The missing manual

Drive omp like you built it.

The beginner guide to oh-my-pi (omp): cheat sheets, tips and tricks, sane configs, and the traps that cost you an afternoon.

omp is a terminal coding agent: one TUI (plus headless modes) that drives Claude, GPT, Gemini and local models against your codebase, with LSP, a debugger, subagents, and a Rust-fast tool layer built in. It is powerful and dense. This repo is the on-ramp.

Not an official publication. omp moves fast and defaults change. Everything here was verified on a live install of the release recorded in data/version.txt; a weekly job re-checks every new release and files an issue when anything documented here drifts. Run omp config list to see what your install actually does.

Start here

You want	Read
Install and a first productive session	Getting started
Every key, command, flag, and path on one page	Cheat sheet
Understand and tune the config (and not get burned)	Settings
Habits that make omp feel unfair	Tips and tricks
Subagents, parallel work, the advisor	Multi-agent
The mistakes everyone makes once	Traps

The 5-minute version

# install (macOS / Linux)
curl -fsSL https://omp.sh/install | sh

# first session, in a repo you know
cd your-repo
omp

Then, in order:

1. Run omp config get tools.approvalMode. It says yolo: every tool call auto-approves, shell included. Decide deliberately whether you want that on this machine (see Settings).
2. Type /plan before your first non-trivial task. The agent goes read-only and writes a plan file; read it before approving.
3. When the agent does something annoying, type /omfg. It forges a permanent correction rule from your complaint.
4. Press Shift+Tab to change the thinking level, Ctrl+P to cycle models.
5. Read the diff it produced, not the conversation.

Sources

• The oh-my-pi repository: docs, settings schema, command registry.
• A live install: omp --help, omp config list, and real usage data.
• Automated drift tracking: a weekly CI job installs the latest omp, snapshots its settings schema and CLI surface into data/, and opens an issue when anything documented here changes. See How this stays current.

How this stays current

omp ships fast, and stale guides are worse than no guides. This repo tracks upstream automatically:

• data/ holds machine-readable snapshots of the omp surface: version.txt, settings.json (every key, type, default), subcommands.txt, flags.txt.

• A weekly GitHub Action installs the latest omp in a clean environment, regenerates the snapshots, commits the diff, and opens an issue listing exactly which settings, defaults, commands, or flags changed. Each issue is the review queue for updating the prose.

• No version numbers are hardcoded in the prose. data/version.txt is the single source of truth for what the guide was last verified against, and the issue queue is the list of what moved since.

• The update itself is agent-driven: .omp/commands/update-docs.md is a versioned brief that compares the guide against a live install and rewrites every drifted page. In omp, run /update-docs from the repo root; in any other coding agent, paste the file as the prompt.

Regenerate snapshots locally anytime: sh scripts/snapshot.sh.

Contributing

PRs welcome. One rule: every stated default or behavior must be checkable against the omp source or a live install, and the version it was checked against stays in the text.
