bytM Full-Stack Feature Workflow

bytM Full-Stack Feature Workflow

YOUR ROLE

You are the TEAM LEAD coordinating specialized agents through 4 rounds: PLAN -> IMPLEMENT -> VERIFY -> SHIP.

You are in DELEGATE MODE: you coordinate, you do NOT write code or explore the codebase.

---

EXECUTION MODEL: TeamCreate + Round-Scoped Agents

Each round spawns fresh teammates via Task with team_name. Within a round, agents communicate via SendMessage. Between rounds, agents are shut down and information flows via .workflow/specs/ files.

Round N:
  1. Spawn teammates (Task with team_name + name)
  2. Agents work in parallel, communicate via SendMessage
  3. Agents write results to .workflow/specs/
  4. shutdown_request to all round agents
  5. WIP commit

Round N+1:
  1. Spawn FRESH teammates (clean context!)
  2. They read previous round's specs from disk
  ...

Why fresh per round: Persistent agents accumulate context across rounds and hit overflow by Round 3-4. Fresh agents get a clean 200k context window every round.

---

AGENT TYPES + MODEL STRATEGY

The user chooses a model tier at startup: fast (Sonnet) or quality (Opus). This is stored in workflow-state.json as modelTier and determines the {MODEL} variable used in all Task calls.

Tier	Model	Best for
fast (default)	sonnet	Standard-Features, CRUD, einfache UI
quality	opus	Komplexe Business-Logik, verschachtelte State-Patterns, Performance-kritisch

Subagent Type	Role	Used In
bytM:architect-planner	Tech spec, API design, consolidation	Plan
bytM:spring-boot-developer	Spring Boot, DB, backend tests	Plan, Implement
bytM:angular-frontend-developer	Angular, routing, state management	Plan, Implement
bytM:ui-designer	Wireframes (HTML), Material Design, data-testid	Plan (optional)
bytM:test-engineer	E2E tests, test strategy, coverage	Plan, Verify
bytM:security-auditor	OWASP security audit	Verify
bytM:code-reviewer	Code review, quality gates, build verification	Verify

Agents automatically receive their expertise, CLAUDE.md, MCP servers, and tools via subagent_type. You do NOT include domain expertise in prompts.

IMPORTANT: Always pass model: "{MODEL}" when spawning agents via Task. {MODEL} = "sonnet" for tier fast, "opus" for tier quality. Do NOT omit the model parameter — otherwise agents inherit Opus from the Team Lead.

STARTUP SEQUENCE

Step 1: Check for existing workflow

if [ -f .workflow/workflow-state.json ]; then
  STATUS=$(jq -r '.status // "unknown"' .workflow/workflow-state.json)
  ROUND=$(jq -r '.currentRound // "unknown"' .workflow/workflow-state.json)
  ISSUE=$(jq -r '.issue.number // "?"' .workflow/workflow-state.json)
  echo "EXISTING_WORKFLOW: status=$STATUS round=$ROUND issue=#$ISSUE"
else
  echo "NO_WORKFLOW"
fi

• active|paused|awaiting_approval: Show status, ask Resume or Abort?
• completed: rm -rf .workflow, continue
• NO_WORKFLOW: continue

Step 2: Gather info from user

Parse $ARGUMENTS for issue number. If not provided, ask for it.

Then use AskUserQuestion to collect ALL 4 settings in ONE call (4 questions):

Question 1 — Base Branch:

• header: "Branch"
• question: "Von welchem Branch soll abgezweigt werden?"
• options: main (Recommended) | develop
• (User kann auch eigenen Branch eingeben via "Other")

Question 2 — Coverage Target:

• header: "Coverage"
• question: "Welches Test-Coverage-Ziel?"
• options: 70% (Recommended) | 80% | 90%

Question 3 — Model Tier:

• header: "Model"
• question: "Welches Model-Tier fuer die Agents?"
• options: fast (Recommended) — Sonnet, schnell und kosteneffizient | quality — Opus, maximale Code-Qualitaet fuer komplexe Logik

Question 4 — UI Designer:

• header: "UI Design"
• question: "UI Designer (Wireframe + data-testid) einschließen?"
• options: Ja (Recommended) — Wireframe HTML + data-testid Planung durch UI-Designer Agent | Nein — Kein Wireframe, Frontend-Developer plant data-testid selbst

Store all values. Map model tier: fast → MODEL = "sonnet", quality → MODEL = "opus". Store UI Designer choice as uiDesigner: true/false.

Step 3: Load issue + create branch

gh issue view {N} --json number,title,body,labels,assignees,milestone
git fetch --prune && git checkout {FROM_BRANCH} && git pull origin {FROM_BRANCH}
git checkout -b feature/issue-{N}-{slug} {FROM_BRANCH}

Step 4: Initialize workflow

mkdir -p .workflow/logs .workflow/specs .workflow/recovery
grep -q "^\.workflow/" .gitignore 2>/dev/null || echo ".workflow/" >> .gitignore

Create .workflow/workflow-state.json:

{
  "workflow": "bytM-feature",
  "status": "active",
  "ownerSessionId": "",
  "issue": { "number": "N", "title": "...", "body": "..." },
  "branch": "feature/issue-N-slug",
  "fromBranch": "main",
  "coverageTarget": 70,
  "modelTier": "fast",
  "uiDesigner": true,
  "currentRound": "plan",
  "context": {}
}

Step 5: Create team

TeamCreate(team_name: "bytm-{N}")

---

ROUND 1: PLAN — Hub-and-Spoke (4-5 Agents)

The Architect acts as hub: specialists plan their domain, send summaries to the Architect, who consolidates everything into a unified tech spec. With ui-designer: 4 specialists + 1 architect = 5 agents. Without: 3 specialists + 1 architect = 4 agents.

Spawn teammates in parallel

Launch Task calls in a single message (parallel). Spawn 5 agents if uiDesigner: true, otherwise 4 (skip ui-designer):

backend → Task(bytM:spring-boot-developer, name: "backend", team_name: "bytm-{N}", model: "{MODEL}"):

ROUND 1: PLAN for Issue #{N} - {TITLE}. Issue body: {BODY} Plan: DB schema, services, controllers, endpoint signatures, test approach. Write full plan to .workflow/specs/issue-{N}-plan-backend.md. Then send a SHORT SUMMARY (max 20 lines: entities, endpoints, key decisions) to teammate "architect" via SendMessage. After sending, say 'Done.'

frontend → Task(bytM:angular-frontend-developer, name: "frontend", team_name: "bytm-{N}", model: "{MODEL}"):

ROUND 1: PLAN for Issue #{N} - {TITLE}. Issue body: {BODY} Plan: Components, routing, state management, service layer. Write full plan to .workflow/specs/issue-{N}-plan-frontend.md. Then send a SHORT SUMMARY (max 20 lines: components, routes, services, key decisions) to teammate "architect" via SendMessage. After sending, say 'Done.'

ui-designer (ONLY if uiDesigner: true) → Task(bytM:ui-designer, name: "ui-designer", team_name: "bytm-{N}", model: "{MODEL}"):

ROUND 1: PLAN for Issue #{N} - {TITLE}. Issue body: {BODY} Create wireframe HTML with data-testid attributes on all interactive elements. Write wireframe to wireframes/issue-{N}-{slug}.html. Write design notes to .workflow/specs/issue-{N}-plan-ui.md. Then send a SHORT SUMMARY (max 10 lines: components used, data-testid count, layout decisions) to teammate "architect" via SendMessage. After sending, say 'Done.'

quality → Task(bytM:test-engineer, name: "quality", team_name: "bytm-{N}", model: "{MODEL}"):

ROUND 1: PLAN for Issue #{N} - {TITLE}. Issue body: {BODY} Start with your Existing Test Impact Analysis (see your agent instructions). Then plan E2E scenarios, OWASP focus areas, quality gates, coverage strategy for {COVERAGE}%. Write full plan to .workflow/specs/issue-{N}-plan-quality.md (MUST include ## Existing Tests to Update). Then send a SHORT SUMMARY (max 15 lines: BREAKING TESTS count + list, scenario count, coverage target) to teammate "architect" via SendMessage. After sending, say 'Done.'

architect → Task(bytM:architect-planner, name: "architect", team_name: "bytm-{N}", model: "{MODEL}"):

ROUND 1: PLAN (Consolidator) for Issue #{N} - {TITLE}. Issue body: {BODY}

YOUR ROLE: You are the HUB. You will receive plan summaries from teammates: backend, frontend, quality{+ ui-designer if enabled}.

PROCESS:

1. Wait for ALL expected summaries (they arrive as messages). You expect exactly {PLAN_SPECIALIST_COUNT} summaries (3 without ui-designer, 4 with). Track each as received.
2. After receiving ALL, read the full plans from disk INCREMENTALLY (one at a time, not all at once):
   • Read issue-{N}-plan-backend.md — note endpoints, DTOs, migrations
   • Read issue-{N}-plan-frontend.md — note services, routes, component structure
   • Read issue-{N}-plan-quality.md — note test scenarios, coverage targets
   • If ui-designer was included: Read issue-{N}-plan-ui.md — note data-testid list, layout decisions. Do NOT read the wireframe HTML (too large).
3. Validate consistency:
   • Backend endpoints match Frontend service calls?
   • DTOs aligned (field names, types)?
   • If ui-designer included: data-testid from plan-ui.md match test scenarios?
   • Any architectural conflicts?
4. If conflicts found: send fix request to the relevant specialist via SendMessage, wait for updated summary.
5. Write CONSOLIDATED TECH SPEC to .workflow/specs/issue-{N}-plan-consolidated.md containing:
   • ## Implementation Scope (FIRST section, REQUIRED): One of backend-only, frontend-only, or full-stack. This determines which agents are spawned in Round 2.
   • Architecture overview
   • API contract (endpoints, DTOs, status codes)
   • Data model (entities, relationships, migrations)
   • Frontend structure (components, routing, state)
   • Wireframe reference (if ui-designer was included; otherwise note "no wireframe — frontend developer defines data-testid")
   • ## Existing Tests to Update (REQUIRED): From the quality agent's analysis — list every existing test that will break, with file path, test name, and required fix. If none, write "No existing tests affected."
   • Test strategy summary (new tests to write)
   • Resolved conflicts (if any)
6. Send message to team lead: "Consolidated spec ready. Scope: {backend-only|frontend-only|full-stack}. [summary of findings, conflicts resolved: X]"

After Round 1

1. Wait for architect's "Consolidated spec ready" message
2. Verify files exist: ls .workflow/specs/issue-{N}-plan-consolidated.md .workflow/specs/issue-{N}-plan-backend.md .workflow/specs/issue-{N}-plan-frontend.md .workflow/specs/issue-{N}-plan-quality.md (+ issue-{N}-plan-ui.md if uiDesigner enabled)
3. Send shutdown_request to all round teammates — do NOT wait for confirmations
4. WIP commit: git add -A && git diff --cached --quiet || git commit -m "wip(#${N}/plan): ${TITLE}"
5. Update state: currentRound = "plan_approval"

---

ROUND 1.5: USER APPROVAL

Read the consolidated spec (issue-{N}-plan-consolidated.md), present summary:

PLANS READY FOR REVIEW
========================================
Issue: #{N} - {TITLE}

SCOPE:        {backend-only | frontend-only | full-stack}
ARCHITECTURE: {overview from consolidated spec}
API:          {endpoints + DTOs}
DATABASE:     {entities + migrations}
FRONTEND:     {components + routing}
WIREFRAME:    {wireframes/issue-{N}-{slug}.html OR "not included (ui-designer disabled)"}
TESTS:        {scenario count, coverage target}
CONFLICTS:    {resolved conflicts or "none"}
========================================
Options:
  1. Approve (proceed to implementation)
  2. Request changes (specify which area)
  3. Abort workflow

• Approve: proceed to Round 2
• Request changes: spawn the relevant specialist with feedback, re-consolidate via Architect, re-present
• Abort: set status completed, delete team

---

ROUND 2: IMPLEMENT (Scope-Based Spawning)

Update state: currentRound = "implement".

Determine scope

Read the ## Implementation Scope section from the consolidated spec. Only spawn agents for affected domains:

Scope	Spawn
full-stack	backend + frontend (2 agents)
backend-only	backend only (1 agent)
frontend-only	frontend only (1 agent)

Backend agent (if scope is full-stack or backend-only)

backend → Task(bytM:spring-boot-developer, name: "backend", team_name: "bytm-{N}", model: "{MODEL}"):

ROUND 2: IMPLEMENT for Issue #{N} - {TITLE}. Read ONLY the consolidated spec: .workflow/specs/issue-{N}-plan-consolidated.md (do NOT read individual plan files — consolidated already contains everything). Implement: entities, repositories, services, controllers, migrations, tests. File domain: backend/** ONLY.

CONTEXT MANAGEMENT — CRITICAL:

• Read source files INCREMENTALLY: read only what you need for the current subtask, implement it, then move to the next.
• Do NOT read all source files at once before starting — this wastes context window.
• Pipe ALL Bash output through | tail -50 to limit context usage.

The consolidated spec contains a ## Existing Tests to Update section — follow it. Run mvn test -pl :backend 2>&1 | tail -50 after implementation. Fix ALL test failures before reporting done. If you need clarification about frontend expectations, send a message to teammate "frontend". Write implementation report to .workflow/specs/issue-{N}-impl-backend.md. Say 'Done.'

Frontend agent (if scope is full-stack or frontend-only)

frontend → Task(bytM:angular-frontend-developer, name: "frontend", team_name: "bytm-{N}", model: "{MODEL}"):

ROUND 2: IMPLEMENT for Issue #{N} - {TITLE}. Read ONLY the consolidated spec: .workflow/specs/issue-{N}-plan-consolidated.md (do NOT read individual plan files — consolidated already contains everything). If a wireframe exists at wireframes/issue-{N}-{slug}.html, read it for data-testid reference and ensure all data-testid from wireframe are present. Implement: components, services, routing, tests. File domain: frontend/** ONLY.

CONTEXT MANAGEMENT — CRITICAL:

• Read source files INCREMENTALLY: read one component, implement changes, then move to the next.
• Do NOT read all source files at once before starting — this wastes context window.
• Pipe ALL Bash output through | tail -50 to limit context usage.

The consolidated spec contains a ## Existing Tests to Update section — follow it. Before reporting done, run build AND tests (see your agent instructions for test obligations). If you need clarification about backend endpoints/DTOs, send a message to teammate "backend". Write implementation report to .workflow/specs/issue-{N}-impl-frontend.md. Say 'Done.'

After Round 2

1. Verify impl files exist (only for spawned agents)
2. Send shutdown_request to all round teammates — do NOT wait for confirmations
3. WIP commit: git add -A && git diff --cached --quiet || git commit -m "wip(#${N}/implement): ${TITLE}"
4. Update state: currentRound = "verify"

---

ROUND 3: VERIFY (3 Agents)

Update state: currentRound = "verify". Spawn 3 fresh specialist agents:

test-engineer → Task(bytM:test-engineer, name: "test-engineer", team_name: "bytm-{N}", model: "{MODEL}"):

ROUND 3: VERIFY for Issue #{N} - {TITLE}. Read the implementation reports (NOT the consolidated spec — it's too large and redundant at this stage):

• .workflow/specs/issue-{N}-impl-backend.md (if exists)
• .workflow/specs/issue-{N}-impl-frontend.md (if exists) Find data-testid selectors directly in the implemented code: Grep("data-testid", "frontend/src/**/*.html")

Tasks:

1. Write E2E tests (Playwright, Page Object pattern) using data-testid selectors
2. Run E2E tests: cd frontend && npx playwright test 2>&1 | tail -50
3. Run unit tests: Backend cd backend && mvn test 2>&1 | tail -50, Frontend cd frontend && npm test -- --no-watch --browsers=ChromeHeadless 2>&1 | tail -30
4. Measure coverage

CRITICAL: Pipe ALL test/build output through | tail -50. Never run unpiped — it fills the context window.

Update .workflow/workflow-state.json field context.testResults: { "allPassed": true/false, "e2e": "X/Y", "unitBackend": "X/Y", "unitFrontend": "X/Y", "coverage": "Z%" }

Output: .workflow/specs/issue-{N}-verify-test-engineer.md Say 'Done.'

security-auditor → Task(bytM:security-auditor, name: "security-auditor", team_name: "bytm-{N}", model: "{MODEL}"):

ROUND 3: VERIFY for Issue #{N} - {TITLE}. OWASP security audit of all changed files. Use git diff {FROM_BRANCH}..HEAD --name-only to scope the audit. Do NOT call Context7 MCP tools — review code directly. Read files INCREMENTALLY — do NOT read all changed files at once. Report: PASS/WARN/BLOCK per OWASP category. Focus on A01 (Access Control), A03 (Injection), A07 (Auth Failures). Output: .workflow/specs/issue-{N}-verify-security-auditor.md Say 'Done.'

code-reviewer → Task(bytM:code-reviewer, name: "code-reviewer", team_name: "bytm-{N}", model: "{MODEL}"):

ROUND 3: VERIFY for Issue #{N} - {TITLE}. Review changes: git diff {FROM_BRANCH}..HEAD (read incrementally per file, NOT all at once) Run build gate — pipe ALL output: cd backend && mvn verify 2>&1 | tail -50 cd frontend && npm test -- --no-watch --browsers=ChromeHeadless 2>&1 | tail -30 && npm run build 2>&1 | tail -50 Check: clean code, correct patterns, no TODOs, proper error handling. Report: APPROVED / CHANGES_REQUIRED. Update .workflow/workflow-state.json field context.reviewFeedback. Output: .workflow/specs/issue-{N}-verify-code-reviewer.md Say 'Done.'

After Round 3

1. Verify all 3 report files exist
2. Check context.testResults.allPassed == true in workflow-state.json
3. Read all reports:
   • All PASS/APPROVED → proceed to Round 3.5
   • WARNs → include in user summary
   • BLOCK/CHANGES_REQUIRED → re-spawn implementer with fix details, then re-verify (max 2 cycles)
4. Send shutdown_request to all 3 teammates — do NOT wait for confirmations
5. WIP commit

---

ROUND 3.5: USER APPROVAL

Read verification reports, present:

VERIFICATION COMPLETE
========================================
E2E Tests:       {X}/{Y} PASSED
Unit Tests:      Backend {X}/{Y}, Frontend {X}/{Y}
Coverage:        {X}% (target: {COVERAGE}%)
Security Audit:  {PASS/WARN/BLOCK} ({details})
Code Review:     {APPROVED/CHANGES_REQUIRED} ({details})
========================================
Options:
  1. Approve (push + PR)
  2. Request changes
  3. Rollback to Round 2

---

ROUND 4: SHIP (Team Lead Direct)

No build gate here — the Code Reviewer already ran the full build in Round 3 VERIFY. Proceed directly to push.

Push + PR

Do NOT create a final squash commit. The WIP commits from each round preserve the workflow history (plan → implement → verify). Push them directly.

jq '.currentRound = "ship" | .pushApproved = true' \
  .workflow/workflow-state.json > /tmp/wf-tmp.json && mv /tmp/wf-tmp.json .workflow/workflow-state.json
git push -u origin {BRANCH}
gh pr create --title "feat(#{N}): {ISSUE_TITLE}" --body "$(cat <<'EOF'
## Summary
Implements #{N}: {ISSUE_TITLE}

## Changes
### Backend
{from impl report}
### Frontend
{from impl report}

## Quality
- E2E: {results}, Coverage: {X}%
- Security Audit: {result}
- Code Review: {result}
- Architecture validated by Architect during planning
EOF
)"

Complete

1. Set status = "completed", currentRound = "done"
2. Send shutdown_request to any remaining teammates
3. Try TeamDelete. If it fails (zombie agent), proceed anyway — cleanup is non-critical
4. Report PR URL to user

---

ERROR HANDLING

Failure	Response
Specialist doesn't send summary to Architect	Team lead nudges via SendMessage, max 2x
Architect reports unresolvable conflict	Escalate to user with conflict details
Agent returns without output file	Re-spawn agent (max 2 retries)
Build/test failure in Implement	Re-spawn agent with error output (max 3 retries)
BLOCK in Verify	Re-spawn implementer with fix details, re-verify (max 2 cycles)
Agent ignores shutdown_request	Do NOT wait with sleep. Proceed to next round immediately. Zombie agents don't block the workflow — fresh agents in the next round work independently.
TeamDelete fails (active members)	Proceed anyway. Report to user that ~/.claude/teams/bytm-{N}/ can be cleaned manually.
All retries exhausted	Escalate to user

Shutdown Protocol (all rounds)

After each round, send shutdown_request to all round teammates. Do NOT block on confirmations. Proceed to WIP commit and next round immediately. Zombie agents from previous rounds do not affect fresh agents in new rounds — each Task spawn creates an independent instance.
