Install Robot Python Projects

skills CLI
$ npx skills add Opentrons/opentrons --skill robot-python-projects -a claude-code

Project install by default; add -g for ~/.claude/skills/.

GitHub CLI
$ gh skill install Opentrons/opentrons robot-python-projects --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/Opentrons/opentrons.git skills-src && mkdir -p .claude/skills && cp -r skills-src/.cursor/skills/robot-python-projects .claude/skills/robot-python-projects && rm -rf skills-src

Use ~/.claude/skills/ instead of .claude/skills for a personal install. The folder must contain SKILL.md.

What it does

Robot Python Projects is an agent skill from Opentrons/opentrons. Guidelines for robot Python projects — api/, robot-server/, hardware/, auth-server/, shared-data/, server-utils/, system-server/, update-server/, usb-bridge/. Use when working with Python files in these directories or their pyproject.toml files.

Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Linting and formatting. It works with Python. The repository describes itself as: Software for writing protocols and running them on the Opentrons Flex and Opentrons OT-2. The licence is Apache-2.0.

When your agent uses it

  • Working with Python files in these directories
  • Their pyproject.toml files

Example prompts

  • “Use the robot-python-projects skill to guideline for robot Python projects — api/, robot-server/, hardware/, auth-server/, shared-data/…”
  • “/robot-python-projects”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit a14fef9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • make
    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Robot Python Projects loads about 929 tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 278 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~929

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Robot Python Projects

The following directories contain the robot Python projects — packages that run on or support Opentrons robots:

ProjectDirectoryDescription
opentronsapi/Core Opentrons Python API for protocol execution
robot-serverrobot-server/HTTP API server that runs on the robot
opentrons-hardwarehardware/Low-level hardware control and CAN bus communication
auth-serverauth-server/Authentication server for Flex
opentrons-shared-datashared-data/Shared data definitions (labware, pipettes, modules)
server-utilsserver-utils/Common utilities for Python servers
system-serversystem-server/System-level server for robot management
otupdateupdate-server/Server for software and firmware updates
ot3usbusb-bridge/USB bridge daemon for Flex

Common Patterns

  • Build system: pyproject.toml with hatchling (hatchling==1.27.0)
  • Dependency management: uv with uv.lock files (not pipenv or poetry)
  • Python version: 3.12 (set via UV_PYTHON = 3.12 in scripts/python-uv.mk)
  • Testing: pytest 9+ with config in [tool.pytest] section of pyproject.toml
  • Linting: ruff (replaces flake8 + isort) with config in [tool.ruff] sections of pyproject.toml
  • Type checking: mypy with config in [tool.mypy] section of pyproject.toml (not mypy.ini)
  • Shared Make includes: all Makefiles include ../scripts/python-uv.mk which provides common targets

Running Tests

Prefer running tests scoped to the project where your changes are:

bash
# From the project directory
cd api && make test

# Or from the monorepo root
make -C api test

Each project has a Makefile with a test target. The exception is shared-data, which uses test-py:

bash
make -C shared-data test-py

Checking Types and Linting

Each project has a Makefile with a lint target (runs ruff check + mypy). shared-data uses lint-py:

bash
make -C api lint
make -C shared-data lint-py

Formatting

Each project has a Makefile with a format target (runs ruff format + isort fix). shared-data uses format-py:

bash
make -C api format
make -C shared-data format-py

Setup and Teardown

Each project has setup and teardown targets. Setup runs uv sync --frozen --group dev --python 3.12. shared-data uses setup-py and teardown-py:

bash
make -C api setup
make -C shared-data setup-py

Or from the monorepo root for all robot Python projects at once:

bash
make setup-py      # setup all
make teardown-py   # teardown all

Dependency Management

bash
cd api  # or any robot Python project

uv add <package>              # add production dependency
uv add --group dev <package>  # add dev dependency
uv remove <package>           # remove dependency
uv lock                       # re-resolve after manual pyproject.toml edits

After changing dependencies, commit both pyproject.toml and uv.lock.
