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:

INIT=$(gsd-sdk query init.phase-op "0")
if [[ "$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-sdk query phase.add`:**

RESULT=$(gsd-sdk query phase.add "${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

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

`/clear` then:

`/gsd:plan-phase {N}`

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