Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00068 | $0.00598 |
| Opus 5 | $0.00034 | $0.00299 |
| Sonnet 5 | $0.00014 | $0.00120 |
| Haiku 4.5 | $0.00007 | $0.00060 |
Grade A, and why
arduino-cli-skill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Arduino CLI Skill
Provide cross-platform arduino-cli workflows and command references.
Resources
references/commands.md- board, core, library, compile, and upload commandsreferences/serial-ports.md- OS-specific serial port discoveryrules/common-pitfalls.md- common command mistakes and recovery guidanceexamples/README.md- runnable command sequences../../docs/board-support/uno-r4-family.md- Uno R4 Minima and Uno R4 WiFi support notes
Workflow
- Identify the user's platform and target board.
- Open
references/serial-ports.mdif the task depends on port discovery. - Open
references/commands.mdfor the exact command family you need. - Check
rules/common-pitfalls.mdbefore suggesting upload or compile fixes. - If the target is Uno R4 family and the problem touches WiFi, firmware bridge,
or OTA-related setup, open
../../docs/board-support/uno-r4-family.md. - Prefer
arduino-cliJSON output when the result will be parsed or reused.
Compatibility And Proof Boundary
Record arduino-cli version, the core/index version, FQBN, libraries, host OS,
and port before changing commands. Check library architecture support and board
package compatibility. A successful compile is build proof only; an accepted
upload is upload proof and does not establish hardware or system success. For
IDE, PlatformIO, or vendor-specific commands, route to the appropriate branch
instead of silently translating them.
Quick Start
arduino-cli board list
arduino-cli core list
arduino-cli compile --fqbn arduino:avr:uno path/to/sketch
arduino-cli upload -p /dev/ttyACM0 --fqbn arduino:avr:uno path/to/sketch
Verification
- Confirm the
fqbnmatches the target board. - Confirm the selected serial port exists before upload.
- Prefer command output over remembered defaults when troubleshooting.
See references/commands.md and references/serial-ports.md for detailed examples.
Shared Output Contract
Use the shared Arduino skill contract: state assumptions, required tools and versions, implementation steps, tests/evidence by proof stage, known limitations, and recovery/security notes.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

arduino-cli-skill is a skill published in the GitHub repository wedsamuel1230/arduino-skills (21 stars, last pushed 23d ago), licensed MIT. It adds 68 tokens to every session and 598 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
