platformio-mcp: Skill for Claude Code

.skills/get-started/SKILL.md

get-started is a skill for Claude Code, Codex from jl-codes/platformio-mcp. It costs 52 tokens per session (308 once invoked), scanned A, original, MIT.

A first-run guide for PlatformIO projects, which are projects for building software for connected hardware. It checks the local setup and inspects the selected project without automatically changing or programming a device.

In plain words
What is it for?
Use it to verify the PlatformIO agent, inspect project environments and dependencies, check connected devices when needed, and choose a next step.
Why use it?
It helps identify missing prerequisites and understand a project before any build or hardware action is taken.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: mentions Codex.

This is jl-codes/platformio-mcp's own configuration. It tells Claude Code and Codex how to work on platformio-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything platformio-mcp configures →

Token cost

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.

Security

Grade A, and why

get-started 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 27d 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.

What it actually says

Get started with PIO Agent

Help the user reach one useful project inspection with the installed plugin.

  1. Check that the bundled PIO Agent MCP server responds. If it cannot start, report the launch error and verify that Node.js is available; do not silently replace the packaged runtime with a source checkout.
  2. Identify the intended PlatformIO project from the active workspace. If there are several plausible platformio.ini files, let the user choose the project before calling project-scoped tools.
  3. Call get_project_context with the explicit project directory. Summarize declared environments, source and dependency state, build cache, connected devices, and the next useful step. Use list_devices only when current device detail is needed.
  4. If PlatformIO Core is missing, explain the prerequisite and the existing installation instructions. Do not install packages or toolchains without a user request.
  5. Offer a build or dashboard inspection as the next step. A first-run check must not flash, erase, open the browser, or approve hardware operations automatically.

When a native Codex panel is supported, the platformio-dashboard skill can open it. Otherwise use the documented browser or headless route and state which surface is available.

Changes

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.

get-started is a skill published in the GitHub repository jl-codes/platformio-mcp (54 stars, last pushed 16d ago), licensed MIT. It adds 52 tokens to every session and 308 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-02.
