GPT (via ocw)

Long-context coding. Best for: large refactors, feature implementation.

Prompt Guidelines

GPT strictly follows instructions. Provide as much high-level design context as possible:

• Architecture decisions, data flow, component responsibilities
• Constraints, edge cases, expected behaviors

Avoid:

• Contradictory requirements (GPT will struggle to reconcile conflicts)
• Code snippets — GPT writes code well on its own; use tokens for design info instead

Create Session (with worktree for code edits)

ocw new gpt --worktree

Returns:

• Line 1: 6-char hash
• Line 2: worktree path (e.g., /path/to/ocw-abc123)

The worktree is an isolated git branch. Work there freely.

Create Session (read-only, no worktree)

ocw new gpt

Chat

ocw chat <hash> << 'EOF'
your prompt
EOF

Chat with File

ocw chat <hash> -f /path/to/spec.md << 'EOF'
implement based on this
EOF

Worktree Workflow

1. ocw new gpt --worktree → get hash + path
2. Work in worktree: cd /path/to/ocw-{hash}
3. Edit, commit, push as needed
4. When done: git worktree remove /path/to/ocw-{hash}
