## Feature Implementation Summary

### 1. Post-Installation Configuration Testing ✅

**Implementation**: `codex_configure.py`
```python
# New function added
async def verify_codex_configuration() -> tuple[bool, str]:
    """
    Verify the Codex CLI configuration by testing the MCP server.
    Returns (success, message).
    """
```

**Features**:
- Attempts to start MCP server in test mode
- Validates server responds to initialization
- Provides clear success/failure feedback
- Handles errors gracefully with actionable messages

**Lines Added**: ~80 lines
**Tests Added**: 1 new test in `test_codex_config.py`

---

### 2. Linear Team URL Derivation ✅

**Implementation**: `linear_commands.py`
```python
async def derive_team_from_url(url: str) -> tuple[str | None, str | None]:
    """
    Derive Linear team ID from a team URL.

    Supports formats:
    - https://linear.app/workspace
    - https://linear.app/workspace/team/TEAM-123
    - https://linear.app/workspace/issue/TEAM-123

    Returns (team_id, error_message).
    """
```

**Features**:
- Automatically extracts team info from Linear URLs
- Queries Linear API to validate and get team ID
- Supports workspace URLs, team URLs, and issue URLs
- Provides helpful error messages for invalid URLs

**Integration**: Enhanced `init` command in `main.py`:
```python
if team_input.startswith("https://linear.app/"):
    console.print("[cyan]Detected team URL, deriving team ID...[/cyan]")
    import asyncio
    from .linear_commands import derive_team_from_url

    derived_team_id, error = asyncio.run(
        derive_team_from_url(team_input)
    )
```

**Lines Added**: ~70 lines (core function + integration)

---

### 3. Command Rename: diagnose → doctor ✅

**Implementation**: `main.py`
```python
@app.command("doctor")
def doctor_command(
    output_file: str | None = typer.Option(
        None, "--output", "-o", help="Output file for the report"
    ),
    json_output: bool = typer.Option(
        False, "--json", help="Output as JSON"
    ),
) -> None:
    """
    Run comprehensive diagnostics to check system health.

    The 'doctor' command performs health checks on:
    - Adapter configuration and connectivity
    - API credentials and permissions
    - System dependencies
    - Common configuration issues
    """
```

**Features**:
- New primary command: `mcp-ticketer doctor`
- Backward compatibility: `diagnose` command hidden but still functional
- Clear alias relationship documented
- Updated help text and docstrings

**Files Modified**:
- `main.py`: Renamed command, added alias
- `adapter_diagnostics.py`: Updated docstring reference
- All documentation files: Updated command references

---

## Code Quality Improvements

### Exception Chaining (B904)
**Issue**: 9 instances of exceptions raised without proper chaining
**Fix**: Added `from e` or `from None` to all exception raises
**Impact**: Better error traceability and debugging

**Example**:
```python
# Before
except Exception as e:
    console.print(f"[red]✗ Configuration failed:[/red] {e}")
    raise typer.Exit(1)

# After
except Exception as e:
    console.print(f"[red]✗ Configuration failed:[/red] {e}")
    raise typer.Exit(1) from e
```

**Locations Fixed**:
1. Line 384: Setup cancellation
2. Line 1614: Comment addition failure
3. Line 1864: Diagnostics failure fallback
4. Line 2058: Installation failure
5. Line 2163: Removal failure
6. Line 2372: Claude MCP config failure
7. Line 2419: Gemini MCP config failure
8. Line 2451: Codex MCP config failure
9. Line 2483: Auggie MCP config failure

---

### Import Organization (I001)
**Issue**: 1 instance of unsorted imports
**Fix**: Auto-fixed by ruff
**Impact**: Consistent code style

---

### F-String Optimization (F541)
**Issue**: 1 f-string without placeholders
**Fix**: Auto-fixed by ruff to remove unnecessary `f` prefix
**Impact**: Cleaner code, minor performance improvement

---

### Docstring Improvement (D401)
**Issue**: 1 non-imperative docstring
**Fix**: Changed "Main entry point." to "Execute the main CLI application entry point."
**Impact**: Consistent documentation style

---
