## What it does

The skill helps build laboratory automation protocols with PyLabRobot 0.2.2. It structures resource trees for tip racks, plates, and reservoirs while checking liquid volumes. All validation runs offline. Operations execute via `LiquidHandlerChatterboxBackend`, which prints planned steps without connecting to physical ports.

Bundled scripts require Python 3.11+ and read bounded local files. The `validate_manifest.py` script validates protocol JSON files, while `check_deck_geometry.py` performs static bounding-box checks on deck layouts. Liquid transfers, well capacities, and tip usage are calculated from CSV files via `plan_transfers.py`.

Direct commands to hardware like Hamilton STAR, Tecan EVO, or Opentrons OT-2 are blocked. Software trackers provide bookkeeping only. They cannot detect physical liquid. If an error occurs, rolling back memory does not reverse liquid movement on the deck. A trained operator must confirm deck layout and calibration before live runs.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add K-Dense-AI/scientific-agent-skills --skill pylabrobot -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/pylabrobot/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/pylabrobot/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add K-Dense-AI/scientific-agent-skills --skill pylabrobot -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/pylabrobot/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add K-Dense-AI/scientific-agent-skills --skill pylabrobot -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/pylabrobot/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install K-Dense-AI/scientific-agent-skills pylabrobot
```

2. **Manually: put the files in place**
- File: `.github/skills/pylabrobot/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add K-Dense-AI/scientific-agent-skills --skill pylabrobot -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/K-Dense-AI/scientific-agent-skills --path skills/pylabrobot
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/pylabrobot/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add K-Dense-AI/scientific-agent-skills --skill pylabrobot -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/K-Dense-AI/scientific-agent-skills/tree/HEAD/skills/pylabrobot/SKILL.md

## When to use it
- simulate liquid handling transfers without physical robot access
- validate deck coordinate layouts and labware boundaries from JSON
- calculate dead volumes, tip capacities, and channel mappings from CSV
- structure offline protocol code for Hamilton STAR or Opentrons OT-2

## Example prompts
- Validate the deck layout in tests/pylabrobot/fixtures/protocol_manifest.json
- Generate an offline liquid handling plan from transfers.csv and the manifest
- Write an asynchronous PyLabRobot protocol using LiquidHandlerChatterboxBackend

# PyLabRobot

Use PyLabRobot's hardware-agnostic frontends, resource tree, trackers, and
device-specific backends to develop laboratory automation. Default to local
manifest validation, bookkeeping, and the software-only chatterbox backend.

## Verified snapshot

- PyPI stable: **`PyLabRobot==0.2.2`**, released **2026-07-30**.
- Upstream requirement: **Python >=3.9**; runtime checks here used **Python 3.13**.
- Hosted `/stable/` pages mix 0.2.1 API pages with development documentation.
  GitHub has no `v0.2.2` tag and its changelog has no 0.2.2 section. Use the
  released wheel/source distribution for the tested contract, not the URL label.
- Released liquid-handler backends include `STARBackend`, `VantageBackend`,
  `EVOBackend`, `OpentronsOT2Backend`, and the software-only
  `LiquidHandlerChatterboxBackend`.
- MicroSpin and `Plate.stacking_z_height` **are present in 0.2.2**, despite
  being listed under `Unreleased` in the current changelog. Newer development
  APIs, including the `track=` Hamilton deck keyword, are not this release.
- See the [release and transport review](references/review.md) for source
  hashes, tested behavior, and the known OT-2 cancellation mismatch.

## Non-negotiable hardware boundary

Never connect to, initialize, home, move, heat, shake, spin, pump, open/close,
or otherwise command physical equipment automatically. Do not turn a simulation
plan into a live backend merely by changing an environment variable, config
value, or import.

Before any separately authorized live run, require a trained human to:

1. Explicitly confirm the exact backend, device identity, firmware, transport,
   deck, and protocol revision.
2. Reconcile the physical deck against the resource tree, including carriers,
   adapters, lids, plates, tip racks, waste, labware orientation, barcodes, and
   every occupied coordinate.
3. Verify calibration, teaching, motion envelopes, collision risks, gripper or
