uio-ai 0.1.2rc2

Provider-agnostic AI agent/skill/prompt runner

uio

Just as Linux UIO lets kernel device drivers export their interfaces directly to userspace — eliminating the need for a full kernel module per device — uio lets AI agent definitions (plain markdown files) export their capabilities directly to a CLI, eliminating the need for a custom integration per project.

uio is a lightweight, provider-agnostic framework for defining and running AI agents, skills, and prompts. Definitions live as markdown files with YAML frontmatter. The uio CLI discovers and executes them against any supported LLM provider.

Key concepts

Concept	What it is
Agent	A multi-turn agentic loop that can execute shell commands and call MCP tools
Skill	A reusable module invoked by agents to perform a focused, composable task
Prompt	A single-shot LLM instruction for one well-defined workflow

Documentation

Full documentation lives in docs/ — covering installation, core concepts, a step-by-step quickstart, CLI reference, configuration, providers, MCP integration, the chat REPL, cost ledger, registry, writing definitions, package internals, and GitHub App identity agents.

See Use Cases for end-to-end worked examples.

Quickstart

pip install uio-ai

# Scaffold .uio/ and install bundled examples
uio init --examples

# Run one of the bundled examples
uio skill run summarise "Your text here"
uio agent run repo-health

# Interactive streaming chat
uio chat

# View token spend
uio cost

Definitions live in .uio/:

my-project/
└── .uio/
    ├── agents/   my-agent.agent.md
    ├── skills/   my-skill.skill.md
    └── prompts/  my-prompt.prompt.md

See Writing Definitions for the full file format and authoring guide.

GitHub App identities

uio supports dedicated GitHub App identities for agents that act on GitHub — separate non-human service accounts for planning, coding, and reviewing work:

Identity	Agent	Operations
AI Planner	github-planner	Create issues · Comment on issues and PRs · Summarize milestones
AI Coder	github-coder	Create branches · Commit code · Open pull requests
AI Reviewer	github-reviewer	Read diffs · Post structured review comments

Declare the identity in your agent's frontmatter:

---
name: my-github-agent
github-identity: coder   # planner | coder | reviewer
tools: [terminal, github]
---

uio obtains a short-lived GitHub App installation token before the agent loop starts and sets GH_TOKEN — both the gh CLI and GitHub MCP server pick it up automatically. All three agents are available in uio-registry.

See Governance and Provisioning guides for setup.

Registry

Discover and install community definitions from remote registries — Git repos with a registry.yaml manifest. No central server required.

# Add a registry to uio.toml:
# [[registries]]
# name = "official"
# url  = "https://github.com/jomkz/uio-registry"
# ref  = "main"

uio registry list                   # show configured registries
uio registry search summarise       # search by name, description, or tag
uio registry install summarise      # copy definition into .uio/
uio registry install repo-health --pin  # install and print a pinnable SHA
uio registry update                 # refresh cached manifests

Installed definitions are plain local files — no live runtime dependency on the registry.

Providers

Auto-routes across available providers in order: Gemini → OpenAI → Ollama. Override with --provider or uio.toml.

Provider	Large model	Small model
gemini	gemini-2.5-flash	gemini-2.0-flash-lite
openai	gpt-4o	gpt-4o-mini
ollama	llama3.1:8b	llama3.1:8b

Container image

# bash/zsh
docker run --rm \
  -e GEMINI_API_KEY=your-key \
  -e GITHUB_PERSONAL_ACCESS_TOKEN=ghp_... \
  -v $(pwd):/workspace \
  ghcr.io/jomkz/uio agent run repo-health

# PowerShell (Windows) — use ${PWD} instead of $(pwd)
docker run --rm `
  -e GEMINI_API_KEY=your-key `
  -e GITHUB_PERSONAL_ACCESS_TOKEN=ghp_... `
  -v ${PWD}:/workspace `
  ghcr.io/jomkz/uio agent run repo-health

# Cross-platform — docker compose avoids the $(pwd) issue entirely
docker compose run --rm uio agent run repo-health

The image includes Node.js and pre-warmed MCP servers (@github/github-mcp-server, server-filesystem, server-fetch, server-memory). A docker-compose.yml for local Ollama use is included in the repo. See Container image for full details.
