+# codes doctor - System Diagnostics
+
+The `codes doctor` command runs comprehensive system diagnostics to verify your Claude Code environment is properly configured and healthy.
+
+## Usage
+
+```bash
+codes doctor
+```
+
+## What It Checks
+
+### 1. Claude CLI Installation
+- ✓ Verifies Claude CLI is in PATH
+- ✓ Displays Claude CLI version
+- ✗ Suggests installation command if missing
+
+### 2. Configuration File
+- ✓ Confirms config file exists and is valid
+- ✓ Shows number of configured API profiles
+- ✓ Displays default profile name
+- ! Warns if no profiles configured
+- ✗ Fails if config is corrupted
+
+### 3. API Connectivity
+- ✓ Tests connection to default API profile
+- ! Skips test if no profiles configured
+- ✗ Fails if API is unreachable
+
+### 4. File Permissions
+- ✓ Checks config directory (`~/.codes/`) is writable
+- ✓ Checks session directory (`~/.claude/`) is writable
+- ✗ Fails if critical directories aren't writable
+
+### 5. Agent Daemons
+- ✓ Lists all teams and agents
+- ✓ Shows running/stopped status for each agent
+- ℹ Provides command to start stopped agents
+- ! Warns if unable to check team status
+
+### 6. Disk Space
+- ℹ Shows Claude session data size
+- ℹ Shows codes data size
+- ℹ Displays disk usage percentage
+- ✓ Confirms sufficient space available
+- ! Warns if disk usage > 90% or < 1GB free
+- ✗ Fails if disk is critically full
+
+## Exit Codes
+
+- `0` - All checks passed (may have warnings)
+- `1` - One or more critical checks failed
+
+## Example Output
+

+
+## When to Use
+
+Run `codes doctor` when:
+- Setting up codes for the first time
+- Troubleshooting connection issues
+- Before opening a support ticket
+- After system updates
+- When agent daemons aren't responding
+- If session data seems corrupted
+
+## Troubleshooting
+
+### Claude CLI Not Found
+```bash
+npm install -g @anthropic-ai/claude
+```
+
+### No API Profiles
+```bash
+codes profile add
+```
+
+### Disk Space Low
+Clean up old Claude sessions:
+```bash
+# Review session data
+ls -lh ~/.claude/
+
+# Remove old sessions if needed
+rm -rf ~/.claude/sessions/old-session-id
+```
+
+### Agents Not Running
+```bash
+# Start all agents in a team
+codes agent start-all <team-name>
+
+# Or start specific agent
+codes agent start <team-name> <agent-name>
+```
