-## Sub-Agent Settings
-When spawning sub-agents for this project, use generous timeouts. Estimate per task — no fixed limits. Use `runTimeoutSeconds` proportional to complexity (e.g., 300 for docs, 3600+ for large multi-file implementations). Don't let timeouts cut work short.

+## Development Workflow — Claude Code
+
+**For all coding tasks, use Claude Code CLI instead of sub-agents.** Claude Code can iterate (edit → build → see errors → fix), unlike one-shot sub-agents.
+
+**Wrapper script:** `/home/openclaw/.openclaw/workspace/bin/claude-code`
+- Auto-injects Anthropic API key from OpenClaw's auth config
+- Adds Go to PATH
+
+**How to run a coding task:**
+```bash
+cd /home/openclaw/.openclaw/workspace/projects/iso-bot
+/home/openclaw/.openclaw/workspace/bin/claude-code -p "your task description here" --allowedTools "Edit,Write,Bash" --max-turns 50
+```
+
+**Use `exec` with `pty=true`** for interactive Claude Code sessions.
+
+**Project has `CLAUDE.md`** at repo root with full project context.
+
+**When to use what:**
+- **Claude Code** → all coding tasks (features, fixes, refactors)
+- **Sub-agents (`sessions_spawn`)** → research, analysis, non-coding tasks
+- **Direct edits** → small single-file changes
+
+## Sub-Agent Settings (for non-coding tasks)
+When spawning sub-agents for research/analysis, use generous timeouts. Estimate per task.
