kata-add-milestone

<objective> 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. </objective>

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

<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 </context>

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 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:

markdown

## 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

markdown

## 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:

bash

GITHUB_ENABLED=$(cat .planning/config.json 2>/dev/null | grep -o '"enabled"[[:space:]]*:[[:space:]]*[^,}]*' | grep -o 'true\|false' || echo "false")

If
GITHUB_ENABLED=true
:

Step 1: Validate GitHub remote exists

bash

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":

bash

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":

bash

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)

bash

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)

bash

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

bash

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:

bash

COMMIT_PLANNING_DOCS=$(cat .planning/config.json 2>/dev/null | grep -o '"commit_docs"[[:space:]]*:[[:space:]]*[^,}]*' | grep -o 'true\|false' || echo "true")
git check-ignore -q .planning 2>/dev/null && COMMIT_PLANNING_DOCS=false

COMMIT_PLANNING_DOCS=false

: Skip git operations

COMMIT_PLANNING_DOCS=true

(default):

bash

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:

bash

MODEL_PROFILE=$(cat .planning/config.json 2>/dev/null | grep -o '"model_profile"[[:space:]]*:[[:space:]]*"[^"]*"' | grep -o '"[^"]*"$' | tr -d '"' || echo "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:

bash

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:

bash

    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:

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

markdown

### Milestone Scope Issues

Issues pulled into current milestone scope:
- "[issue-title]" (from: [issue-file-path], GitHub: #N if linked)

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

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.

bash

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)

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 inline migration, then recalculate NEXT_PHASE before continuing
- "Skip" — Continue without fixing (phase lookups may return wrong results)

If "Migrate now":

Run the migration logic from

Phase 9.5: Create Phase Issues (if enabled)

1. Check github.enabled - Skip silently if false

If
GITHUB_ENABLED=false
: Skip to Phase 10.

2. Check github.issueMode (auto | ask | never):

bash

ISSUE_MODE=$(cat .planning/config.json 2>/dev/null | grep -o '"issueMode"[[:space:]]*:[[:space:]]*"[^"]*"' | grep -o '"[^"]*"$' | tr -d '"' || echo "auto")

If "never": Skip phase issue creation silently, continue to Phase 10
If "ask": Use AskUserQuestion to prompt:
- header: "GitHub Phase Issues"
- question: "Create GitHub Issues for each phase in this milestone?"
- options:
  - "Yes" — Create issues for all phases
  - "No" — Skip issue creation for this milestone
If "auto" or user approved "Yes": Proceed with creation

3. Create phase label (idempotent):

bash

gh label create "phase" --color "0E8A16" --description "Kata phase tracking" --force 2>/dev/null || true

4. Get milestone number (from Phase 5.5):

bash

# Extract VERSION from current milestone (the one marked "In Progress")
VERSION=$(grep -E "^### v[0-9]+\.[0-9]+.*\(In Progress\)" .planning/ROADMAP.md | grep -oE "v[0-9]+\.[0-9]+(\.[0-9]+)?" | head -1 | tr -d 'v')

MILESTONE_NUM=$(gh api /repos/:owner/:repo/milestones --jq ".[] | select(.title==\"v${VERSION}\") | .number" 2>/dev/null)
if [ -z "$MILESTONE_NUM" ]; then
  echo "Warning: Could not find GitHub Milestone v${VERSION}. Skipping phase issue creation."
  # Continue without phase issues - skip to Phase 10
fi

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

The ROADMAP.md structure uses:

Milestone headers:

### v1.1.0 GitHub Integration (Planned)

### v{VERSION} {Name} (Status)

Phase headers:
```

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
