# AgentOS Path Resolution Fixes - Summary

## Problem Statement

AgentOS was experiencing operational issues when run from directories other than the project root:

- ❌ Manifest files not found when running from different directories
- ❌ Web UI templates not loading from non-project directories
- ❌ Example manifests not discoverable
- ❌ Relative path handling inconsistent
- ❌ Configuration files hard to locate

## Solution Overview

Implemented a comprehensive path resolution system that allows AgentOS to work correctly from any directory while maintaining centralized data storage.

## Changes Made

### 1. New Path Resolver Module
**File**: `agentos/core/path_resolver.py`

**Purpose**: Centralized path resolution logic

**Key Functions**:
- `resolve_manifest_path()` - Find manifest files from multiple locations
- `get_project_root()` - Get AgentOS installation directory
- `get_examples_dir()` - Get examples directory
- `get_templates_dir()` - Get templates directory
- `get_static_dir()` - Get static files directory
- `find_all_manifests()` - Discover all available manifests
- `get_working_directory()` - Get current working directory
- `make_path_absolute()` - Convert relative to absolute paths

**Search Strategy**:
1. Absolute paths (if provided)
2. Current working directory
3. Home directory
4. Project root directory
5. Examples directory

### 2. Updated Configuration Module
**File**: `agentos/core/config.py`

**Changes**:
- Integrated path_resolver for YAML file discovery
- Improved error messages showing all searched locations
- Support for relative and absolute paths
- Better error reporting

**Before**:
```python
path = Path(yaml_path)
if not path.exists():
    raise FileNotFoundError(f"YAML file not found: {yaml_path}")
```

**After**:
```python
resolved_path = path_resolver.resolve_yaml_path(yaml_path)
if resolved_path is None:
    raise FileNotFoundError(
        f"YAML file not found: {yaml_path}\n"
        f"Searched in:\n"
        f"  - {Path.cwd() / yaml_path}\n"
        f"  - {Path.home() / yaml_path}\n"
        f"  - {path_resolver.get_project_root() / yaml_path}\n"
        f"  - {path_resolver.get_examples_dir() / yaml_path}"
    )
```

### 3. Enhanced CLI Command Handler
**File**: `agentos/cli/cli_cmd_basic.py`

**Changes**:
- Improved manifest path resolution
- Better error messages with search paths
- Support for both absolute and relative paths
- Fallback to current working directory

**Before**:
```python
manifest_path = Path(args.manifest)
if not manifest_path.exists():
    console.print(f"[red]❌ Manifest file not found: {args.manifest}[/red]")
```

**After**:
```python
manifest_path = Path(args.manifest).resolve()
if not manifest_path.exists():
    manifest_path = Path.cwd() / args.manifest
    if not manifest_path.exists():
        console.print(f"[red]❌ Manifest file not found: {args.manifest}[/red]")
        console.print(f"[dim]Searched in: {Path(args.manifest).resolve()}[/dim]")
```

### 4. Improved CLI Helpers
**File**: `agentos/cli/cli_helpers.py`

**Changes**:
- Integrated path_resolver module
- Better manifest path resolution
- Improved error handling
- Support for multiple search locations

### 5. Enhanced Web UI
**File**: `agentos/web/web_ui.py`

**Changes**:
- Uses path_resolver for template and static file discovery
- Automatic directory creation if needed
- Works from any directory

**Before**:
```python
project_root = Path(__file__).parent.parent.parent
template_folder = project_root / 'templates'
static_folder = project_root / 'static'
```

**After**:
```python
from agentos.core import path_resolver

template_folder = path_resolver.get_templates_dir()
static_folder = path_resolver.get_static_dir()

template_folder.mkdir(parents=True, exist_ok=True)
static_folder.mkdir(parents=True, exist_ok=True)
```

### 6. Updated Web Routes
**File**: `agentos/web/web_routes.py`

**Changes**:
- Multi-location manifest discovery
- Searches current directory, home, project root, and examples
- Deduplicates found manifests
- Better error handling

**Before**:
```python
manifests = []
for yaml_file in Path('.').glob('*.yaml'):
    manifests.append(str(yaml_file))
for yaml_file in Path('examples').glob('*.yaml'):
    manifests.append(str(yaml_file))
```

**After**:
```python
manifests = []
manifest_dirs = [
    Path.cwd(),
    Path.home(),
    Path(__file__).parent.parent.parent,
]

for manifest_dir in manifest_dirs:
    if manifest_dir.exists():
        for yaml_file in manifest_dir.glob('*.yaml'):
            manifest_str = str(yaml_file)
            if manifest_str not in manifests:
                manifests.append(manifest_str)

examples_dir = Path(__file__).parent.parent.parent / 'examples'
if examples_dir.exists():
    for yaml_file in examples_dir.glob('*.yaml'):
        manifest_str = str(yaml_file)
        if manifest_str not in manifests:
            manifests.append(manifest_str)
```

## Benefits

### ✅ Works from Any Directory
```bash
# All these now work correctly:
cd /tmp && agentos run default.yaml --task "your task"
cd ~ && agentos run default.yaml --task "your task"
cd /path/to/agentos && agentos run default.yaml --task "your task"
```

### ✅ Centralized Data Storage
- Database: Always at `~/.agentos/runtime.db`
- Logs: Always at `~/.agentos/logs/`
- Not affected by working directory

### ✅ Better Error Messages
```
❌ Manifest file not found: my-agent.yaml
Searched in:
  - /current/directory/my-agent.yaml
  - /home/user/my-agent.yaml
  - /path/to/agentos/my-agent.yaml
  - /path/to/agentos/examples/my-agent.yaml
```

### ✅ Flexible Path Handling
- Absolute paths: `/full/path/to/manifest.yaml`
- Relative paths: `./configs/manifest.yaml`
- Simple names: `default.yaml` (searches multiple locations)

### ✅ Programmatic Access
```python
from agentos.core.path_resolver import resolve_manifest_path, find_all_manifests

# Find specific manifest
path = resolve_manifest_path("my-agent.yaml")

# Find all manifests
all_manifests = find_all_manifests()
```

## Testing

### Test Case 1: Run from Different Directories
```bash
# Test 1: From project root
cd /media/abdulhadi/New\ Volume/AbdulHadi/Projects/AgentOS
agentos run default.yaml --task "test"

# Test 2: From home directory
cd ~
agentos run default.yaml --task "test"

# Test 3: From /tmp
cd /tmp
agentos run default.yaml --task "test"

# Expected: All three work correctly
```

### Test Case 2: Web UI from Different Directories
```bash
# Test 1: From project root
cd /path/to/agentos
agentos ui

# Test 2: From home directory
cd ~
agentos ui

# Expected: Web UI loads correctly in both cases
```

### Test Case 3: Manifest Discovery
```bash
# Test 1: List manifests from project root
cd /path/to/agentos
agentos run --help  # Should show available manifests

# Test 2: List manifests from home directory
cd ~
agentos run --help  # Should show available manifests

# Expected: Same manifests found in both cases
```

## Migration Guide

### For Users

**No changes required!** The system is backward compatible.

Existing commands continue to work:
```bash
agentos run default.yaml --task "your task"
agentos run /full/path/to/manifest.yaml --task "your task"
agentos run ./relative/path/manifest.yaml --task "your task"
```

### For Developers

If you're extending AgentOS, use the path resolver:

```python
from agentos.core.path_resolver import (
    resolve_manifest_path,
    get_project_root,
    get_examples_dir,
    find_all_manifests
)

# Find a manifest
manifest = resolve_manifest_path("my-agent.yaml")

# Get project directories
root = get_project_root()
examples = get_examples_dir()

# Find all manifests
all = find_all_manifests()
```

   ```yaml
   # ~/.agentos/config.yaml
   search_paths:
     - /custom/manifests
     - /another/location
   ```

2. **Environment Variables**: Support custom paths via env vars
   ```bash
   export AGENTOS_MANIFEST_PATH="/my/manifests"
   ```

3. **Manifest Registry**: Central registry of available manifests
   ```bash
   agentos manifest list
   agentos manifest search "keyword"
   ```

4. **Path Caching**: Cache resolved paths for faster lookups
   ```python
   from agentos.core.path_resolver import cache_manifest_path
   ```

## Conclusion

The path resolution system makes AgentOS more robust and user-friendly by:

- ✅ Allowing operation from any directory
- ✅ Providing intelligent file discovery
- ✅ Maintaining centralized data storage
- ✅ Offering better error messages
- ✅ Supporting programmatic access
- ✅ Remaining fully backward compatible

Users can now run AgentOS from anywhere without worrying about file locations or working directories.
