What Pneuma Impl is
Pneuma Impl is a subagent published in the pandazki/pneuma-skills repository on GitHub, which has about 162 stars. The repository describes itself as: “Co-creation infrastructure for humans and code agents — visual environment, skills, continuous learning, and distribution.”
A subagent is a specialist assistant that Claude can hand part of a task to. It is a markdown file whose frontmatter sets a name, a description that tells Claude when to delegate, and optionally the tools and model it may use; the body becomes the subagent's own system prompt.
Because a subagent works in its own context, it keeps the main conversation focused: Claude can send a narrow job, such as a review or a specialised analysis, to Pneuma Impl and get back a compact result.
It is set up to use these tools: Bash, Read, Edit, Write, Grep, Glob, Skill, TaskCreate, TaskUpdate, TaskList, TaskGet. Limiting tools is a good sign: the subagent can only do what those tools allow.
How to install Pneuma Impl
Claude Code
- Download pneuma-impl.md from the repository.
- Save it to ~/.claude/agents/ to use it in every project, or to .claude/agents/ inside one project to share it through version control.
- Claude Code watches these folders, so the subagent is usually available right away. Ask Claude to use it by name, or @-mention it to make sure it runs.
Claude Cowork
- Cowork loads subagents through plugins. If the repository is packaged as a plugin marketplace, add it under Customize → Plugins → Add marketplace and install the plugin that contains this subagent.
- Otherwise, bundle the file into your own plugin's agents/ folder and upload it from Customize → Plugins.
New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.
Inside the source file
An excerpt from .claude/agents/pneuma-impl.md, shared under the repository's MIT license. Read the full file on GitHub.
Read .agents/skills/dev-workflow/references/roles/impl.md before acting. That file is the canonical role instruction shared with Codex. Read root AGENTS.md and its matching domain-rule pointers as directed there.
Apply the parent's task, checkout, acceptance criteria, and authorization. Use the tools actually available in this session. Return the evidence and result format required by the shared role; do not merely summarize the guide.
Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
