Ring:running Dev Cycle

Development Cycle Orchestrator

When to use

• Starting a new development cycle with a phased plan (plan.md from pre-dev or standalone ring:writing-plans)
• Resuming an interrupted development cycle
• Need structured, gate-based epic execution with quality checkpoints and phase cadence

Skip when

• No plan file exists
• Task is documentation-only or planning-only
• Frontend project (use ring:running-dev-cycle-frontend instead)

You orchestrate. Agents execute. You NEVER read, write, or edit source code directly.

How This Works

Load the phased plan (plan.md, ring:writing-plans canonical format) and execute the lean backend cycle. The plan is rolling-wave phased: a ## Phase Overview table (phases + milestone + status), phase sections containing ### Epic N.M: headings (each epic carries a **Status:** line: Pending/Doing/Done/Failed), and inline dispatch-ready #### Task N.M.T: blocks written under each epic of the currently-detailed wave. Only the active wave is task-detailed; later phases are epic-level and get elaborated at each phase boundary. Backend implementation owns local runtime and quality so the flow does not dispatch separate QA, SRE, or DevOps gates.

Vocabulary: Phase = independently verifiable checkpoint (internal rolling-wave structure). Epic (Epic N.M) = value-driven increment, the UNIT this cycle iterates. Task (Task N.M.T) = dispatch-ready unit, the Gate 0 execution unit.

Announce at start: "Using ring:running-dev-cycle lean backend flow (rolling-wave phased plan)."

Gate Map

Gate 0 includes TDD RED/GREEN, coverage threshold enforcement, docker-compose/local runtime updates, basic health/observability verification, and delivery verification. Do not dispatch separate QA, SRE, or DevOps gates as part of this cycle. Step 11.5 (phase cadence) closes the just-finished phase and rolling-wave elaborates the next phase's epics into dispatch-ready tasks — read gates/phase-boundary.md.

Execution Order

for each phase (current wave; starts at Phase 1, the only detailed phase at init):

  for each epic in this phase (plan order):

    # 1. TASK-LEVEL build (per task Task N.M.T, or epic-itself if no task breakdown)
    for each task:
      Gate 0  # build task
      [checkpoint if manual_per_task mode]

    # 2. EPIC-LEVEL review (once per epic, after all tasks are built)
    Gate 8  # review whole epic — 9 parallel reviewers see cumulative diff

    # 3-4. Fix CRITICAL/HIGH/MEDIUM, then re-review until clean (inside Gate 8)

    # 5. EPIC-LEVEL validation (once per epic, after review passes)
    Gate 9  # validate whole epic — aggregate EVERY task's acceptance criteria + ONE human approval
            # criterion FAIL → back to Gate 0 for that task, then re-review (step 2) → re-validate

    # 6. "Proceed to next epic?" checkpoint (Step 11.1) → next epic in this phase

  # 7. PHASE BOUNDARY (Step 11.5, after the LAST epic of the phase is approved) — read gates/phase-boundary.md
  #    Skill("ring:committing-changes")  ← commit all phase work BEFORE closing the phase
  #    ask user: "Open a PR for this phase?" → if yes: Skill("ring:opening-pull-requests")  ← optional
  #    close phase (Phase Overview → Complete, record deviations) →
  #    phase checkpoint (manual: ask Continue/Pause/Adjust | auto: log + continue) →
  #    elaborate next phase's epics into dispatch-ready tasks (1 planning agent, ANALYSIS mode) →
  #    validate elaboration → resume epic loop at Gate 0 for the new phase
  #    (no next phase → fall through to cycle-end)

# 8. CYCLE-END (once, after the LAST phase completes its boundary) — see "Cycle Completion"; read gates/cycle-completion.md
Final Test Confirmation → Multi-Tenant Verify → Migration Safety (Gate 0.5D, conditional) → dev-report → Final Commit

Gate Execution Workflow

For EVERY gate, follow this exact sequence:

1. Read gate-specific instructions  → Gate 0: Read("gates/gate-0-implementation.md"); Gate 8: Read("gates/gate-8-review.md"); Gate 9: Read("gates/gate-9-validation.md"); Phase boundary (Step 11.5): Read("gates/phase-boundary.md")
2. Load sub-skill                   → Skill("ring:{sub-skill-name}")
3. Follow sub-skill dispatch rules  → Sub-skill tells you HOW to dispatch
4. Dispatch agent                   → Task(subagent_type="ring:{agent}", ...)
5. Validate agent output            → Per sub-skill validation rules
6. Update state                     → Write to current-cycle.json
7. Next gate or checkpoint

Never dispatch an agent without loading the sub-skill first. Never skip from standards → agent directly. Always: standards → sub-skill → agent.

Standards Loading

At cycle start (Step 1.5), pre-cache Ring standards:

1. WebFetch the standards index for the project language (e.g., golang/index.md)
2. Store cached standards in state.cached_standards
3. Pass relevant modules to agents at dispatch time — do NOT re-fetch per gate

Orchestrator Boundaries

You CAN: Read task/state files, write state files, track progress, dispatch agents, ask user questions, WebFetch standards.

You CANNOT: Read/write/edit source code (*.go, *.ts, *.tsx), run tests, analyze code directly, make architectural decisions.

If a task involves source code → dispatch specialist agent. No exceptions regardless of file count or simplicity.

State Management

State lives in docs/ring:running-dev-cycle/current-cycle.json (or docs/ring:planning-backend-refactor/current-cycle.json).

For state schema, persistence rules, and initialization logic, read gates/state-schema.md from this skill directory.

Critical rule: Write state after EVERY gate completion. If state write fails → STOP. Never proceed without persisted state.

PROJECT_RULES.md Check

Before starting any gate execution, verify docs/PROJECT_RULES.md exists.

For the full verification process and template creation flow, read gates/project-rules-check.md from this skill directory.

If PROJECT_RULES.md doesn't exist → create it using the Ring template before proceeding.

Cycle Completion

When the epic loop finishes the LAST phase (last epic of the last phase passed all its gates AND that phase's boundary at Step 11.5 found no next phase to elaborate), the cycle is NOT done — a completion phase runs once.

Read gates/cycle-completion.md from this skill directory and execute Steps 12.0–12.1 in order:

1. Step 12.0 — Cycle Exit Verification (HARD GATE: every Gate 0 handoff has passing tests, coverage ≥ threshold, local runtime; plus multi-tenant dual-mode verified for all units)
2. Step 12.0.5b — Gate 0.5D Migration Safety (conditional: runs only when SQL migration files appear in the cycle diff vs origin/main)
3. Step 12.1 — the one-and-only ring:writing-dev-reports dispatch, then Final Commit (which captures the feedback it generates)

⛔ The cycle is incomplete until Step 12.1 finishes. Do NOT declare the cycle done from the Execution Order summary alone — the detailed, mandatory steps live in gates/cycle-completion.md.

Execution Modes

Ask user at cycle start (independent questions, in the order given at the end of this section):

1. Execution mode (epic/task checkpoint cadence):

2. Phase checkpoint (state.phase_checkpoint):

Mode and phase_checkpoint affect CHECKPOINTS (user approval pauses), not GATES. All listed gates execute regardless of mode. The phase boundary's elaboration step runs in BOTH phase_checkpoint values — only the pause differs.

3. Commit timing (state.commit_timing ∈ {per_task, per_epic, at_end}): when commits happen during the cycle — see ## Commit Timing for what each value commits at which gate.

Resulting cycle-init question order: execution mode → phase checkpoint → commit timing.

Custom Instructions

If user provides custom context at cycle start, store in state.custom_prompt and inject at the top of every agent dispatch:

**CUSTOM CONTEXT (from user):**
{state.custom_prompt}

---

**Standard Instructions:**
[... agent prompt ...]

Commit Timing

• Gate 0 (implementation): Commit after GREEN phase, coverage, docker-compose/local runtime, and delivery verification pass (commit_timing == "per_task") via ring:committing-changes
• Gate 8 (review): Commit fixes after all reviewers pass via ring:committing-changes
• Gate 9 (validation): No commit (verification only); epic-level commit at Step 11.1 when commit_timing == "per_epic" via ring:committing-changes
• Phase boundary (Step 11.5): ALWAYS call Skill("ring:committing-changes") to commit all phase work before closing the phase, regardless of commit_timing. After the commit, ask the user: "Open a PR for this phase?" — if yes, call Skill("ring:opening-pull-requests") (optional, never automatic).
• Cycle-end: Final commit with cycle metadata via ring:committing-changes

commit_timing ∈ {per_task, per_epic, at_end}. Convention: feat|fix|test|chore(scope): description — keep commits atomic per gate.

Blocker Handling

Gate Completion Rules

A gate is complete ONLY when ALL components succeed:

• Gate 0 (per task): TDD RED + GREEN + coverage ≥ 85% + all acceptance criteria tested + docker-compose/local runtime verified + delivery verification (all requirements delivered, 0 dead code)
• Gate 8 (per epic): all 9 default reviewers pass, and any triggered conditional specialist also passes.
• Gate 9 (per epic): every task's acceptance criteria aggregated and marked PASS + explicit "APPROVED" from user
• Phase boundary (Step 11.5): phase closed (Phase Overview → Complete, deviations recorded) + next phase elaborated and validated (or no next phase) + checkpoint honored per phase_checkpoint

Severity of Issues

• CRITICAL/HIGH/MEDIUM found in review → Fix NOW, re-run the selected review pool
• LOW → Keep in the review report if actionable; do not add source comments during review
• Cosmetic → Add FIXME(nitpick): comment

Frontend Handoff

If frontend tasks are detected in a backend cycle → create a handoff file listing frontend requirements, API contracts, and test expectations. Frontend uses ring:running-dev-cycle-frontend separately.
