Default flow: Research (if needed) → Plan → Verify → Done
Orchestrator role: Parse arguments, validate phase, research domain (unless skipped or exists), spawn kata-planner agent, verify plans with kata-plan-checker, iterate until plans pass or max iterations reached, present results.
Why subagents: Research and planning burn context fast. Verification uses fresh context. User sees the flow between agents in main context.
Flags:
--research— Force re-research even if RESEARCH.md exists--skip-research— Skip research entirely, go straight to planning--gaps— Gap closure mode (reads VERIFICATION.md, skips research)--skip-verify— Skip planner → checker verification loop
Normalize phase input in step 2 before any directory lookups.
1. Validate Environment and Resolve Model Profile
ls .planning/ 2>/dev/null
If not found: Error - user should run /kata:new-project first.
Resolve model profile for agent spawning:
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-phase-researcher | opus | sonnet | haiku |
| kata-planner | opus | opus | sonnet |
| kata-plan-checker | sonnet | sonnet | haiku |
Store resolved models for use in Task calls below.
2. Parse and Normalize Arguments
Extract from $ARGUMENTS:
- Phase number (integer or decimal like
2.1) --researchflag to force re-research--skip-researchflag to skip research--gapsflag for gap closure mode--skip-verifyflag to bypass verification loop
If no phase number: Detect next unplanned phase from roadmap.
Normalize phase to zero-padded format:
# Normalize phase number (8 → 08, but preserve decimals like 2.1 → 02.1)
if [[ "$PHASE" =~ ^[0-9]+$ ]]; then
PHASE=$(printf "%02d" "$PHASE")
elif [[ "$PHASE" =~ ^([0-9]+)\.([0-9]+)$ ]]; then
PHASE=$(printf "%02d.%s" "${BASH_REMATCH[1]}" "${BASH_REMATCH[2]}")
fi
Check for existing research and plans:
ls .planning/phases/${PHASE}-*/*-RESEARCH.md 2>/dev/null
ls .planning/phases/${PHASE}-*/*-PLAN.md 2>/dev/null
3. Validate Phase
grep -A5 "Phase ${PHASE}:" .planning/ROADMAP.md 2>/dev/null
If not found: Error with available phases. If found: Extract phase number, name, description.
4. Ensure Phase Directory Exists
# PHASE is already normalized (08, 02.1, etc.) from step 2
PHASE_DIR=$(ls -d .planning/phases/${PHASE}-* 2>/dev/null | head -1)
if [ -z "$PHASE_DIR" ]; then
# Create phase directory from roadmap name
PHASE_NAME=$(grep "Phase ${PHASE}:" .planning/ROADMAP.md | sed 's/.*Phase [0-9]*: //' | tr '[:upper:]' '[:lower:]' | tr ' ' '-')
mkdir -p ".planning/phases/${PHASE}-${PHASE_NAME}"
PHASE_DIR=".planning/phases/${PHASE}-${PHASE_NAME}"
fi
5. Handle Research
If --gaps flag: Skip research (gap closure uses VERIFICATION.md instead).
If --skip-research flag: Skip to step 6.
Check config for research setting:
WORKFLOW_RESEARCH=$(cat .planning/config.json 2>/dev/null | grep -o '"research"[[:space:]]*:[[:space:]]*[^,}]*' | grep -o 'true\|false' || echo "true")
If workflow.research is false AND --research flag NOT set: Skip to step 6.
Otherwise:
Check for existing research:
ls "${PHASE_DIR}"/*-RESEARCH.md 2>/dev/null
If RESEARCH.md exists AND --research flag NOT set:
- Display:
Using existing research: ${PHASE_DIR}/${PHASE}-RESEARCH.md - Skip to step 6
If RESEARCH.md missing OR --research flag set:
Display stage banner:
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Kata ► RESEARCHING PHASE {X} ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
◆ Spawning researcher...
Proceed to spawn researcher
Spawn kata-phase-researcher
Gather context for research prompt:
# Get phase description from roadmap
PHASE_DESC=$(grep -A3 "Phase ${PHASE}:" .planning/ROADMAP.md)
# Get requirements if they exist
REQUIREMENTS=$(cat .planning/REQUIREMENTS.md 2>/dev/null | grep -A100 "## Requirements" | head -50)
# Get prior decisions from STATE.md
DECISIONS=$(grep -A20 "### Decisions Made" .planning/STATE.md 2>/dev/null)
# Get phase context if exists
PHASE_CONTEXT=$(cat "${PHASE_DIR}/${PHASE}-CONTEXT.md" 2>/dev/null)
Fill research prompt and spawn:
<objective>
Research how to implement Phase {phase_number}: {phase_name}
Answer: "What do I need to know to PLAN this phase well?"
</objective>
<context>
**Phase description:**
{phase_description}
**Requirements (if any):**
{requirements}
**Prior decisions:**
{decisions}
**Phase context (if any):**
{phase_context}
</context>
<output>
Write research findings to: {phase_dir}/{phase}-RESEARCH.md
</output>
Task(
prompt=research_prompt,
subagent_type="kata-phase-researcher",
model="{researcher_model}",
description="Research Phase {phase}"
)
Handle Researcher Return
## RESEARCH COMPLETE:
- Display:
Research complete. Proceeding to planning... - Continue to step 6
## RESEARCH BLOCKED:
- Display blocker information
- Offer: 1) Provide more context, 2) Skip research and plan anyway, 3) Abort
- Wait for user response
6. Check Existing Plans
ls "${PHASE_DIR}"/*-PLAN.md 2>/dev/null
If exists: Offer: 1) Continue planning (add more plans), 2) View existing, 3) Replan from scratch. Wait for response.
7. Read Context Files
Read and store context file contents for the planner agent. The @ syntax does not work across Task() boundaries - content must be inlined.
Read these files using the Read tool:
.planning/STATE.md(required).planning/ROADMAP.md(required).planning/REQUIREMENTS.md(if exists)${PHASE_DIR}/*-CONTEXT.md(if exists)${PHASE_DIR}/*-RESEARCH.md(if exists)${PHASE_DIR}/*-VERIFICATION.md(if --gaps mode)${PHASE_DIR}/*-UAT.md(if --gaps mode)
Store all content for use in the Task prompt below.
8. Spawn kata-planner Agent

9. Handle Planner Return
Parse planner output:
## PLANNING COMPLETE:
- Display:
Planner created {N} plan(s). Files on disk. - If
--skip-verify: Skip to step 13 - Check config:
WORKFLOW_PLAN_CHECK=$(cat .planning/config.json 2>/dev/null | grep -o '"plan_check"[[:space:]]*:[[:space:]]*[^,}]*' | grep -o 'true\|false' || echo "true") - If
workflow.plan_checkisfalse: Skip to step 13 - Otherwise: Proceed to step 10

Read plans and requirements for the checker:
# Read all plans in phase directory
PLANS_CONTENT=$(cat "${PHASE_DIR}"/*-PLAN.md 2>/dev/null)
# Read requirements (reuse from step 7 if available)
REQUIREMENTS_CONTENT=$(cat .planning/REQUIREMENTS.md 2>/dev/null)
Fill checker prompt with inlined content and spawn:
<verification_context>
**Phase:** {phase_number}
**Phase Goal:** {goal from ROADMAP}
**Plans to verify:**
{plans_content}
**Requirements (if exists):**
{requirements_content}
</verification_context>
<expected_output>

- ## ISSUES FOUND — structured issue list
</expected_output>
Task(
prompt=checker_prompt,
subagent_type="kata-plan-checker",
model="{checker_model}",
description="Verify Phase {phase} plans"
)
11. Handle Checker Return

</instructions>
Task(
prompt=revision_prompt,
subagent_type="kata-planner",
model="{planner_model}",
description="Revise Phase {phase} plans"
)
- After planner returns → spawn checker again (step 10)
- Increment iteration_count
If iteration_count >= 3:
Display: Max iterations reached. {N} issues remain:
- List remaining issues
Offer options:
- Force proceed (execute despite issues)
- Provide guidance (user gives direction, retry)
- Abandon (exit planning)
Wait for user response.
13. GitHub Integration Check
Check config guards:
GITHUB_ENABLED=$(cat .planning/config.json 2>/dev/null | grep -o '"enabled"[[:space:]]*:[[:space:]]*[^,}]*' | grep -o 'true\|false' || echo "false")
ISSUE_MODE=$(cat .planning/config.json 2>/dev/null | grep -o '"issueMode"[[:space:]]*:[[:space:]]*"[^"]*"' | grep -o '"[^"]*"$' | tr -d '"' || echo "never")
If GITHUB_ENABLED != true OR ISSUE_MODE = never:
- Log:
Skipping GitHub issue update (github.enabled=${GITHUB_ENABLED}, issueMode=${ISSUE_MODE}) - Skip to
<offer_next>
If enabled, find phase issue:
# Get milestone version from ROADMAP.md
VERSION=$(grep -oE 'v[0-9]+\.[0-9]+(\.[0-9]+)?' .planning/ROADMAP.md | head -1 | tr -d 'v' || echo "")
if [ -z "$VERSION" ]; then
echo "Warning: Could not determine milestone version. Skipping GitHub issue update."
# Continue to offer_next (non-blocking)
fi
# Find phase issue number
ISSUE_NUMBER=$(gh issue list \
--label "phase" \
--milestone "v${VERSION}" \
--json number,title \
--jq ".[] | select(.title | startswith(\"Phase ${PHASE}:\")) | .number" \
2>/dev/null)
if [ -z "$ISSUE_NUMBER" ]; then
echo "Warning: Could not find GitHub Issue for Phase ${PHASE}. Skipping checklist update."
# Continue to offer_next (non-blocking)
fi
Build plan checklist from PLAN.md files:
PLAN_CHECKLIST=""
PLAN_COUNT=0
for plan_file in $(ls "${PHASE_DIR}"/*-PLAN.md 2>/dev/null | sort); do
PLAN_NUM=$(basename "$plan_file" | sed -E 's/.*-([0-9]+)-PLAN\.md/\1/')
# Extract brief objective from plan (first line after <objective>)
PLAN_OBJECTIVE=$(grep -A2 "<objective>" "$plan_file" | head -2 | tail -1 | sed 's/^ *//' | head -c 60)
# Fallback if objective extraction fails
if [ -z "$PLAN_OBJECTIVE" ]; then
PLAN_OBJECTIVE=$(basename "$plan_file" .md | sed 's/-PLAN$//' | sed 's/-/ /g')
fi
PLAN_CHECKLIST="${PLAN_CHECKLIST}- [ ] Plan ${PLAN_NUM}: ${PLAN_OBJECTIVE}
"
PLAN_COUNT=$((PLAN_COUNT + 1))
done
Update issue body with plan checklist:
# Read current issue body
ISSUE_BODY=$(gh issue view "$ISSUE_NUMBER" --json body --jq '.body' 2>/dev/null)
if [ -z "$ISSUE_BODY" ]; then
echo "Warning: Could not read issue #${ISSUE_NUMBER} body. Skipping update."
# Continue to offer_next (non-blocking)
fi
# Remove placeholder line and add checklist after ## Plans section
# Using awk for multiline manipulation
NEW_BODY=$(echo "$ISSUE_BODY" | awk -v checklist="$PLAN_CHECKLIST" '
/^## Plans$/ {
print
print ""
print checklist
getline # Skip blank line after ## Plans if exists
if ($0 ~ /^_Plans will be added/) next # Skip placeholder
if ($0 ~ /^<!-- Checklist/) next # Skip comment
if ($0 == "") next # Skip blank line before placeholder
print
next
}
/^_Plans will be added/ { next } # Remove placeholder anywhere
{ print }
')
# Check if Plans section exists, if not append it
if ! echo "$ISSUE_BODY" | grep -q "^## Plans"; then
NEW_BODY="${ISSUE_BODY}
## Plans
${PLAN_CHECKLIST}"
fi
# Write to temp file (handles special characters safely)
printf '%s\n' "$NEW_BODY" > /tmp/phase-issue-body.md
# Update issue
gh issue edit "$ISSUE_NUMBER" --body-file /tmp/phase-issue-body.md 2>/dev/null \
&& GITHUB_UPDATE_SUCCESS=true \
|| echo "Warning: Failed to update issue #${ISSUE_NUMBER}"
Track result for display:
Store ISSUE_NUMBER and PLAN_COUNT for display in <offer_next> if update succeeded.
After GitHub check completes (success or skip), proceed to Step 14.
Error handling principle: All GitHub operations are non-blocking. Missing issue, auth issues, or update failures warn but do not stop the planning workflow.
