opentrons-liquid-handling-protocol-starter

opentrons-liquid-handling-protocol-starter is a skill for Claude Code, Codex from ma-compbio-lab/SkillFoundry. It costs 0 tokens per session (298 once invoked), scanned A, original, Apache-2.0.

A tool that creates a small Python program for an Opentrons liquid-handling robot and checks it with Opentrons' local simulator. It covers one plate, one tip rack, one pipette, and one transfer step.

In plain words
What is it for?
Use it to generate and simulate basic liquid-transfer protocols and inspect the resulting robot command trace.
Why use it?
It lets you catch structural problems in a robot protocol before sending anything to an OT-2 or Flex robot.

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

opentrons-liquid-handling-protocol-starter 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 1mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/run_opentrons_liquid_handling_protocol.py, tests/test_run_opentrons_liquid_handling_protocol.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Opentrons Liquid-Handling Protocol Starter

Use this skill to generate a minimal Opentrons Protocol API transfer script and verify it through the local simulator.

What it does

  • Renders a small Protocol API 2.x script with one plate, one tiprack, one pipette, and one transfer step.
  • Runs the generated script through opentrons.simulate to confirm the protocol is structurally valid.
  • Returns a compact JSON summary with the rendered file path and the simulated command trace.

When to use it

  • You need a runnable starter for Liquid-handling protocol generation.
  • You want a verified local protocol scaffold before touching a real OT-2 or Flex robot.

Example

slurm/envs/automation/bin/python skills/robotics-lab-automation-and-scientific-instrumentation/opentrons-liquid-handling-protocol-starter/scripts/run_opentrons_liquid_handling_protocol.py \
  --protocol-out scratch/opentrons/toy_protocol.py \
  --out scratch/opentrons/toy_protocol_summary.json

Verification

  • Skill-local tests: python3 -m unittest discover -s skills/robotics-lab-automation-and-scientific-instrumentation/opentrons-liquid-handling-protocol-starter/tests -p 'test_*.py'
  • Repository smoke: python3 -m unittest tests.smoke.test_phase30_empty_domain_seed_skills -v
Files

What ships with it

7 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.

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.

opentrons-liquid-handling-protocol-starter is a skill published in the GitHub repository ma-compbio-lab/SkillFoundry (43 stars, last pushed 1mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 298 tokens. 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 2026-09-03.
