Overriding Context Size for Opus 4.6 on GH Copilot OpenCode

Pi Harness Approach (current)

In ~/.pi/agent/models.json, models are defined with explicit contextWindow and maxTokens fields, plus a modelOverrides block for the github-copilot provider:

"modelOverrides": {
  "claude-opus-4.6": {
    "contextWindow": 192000,

// Minimal REST call to the Codex backend API using a local OAuth token.

import fs from "fs";
import os from "os";
import path from "path";

const authFile = process.env.CODEX_AUTH_FILE || path.join(os.homedir(), ".codex", "auth.json");
const auth = JSON.parse(fs.readFileSync(authFile, "utf8"));
const token = auth.access_token || auth.tokens?.access_token;

Git Bare Repository Worktree Workflow for Claude Code

🚨 CRITICAL: Understanding My Project Structure

I use a bare Git repository approach with Git worktrees extensively. Every subdirectory in my projects represents a different git branch as a worktree.

When you see a project like /home/code/projects/my-app/:

• my-app/ = project container (NOT a working tree)
• my-app/.bare/ = actual Git repository database
• my-app/.git = pointer file directing Git commands to .bare/
