Installation
Add flowio to your agent with:
git clone https://github.com/K-Dense-AI/scientific-agent-skills ~/.claude/skills/flowioReview a skill’s source before installing it — skills can instruct your agent to run commands. This command comes from the skill’s public repository, which is the source of truth for setup steps. New to skills? Read how to install Claude Code skills.
Supported agents
Neither the skill nor its repository names a specific agent. It uses the SKILL.md format, which several agents can load — check the repository for any agent-specific requirements.

Use for low-level FCS metadata and channel inspection, NumPy event extraction, multi-dataset files, table export, and FCS 3.1 creation; use FlowKit for compensation, cytometry transforms, gating, or FlowJo workspaces.
- How do I install flowio?
- Run git clone https://github.com/K-Dense-AI/scientific-agent-skills ~/.claude/skills/flowio in your agent, then reload your skills. Review the source at https://github.com/K-Dense-AI/scientific-agent-skills before installing.
- Is flowio free to use?
- Yes. flowio is free and open source under the MIT license, so you can read, run, and adapt it within that license's terms.
- Where does flowio come from?
- flowio ships inside K-Dense-AI/scientific-agent-skills, a repository that contains 42 catalogued skills in total. The repository's 33,821 GitHub stars apply to that whole collection, not to this skill on its own.
