# Claude Code Dependency Fix

**Date**: 2025-10-03
**Status**: ✅ FIXED
**Version**: 1.5.3

## Problem Identified

The navam package had a **hidden dependency on Claude Code installation** that caused failures in production:

### Root Cause

**chat.py:335-350** - Agent discovery logic only worked if Claude Code was installed:

```python
# ❌ BEFORE: Only checked ~/.claude/agents/ (requires Claude Code)
user_claude_agents = Path.home() / ".claude" / "agents"
if user_claude_agents.exists():  # FAILED if Claude Code not installed
    agent_dirs.append(Path.home())
```

**The Issue:**
1. Package bundled agents in `src/navam/agents/` ✅
2. But SDK was told to look in `~/.claude/agents/` ❌
3. If Claude Code wasn't installed, `~/.claude/agents/` didn't exist
4. Package couldn't find its own bundled agents
5. Investment commands failed with "agents not found"

### User Impact

```
navam chat  # ❌ Failed without Claude Code
/invest:research-stock AAPL  # ❌ "No agents found"
```

After reinstalling Claude Code, it worked because it created `~/.claude/agents/`.

## Solution Implemented

### 1. Updated Sync Script (src/navam/sync.py)

Added `sync_agents()` function and updated `sync_investment_commands()` for consistent `.claude/` structure:

```python
def sync_agents():
    """Copy agent definitions from .claude/agents/ to src/navam/.claude/agents/"""
    source_dir = Path('.claude/agents')
    target_dir = Path('src/navam/.claude/agents')
    # Copy all 18 agent files

def sync_investment_commands():
    """Copy commands from .claude/commands/invest/ to src/navam/.claude/commands/invest/"""
    source_dir = Path('.claude/commands/invest')
    target_dir = Path('src/navam/.claude/commands/invest')
    # Copy all 8 command files
```

**Key Points:**
- ✅ **Consistent `.claude/` structure** for both agents and commands
- ✅ Does NOT move/disturb Claude Code files
- ✅ Copies to `src/navam/.claude/` subdirectories
- ✅ Preserves development structure

### 2. Fixed Agent Discovery (chat.py:334-343)

```python
# ✅ AFTER: Check package bundled agents FIRST
package_claude_dir = Path(__file__).parent / ".claude/agents"
if package_claude_dir.exists():
    # Add package directory so SDK finds bundled agents
    agent_dirs.append(Path(__file__).parent)

    # Backup: Also copy to ~/.claude/agents/
    self._ensure_user_agents_dir(package_claude_dir)

# Claude Code is now OPTIONAL
user_claude_agents = Path.home() / ".claude" / "agents"
if user_claude_agents.exists():
    agent_dirs.append(Path.home())
```

**Critical Change:**
- Line 339: `agent_dirs.append(Path(__file__).parent)`
- This tells Claude Agent SDK to look in the package directory
- Package now works WITHOUT Claude Code!

### 3. Updated Package Configuration (pyproject.toml)

```toml
"navam" = [
    ".claude/agents/*.md",           # ← Consistent .claude/ structure
    ".claude/commands/invest/*.md",  # ← Consistent .claude/ structure
    ".mcp.json"
]
```

### 4. Package Structure (Consistent .claude/ Layout)

```
src/navam/
├── .claude/                 # ← Consistent with Claude Code conventions
│   ├── agents/              # 18 agent definitions
│   │   ├── atlas-investment-strategist.md
│   │   ├── quill-equity-analyst.md
│   │   └── ... (16 more)
│   └── commands/
│       └── invest/          # 8 investment workflows
│           ├── research-stock.md
│           ├── review-portfolio.md
│           └── ... (6 more)
├── .mcp.json                # MCP configuration
└── *.py                     # Python modules
```

## Verification

### Sync Test
```bash
$ uv run python src/navam/sync.py

✅ Copied 18 agent definitions
✅ Copied 8 investment commands
✅ Package structure verified
🎯 Package will work standalone without Claude Code installation
```

### Runtime Test
```python
from navam.chat import InteractiveChat

chat = InteractiveChat()
agent_dirs = chat._get_agent_directories()

# Result: 3 directories
# 1. /path/to/navam (development .claude/agents/)
# 2. /path/to/navam/src/navam (package .claude/agents/) ← KEY FIX
# 3. ~/.claude/agents/ (optional, if Claude Code installed)
```

## Build Process

### Before Building Package

**CRITICAL:** Always run sync script before building:

```bash
# 1. Sync development files to package
uv run python src/navam/sync.py

# 2. Verify sync succeeded
ls -la src/navam/.claude/agents/  # Should show 18 agents

# 3. Build package
uv run python -m build
```

### What Gets Bundled

The package now includes **consistent `.claude/` structure**:
- ✅ 18 agent definitions in `.claude/agents/*.md`
- ✅ 8 investment commands in `.claude/commands/invest/*.md`
- ✅ MCP server configuration in `.mcp.json`
- ✅ All Python modules

**Why Consistent Structure:**
- Matches Claude Code conventions exactly
- Both agents and commands in `.claude/` subdirectories
- Makes package structure predictable and maintainable

## Key Learnings

### 1. Never Move Claude Code Files

❌ **DON'T:**
```bash
mv .claude/agents src/navam/agents  # BREAKS development!
```

✅ **DO:**
```bash
uv run python src/navam/sync.py  # Copies, doesn't move
```

### 2. Package Structure Matters

Claude Agent SDK expects `.claude/agents/` structure:
- ✅ `src/navam/.claude/agents/*.md` - SDK finds these
- ❌ `src/navam/agents/*.md` - SDK ignores these

### 3. Sync Before Build

The sync script is **ESSENTIAL** for packaging:
```bash
# Development files (DON'T touch)
.claude/
├── agents/              # 18 agents
└── commands/invest/     # 8 commands

# Package files (sync copies here with consistent structure)
src/navam/.claude/
├── agents/              # ← Bundled with package
└── commands/invest/     # ← Bundled with package
```

## Testing Checklist

Before releasing new version:

- [ ] Run `uv run python src/navam/sync.py`
- [ ] Verify 18 agents in `src/navam/.claude/agents/`
- [ ] Verify 8 commands in `src/navam/.claude/commands/invest/`
- [ ] Verify consistent `.claude/` structure in package
- [ ] Build package: `uv run python -m build`
- [ ] Test in clean environment without Claude Code
- [ ] Test `/invest:research-stock AAPL` command

## Impact

```
❌ Required Claude Code installation
❌ Failed in clean environments
❌ Production users couldn't use custom commands
```

### After Fix (v1.5.3)
```
✅ Works standalone without Claude Code
✅ Agents bundled in package
✅ Production ready
✅ Custom commands work out-of-box
```
