# Coding Agent (background-first)
|
|
|
|
Use **bash background mode** for coding agents. Full programmatic control, no tmux needed.
|
|
|
|
## The Pattern: workdir + background
|
|
|
|
```bash
|
|
# Start agent in target directory ("little box" - only sees relevant files)
|
|
bash workdir:~/project/folder background:true command:"<agent command>"
|
|
# Returns sessionId for tracking
|
|
|
|
# Monitor progress
|
|
process action:log sessionId:XXX
|
|
|
|
# Check if done
|
|
process action:poll sessionId:XXX
|
|
|
|
# Send input (if agent asks a question)
|
|
process action:write sessionId:XXX data:"y"
|
|
|
|
# Kill if needed
|
|
process action:kill sessionId:XXX
|
|
```
|
|
|
|
**Why workdir matters:** Agent wakes up in a focused directory, doesn't wander off reading unrelated files (like your soul.md 😅).

## Codex CLI
|
|
|
|
**Model:** `gpt-5.2-codex` is the default (set in ~/.codex/config.toml)
|
|
|
|
**Reasoning effort:** Choose based on task complexity:
|
|
- `medium` — most tasks (default)
|
|
- `high` — complex/architectural tasks
|
|
|
|
### Building/Creating (use --full-auto)
|
|
```bash
|
|
bash workdir:~/project background:true command:"codex exec --full-auto \"Build a snake game with dark theme\""
|
|
```
|
|
|
|
### Reviewing (vanilla, no flags needed)
|
|
```bash
|
|
bash workdir:~/project background:true command:"codex exec \"Review PR #115. Run git diff origin/main...origin/pr/115 to see changes.\""
|
|
```
|
|
|
|
### Running Multiple Codex Processes
|
|
You can run many Codex processes in parallel! Each gets its own session:
|
|
```bash
|
|
# Start multiple reviews
|
|
bash workdir:~/project background:true command:"codex exec \"Review PR #1\""
|
|
bash workdir:~/project background:true command:"codex exec \"Review PR #2\""
|
|
bash workdir:~/project background:true command:"codex exec \"Review PR #3\""
|
|
|
|
# Check all running
|
|
process action:list
|
|
```
|
|
|
|
### PR Review Tips
|
|
- Fetch PR refs first: `git fetch origin '+refs/pull/*/head:refs/remotes/origin/pr/*'`
|
|
- Tell Codex to use: `git diff origin/main...origin/pr/XX`
|
|
- Don't let it checkout branches (conflicts with parallel reviews)

## Claude Code
|
|
|
|
```bash
|
|
bash workdir:~/project background:true command:"claude \"Your task\""
|
|
```
|
|
|
|
---
|
|
|
|
## OpenCode
|
|
|
|
```bash
|
|
bash workdir:~/project background:true command:"opencode run \"Your task\""
|
|
```
|
|

## ⚠️ Rules
|
|
|
|
1. **Respect tool choice** — if user asks for Codex, use Codex. NEVER offer to build it yourself!
|
|
2. **Be patient** — don't kill sessions because they're "slow"
|
|
3. **Monitor with process:log** — check progress without interfering
|
|
4. **--full-auto for building** — auto-approves changes
|
|
5. **vanilla for reviewing** — no special flags needed
