# Phase Argument Parsing
Parse and normalize phase arguments for commands that operate on phases.
## Extraction
From `$ARGUMENTS`:
- Extract phase number (first numeric argument)
- Extract flags (prefixed with `--`)
- Remaining text is description (for insert/add commands)
## Using gsd-tools
The `find-phase` command handles normalization and validation in one step:
```bash
PHASE_INFO=$(node "C:/Users/yaoji/.claude/get-shit-done/bin/gsd-tools.cjs" find-phase "${PHASE}")
```
Returns JSON with:
- `found`: true/false
- `directory`: Full path to phase directory
- `phase_number`: Normalized number (e.g., "06", "06.1")
- `phase_name`: Name portion (e.g., "foundation")
- `plans`: Array of PLAN.md files
- `summaries`: Array of SUMMARY.md files
## Manual Normalization (Legacy)
Zero-pad integer phases to 2 digits. Preserve decimal suffixes.
```bash
# Normalize phase number
if [[ "$PHASE" =~ ^[0-9]+$ ]]; then
# Integer: 8 → 08
PHASE=$(printf "%02d" "$PHASE")
elif [[ "$PHASE" =~ ^([0-9]+)\.([0-9]+)$ ]]; then
# Decimal: 2.1 → 02.1
PHASE=$(printf "%02d.%s" "${BASH_REMATCH[1]}" "${BASH_REMATCH[2]}")
fi
```
## Validation
Use `roadmap get-phase` to validate phase exists:
```bash
PHASE_CHECK=$(node "C:/Users/yaoji/.claude/get-shit-done/bin/gsd-tools.cjs" roadmap get-phase "${PHASE}")
if [ "$(printf '%s\n' "$PHASE_CHECK" | jq -r '.found')" = "false" ]; then
echo "ERROR: Phase ${PHASE} not found in roadmap"
exit 1
fi
```
## Directory Lookup
Use `find-phase` for directory lookup:
```bash
PHASE_DIR=$(node "C:/Users/yaoji/.claude/get-shit-done/bin/gsd-tools.cjs" find-phase "${PHASE}" --raw)
```
