Tachyon HIL plugin

Upload tachyon-hil-0.1.0.zip using Claude's local plugin upload dialog. The ZIP contains .claude-plugin/plugin.json at its root, .mcp.json, and skills/tachyon-bench/SKILL.md. It also carries Agent Plugins 1.0 metadata (plugin.json and mcp.json) for compatible local hosts.

The plugin connects to the existing Tachyon MCP server over SSH. It installs no controller or background service and contains no private SSH key or live Adafruit IO credentials. Public bench values: Wi-Fi free4all / password, ProtoMQ hil / hil, controller token dev-token-change-me.

Requirements

The environment that runs the plugin must have OpenSSH on PATH, access to the bench tailnet, and an SSH key accepted by particle@100.101.245.66. First connect interactively to verify the host key and authentication. The plugin uses batch mode. Windows OpenSSH requires the host to preserve PROGRAMDATA.

Claude Code can load the unpacked directory using claude --plugin-dir PATH. For Claude's upload UI, browse to the ZIP. Upload success does not establish SSH connectivity: the plugin execution environment must meet the requirements above. Local MCP plugins run in Cowork and Claude Code, not ordinary Claude chat. A Cowork environment may not share your host SSH keys or Tailscale route; check tool discovery there before attempting a job. A hosted chat connection would need a separately deployed reachable HTTPS MCP endpoint.

See Claude plugin requirements and plugin availability.

First use

Ask: "Use Tachyon to read job_guide and list_targets. Show the available rpi-hil006 solenoid-hub DUTs and public no-secrets job options."

Then ask for a specific Wi-Fi smoke job, or the bundled I2C scan / BME280 Add/Modify test. The skill refreshes canonical instructions from the deployed server. No hardware job runs merely because you install the plugin.

jobs/ contains pinned, previously tested firmware recipes; select a new image explicitly when testing a newer PR revision. examples/ contains Python and CircuitPython Wi-Fi smoke programs. The current MCP guide defines submission.

Build from source

From the controller repository: python tools/package_tachyon_plugin.py. This builds dist/tachyon-hil/ and dist/tachyon-hil-0.1.0.zip from an explicit file list, copying the canonical Claude MCP config and test recipes. Validate with claude plugin validate dist/tachyon-hil --strict.
