Feature request: First-class oh-my-pi (OMP) support via native extension

[dlivxpr]

Summary

Superpowers now has first-class support for the Pi coding agent (closed #435, implemented in #1499), and it can already be loaded in oh-my-pi through the Claude-plugin compatibility path (see this comment). However, there is no dedicated, native .omp/* integration that allows oh-my-pi to discover and bootstrap Superpowers from a direct checkout of this repository.

I would like to request a native oh-my-pi extension so that users can install Superpowers directly without needing to register a Claude plugin registry entry.

Background

• oh-my-pi (can1357/oh-my-pi) is a feature-rich fork of the original Pi coding agent. While it maintains compatibility with the Pi extension model, its SDK is published as @oh-my-pi/pi-coding-agent and it has its own built-in tool set (e.g., read, write, edit, bash, grep, glob, task, irc, etc.).
• The current .pi/extensions/superpowers.ts imports from @earendil-works/pi-coding-agent (the original Pi SDK) and relies on resources_discover to register the skills/ directory.
• oh-my-pi does not currently invoke resources_discover from AgentSession (per its own extension docs), so the skills may not be auto-discovered by a raw checkout.

Motivation

1. Direct install experience: Users expect to run something like omp install git:github.com/obra/superpowers or load the checkout directly, similar to how pi install works for the original Pi.
2. Better tool mapping: Native support can map Superpowers workflows to oh-my-pi's built-in subagent/task tools (task, irc, etc.) rather than treating them as optional companion packages.
3. Clearer documentation: A dedicated README.omp.md and .omp/INSTALL.md would reduce confusion between Pi and oh-my-pi.

Proposed scope

• Add .omp/extensions/superpowers.ts (or equivalent) targeting @oh-my-pi/pi-coding-agent.
• Register the skills/ directory using oh-my-pi's native skill discovery mechanism.
• Inject the using-superpowers bootstrap at session start and after compaction, mirroring the current Pi extension.
• Provide tool-mapping guidance for oh-my-pi's built-in tools.
• Add documentation: docs/README.omp.md and/or .omp/INSTALL.md.
• Add smoke tests for direct checkout discovery in an isolated oh-my-pi environment.

Non-goals

• Full 1:1 parity with Claude Code or the original Pi harness is not expected.
• This request is specifically about native direct-checkout support, not about replacing the existing Claude-plugin compatibility path.
