Lex Christopherson 24b933e018 fix: rename gsd-tools.js to .cjs to prevent ESM conflicts (closes #495)
Projects with "type": "module" in package.json cause Node to treat
gsd-tools.js as ESM, crashing on require(). The .cjs extension forces
CommonJS regardless of the host project's module configuration.

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:

PHASE_INFO=$(node ~/.claude/get-shit-done/bin/gsd-tools.cjs find-phase "${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.

# 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:

PHASE_CHECK=$(node ~/.claude/get-shit-done/bin/gsd-tools.cjs roadmap get-phase "${PHASE}")
if [ "$(echo "$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:

PHASE_DIR=$(node ~/.claude/get-shit-done/bin/gsd-tools.cjs find-phase "${PHASE}" --raw)
