oh-my-agent: The Multi-Agent Harness That Checks the Work

한국어 | 中文 | Português | 日本語 | Français | Español | Nederlands | Polski | Русский | Deutsch | Tiếng Việt | ภาษาไทย

Agents narrate success. oh-my-agent checks the artifacts.

Spawning parallel agents is the easy part. The hard part is knowing whether they actually did the work. "Tests pass, all criteria met" costs an agent nothing to say, and nothing inside that same session can contradict it.

oh-my-agent makes the claim falsifiable. A Stop hook refuses to end your session until your project's own typecheck / test / lint script exits 0. A gate command decides whether a workflow really ran by looking for the artifacts it must have left behind — and its JSON verdict, not the agent's summary, is the result. An independent judge with a fresh context re-verifies every criterion each round, including the ones that already passed. Every gate decision lands on an append-only event log you can read after the fact. Then it runs that same discipline across a dozen agent runtimes from one portable .agents/ directory.

Quick Start

The install scripts below auto-install bun, uv, and serena if they're missing.

# macOS / Linux — auto-installs bun, uv & serena if missing
curl -fsSL https://raw.githubusercontent.com/first-fluke/oh-my-agent/main/cli/install.sh | bash

# Windows (PowerShell) — auto-installs bun, uv & serena if missing
irm https://raw.githubusercontent.com/first-fluke/oh-my-agent/main/cli/install.ps1 | iex

# Or manual (any OS, requires bun + uv + serena)
bunx oh-my-agent@latest

Not to be confused with oma-observability's APM (Application Performance Monitoring).

# All skills, deployed to every detected runtime
# (.claude, .cursor, .codex, .opencode, .github, .agents)
apm install first-fluke/oh-my-agent

# A single skill
apm install first-fluke/oh-my-agent/.agents/skills/oma-frontend

APM ships skills only. For workflows, rules, oma-config.yaml, keyword-detection hooks, and the oma agent spawn CLI, use bunx oh-my-agent@latest. Pick one distribution per project to avoid drift.

Works With Every Agent

Verification is worth little if it's locked to one vendor. oh-my-agent keeps .agents/ as the single source of truth and projects it into each runtime's native layout, so every supported tool shares the same skills, workflows, rules, and gates — and switching vendors is a config change, not a migration.

Your Engineering Team

Instead of one AI doing everything (and getting confused halfway through), oh-my-agent splits work across specialized agents. Each one knows its domain deeply, has its own tools and checklists, and stays in its lane.
