Giga Coding Agent

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 comment to 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
