hil, ci: scope HIL builds and tests to the boards a PR affects (#3797)

2026-07-29T19:29:32Z

hil, ci: scope HIL builds and tests to the boards a PR affects Add test/hil/hil_select.py, a stdlib-only selector that maps a PR diff to the rig boards, tests and BSP families a change can affect, and wire it into CI so pull requests build and run only those. A port change picks its families' boards, a class change picks the examples enabling that class, and device/host changes prune the other role. Anything unclassified — infra, an unmapped port, a selector error — falls back to the full matrix, and push/schedule runs are untouched. Move the shared example lists to hil_examples.py; 54 hardware-free tests cover the rules.

hil: split hil_test.py into hil_lock/hil_flash, add pool_check, update rig probes (#3794)

2026-07-29T10:29:59Z

test/hil: add board-pool health check, split hil_test into focused modules (#3794) Add test/hil/hil_pool_check.py: per-board rig health scan — probe presence, light-example flash (dfu_runtime; device_info + serial check for host-only boards), uid re-enumeration, safe recovery (probe authorized-toggle, board reset), verified board_test re-park, USB topology report, and a markdown summary table. Missing firmware is built on the spot (tools/build.py, idf.py for espressif, one get_deps retry); row statuses: ok, flash-failed, failed, locked. Board locks are always respected, never bypassed. Refactor hil_test.py into hil_lock.py (flock protocol, controller permits, hold/release/status CLI; replaces board_lock.py) and hil_flash.py (flashers, find_firmware, run_cmd). Update WCH probe uids and the board roster in tinyusb.json; add the hil-pool-check skill.

docs(skills): formatting feedback — agent skill table, probe bullets, aligned columns

2026-07-24T07:55:59Z

- target-debugger: skill list is now a table referencing skills by name only (path pattern stated once). - target-debug: probe-mapping run-on paragraph split into bullets; drop the GDB Ninth-Edition caveat (calibre now holds the Tenth-Edition PDF, id 2264). - Align markdown table columns across target-debug, usb-sniffer, usbmon, hil, usbtest and the agent (7 tables); tables with paragraph-length cells left unpadded (usbmon symptom map, usbtest case map).

docs: add read-doc skill, tighten CLAUDE.md and skill docs (#3778)

2026-07-21T11:06:01Z

* docs: add read-doc skill for on-demand datasheet lookup Search and read MCU datasheets, reference manuals, errata, and the USB spec from a local Calibre library ($HOME/Documents/calibre-library) instead of answering register/bitfield/pinout questions from model memory. Gated on the library's existence, so it no-ops for contributors who don't have it. * docs: reference read-doc skill and tighten CLAUDE.md Point the datasheet/reference entry at the new read-doc skill, and trim sections that only duplicate a skill already owning the detail: PVS-Studio and Code Size collapse to pointers; GDB/Build/Flash command blocks condensed to essentials. 213 -> 129 lines; behavioral guidelines and the validation checklist unchanged. * docs: tighten skill redundancy; rename AGENTS.md refs to CLAUDE.md code-size: fold the step list into a sentence and drop invocation examples the argument tables already cover. hil: merge the duplicated self-lock bullets and compress the hifiphile note. usbmon: compress the group-membership setup paragraph. All commands, flags, lock rules, and report paths preserved. usb-target-debug and the pvs script only get stale AGENTS.md references renamed to CLAUDE.md (now the real file); run_pvs.sh no longer cites a --dump-files mention that CLAUDE.md dropped. * docs: fix review findings — restore Espressif cd step, ELF placeholder, code-size comment Codex/Copilot/Claude review of #3778: the condensed Espressif bullet lost its cd (idf.py resolves the project from CWD, so the command failed from repo root); the GDB example now uses the build/your_app.elf placeholder that docs/troubleshooting.rst established; the code-size invocation comment no longer references --combined, which the shown command doesn't use.

dcd(ci_hs): stale overlay fix; run usbtest on lpcxpresso43s67

2026-07-14T08:23:07Z

- dcd_edpt_stall flushes the primed buffer (ENDPTFLUSH), but the aborted transfer's dQH overlay can be left ACTIVE with mid-transfer state; the next prime after clear-halt then resumes the stale overlay instead of loading the fresh qtd, so post-halt IN reads return mid-buffer data (usbtest case 13 'buf[32] = 56 (not 0)', with case 18 failing downstream of the same corruption in the full battery). qhd_start_xfer now clears overlay.active alongside overlay.halted before linking the new qtd. - test/hil(hfp): drop lpcxpresso43s67's device/usbtest skip - the historical first-case wedge no longer reproduces on this branch, and with the overlay fix the board runs 30/30 on its Fresco xHCI host (previously 28/30 with deterministic case 13/18 failures). mimxrt1064_evk (imxrt dcache path) 30/30 regression-clean. - docs(hil skill): document the external hifiphile rig - pool test/hil/hfp.json, SSH-reachable from htpc/ci with no outbound SSH, exercised by the CI hil-tinyusb (hfp.json) job; never run HIL against it during development unless the user explicitly asks.

Fix max-effort review findings in lock protocol, workflows, and docs

2026-07-13T11:01:07Z

Confirmed by a 10-finder / 28-verifier adversarial review pass: board_lock.py — the flock is now the sole authority: drop cmd_hold's pid-liveness pre-gate (a live hil_test.py pool worker's stale record no longer blocks a genuinely free board); cmd_release probes the flock and only signals a verified holder, refuses to kill hil_test.py holders (CI mid-test), handles PermissionError; the holder daemon truncates its lock records on SIGTERM and keeps the success pipe clear of fds 0-2 (closed-stdio hold used to leave an orphan holder while reporting failure); --config default resolves beside the script. hil_test.py — truncate the lock record on per-board release (pool workers outlive their flocks); warn instead of silently failing open when the lock dir is unusable; error out on -b names absent from the config (was a silent zero-test exit 0, readable as a green HIL run); drop an emptied board row in accumulate_report (variant boards left a blank ghost row). workflows — remove the stray positional arg that made the validate size stage exit 2 on every run; wrap JSON.parse(args) in all six scripts; factor pr-babysit's drifted reply recipe into postReplyRecipe and dedup refutation replies across cycles; validate args.pr and maxCycles; driver-review rejects an empty dimensions list; hil-validate drops a dead guard clause and retries diagnostics with -v -r 1. agents/docs — port-dev scopes git clang-format to its own files (concurrent workers reformatted each other in shared checkouts); hil-operator/hil skill wording matches actual fail-fast output; the implementation plan is now a DO-NOT-EXECUTE historical record (banner + checked boxes) so plan-executing agents cannot revert shipped files. Verified: lock storm 1-winner-in-10, stale-record hold, closed-stdio hold, dead-pid cleanup, CI-holder refusal, ghost-row 4-scenario merge, unknown-board exit 1, py_compile + check.sh on all six workflows, pre-commit clean.

feat: Claude Code multi-agent dev/test harness for TinyUSB

2026-07-09T16:34:29Z

Add worker agents (builder, port-dev, driver-reviewer, hil-operator, pr-monitor), deterministic workflows (validate, fanout-dev, driver-review, hil-validate, full-check, pr-babysit) and a /pre-pr gate skill, so sessions can fan build/test/review/PR-triage work out to tiered subagents. pr-babysit drives a PR to green: triage CI + bot reviews, fix validated findings, verify, push, and reply-to + resolve each inline review thread (fixed or refuted). Replace the stop-the-runner HIL discipline with per-board flock locks: test/hil/board_lock.py plus a fail-open guard in hil_test.py let CI and dev sessions share the rig per board (locked boards fail fast and re-run; HIL_NO_BOARD_LOCK=1 is a user-authorized bypass). The actions-runner is never stopped. Design spec, implementation plan, and real-rig smoke evidence under docs/superpowers/.

ci: address second codex/copilot review round

2026-06-01T17:24:05Z

- claude.yml: drop the issues "assigned" trigger; its author_association gate keys on the issue author, not the assigner, so a maintainer assigning an outside contributor's issue would be wrongly skipped. - claude-code-review.yml: issues: read -> write so use_sticky_comment can create/update its PR comment via the issues API. - hil SKILL.md: make local/remote command blocks copy-pasteable (drop [-b BOARD_NAME] notation for concrete examples) and fix timeout (600000 ms is 10 min; use 1200000 ms for the stated 20 min).
