javimosch Coding Agent (background-first)
Use bash background mode for non-interactive coding work. For interactive coding sessions, use the tmux skill (always, except very simple one-shot prompts).
The Pattern: workdir + background
# Create temp space for chats/scratch work
SCRATCH=$(mktemp -d)
# Start agent in target directory ("little box" - only sees relevant files)
bash workdir:$SCRATCH background:true command:"<agent command>"
# Or for project work:
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)
Building/Creating (use --full-auto or --yolo)
# --full-auto: sandboxed but auto-approves in workspace
bash workdir:~/project background:true command:"codex exec --full-auto \"Build a snake game with dark theme\""
# --yolo: NO sandbox, NO approvals (fastest, most dangerous)
bash workdir:~/project background:true command:"codex --yolo \"Build a snake game with dark theme\""
# Note: --yolo is a shortcut for --dangerously-bypass-approvals-and-sandbox
Reviewing PRs (vanilla, no flags)
⚠️ CRITICAL: Never review PRs in Clawdbot's own project folder!
- Either use the project where the PR is submitted (if it's NOT ~/Projects/clawdbot)
- Or clone to a temp folder first
# Option 1: Review in the actual project (if NOT clawdbot)
bash workdir:~/Projects/some-other-repo background:true command:"codex review --base main"
# Option 2: Clone to temp folder for safe review (REQUIRED for clawdbot PRs!)
REVIEW_DIR=$(mktemp -d)
git clone https://github.com/clawdbot/clawdbot.git $REVIEW_DIR
cd $REVIEW_DIR && gh pr checkout 130
bash workdir:$REVIEW_DIR background:true command:"codex review --base origin/main"
# Clean up after: rm -rf $REVIEW_DIR
# Option 3: Use git worktree (keeps main intact)
git worktree add /tmp/pr-130-review pr-130-branch
bash workdir:/tmp/pr-130-review background:true command:"codex review --base main"
Why? Checking out branches in the running Clawdbot repo can break the live instance!
Batch PR Reviews (parallel army!)
# Fetch all PR refs first
git fetch origin '+refs/pull/*/head:refs/remotes/origin/pr/*'
# Deploy the army - one Codex per PR!
bash workdir:~/project background:true command:"codex exec \"Review PR #86. git diff origin/main...origin/pr/86\""
bash workdir:~/project background:true command:"codex exec \"Review PR #87. git diff origin/main...origin/pr/87\""
bash workdir:~/project background:true command:"codex exec \"Review PR #95. git diff origin/main...origin/pr/95\""
# ... repeat for all PRs
# Monitor all
process action:list
# Get results and post to GitHub
process action:log sessionId:XXX
gh pr comment <PR#> --body "<review content>"
Tips for PR Reviews
- Fetch refs first:
git fetch origin '+refs/pull/*/head:refs/remotes/origin/pr/*' - Use git diff: Tell Codex to use
git diff origin/main...origin/pr/XX - Don't checkout: Multiple parallel reviews = don't let them change branches
- Post results: Use
gh pr commentto post reviews to GitHub
Claude Code
bash workdir:~/project background:true command:"claude \"Your task\""
OpenCode
bash workdir:~/project background:true command:"opencode run \"Your task\""
Pi Coding Agent
# Install: npm install -g @mariozechner/pi-coding-agent
bash workdir:~/project background:true command:"pi \"Your task\""
Pi flags (common)
--print/-p: non-interactive; runs prompt and exits.--provider <name>: pick provider (default: google).--model <id>: pick model (default: gemini-2.5-flash).--api-key <key>: override API key (defaults to env vars).
Examples:
# Set provider + model, non-interactive
bash workdir:~/project background:true command:"pi --provider openai --model gpt-4o-mini -p \"Summarize src/\""
tmux (interactive sessions)
Use the tmux skill for interactive coding sessions (always, except very simple one-shot prompts). Prefer bash background mode for non-interactive runs.
Parallel Issue Fixing with git worktrees + tmux
For fixing multiple issues in parallel, use git worktrees (isolated branches) + tmux sessions:
# 1. Clone repo to temp location
cd /tmp && git clone git@github.com:user/repo.git repo-worktrees
cd repo-worktrees
# 2. Create worktrees for each issue (isolated branches!)
git worktree add -b fix/issue-78 /tmp/issue-78 main
git worktree add -b fix/issue-99 /tmp/issue-99 main
# 3. Set up tmux sessions
SOCKET="${TMPDIR:-/tmp}/codex-fixes.sock"
tmux -S "$SOCKET" new-session -d -s fix-78
tmux -S "$SOCKET" new-session -d -s fix-99
# 4. Launch Codex in each (after pnpm install!)
tmux -S "$SOCKET" send-keys -t fix-78 "cd /tmp/issue-78 && pnpm install && codex --yolo 'Fix issue #78: <description>. Commit and push.'" Enter
tmux -S "$SOCKET" send-keys -t fix-99 "cd /tmp/issue-99 && pnpm install && codex --yolo 'Fix issue #99: <description>. Commit and push.'" Enter
# 5. Monitor progress
tmux -S "$SOCKET" capture-pane -p -t fix-78 -S -30
tmux -S "$SOCKET" capture-pane -p -t fix-99 -S -30
# 6. Check if done (prompt returned)
tmux -S "$SOCKET" capture-pane -p -t fix-78 -S -3 | grep -q "❯" && echo "Done!"
# 7. Create PRs after fixes
cd /tmp/issue-78 && git push -u origin fix/issue-78
gh pr create --repo user/repo --head fix/issue-78 --title "fix: ..." --body "..."
# 8. Cleanup
tmux -S "$SOCKET" kill-server
git worktree remove /tmp/issue-78
git worktree remove /tmp/issue-99
Why worktrees? Each Codex works in isolated branch, no conflicts. Can run 5+ parallel fixes!
Why tmux over bash background? Codex is interactive — needs TTY for proper output. tmux provides persistent sessions with full history capture.
⚠️ Rules
- Respect tool choice — if user asks for Codex, use Codex. NEVER offer to build it yourself!
- Be patient — don't kill sessions because they're "slow"
- Monitor with process:log — check progress without interfering
- --full-auto for building — auto-approves changes
- vanilla for reviewing — no special flags needed
- Parallel is OK — run many Codex processes at once for batch work
- NEVER start Codex in ~/clawd/ — it'll read your soul docs and get weird ideas about the org chart! Use the target project dir or /tmp for blank slate chats
- NEVER checkout branches in ~/Projects/clawdbot/ — that's the LIVE Clawdbot instance! Clone to /tmp or use git worktree for PR reviews

1. [Test step] - Output: `[result]`
2. [Test step] - Result: [result]
**Files tested:**
- [Detail]
- [Edge cases]
## Session logs (implementation)
- [What was researched]
- [What was discovered]
- [Time spent]
## Implementation details
**New files:**
- `path/file.ts` - [description]
