Oh My Pi integration

Terminal agent with LSP, subagents, and plan mode. Binary is omp.

1
Install it
Homebrew, Bun, Nix, and a PowerShell installer work too — the repo lists all of them. The binary is called omp, not oh-my-pi.
```
curl -fsSL https://omp.sh/install | sh
```
Create a key
Mint one on the API keys page and name it omp, so it can be revoked on its own if the machine it lives on is lost.
3
Export the key
The config below names the variable, not the secret, so models.yml stays safe to sync between machines.
```
export XMR4AI_API_KEY="xmr4ai_live_..."
```

Declare the provider

Create ~/.omp/agent/models.yml. apiKey is the name of the environment variable to read, and authHeader: true is what sends it as Authorization: Bearer. Models are listed explicitly — omp cannot enumerate a custom provider’s catalogue.

providers:
  xmr4ai:
    baseUrl: https://xmr4ai.com/api/v1
    api: openai-completions
    apiKey: XMR4AI_API_KEY
    authHeader: true
    models:
      - id: anthropic/claude-sonnet-4
        name: Claude Sonnet 4
        contextWindow: 200000
        maxTokens: 64000
        input: [text, image]
      - id: openai/gpt-4.1-mini
        name: GPT-4.1 Mini
        contextWindow: 1000000
        maxTokens: 32000
        input: [text, image]

5
Run it
Models are addressed as provider/model-id. Since the ids here already contain a slash, the argument carries two — xmr4ai is the provider, the rest is the model. /model switches mid-session.
```
omp --model xmr4ai/anthropic/claude-sonnet-4
```
6
Make it the default (optional)
Add this to ~/.omp/agent/config.yml so omp on its own starts on this model instead of needing the flag every time.
```
modelRoles:
  default: xmr4ai/anthropic/claude-sonnet-4
```
