Decimal Phase Calculation

Calculate the next decimal phase number for urgent insertions.

Using gsd-tools

# Get next decimal phase after phase 6
gsd-tools query phase.next-decimal 6

Output:

{
  "found": true,
  "base_phase": "06",
  "next": "06.1",
  "existing": []
}

With existing decimals:

{
  "found": true,
  "base_phase": "06",
  "next": "06.3",
  "existing": ["06.1", "06.2"]
}

Extract Values

DECIMAL_PHASE=$(gsd-tools query phase.next-decimal "${AFTER_PHASE}" --pick next)
BASE_PHASE=$(gsd-tools query phase.next-decimal "${AFTER_PHASE}" --pick base_phase)

Or with --raw flag:

DECIMAL_PHASE=$(gsd-tools query phase.next-decimal "${AFTER_PHASE}" --raw)
# Returns just: 06.1

Examples

Existing Phases	Next Phase
06 only	06.1
06, 06.1	06.2
06, 06.1, 06.2	06.3
06, 06.1, 06.3 (gap)	06.4

Directory Naming

Decimal phase directories use the full decimal number:

SLUG=$(gsd-tools query generate-slug "$DESCRIPTION" --raw)
PHASE_DIR=".planning/phases/${DECIMAL_PHASE}-${SLUG}"
mkdir -p "$PHASE_DIR"
