## Implementation Details

### FR29: Query Command with Filter Support ✅

**Status:** ✅ Complete

**Implementation:**
- Created `src/tracertm/cli/commands/query.py`
- Supports `--filter` option with key=value syntax
- Supports multiple filters: `status=todo,view=FEATURE`
- Supports individual flags: `--status`, `--view`, `--priority`, etc.
- Integrated with JSON output (FR32)

**Examples:**
```bash
# Query by status
rtm query --filter status=todo

# Multiple filters
rtm query --filter status=todo,view=FEATURE

# With flags
rtm query --status in_progress --view CODE

# JSON output
rtm query --filter status=todo --json
```

**Tests:** `tests/integration/test_epic3_query_command.py` (6 tests)

---

### FR30: Export Formats ✅

**Status:** ✅ Enhanced (YAML added)

**Implementation:**
- Added `export_to_yaml()` function in `src/tracertm/cli/commands/export.py`
- Updated export command to support `yaml` format
- YAML export includes all project data (items, links, metadata)

**Supported Formats:**
- ✅ JSON (existing)
- ✅ YAML (new)
- ✅ CSV (existing)
- ✅ Markdown (existing)

**Examples:**
```bash
rtm export --format yaml
rtm export --format yaml --output data.yaml
```

**Tests:** `tests/integration/test_epic3_yaml_export.py` (3 tests)

---

### FR32: JSON Output Flag ✅

**Status:** ✅ Complete

**Implementation:**
- Added `--json` flag to `item list` command
- Added `--json` flag to `query` command
- JSON output provides structured data for agent/script consumption
- Maintains backward compatibility with table output (default)

**Examples:**
```bash
# Item list with JSON
rtm item list --json

# Query with JSON
rtm query --filter status=todo --json
```

**Tests:** `tests/integration/test_epic3_json_output.py` (3 tests)

---

### FR33: Command Aliases ✅

**Status:** ✅ Complete

**Implementation:**
- Created `src/tracertm/cli/aliases.py` with alias mapping
- Provides convenient shortcuts for common commands
- Aliases can be resolved programmatically

**Available Aliases:**
- `p`, `proj` → `project`
- `i`, `items` → `item`
- `v`, `views` → `view`
- `l`, `links` → `link`
- `q` → `query`
- `s`, `find` → `search`
- `e`, `exp` → `export`
- `st`, `status` → `state`
- `h`, `hist` → `history`
- `c`, `cfg` → `config`

**Examples:**
```bash
# Using aliases
rtm p list          # project list
rtm i list          # item list
rtm q --filter status=todo  # query --filter status=todo
```

**Tests:** `tests/integration/test_epic3_command_aliases.py` (4 tests)

---

### FR34: Shell Completion ✅

**Status:** ✅ Complete (Typer built-in)

**Implementation:**
- Typer provides built-in shell completion
- Enabled via `add_completion=True` in main app
- Supports Bash, Zsh, and Fish

**Setup:**
```bash
# Bash
eval "$(_RTM_COMPLETE=bash_source rtm)"

# Zsh
eval "$(_RTM_COMPLETE=zsh_source rtm)"

# Fish
eval (env _RTM_COMPLETE=fish_source rtm)
```

**Verification:** ✅ Typer's completion system is active and working

---

### FR35: Config from YAML and Environment Variables ✅

**Status:** ✅ Complete

**Implementation:**
- `ConfigManager` supports hierarchical configuration:
  1. CLI flags (highest precedence)
  2. Environment variables (`TRACERTM_*`)
  3. Project config (`~/.tracertm/projects/<id>/config.yaml`)
  4. Global config (`~/.tracertm/config.yaml`)

**Environment Variables:**
- `TRACERTM_DATABASE_URL`
- `TRACERTM_CURRENT_PROJECT_ID`
- `TRACERTM_DEFAULT_VIEW`
- `TRACERTM_OUTPUT_FORMAT`
- `TRACERTM_LOG_LEVEL`

**Verification:** ✅ ConfigManager implements full hierarchy
