALL tests must pass
-- **Build system**: Must be able to build examples for multiple board families
+Requires `compile_commands.json` (CMake `-DCMAKE_EXPORT_COMPILE_COMMANDS=ON`).
-### Board Selection for Testing
-- **STM32F4**: `stm32f407disco` - no external SDK required, good for testing
-- **RP2040**: `raspberry_pi_pico` - requires Pico SDK, commonly used
-- **Other families**: Check `hw/bsp/FAMILY/boards/` for available boards

-1. Bump the release version variable at the top of `tools/make_release.py`.
-2. Execute `python3 tools/make_release.py` to refresh:
- - `src/tusb_option.h` (version defines)
- - `repository.yml` (version mapping)
- - `library.json` (PlatformIO version)
- - `sonar-project.properties` (SonarQube version)
- - `docs/reference/boards.rst` (generated board documentation)
- - `hw/bsp/BoardPresets.json` (CMake presets)
-3. Generate release notes for `docs/info/changelog.rst`:
- - Get commit list: `git log <last-release-tag>..HEAD --oneline`
- - **Visit GitHub PRs** for merged pull requests to understand context and gather details
- - Use GitHub tools to search/read PRs: `github-mcp-server-list_pull_requests`, `github-mcp-server-pull_request_read`

- - Add new changelog entry following the existing format:
- - Version heading with equals underline (e.g., `0.20.0` followed by `======`)
- - Release date in italics (e.g., `*November 19, 2024*`)
- - Major sections: General, API Changes, Controller Driver (DCD & HCD), Device Stack, Host Stack, Testing
- - Use bullet lists with descriptive categorization
- - Reference function names, config macros, and file paths using RST inline code (double backticks)
- - Include meaningful descriptions, not just commit messages
-4. **Validation before commit**:
- - Run unit tests: `cd test/unit-test && ceedling test:all`
- - Build at least one example: `cd examples/device/cdc_msc && make BOARD=stm32f407disco all`
- - Verify changed files look correct: `git diff --stat`
-5. **Leave files unstaged** for maintainer to review, modify if needed, and commit with message: `Bump version to X.Y.Z`
-6. **After maintainer commits**: Create annotated tag with `git tag -a vX.Y.Z -m "Release X.Y.Z"`
-7. Push commit and tag: `git push origin <branch> && git push origin vX.Y.Z`
-8. Create GitHub release from the tag with changelog content

+## Validation After Changes
-#### Build Time Reference
-- **Dependency fetch**: <1 second
-- **Single example build**: 1-3 seconds
-- **Unit tests**: ~4 seconds
-- **Documentation build**: ~2.5 seconds
-- **Full board examples**: 15-20 seconds
-- **Toolchain installation**: 2-5 minutes (one-time)
+1. `pre-commit run --all-files` — format, spell, unit tests (10-15 s).
+2. Build at least one board's full example set (Build → "All examples for a board") for modules you touched.
+3. Run relevant unit tests; add fuzz/HIL coverage for parsers or protocol state machines.
-#### Key Files to Know
-- `tools/get_deps.py`: Manages dependencies for MCU families
-- `tools/build.py`: Builds multiple examples, supports make/cmake
-- `src/tusb.h`: Main TinyUSB header file
-- `src/tusb_config.h`: Configuration template
-- `examples/device/cdc_msc/`: Most commonly used example for testing
-- `test/unit-test/project.yml`: Ceedling test configuration
+**Boards good for local testing:**
+- `stm32f407disco` — no external SDK
+- `raspberry_pi_pico` — Pico SDK required
+- Others: see `hw/bsp/FAMILY/boards/`
-#### MCU Reference Manuals and Datasheets
-- Look in `$HOME/Documents/Calibre Library` for all MCU reference manuals, datasheets and board schematics.
+Device examples need real hardware to validate runtime behavior; must at least build.
-#### Debugging Build Issues
-- **Missing compiler**: Install `gcc-arm-none-eabi` package
-- **Missing dependencies**: Run `python3 tools/get_deps.py FAMILY`
-- **Board not found**: Check `hw/bsp/FAMILY/boards/` for valid board names
-- **objcopy errors**: Often non-critical in full builds, try individual example builds
+## Release
-#### Working with USB Device Classes
-- **CDC (Serial)**: `src/class/cdc/` - Virtual serial port
-- **HID**: `src/class/hid/` - Human Interface Device (keyboard, mouse, etc.)
-- **MSC**: `src/class/msc/` - Mass Storage Class (USB drive)
-- **Audio**: `src/class/audio/` - USB Audio Class
-- Each class has device (`*_device.c`) and host (`*_host.c`) implementations
+**Do not commit automatically — leave changes for maintainer review.**
-#### MCU Family Support
-- **STM32**: Largest support (F0, F1, F2, F3, F4, F7, G0, G4, H7, L4, U5, etc.)
-- **Raspberry Pi**: RP2040, RP2350 with PIO-USB host support
-- **NXP**: iMXRT, Kinetis, LPC families
-- **Microchip**: SAM D/E/G/L families
-- Check `hw/bsp/` for complete list and `docs/reference/boards.rst` for details
+1. Bump version at top of `tools/make_release.py`.
+2. Run `python3 tools/make_release.py` to refresh: `src/tusb_option.h`, `repository.yml`, `library.json`, `sonar-project.properties`, `docs/reference/boards.rst`, `hw/bsp/BoardPresets.json`.
+3. Changelog `docs/info/changelog.rst`:
+ - `git log <last-tag>..HEAD --oneline` for commit list.
+ - Read merged PRs for context (`gh pr view`, or github MCP tools).
+ - Follow existing format: version + `======` underline, italic date, sections (General, API Changes, DCD & HCD, Device Stack, Host Stack, Testing), RST inline code for symbols.
+4. Validate: `ceedling test:all`, build `cdc_msc` for `stm32f407disco`, review `git diff --stat`.
+5. Leave unstaged. Maintainer commits `Bump version to X.Y.Z`, then: `git tag -a vX.Y.Z -m "Release X.Y.Z" && git push origin <branch> vX.Y.Z`. Create GitHub release from tag.
-### Code Style Guidelines
+## References
-#### General Coding Standards
-- Use C99 standard
-- Memory-safe: no dynamic allocation
-- Thread-safe: defer all interrupt events to non-ISR task functions
-- 2-space indentation, no tabs
-- Use snake_case for variables/functions
-- Use UPPER_CASE for macros and constants
-- Follow existing variable naming patterns in files you're modifying
-- Include proper header comments with MIT license
-- Add descriptive comments for non-obvious functions
+- MCU reference manuals, datasheets, schematics: `$HOME/Documents/Calibre Library`.
+- Supported MCUs/boards: `hw/bsp/` and `docs/reference/boards.rst`.
+- USB classes: `src/class/{cdc,hid,msc,audio,…}/` — each has `*_device.c` and `*_host.c`.
+- Key files: `src/tusb.h`, `src/tusb_config.h`, `tools/get_deps.py`, `tools/build.py`, `test/unit-test/project.yml`.
-#### Best Practices
-- When including headers, group in order: C stdlib, tusb common, drivers, classes
-- Always check return values from functions that can fail
-- Use TU_ASSERT() for error checking with return statements
-- Follow the existing code patterns in the files you're modifying
+## Common Build Issues
-Remember: TinyUSB is designed for embedded systems - builds are fast, tests are focused, and the codebase is optimized for resource-constrained environments.
+- Missing compiler → install `gcc-arm-none-eabi`.
+- Missing deps → `python3 tools/get_deps.py FAMILY`.
+- Unknown board → check `hw/bsp/FAMILY/boards/`.
+- `objcopy` errors in full builds are often non-critical; retry the single example.
