Add a new integer phase to the end of the current milestone in the roadmap. Automatically calculates next phase number, creates phase directory, and updates roadmap structure.

<required_reading> Read all files referenced by the invoking prompt's execution_context before starting. </required_reading>

Parse the command arguments: - All arguments become the phase description - Example: `/gsd-add-phase Add authentication` → description = "Add authentication" - Example: `/gsd-add-phase Fix critical performance issues` → description = "Fix critical performance issues"

If no arguments provided:

ERROR: Phase description required
Usage: /gsd-add-phase <description>
Example: /gsd-add-phase Add authentication system

Exit.

Load phase operation context:

_GSD_SHIM_NAME="gsd-tools.cjs"; _GSD_RUNTIME_ROOT="${RUNTIME_DIR:-$(git rev-parse --show-toplevel 2>/dev/null || pwd)}"; GSD_TOOLS="${_GSD_RUNTIME_ROOT}/get-shit-done/bin/${_GSD_SHIM_NAME}"; if [ -f "$GSD_TOOLS" ]; then gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${_GSD_RUNTIME_ROOT}/.claude/get-shit-done/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${_GSD_RUNTIME_ROOT}/.claude/get-shit-done/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif command -v gsd-tools >/dev/null 2>&1; then GSD_TOOLS="$(command -v gsd-tools)"; gsd_run() { "$GSD_TOOLS" "$@"; }; elif [ -f "$HOME/.claude/get-shit-done/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="$HOME/.claude/get-shit-done/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; else echo "ERROR: gsd-tools.cjs not found at $GSD_TOOLS and gsd-tools is not on PATH. Run: npx -y @opengsd/gsd-core@latest --claude --local" >&2; exit 1; fi
INIT=$(gsd_run query init.phase-op "0")
if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi

Check roadmap_exists from init JSON. If false:

ERROR: No roadmap found (.planning/ROADMAP.md)
Run /gsd:new-project to initialize.

Exit.

**Delegate the phase addition to `gsd-tools.cjs query phase.add`:**

RESULT=$(gsd_run query phase.add "${description}")

The CLI handles:

• Finding the highest existing integer phase number
• Calculating next phase number (max + 1)
• Generating slug from description
• Creating the phase directory (.planning/phases/{NN}-{slug}/)
• Inserting the phase entry into ROADMAP.md with Goal, Depends on, and Plans sections

Extract from result: phase_number, padded, name, slug, directory.

Update STATE.md to reflect the new phase:

1. Read .planning/STATE.md
2. Under "## Accumulated Context" → "### Roadmap Evolution" add entry:

   - Phase {N} added: {description}
   

If "Roadmap Evolution" section doesn't exist, create it.

Present completion summary:

Phase {N} added to current milestone:
- Description: {description}
- Directory: .planning/phases/{phase-num}-{slug}/
- Status: Not planned yet

Roadmap updated: .planning/ROADMAP.md

## ▶ Next Up — [${PROJECT_CODE}] ${PROJECT_TITLE}

**Phase {N}: {description}**

`/clear` then:

`/gsd:plan-phase {N}`

**Also available:**
- `/gsd-add-phase <description>` — add another phase
- Review roadmap
