Codex CLI

• Non-interactive execution: codex exec (or codex e).
• JSON streaming: codex exec --json "..." outputs JSON Lines events to stdout.
• Structured output: codex exec --output-schema ./schema.json -o ./output.json "...".
• Final message is written to stdout; streaming activity goes to stderr.
• Model override: codex exec -m gpt-5.2-codex -c model_reasoning_effort=xhigh "...".

Claude Code

• Launch interactive agent: claude in the repo directory.
• Non-interactive print mode: claude -p "query" (prints response and exits).
• JSON output: claude -p "query" --output-format json.
• Schema-validated JSON: claude -p --json-schema '<schema>' "query" (print mode only).
• Model selection: claude -p --model opus "query" (alias for latest Opus).
• Claude CLI accepts a full model name via --model (example in docs uses claude-sonnet-4-5-20250929).
• Debug mode: claude --debug.

Gemini CLI

• Non-interactive prompt: gemini -p "...".
• Structured JSON output: gemini -p "..." --output-format json.
• Streaming JSON events: gemini -p "..." --output-format stream-json.

OpenCode CLI

• Non-interactive prompt: opencode run "...".
• Run flags include --model (provider/model), --agent, --format (default or json), and --attach to a running server.
