name	kata-add-milestone
description	Add a milestone to an existing project, starting a new milestone cycle, creating the first milestone after project init, or defining what's next after completing work. Triggers include "add milestone", "new milestone", "start milestone", "create milestone", "first milestone", "next milestone", and "milestone cycle".
metadata	{"version":"0.1.0"}

Add a milestone to the project through unified flow: questioning → research (optional) → requirements → roadmap.

This works for both first milestone (after /kata-new-project) and subsequent milestones (after completing a milestone).

Creates/Updates:

• .planning/PROJECT.md — updated with new milestone goals
• .planning/research/ — domain research (optional, focuses on NEW features)
• .planning/REQUIREMENTS.md — scoped requirements for this milestone
• .planning/ROADMAP.md — phase structure (creates if first, continues if subsequent)
• .planning/STATE.md — reset for new milestone (creates if first)

After this command: Run /kata-plan-phase [N] to start execution.

<execution_context> @./references/questioning.md @./references/ui-brand.md @./references/project-template.md @./references/requirements-template.md @./references/github-mapping.md </execution_context>

Milestone name: $ARGUMENTS (optional - will prompt if not provided)

Load project context: @.planning/PROJECT.md @.planning/STATE.md @.planning/MILESTONES.md @.planning/config.json

Load milestone context (if exists): @.planning/MILESTONE-CONTEXT.md

Phase 1: Load Context

• Read PROJECT.md (existing project, Validated requirements, decisions)
• Read MILESTONES.md (what shipped previously)
• Read STATE.md (pending todos, blockers)
• Check for MILESTONE-CONTEXT.md (if exists)

Phase 1.2: Pre-flight Roadmap Format Check

If ROADMAP.md exists, check format and auto-migrate if old:

if [ -f .planning/ROADMAP.md ]; then
  node "${CLAUDE_PLUGIN_ROOT}/skills/kata-add-milestone/scripts/kata-lib.cjs" check-roadmap 2>/dev/null
  FORMAT_EXIT=$?

  if [ $FORMAT_EXIT -eq 1 ]; then
    echo "Old roadmap format detected. Running auto-migration..."
  fi
fi

If exit code 1 (old format):

Invoke kata-doctor in auto mode:

Skill("kata-doctor", "--auto")

Continue after migration completes.

If exit code 0 or 2: Continue silently.

# Validate config
node "${CLAUDE_PLUGIN_ROOT}/skills/kata-add-milestone/scripts/kata-lib.cjs" check-config 2>/dev/null || true

Phase 1.5: Optional Brainstorm

Use AskUserQuestion:

• header: "Brainstorm"
• question: "Brainstorm ideas before defining milestone goals?"
• options:
  • "Brainstorm first" — Run explorer/challenger brainstorm session
  • "Skip" — Continue without brainstorming

If "Brainstorm first":

Display:

Launching brainstorm session...

Run /kata-brainstorm

After brainstorm completes, continue to Phase 2.

If "Skip": Continue to Phase 2.

Phase 2: Gather Milestone Goals

If MILESTONE-CONTEXT.md exists:

• Use features and scope from the context file
• Present summary for confirmation

If no context file:

• Present what shipped in last milestone
• Ask: "What do you want to build next?"
• Use AskUserQuestion to explore features
• Probe for priorities, constraints, scope

Phase 3: Determine Milestone Version

• Parse last version from MILESTONES.md
• Suggest next version (v1.0 → v1.1, or v2.0 for major)
• Confirm with user

Phase 4: Update PROJECT.md

Add/update these sections:

## Current Milestone: v[X.Y] [Name]

**Goal:** [One sentence describing milestone focus]

**Target features:**

- [Feature 1]
- [Feature 2]
- [Feature 3]

Update Active requirements section with new goals.

Update "Last updated" footer.

Phase 5: Update STATE.md

## Current Position

Phase: Not started (defining requirements)
Plan: —
Status: Defining requirements
Last activity: [today] — Milestone v[X.Y] started

Keep Accumulated Context section (decisions, blockers) from previous milestone.

Phase 5.5: Create GitHub Milestone (if enabled)

Read GitHub config:

GITHUB_ENABLED=$(node "${CLAUDE_PLUGIN_ROOT}/skills/kata-add-milestone/scripts/kata-lib.cjs" read-config "github.enabled" "false")

If GITHUB_ENABLED=true:

Step 1: Validate GitHub remote exists

HAS_GITHUB_REMOTE=$(git remote -v 2>/dev/null | grep -q 'github\.com' && echo "true" || echo "false")

If HAS_GITHUB_REMOTE=false:

Use AskUserQuestion to offer repo creation:

• header: "GitHub Repository"
• question: "GitHub tracking is enabled but no GitHub remote found. Create a repository now?"
• options:
  • "Yes, create private repo (Recommended)" — Create private repository and push
  • "Yes, create public repo" — Create public repository and push
  • "Skip for now" — Continue without GitHub integration

If "Yes, create private repo":

gh repo create --source=. --private --push

If successful, set HAS_GITHUB_REMOTE=true and continue to Step 2 (Check authentication).

If "Yes, create public repo":

gh repo create --source=. --public --push

If successful, set HAS_GITHUB_REMOTE=true and continue to Step 2 (Check authentication).

If "Skip for now": Display brief note and continue with local milestone initialization:

Continuing without GitHub integration. Run `gh repo create` later to enable.

Do NOT set github.enabled=false in config - user may add remote later.

If HAS_GITHUB_REMOTE=true:

Step 2: Check authentication (non-blocking)

if ! gh auth status &>/dev/null; then
  echo "Warning: GitHub CLI not authenticated. Run 'gh auth login' to enable GitHub integration."
  # Continue without GitHub operations - local milestone still created
else
  # Proceed with milestone creation
fi

Step 3: Check if milestone exists (idempotent)

MILESTONE_EXISTS=$(gh api /repos/:owner/:repo/milestones 2>/dev/null | jq -r ".[] | select(.title==\"v${VERSION}\") | .number" 2>/dev/null)

Step 4: Create milestone if doesn't exist

if [ -z "$MILESTONE_EXISTS" ]; then
  # Extract milestone description (first paragraph of goal, truncated to 500 chars)
  MILESTONE_DESC=$(echo "$MILESTONE_GOALS" | head -1 | cut -c1-500)

  gh api \
    --method POST \
    -H "Accept: application/vnd.github.v3+json" \
    /repos/:owner/:repo/milestones \
    -f title="v${VERSION}" \
    -f state='open' \
    -f description="${MILESTONE_DESC}" \
    2>/dev/null && echo "GitHub Milestone v${VERSION} created" || echo "Warning: Failed to create GitHub Milestone (continuing)"
else
  echo "GitHub Milestone v${VERSION} already exists (#${MILESTONE_EXISTS})"
fi

If GITHUB_ENABLED=false:

Skip GitHub operations silently (no warning needed - user opted out).

Error handling principle:

• All GitHub operations are non-blocking
• Missing remote warns but does not stop milestone initialization
• Auth failures warn but do not stop milestone initialization
• Planning files always persist locally regardless of GitHub status

Phase 6: Cleanup and Commit

Delete MILESTONE-CONTEXT.md if exists (consumed).

Check planning config:

COMMIT_PLANNING_DOCS=$(node "${CLAUDE_PLUGIN_ROOT}/skills/kata-add-milestone/scripts/kata-lib.cjs" read-config "commit_docs" "true")
git check-ignore -q .planning 2>/dev/null && COMMIT_PLANNING_DOCS=false

If COMMIT_PLANNING_DOCS=false: Skip git operations

If COMMIT_PLANNING_DOCS=true (default):

git add .planning/PROJECT.md .planning/STATE.md
git commit -m "docs: start milestone v[X.Y] [Name]"

Phase 6.5: Resolve Model Profile

Read model profile for agent spawning:

MODEL_PROFILE=$(node "${CLAUDE_PLUGIN_ROOT}/skills/kata-add-milestone/scripts/kata-lib.cjs" read-config "model_profile" "balanced")

Default to "balanced" if not set.

Model lookup table:

Agent	quality	balanced	budget
kata-project-researcher	opus	sonnet	haiku
kata-research-synthesizer	sonnet	sonnet	haiku
kata-roadmapper	opus	sonnet	sonnet

Store resolved models for use in Task calls below.

Phase 7: Research Decision

Use AskUserQuestion:

• header: "Research"
• question: "Research the domain ecosystem for new features before defining requirements?"
• options:
  • "Research first (Recommended)" — Discover patterns, expected features, architecture for NEW capabilities
  • "Skip research" — I know what I need, go straight to requirements

If "Research first":

Phase 7.5: Issue Selection

Check for backlog issues:

BACKLOG_COUNT=$(find .planning/issues/open -maxdepth 1 -name "*.md" 2>/dev/null | wc -l | tr -d ' ')

If BACKLOG_COUNT > 0:

Display: "Checking backlog for issues to include in this milestone..."

Build issue options dynamically:

ISSUE_OPTIONS=""
for file in .planning/issues/open/*.md; do
  [ -f "$file" ] || continue
  created=$(grep "^created:" "$file" | cut -d' ' -f2)
  title=$(grep "^title:" "$file" | cut -d':' -f2- | xargs)

    github_ref=" (GitHub $(echo "$provenance" | grep -oE '#[0-9]+')"
  fi

  echo "$file|$title|$area|$age$github_ref"
done

Use AskUserQuestion:

• header: "Backlog Issues"
• question: "Include any backlog issues in this milestone's scope?"
• multiSelect: true
• options: Build from issue list above, format as "[title]" — [area], [age]
• Include final option: "None — Start fresh"

For each selected issue (if not "None — Start fresh"):

Store as SELECTED_ISSUES variable for use in Phase 8.

Update STATE.md with milestone scope issues:

1. Read STATE.md
2. Find or create "### Milestone Scope Issues" section
3. Add each selected issue:

### Milestone Scope Issues

Issues pulled into current milestone scope:

- "[issue-title]" (from: [issue-file-path], GitHub: #N if linked)

4. Write updated STATE.md

Purpose of issue selection:

• Selected issues become formally tracked as part of the milestone scope
• They appear in STATE.md under "### Milestone Scope Issues" for the current milestone
• They inform requirements generation in Phase 8 (planner should consider these issues when generating requirements)
• They will be visible in progress tracking commands like /kata-track-progress
• User still defines formal requirements through Phase 8, but selected issues provide explicit scope context

If BACKLOG_COUNT = 0:

Skip silently. Continue to Phase 8.

Phase 8: Define Requirements

Display stage banner:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Kata ► DEFINING REQUIREMENTS ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Load context:

Read PROJECT.md and extract:

• Core value (the ONE thing that must work)
• Current milestone goals
• Validated requirements (what already exists)

If research exists: Read research/FEATURES.md and extract feature categories.

Present features by category:

Here are the features for [new capabilities]:

## [Category 1]
**Table stakes:**
- Feature A
- Feature B

**Differentiators:**
- Feature C
- Feature D

**Research notes:** [any relevant notes]

---

## [Next Category]
...

If no research: Gather requirements through conversation instead.

Ask: "What are the main things users need to be able to do with [new features]?"

For each capability mentioned:

• Ask clarifying questions to make it specific
• Probe for related capabilities
• Group into categories

Scope each category:

For each category, use AskUserQuestion:

• header: "[Category name]"
• question: "Which [category] features are in this milestone?"
• multiSelect: true
• options:
  • "[Feature 1]" — [brief description]
  • "[Feature 2]" — [brief description]
  • "[Feature 3]" — [brief description]
  • "None for this milestone" — Defer entire category

Track responses:

• Selected features → this milestone's requirements
• Unselected table stakes → future milestone
• Unselected differentiators → out of scope

Identify gaps:

Use AskUserQuestion:

• header: "Additions"
• question: "Any requirements research missed? (Features specific to your vision)"
• options:
  • "No, research covered it" — Proceed
  • "Yes, let me add some" — Capture additions

Generate REQUIREMENTS.md:

Create .planning/REQUIREMENTS.md with:

• v1 Requirements for THIS milestone grouped by category (checkboxes, REQ-IDs)
• Future Requirements (deferred to later milestones)
• Out of Scope (explicit exclusions with reasoning)
• Traceability section (empty, filled by roadmap)

REQ-ID format: [CATEGORY]-[NUMBER] (AUTH-01, NOTIF-02)

Continue numbering from existing requirements if applicable.

Requirement quality criteria:

Good requirements are:

• Specific and testable: "User can reset password via email link" (not "Handle password reset")
• User-centric: "User can X" (not "System does Y")
• Atomic: One capability per requirement (not "User can login and manage profile")
• Independent: Minimal dependencies on other requirements

Present full requirements list:

Show every requirement (not counts) for user confirmation:

## Milestone v[X.Y] Requirements

### [Category 1]
- [ ] **CAT1-01**: User can do X
- [ ] **CAT1-02**: User can do Y

### [Category 2]
- [ ] **CAT2-01**: User can do Z

[... full list ...]

Does this capture what you're building? (yes / adjust)

If "adjust": Return to scoping.

Commit requirements:

Check planning config (same pattern as Phase 6).

If committing:

git add .planning/REQUIREMENTS.md
git commit -m "$(cat <<'EOF'
docs: define milestone v[X.Y] requirements

EOF
)"

Phase 8.5: Collision Check

Check for duplicate phase numeric prefixes across all state directories. Collisions cause find ... -name "01-*" | head -1 to return wrong directories.

DUPES=$(for state in active pending completed; do
  ls .planning/phases/${state}/ 2>/dev/null
done | grep -oE '^[0-9]+' | sort -n | uniq -d)

# Include flat directories (unmigrated projects)
FLAT_DUPES=$(ls .planning/phases/ 2>/dev/null | grep -E '^[0-9]' | grep -oE '^[0-9]+' | sort -n | uniq -d)

ALL_DUPES=$(echo -e "${DUPES}\n${FLAT_DUPES}" | sort -nu | grep -v '^$')

If ALL_DUPES is empty: Continue silently to Phase 9.

If collisions found:

Display:

⚠ Duplicate phase prefixes detected: [list]

Phase directories share numeric prefixes across milestones. This causes
phase lookup commands to return wrong directories.

Use AskUserQuestion:

• header: "Collisions"
• question: "Duplicate phase prefixes found. Migrate to globally sequential numbering?"
• options:
  • "Migrate now" — Run /kata-doctor to fix collisions, then recalculate NEXT_PHASE before continuing
  • "Skip" — Continue without fixing (phase lookups may return wrong results)

If "Migrate now":

Run /kata-doctor to perform migration:

Skill("kata-doctor")

After doctor completes, recalculate NEXT_PHASE from the newly renumbered directories.

If "Skip":

Display:

⚠ Skipping migration. Run `/kata-doctor` to fix collisions later.

Continue to Phase 9.

Phase 9: Create Roadmap

Display stage banner:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Kata ► CREATING ROADMAP ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

◆ Spawning roadmapper...

Determine starting phase number:

Phase numbers are globally sequential across milestones. Scan all existing phase directories to find the highest phase number, then start this milestone's phases at highest + 1:

ALL_PHASE_DIRS=""
for state in active pending completed; do
  [ -d ".planning/phases/${state}" ] && ALL_PHASE_DIRS="${ALL_PHASE_DIRS} $(find .planning/phases/${state} -maxdepth 1 -type d -not -name "${state}" 2>/dev/null)"

5. Parse phases from ROADMAP.md (for this milestone only):

The ROADMAP.md structure uses:

• Milestone headers: ### v1.1.0 GitHub Integration (Planned) or ### v{VERSION} {Name} (Status)
• Phase headers: #### Phase N: Phase Name
• Goal line: **Goal**: description text
• Requirements line: **Requirements**: REQ-01, REQ-02 (optional)
• Success criteria: **Success Criteria** (what must be TRUE): followed by numbered list

# Find the milestone section and extract phases
ROADMAP_FILE=".planning/ROADMAP.md"

# Extract VERSION from current milestone
VERSION=$(grep -E "Current Milestone:|🔄" "$ROADMAP_FILE" | grep -oE 'v[0-9]+\.[0-9]+(\.[0-9]+)?' | head -1 | tr -d 'v')
if [ -z "$VERSION" ]; then
  echo "Warning: Could not determine milestone version. Skipping phase issue creation."
  exit 0
fi

# Get line numbers for milestone section boundaries
MILESTONE_START=$(grep -n "^### v${VERSION}" "$ROADMAP_FILE" | head -1 | cut -d: -f1)
NEXT_MILESTONE=$(awk -v start="$MILESTONE_START" 'NR > start && /^### v[0-9]/ {print NR; exit}' "$ROADMAP_FILE")

# If no next milestone, use end of file
if [ -z "$NEXT_MILESTONE" ]; then
  NEXT_MILESTONE=$(wc -l < "$ROADMAP_FILE")
fi

# Extract phase blocks within this milestone section
# Each phase starts with "### Phase N:" or "#### Phase N:" and ends at next phase or section boundary
PHASE_HEADERS=$(sed -n "${MILESTONE_START},${NEXT_MILESTONE}p" "$ROADMAP_FILE" | grep -nE "^#{3,4} Phase [0-9]")

# Process each phase
echo "$PHASE_HEADERS" | while IFS= read -r phase_line; do
  # Extract phase number and name from "#### Phase N: Name"

  PHASE_NAME=$(echo "$phase_line" | sed -E 's/.*Phase [0-9.]+: (.*)/\1/')

  # Get relative line number within milestone section
  PHASE_REL_LINE=$(echo "$phase_line" | cut -d: -f1)
  PHASE_ABS_LINE=$((MILESTONE_START + PHASE_REL_LINE - 1))

  # Find next phase or section end
  NEXT_PHASE_LINE=$(sed -n "$((PHASE_ABS_LINE+1)),${NEXT_MILESTONE}p" "$ROADMAP_FILE" | grep -nE "^#{2,4} (Phase |v[0-9])" | head -1 | cut -d: -f1)
  if [ -z "$NEXT_PHASE_LINE" ]; then
    PHASE_END=$NEXT_MILESTONE
  else
    PHASE_END=$((PHASE_ABS_LINE + NEXT_PHASE_LINE - 1))
  fi

  # Extract phase block
  PHASE_BLOCK=$(sed -n "${PHASE_ABS_LINE},${PHASE_END}p" "$ROADMAP_FILE")

  # Extract goal (line starting with **Goal**:)
  PHASE_GOAL=$(echo "$PHASE_BLOCK" | grep "^\*\*Goal\*\*:" | sed 's/\*\*Goal\*\*: *//')

  # Extract requirements (line starting with **Requirements**:) - may not exist
  REQUIREMENT_IDS=$(echo "$PHASE_BLOCK" | grep "^\*\*Requirements\*\*:" | sed 's/\*\*Requirements\*\*: *//')

  # Extract success criteria (numbered list after **Success Criteria**)
  # Convert to checklist format: "  1. item" -> "- [ ] item"
  SUCCESS_CRITERIA_AS_CHECKLIST=$(echo "$PHASE_BLOCK" | \
    awk '/^\*\*Success Criteria\*\*/{found=1; next} found && /^  [0-9]+\./{print} found && /^\*\*/{exit}' | \

6. Display summary (after loop):

◆ GitHub Phase Issues: [N] created for milestone v${VERSION}

Error handling principle: All operations are non-blocking. Missing milestone, auth issues, or creation failures warn but do not stop the milestone flow.

IMPORTANT: Use temp file approach (--body-file) to handle special characters in phase goals. Direct --body strings break with quotes/backticks.

Phase 10: Done

• PROJECT.md updated with Current Milestone section
• STATE.md reset for new milestone
• MILESTONE-CONTEXT.md consumed and deleted (if existed)
• Research completed (if selected) — 4 parallel agents spawned, milestone-aware
• Requirements gathered (from research or conversation)
• User scoped each category
• REQUIREMENTS.md created with REQ-IDs
• kata-roadmapper spawned with phase numbering context
• Roadmap files written immediately (not draft)
• User feedback incorporated (if any)
• ROADMAP.md created with globally sequential phase numbers (continuing from highest existing)
• All commits made (if planning docs committed)
• User knows next step is /kata-discuss-phase [N]

Atomic commits: Each phase commits its artifacts immediately. If context is lost, artifacts persist. </success_criteria>
