serial-arduino SKILL.md skillA
serial-arduino from michelbr84/garrarust is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add michelbr84/garrarust/serial-arduino@git:20260913.38a8ac8Pins git:20260913.38a8ac8 in mdr.lock. Pin the fingerprint instead.

Adapter oficial Serial/USB — placas Arduino e compatíveis falando o protocolo JSONL de linha, com o firmware de referência versionado no repo.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Serial / Arduino A ponte direta: uma placa plugada no cabo USB, falando JSON por linha. ## O que este skill declara - `transport: serial` — o core (`garraia-hardware`, feature `hardware-serial`) abre a porta, faz o handshake e lê/escreve JSONL; - as quatro capabilities da tabela **fechada** de periféricos. ## Firmware de referência O sketch está em `crates/garraia-hardware/examples/firmware/` — é código Arduino/C++, não um alvo Cargo. ## Risco: a tabela é fechada, e por quê Ao contrário do MQTT, aqui o risco **não** vem do dispositivo. Uma placa plugada num cabo USB não passou por ACL nenhuma, então ela não pode ser a fonte da própria classificação: `digital_read` e `analog_read` são R0, `digital_write` e `pwm` são R2, e isso está no código (`garraia_hardware::perifericos`), não no manifesto que a placa envia. O id que a placa declara também não vira chave de registry sozinho: ele sai como `serial:<id>` e o registro usa `register_if_absent`, então uma segunda placa não sequestra as leituras endereçadas à primeira. ## Editar para a sua bancada Troque `entity: bancada` pelo id que o seu firmware declara no handshake.

How to install
mdr add michelbr84/garrarust/serial-arduino@sha256:bf1f48e247c2991fThe line at the top of this page pins the label git:20260913.38a8ac8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
