Changelog

All notable changes to the arduino-skills project are documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

No unreleased changes.

[1.8.0] - 2026-08-17

Added

  • sensor-signal-filtering for ADC/sensor signal-chain diagnosis, software filter selection, analog RC/input conditioning, host-side TDD, hardware measurement gates, and progressive-disclosure references.
  • A standard-library filter benchmark helper, diagnostic ADC example, focused host tests, trigger/evaluation cases, and a repository CI workflow.

Changed

  • Routed ADC/sensor filtering requests through board support, wiring safety, and calibration only after signal detection is established; reusable filtering snippets remain owned by arduino-code-generator.
  • Local Loop Engine snapshots are ignored by .gitignore; release evidence is retained in the tracked research, plan, review, ledger, and final-report artifacts.

Verification

  • 30 skills, 8/8 shared contract themes, 9 board profiles, and 20/20 forward cases pass their deterministic validators.
  • 7/7 focused host tests and the official plugin validator pass.
  • Representative Arduino CLI build artifacts were produced for Uno, Uno R4 WiFi, ESP32, Pico W, and UNO Q.
  • Model activation and physical hardware validation remain unverified.

[1.7.0] - 2026-08-11

Added

  • board-support, an AI-facing exact-board lookup skill that resolves indexed profiles, source status, capability/risk boundaries, framework/toolchain scope, ambiguity, unsupported targets, and pin-assignment handoff.
  • references/boards/ai-reference-schema.md and schema version 3 summaries in references/boards/index.json for aliases, MCU/architecture, logic level, capability tags, risk tags, identity scope, variant identity contracts, toolchains, and evidence status.
  • A deterministic scripts/resolve_board_profile.py helper that returns exact, unsupported, or identity-incomplete results without fuzzy matching.
  • Variant-boundary and resolution-envelope scenarios; the forward suite now covers 18/18 cases, plus a held-out 20-query trigger corpus.
  • Cross-profile lookup-key, evidence-confidence, and checked-date hardening in the board validator and eval harness.
  • Durable Wayfinder and loop-engine records under docs/workflows/arduino-board-agent-skill-2026-08-11/.

Changed

  • arduino-workflow-router now loads board-support for named-board facts before pin assignment, while requirement-level board choice remains owned by board-selection.
  • pin-assignment now requires a resolved board-support handoff before physical pin selection.
  • board-selection now owns board choice/replacement only and consumes the board-support profile instead of duplicating lookup behavior.
  • Board-reference validation now fails closed when AI retrieval fields, structured identity contracts, or explicit physical_status: unverified evidence are missing.
  • README, design principles, shared contract, board docs, and eval results now describe the board-support entry point, compact reference surface, resolver, and package-context installation boundary.

Flagged

  • Four delegated research agents and two fresh semantic reviewers were initially unavailable because of upstream 503/timeout failures. One delayed fresh reviewer returned actionable findings; the retry batch still failed. Deterministic gates pass, but model activation rates remain unrun.
  • The board-support skill intentionally depends on the complete repository/plugin for shared profiles, contract, and resolver; standalone per-skill copies are unsupported and documented as such.
  • No board was wired, flashed, compiled for target hardware, powered, measured, or deployed in this loop. GIGA R1 WiFi and ESP32-C6 remain deferred.

Planned

  • GitHub Actions CI pipeline for Arduino compilation and Python script validation
  • GitHub branch protection rules and status checks
  • Skill validation test suite (schema checking, YAML parsing)

[1.6.0] - 2026-08-11

Added

  • Mainstream plugin packaging: portable plugin.json, Codex .codex-plugin/plugin.json and marketplace entry, Claude Code and Cursor adapters, and thin AGENTS.md, CLAUDE.md, and GEMINI.md wrappers.
  • pin-assignment, board-selection, wiring-safety-check, non-blocking-patterns, library-selection, memory-budgeting, hardware-tdd, and embedded-project-loop skills.
  • Board reference index and profiles for Uno R3/R4, classic ESP32/WROOM, ESP32-S3, and Pico/Pico W; skill-gap and loop-layer research reports.
  • Deterministic plugin, behavioral, regression, and board-source eval tooling under scripts/ and evals/.
  • Declarative forward-contract cases for all ten representative prompts, including route order, trigger precedence, shared output sections, and the required pin, wiring, and blocked-gate scenarios.
  • A dated board source ledger with fact-to-source mappings and immutable commit pins for the Arduino-ESP32 and Arduino-Pico variant references.
  • Four additional source-backed board profiles: Arduino Mega 2560 Rev3, Arduino Nano Every, Arduino Nano ESP32, and ESP32-C3-DevKitC-02.
  • A machine-readable references/boards/index.json inventory and a discoverable scripts/validate_board_references.py gate for profile fields, official source URLs, fact maps, explicit gaps, and source-ledger coverage.
  • A dedicated loop-engine-evidence-contract evaluation with valid and fail-closed invalid durable-loop fixtures for embedded-project-loop.
  • Online research notes for Agent Skills frontmatter, progressive disclosure, composable skills, and loop-engineering evidence boundaries.

Changed

  • Refined arduino-workflow-router to route combined workflows through board selection, pin/wiring safety, library/memory, timing, testing, and durable physical gates.
  • Refined arduino-serial-monitor to own structured serial debugging rather than adding an overlapping serial skill.
  • Corrected the ESP32-S3 research reference to avoid applying classic ESP32 GPIO34-39 input-only behavior to S3 without checking the exact module.
  • Corrected Codex marketplace source metadata to the documented local source object, made the serial helper self-contained with PEP 723 dependencies, repaired a malformed Markdown output-contract fence, and added trigger metadata to every active skill.
  • Made the serial monitor's optional imports lazy so --help works with the host Python runtime, and added resumable long-run manifest, backlog, sprint, heartbeat, and resume-token artifacts for this refinement.
  • Removed stale per-skill Claude marketplace files so root provider adapters are the only discovery metadata surface; corrected the release push example to use v1.6.0.
  • Expanded the board matrix without changing the five existing profile files; the plugin validator now retains its legacy checks and consumes the dynamic board index as an additional gate.
  • Made embedded-project-loop the recommended first skill for physical, recovery, measurement, and multi-session work, with the router following it for specialist selection.
  • Updated the shared contract, README, contributor/development guides, plugin distribution notes, eval inventory, and release notes for the loop contract.
  • Published the v1.6.0 release tag and GitHub Release from the existing v1.5.0 baseline after the deterministic gate suite passed.

Skipped

  • No separate serial-debugging skill: the existing serial monitor remains the single owner for runtime serial evidence.
  • No physical board flashing, wiring, measurement, or global skill replacement was performed.

Flagged conflicts

  • The requested /Users/wed/.agents/skills/arduino/ directory does not exist; the repository skills/ tree is the canonical source and the five existing global Arduino sibling skills were left untouched.
  • Codex marketplace and legacy manifest behavior is release-sensitive; the package includes both the documented .codex-plugin adapter and portable root metadata, with validation evidence recorded for the installed schema.
  • Product pages without immutable public revisions, exact board/module variants, and aggregate board-current limits remain explicitly date-checked or unverified rather than being guessed over.
  • Arduino GIGA R1 WiFi and ESP32-C6-DevKitC-1 were deferred from this bounded loop. They remain candidates for a later profile after a separate source and core-variant review; they are not silently treated as supported here.
  • Four bounded fresh-context post-repair reviewer attempts produced no verdict artifact; this is an evaluator-availability blocker, not a passing review.

Research basis

  • Agent Skills specification and best practices: agentskills.io.
  • Local skill-creator, plugin-creator, loop-engine, and long-run-harness-execution contracts.
  • Official Arduino, Espressif, Raspberry Pi, and Arduino-core board sources; source ledger and unresolved board-family gaps are in references/boards/.

Existing baseline additions

  • arduino-workflow-router for board/toolchain intake and combined embedded workflows across firmware, electronics, power, networking, enclosure, deployment, and maintenance.

  • Shared board profile, lifecycle/evidence, output, recovery, security, and maintenance references.

  • scripts/validate_arduino_skill_contract.py for deterministic cross-skill review coverage checks.

  • Updated all active skills and contributor docs to name assumptions, tools and versions, implementation steps, evidence stages, limitations, and recovery or security notes.

  • Installed the distinct official OpenAI cli-creator and plugin-creator companions globally for Codex without overwriting the existing skill-creator.
