marsai:dev-cycle-frontend

Frontend Development Cycle Orchestrator

Standards Loading (MANDATORY)

Before any gate execution, you MUST load MarsAI standards:

<fetch_required> https://raw.githubusercontent.com/V4-Company/marsai/main/CLAUDE.md https://raw.githubusercontent.com/V4-Company/marsai/main/dev-team/docs/standards/frontend.md </fetch_required>

Fetch URLs above and extract: Agent Modification Verification requirements, Anti-Rationalization Tables requirements, Critical Rules, and Frontend Standards.

<block_condition>

• WebFetch fails or returns empty
• CLAUDE.md not accessible
• frontend.md not accessible </block_condition>

If any condition is true, STOP and report blocker. Cannot proceed without MarsAI standards.

Overview

The frontend development cycle orchestrator loads tasks/subtasks from PM team output (or manual task files) and executes through 9 gates (Gate 0-8) with all gates executing per unit (no deferred execution):

• Gates 0-8 (per unit): Write code + run tests/checks per task/subtask
• All 9 gates are sequential and mandatory

Unlike the backend marsai:dev-cycle (which defers integration/chaos test execution), the frontend cycle executes all gates fully per unit. Frontend testing tools (Playwright, Storybook, Lighthouse) do not require heavy container infrastructure.

MUST announce at start: "I'm using the marsai:dev-cycle-frontend skill to orchestrate frontend task execution through 9 gates (Gate 0-8). All gates execute per unit."

CRITICAL: Specialized Agents Perform All Tasks

See shared-patterns/shared-orchestrator-principle.md for full ORCHESTRATOR principle, role separation, forbidden/required actions, gate-to-agent mapping, and anti-rationalization table.

Summary: You orchestrate. Agents execute. If using Read/Write/Edit/Bash on source code, STOP. Dispatch agent.

ORCHESTRATOR BOUNDARIES (HARD GATE)

This section defines exactly what the orchestrator CAN and CANNOT do.

What Orchestrator CAN Do (PERMITTED)

Action	Tool	Purpose
Read task files	Read	Load task definitions from docs/pre-dev/*/tasks-frontend.md or docs/pre-dev/*/tasks.md
Read state files	Read	Load/verify docs/marsai:dev-cycle-frontend/current-cycle.json
Read PROJECT_RULES.md	Read	Load project-specific rules
Read backend handoff	Read	Load docs/marsai:dev-cycle/handoff-frontend.json if available
Write state files	Write	Persist cycle state to JSON
Track progress	TodoWrite	Maintain task list
Dispatch agents	Task	Send work to specialist agents
Ask user questions	AskUserQuestion	Get execution mode, approvals
WebFetch standards	WebFetch	Load MarsAI standards

What Orchestrator CANNOT Do (FORBIDDEN)

- Read source code (`Read` on `*.ts`, `*.tsx`, `*.jsx`, `*.css`, `*.scss`) - Agent reads code, not orchestrator - Write source code (`Write`/`Create` on `*.ts`, `*.tsx`, `*.jsx`) - Agent writes code, not orchestrator - Edit source code (`Edit` on `*.ts`, `*.tsx`, `*.jsx`, `*.css`) - Agent edits code, not orchestrator - Run tests (`Execute` with `npm test`, `npx playwright`, `npx vitest`) - Agent runs tests in TDD cycle - Analyze code (Direct pattern analysis) - `marsai:codebase-explorer` analyzes - Make architectural decisions (Choosing patterns/libraries) - User decides, agent implements

Any of these actions by orchestrator = IMMEDIATE VIOLATION. Dispatch agent instead.

---

The 3-FILE RULE

If a task requires editing MORE than 3 files, MUST dispatch specialist agent.

This is not negotiable:

• 1-3 files of non-source content (markdown, json, yaml) - Orchestrator MAY edit directly
• 1+ source code files (*.ts, *.tsx, *.jsx, *.css) - MUST dispatch agent
• 4+ files of any type - MUST dispatch agent

Orchestrator Workflow Order (MANDATORY)

+------------------------------------------------------------------+
|  CORRECT WORKFLOW ORDER                                           |
+------------------------------------------------------------------+
|                                                                   |
|  1. Load task file (Read docs/pre-dev/*/tasks-frontend.md)        |
|  2. Detect UI library mode (Step 0)                               |
|  3. Load backend handoff if available                             |
|  4. Ask execution mode (AskUserQuestion)                          |
|  5. Determine state path + Check/Load state                       |
|  6. WebFetch MarsAI Standards (CLAUDE.md + frontend.md)             |
|  7. LOAD SUB-SKILL for current gate (Skill tool)                  |
|  8. Execute sub-skill instructions (dispatch agent via Task)      |
|  9. Wait for agent completion                                     |
|  10. Verify agent output (Standards Coverage Table)               |
|  11. Update state (Write to JSON)                                 |
|  12. Proceed to next gate                                         |
|                                                                   |
|  ================================================================ |
|  WRONG: Load -> Mode -> Standards -> Task(agent) directly         |
|  RIGHT: Load -> Mode -> Standards -> Skill(sub) -> Task(agent)    |
|  ================================================================ |
+------------------------------------------------------------------+

---

UI Library Mode Detection (MANDATORY - Step 0)

Before any gate execution, detect the project's UI library configuration:

Read tool: package.json

Parse the JSON content:
  - If "dependencies" or "devDependencies" contains "@V4-Company/sindarian-ui"
    → ui_library_mode = "sindarian-ui"
  - Otherwise
    → ui_library_mode = "fallback-only"

Store result in state file under ui_library_mode.

@V4-Company/sindarian-ui is PRIMARY. shadcn/ui + Radix is FALLBACK for missing components.

Mode	Meaning	Agent Behavior
sindarian-ui	Sindarian UI detected in package.json	Use Sindarian components first, shadcn/ui only for gaps
fallback-only	No Sindarian UI detected	Use shadcn/ui + Radix as primary component library

Anti-Rationalization for UI Library Mode:

Rationalization	Why It's WRONG	Required Action
"Skip detection, just use shadcn"	Project may have Sindarian UI. Skipping = wrong components.	MUST detect before Gate 0
"Mode doesn't matter for this task"	Mode affects every component decision in Gate 0.	MUST detect and store in state

---

Backend Handoff Loading (Optional)

If the frontend cycle follows a backend marsai:dev-cycle, load the handoff file:

Check: Does docs/marsai:dev-cycle/handoff-frontend.json exist?

  YES -> Load and parse:
    - endpoints: API endpoints implemented by backend
    - types: TypeScript types/interfaces exported by backend
    - contracts: Request/response schemas
    - auth_pattern: Authentication approach (JWT, session, etc.)
    Store in state.backend_handoff

  NO -> Proceed without handoff (standalone frontend development)

Handoff contents are CONTEXT for agents, not requirements. Agents MUST still follow all gate requirements regardless of handoff content.

---

SUB-SKILL LOADING IS MANDATORY (HARD GATE)

Before dispatching any agent, you MUST load the corresponding sub-skill first.

<cannot_skip>

• Gate 0: Skill("marsai:dev-implementation") → then Task(subagent_type="marsai:frontend-engineer" or "marsai:ui-engineer" or "marsai:frontend-bff-engineer-typescript")
• Gate 1: Skill("marsai:dev-devops") → then Task(subagent_type="marsai:devops-engineer")
• Gate 2: Skill("marsai:dev-frontend-accessibility") → then Task(subagent_type="marsai:qa-analyst-frontend", test_mode="accessibility")
• Gate 3: Skill("marsai:dev-unit-testing") → then Task(subagent_type="marsai:qa-analyst-frontend", test_mode="unit")
• Gate 4: Skill("marsai:dev-frontend-visual") → then Task(subagent_type="marsai:qa-analyst-frontend", test_mode="visual")
• Gate 5: Skill("marsai:dev-frontend-e2e") → then Task(subagent_type="marsai:qa-analyst-frontend", test_mode="e2e")
• Gate 6: Skill("marsai:dev-frontend-performance") → then Task(subagent_type="marsai:qa-analyst-frontend", test_mode="performance")
• Gate 7: Skill("marsai:requesting-code-review") → then 5x Task(...) in parallel
• Gate 8: Skill("marsai:dev-validation") → N/A (verification only) </cannot_skip>

Between "WebFetch standards" and "Task(agent)" there MUST be "Skill(sub-skill)".

The workflow for each gate is:

1. Skill("[sub-skill-name]")     <- Load sub-skill instructions
2. Follow sub-skill instructions  <- Sub-skill tells you HOW to dispatch
3. Task(subagent_type=...)       <- Dispatch agent as sub-skill instructs
4. Validate agent output          <- Per sub-skill validation rules
5. Update state                   <- Record results

Custom Instructions (Optional Second Argument)

Validation: See shared-patterns/custom-prompt-validation.md for max length (500 chars), sanitization rules, gate protection, and conflict handling.

If custom_prompt is set in state, inject it into all agent dispatches:

Task tool:
  subagent_type: "marsai:frontend-engineer"
  prompt: |
    **CUSTOM CONTEXT (from user):**
    {state.custom_prompt}

    ---

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

Rules for custom prompt:

1. Inject at TOP of prompt - User context takes precedence
2. Preserve in state - custom_prompt persists for resume
3. Include in execution report - Document what context was used
4. Forward via state - Sub-skills read custom_prompt from state file and inject into their agent dispatches (no explicit parameter passing needed)

Example custom prompts and their effect:

Custom Prompt	Effect on Agents
"Use dark mode as default theme"	Agents implement dark mode first, light as secondary
"Focus on mobile-first responsive design"	Gate 4 visual tests prioritize mobile breakpoints
"Integrate with existing auth context from backend"	Gate 0 uses backend handoff auth pattern
"Prioritize accessibility over animations"	Gate 2 gets more attention, animations simplified

Anti-Rationalization for Skipping Sub-Skills

Rationalization	Why It's WRONG	Required Action
"I know what the sub-skill does"	Knowledge ≠ execution. Sub-skill has iteration logic.	Load Skill() first
"Task() directly is faster"	Faster ≠ correct. Sub-skill has validation rules.	Load Skill() first
"Sub-skill just wraps Task()"	Sub-skills have retry logic, fix dispatch, validation.	Load Skill() first
"I'll follow the pattern manually"	Manual = error-prone. Sub-skill is the pattern.	Load Skill() first

Between "WebFetch standards" and "Task(agent)" there MUST be "Skill(sub-skill)".

---

Anti-Rationalization for Direct Coding

Rationalization	Why It's WRONG	Required Action
"It's just one small component"	File count doesn't determine agent need. Standards do.	DISPATCH specialist agent
"I already loaded the standards"	Loading standards ≠ permission to implement. Standards are for AGENTS.	DISPATCH specialist agent
"Agent dispatch adds overhead"	Overhead ensures compliance. Skip = skip verification.	DISPATCH specialist agent
"I can write React/TypeScript"	Knowing framework ≠ having MarsAI standards loaded. Agent has them.	DISPATCH specialist agent
"Just a quick CSS fix"	"Quick" is irrelevant. All source changes require specialist.	DISPATCH specialist agent
"I'll read the component first to understand"	Reading source = temptation to edit. Agent reads for you.	DISPATCH specialist agent
"Let me check if tests pass first"	Agent runs tests in TDD cycle. You don't run tests.	DISPATCH specialist agent

Red Flags - Orchestrator Violation in Progress

If you catch yourself doing any of these, STOP IMMEDIATELY:

RED FLAG: About to Read *.tsx or *.ts file
   -> STOP. Dispatch agent instead.

RED FLAG: About to Write/Create source code
   -> STOP. Dispatch agent instead.

RED FLAG: About to Edit source code or CSS
   -> STOP. Dispatch agent instead.

RED FLAG: About to run "npm test" or "npx playwright test"
   -> STOP. Agent runs tests, not you.

RED FLAG: Thinking "I'll just..."
   -> STOP. "Just" is the warning word. Dispatch agent.

RED FLAG: Thinking "This is simple enough..."
   -> STOP. Simplicity is irrelevant. Dispatch agent.

RED FLAG: Standards loaded, but next action is not Task tool
   -> STOP. After standards, IMMEDIATELY dispatch agent.

Recovery from Orchestrator Violation

If you violated orchestrator boundaries:

1. STOP current execution immediately
2. DISCARD any direct changes (git checkout -- .)
3. DISPATCH the correct specialist agent
4. Agent implements from scratch following TDD
5. Document the violation for feedback loop

Sunk cost of direct work is IRRELEVANT. Agent dispatch is MANDATORY.

---

Blocker Criteria - STOP and Report

<block_condition>

• Gate Failure: Tests not passing, review failed -> STOP, cannot proceed to next gate
• Missing Standards: No PROJECT_RULES.md -> STOP, report blocker and wait
• Agent Failure: Specialist agent returned errors -> STOP, diagnose and report
• User Decision Required: Component library choice, design system variance -> STOP, present options
• Accessibility Blocker: WCAG AA violations found -> STOP, fix before proceeding </block_condition>

You CANNOT proceed when blocked. Report and wait for resolution.

Cannot Be Overridden

<cannot_skip>

• All 9 gates must execute (0->1->2->3->4->5->6->7->8) - Each gate catches different issues
• All testing gates (2-6) are MANDATORY - Comprehensive test coverage ensures quality
• Gates execute in order (0->1->2->3->4->5->6->7->8) - Dependencies exist between gates
• Gate 7 requires all 5 reviewers - Different review perspectives are complementary
• Unit test coverage threshold >= 85% - Industry standard for quality code
• WCAG 2.1 AA compliance is non-negotiable - Accessibility is a legal requirement
• Core Web Vitals thresholds are non-negotiable - Performance affects user experience
• PROJECT_RULES.md must exist - Cannot verify standards without target </cannot_skip>

No exceptions. User cannot override. Time pressure cannot override.

---

Severity Calibration

Severity	Criteria	Examples
CRITICAL	Blocks deployment, accessibility violation, security risk	Gate violation, WCAG AA failure, XSS vulnerability
HIGH	Major functionality broken, standards violation	Missing tests, wrong agent dispatched, performance regression
MEDIUM	Code quality, maintainability issues	Incomplete documentation, minor gaps, non-ideal patterns
LOW	Best practices, optimization	Style improvements, minor refactoring, cosmetic issues

Report all severities. Let user prioritize.

Reviewer Verdicts Are Final

MEDIUM issues found in Gate 7 MUST be fixed. No exceptions.

Request	Why It's WRONG	Required Action
"Can reviewer clarify if MEDIUM can defer?"	Reviewer already decided. MEDIUM means FIX.	Fix the issue, re-run reviewers
"Ask if this specific case is different"	Reviewer verdict accounts for context already.	Fix the issue, re-run reviewers
"Request exception for business reasons"	Reviewers know business context. Verdict is final.	Fix the issue, re-run reviewers

Severity mapping is absolute:

• CRITICAL/HIGH/MEDIUM -> Fix NOW, re-run all 5 reviewers
• LOW -> Add TODO(review): comment
• Cosmetic -> Add FIXME(nitpick): comment

No negotiation. No exceptions. No "special cases".

The 9 Gates

Gate	Skill	Purpose	Agent	Standards Module
0	marsai:dev-implementation	Write code following TDD	marsai:frontend-engineer / marsai:ui-engineer / marsai:frontend-bff-engineer-typescript	frontend.md
1	marsai:dev-devops	Docker/compose/Nginx setup	marsai:devops-engineer	devops.md
2	marsai:dev-frontend-accessibility	WCAG 2.1 AA compliance	marsai:qa-analyst-frontend (test_mode: accessibility)	testing-accessibility.md
3	marsai:dev-unit-testing	Unit tests 85%+ coverage	marsai:qa-analyst-frontend (test_mode: unit)	frontend.md
4	marsai:dev-frontend-visual	Snapshot/visual regression tests	marsai:qa-analyst-frontend (test_mode: visual)	testing-visual.md
5	marsai:dev-frontend-e2e	E2E tests with Playwright	marsai:qa-analyst-frontend (test_mode: e2e)	testing-e2e.md
6	marsai:dev-frontend-performance	Core Web Vitals + Lighthouse	marsai:qa-analyst-frontend (test_mode: performance)	testing-performance.md
7	marsai:requesting-code-review	Parallel code review (5 reviewers)	marsai:code-reviewer, marsai:business-logic-reviewer, marsai:security-reviewer, marsai:test-reviewer, marsai:frontend-engineer (review mode)	N/A
8	marsai:dev-validation	Final acceptance validation	N/A (verification)	N/A

All gates are MANDATORY. No exceptions. No skip reasons.

Gate 0: Agent Selection Logic

Condition	Agent to Dispatch
React/Next.js component implementation	marsai:frontend-engineer
Design system / Sindarian UI component	marsai:ui-engineer
BFF / API aggregation layer	marsai:frontend-bff-engineer-typescript
Mixed (component + BFF)	Dispatch marsai:frontend-engineer first, then marsai:frontend-bff-engineer-typescript

UI library mode (detected in Step 0) MUST be passed to the agent as context.

Gate 0: Frontend TDD Policy

TDD (RED→GREEN) applies to behavioral logic. Visual/presentational components use test-after.

Component Layer	TDD Required?	Where Tests Are Created	Rationale
Custom hooks	YES - TDD RED→GREEN	Gate 0 (implementation)	Test defines the hook contract before code
Form validation	YES - TDD RED→GREEN	Gate 0 (implementation)	Test defines validation rules before code
State management	YES - TDD RED→GREEN	Gate 0 (implementation)	Test defines state transitions before code
Conditional rendering	YES - TDD RED→GREEN	Gate 0 (implementation)	Test defines when elements show/hide
API integration / data fetching	YES - TDD RED→GREEN	Gate 0 (implementation)	Test defines expected request/response
Layout / styling	NO - test-after	Gate 4 (visual testing)	Visual output is exploratory; snapshot locks it
Animations / transitions	NO - test-after	Gate 4 (visual testing)	Motion is iterative; test captures final state
Static presentational components	NO - test-after	Gate 4 (visual testing)	No logic to drive with RED phase

Rules:

1. Behavioral components in Gate 0 MUST produce TDD RED failure output before implementation
2. Visual/presentational components in Gate 0 are implemented without RED phase; Gate 4 creates their snapshot tests
3. Mixed components (behavior + visual): TDD for the behavioral part, test-after for the visual part
4. Gate 3 (Unit Testing) coverage threshold (85%) still applies to ALL component types - the distinction is only about WHEN tests are written, not WHETHER

Anti-Rationalization:

Rationalization	Why It's WRONG	Required Action
"This hook is simple, skip TDD"	Simple hooks still need contract verification.	TDD RED→GREEN for all hooks
"Form validation is visual"	Validation rules are logic, not presentation.	TDD RED→GREEN for validation
"This component has onClick, skip TDD"	Event handlers contain logic. TDD for the handler behavior.	TDD RED→GREEN for behavioral logic
"Layout needs TDD too"	Snapshot test written before layout exists is meaningless.	Test-after in Gate 4
"Skip all tests, Gate 4 handles it"	Gate 4 covers visual snapshots only. Behavioral tests are Gate 0+3.	TDD for behavior in Gate 0

Gate 7: Code Review Adaptation (5 Reviewers)

For the frontend cycle, the 5 parallel reviewers are:

#	Reviewer	Focus Area
1	marsai:code-reviewer	Code quality, patterns, maintainability, React best practices
2	marsai:business-logic-reviewer	Business logic correctness, domain rules, acceptance criteria
3	marsai:security-reviewer	XSS, CSRF, auth handling, sensitive data exposure, CSP
4	marsai:test-reviewer	Test quality, coverage gaps, test patterns, assertion quality
5	marsai:frontend-engineer (review mode)	Accessibility compliance, frontend standards, component architecture

NOTE: The 5th reviewer slot uses marsai:frontend-engineer in review mode instead of marsai:nil-safety-reviewer. The frontend engineer reviews accessibility compliance and frontend standards adherence.

All 5 reviewers MUST be dispatched in a single message with 5 parallel Task calls.

# Gate 7: Dispatch all 5 reviewers in parallel (SINGLE message)
Task 1: { subagent_type: "marsai:code-reviewer", ... }
Task 2: { subagent_type: "marsai:business-logic-reviewer", ... }
Task 3: { subagent_type: "marsai:security-reviewer", ... }
Task 4: { subagent_type: "marsai:test-reviewer", ... }
Task 5: { subagent_type: "marsai:frontend-engineer", prompt: "REVIEW MODE: Review accessibility compliance and frontend standards adherence...", ... }

---

Gate Completion Definition (HARD GATE)

A gate is COMPLETE only when all components finish successfully:

Gate	Components Required	Partial = FAIL
0.1	TDD-RED: Failing test written + failure output captured (behavioral components only - see Frontend TDD Policy)	Test exists but no failure output = FAIL. Visual-only components skip to 0.2
0.2	TDD-GREEN: Implementation passes test (behavioral) OR implementation complete (visual)	Code exists but test fails = FAIL
0	Both 0.1 and 0.2 complete (behavioral) OR 0.2 complete (visual - snapshots deferred to Gate 4)	0.1 done without 0.2 = FAIL
1	Dockerfile + docker-compose/nginx + .env.example	Missing any = FAIL
2	0 WCAG AA violations + keyboard navigation tested + screen reader tested	Any violation = FAIL
3	Unit test coverage >= 85% + all AC tested	84% = FAIL
4	All state snapshots pass + responsive breakpoints covered	Missing snapshots = FAIL
5	All user flows tested + cross-browser (Chromium, Firefox, WebKit) + 3x stable pass	Flaky = FAIL
6	LCP < 2.5s + CLS < 0.1 + INP < 200ms + Lighthouse >= 90	Any threshold missed = FAIL
7	All 5 reviewers PASS	4/5 reviewers = FAIL
8	Explicit "APPROVED" from user	"Looks good" = not approved

CRITICAL for Gate 7: Running 4 of 5 reviewers is not a partial pass - it's a FAIL. Re-run all 5 reviewers.

Anti-Rationalization for Partial Gates:

Rationalization	Why It's WRONG	Required Action
"4 of 5 reviewers passed"	Gate 7 requires all 5. 4/5 = 0/5.	Re-run all 5 reviewers
"Gate mostly complete"	Mostly ≠ complete. Binary: done or not done.	Complete all components
"Can finish remaining in next cycle"	Gates don't carry over. Complete NOW.	Finish current gate
"No component is optional within a gate"	Every component is required.	Complete all components
"Accessibility can be fixed later"	WCAG compliance is mandatory NOW. Later = never.	Fix accessibility in Gate 2
"Visual tests are flaky, skip them"	Fix flakiness, don't skip verification.	Stabilize and pass Gate 4
"Lighthouse score is 88, close enough"	Close enough ≠ passing. Threshold is >= 90.	Optimize until threshold met

---

Gate Order Enforcement (HARD GATE)

Gates MUST execute in order: 0 -> 1 -> 2 -> 3 -> 4 -> 5 -> 6 -> 7 -> 8. All 9 gates are MANDATORY.

Violation	Why It's WRONG	Consequence
Skip Gate 1 (DevOps)	"No infra changes"	App without container = works on my machine only
Skip Gate 2 (Accessibility)	"It's internal tool"	Internal tools MUST be accessible. Legal requirement.
Skip Gate 3 (Unit Testing)	"E2E covers it"	E2E is slow, unit tests catch logic bugs faster
Skip Gate 4 (Visual)	"Snapshots are brittle"	Fix brittleness, don't skip regression detection
Skip Gate 5 (E2E)	"Manual testing done"	Manual testing is not reproducible or automated
Skip Gate 6 (Performance)	"Optimize later"	Later = never. Performance budgets apply NOW
Reorder Gates	"Review before test"	Reviewing untested code wastes reviewer time
Parallel Gates	"Run 2 and 3 together"	Dependencies exist. Order is intentional.

All testing gates (2-6) are MANDATORY. No exceptions. No skip reasons.

Gates are not parallelizable across different gates. Sequential execution is MANDATORY.

---

Execution Order

Core Principle: Each execution unit passes through all 9 gates. All gates execute and complete per unit.

Per-Unit Flow: Unit -> Gate 0->1->2->3->4->5->6->7->8 -> Unit Checkpoint -> Task Checkpoint -> Next Unit

Scenario	Execution Unit	Gates Per Unit
Task without subtasks	Task itself	9 gates
Task with subtasks	Each subtask	9 gates per subtask

Commit Timing

User selects when commits happen (during initialization).

Option	When Commit Happens	Use Case
(a) Per subtask	After each subtask passes Gate 8	Fine-grained history, easy rollback per subtask
(b) Per task	After all subtasks of a task complete	Logical grouping, one commit per feature chunk
(c) At the end	After entire cycle completes	Single commit with all changes, clean history

Commit Message Format

Timing	Message Format	Example
Per subtask	feat({subtask_id}): {subtask_title}	feat(ST-001-02): implement transaction list component
Per task	feat({task_id}): {task_title}	feat(T-001): implement dashboard page
At the end	feat({cycle_id}): complete frontend dev cycle for {feature}	feat(cycle-abc123): complete frontend dev cycle for dashboard

Commit Timing vs Execution Mode

Execution Mode	Commit Timing	Behavior
Manual per subtask	Per subtask	Commit + checkpoint after each subtask
Manual per subtask	Per task	Checkpoint after subtask, commit after task
Manual per subtask	At end	Checkpoint after subtask, commit at cycle end
Manual per task	Per subtask	Commit after subtask, checkpoint after task
Manual per task	Per task	Commit + checkpoint after task
Manual per task	At end	Checkpoint after task, commit at cycle end
Automatic	Per subtask	Commit after each subtask, no checkpoints
Automatic	Per task	Commit after task, no checkpoints
Automatic	At end	Single commit at cycle end, no checkpoints

Note: Checkpoints (user approval pauses) are controlled by execution_mode. Commits are controlled by commit_timing. They are independent settings.

Populating Structured Data

Each gate MUST populate its structured fields when saving to state:

Gate	Fields to Populate
Gate 0 (Implementation)	standards_compliance (total, compliant, gaps[])
Gate 1 (DevOps)	standards_compliance + verification_errors[]
Gate 2 (Accessibility)	wcag_violations + keyboard_nav_issues + screen_reader_issues
Gate 3 (Unit Testing)	standards_compliance + coverage_actual + failures[]
Gate 4 (Visual Testing)	snapshots_total + snapshots_passed + responsive_breakpoints_covered[]
Gate 5 (E2E Testing)	flows_tested + browsers_tested[] + stability_runs
Gate 6 (Performance)	lcp_ms + cls + inp_ms + lighthouse_score
Gate 7 (Review)	issues[] per reviewer + verdict per reviewer

Empty arrays [] indicate no issues found - this is valid data for feedback-loop.

---

State Persistence Rule (MANDATORY)

"Update state" means BOTH update the object and write to file. Not just in-memory.

After every Gate Transition

You MUST execute these steps after completing any gate:

# Step 1: Update state object with gate results
state.tasks[current_task_index].gate_progress.[gate_name].status = "completed"
state.tasks[current_task_index].gate_progress.[gate_name].completed_at = "[ISO timestamp]"
state.current_gate = [next_gate_number]
state.updated_at = "[ISO timestamp]"

# Step 2: Write to file (MANDATORY - use Write tool)
Write tool:
  file_path: "docs/marsai:dev-cycle-frontend/current-cycle.json"
  content: [full JSON state]

# Step 3: Verify persistence (MANDATORY - use Read tool)
Read tool:
  file_path: "docs/marsai:dev-cycle-frontend/current-cycle.json"
# Confirm current_gate and gate_progress match expected values

State Persistence Checkpoints

After	MUST Update	MUST Write File
Gate 0.1 (TDD-RED)	tdd_red.status, tdd_red.failure_output	YES
Gate 0.2 (TDD-GREEN)	tdd_green.status, implementation.status	YES
Gate 1 (DevOps)	devops.status, agent_outputs.devops	YES
Gate 2 (Accessibility)	accessibility.status, agent_outputs.accessibility	YES
Gate 3 (Unit Testing)	unit_testing.status, agent_outputs.unit_testing	YES
Gate 4 (Visual Testing)	visual_testing.status, agent_outputs.visual_testing	YES
Gate 5 (E2E Testing)	e2e_testing.status, agent_outputs.e2e_testing	YES
Gate 6 (Performance)	performance_testing.status, agent_outputs.performance_testing	YES
Gate 7 (Review)	review.status, agent_outputs.review	YES
Gate 8 (Validation)	validation.status, task status	YES
Unit Approval	status = "paused_for_approval"	YES
Task Approval	status = "paused_for_task_approval"	YES

Anti-Rationalization for State Persistence

Rationalization	Why It's WRONG	Required Action
"I'll save state at the end"	Crash/timeout loses all progress	Save after each gate
"State is in memory, that's updated"	Memory is volatile. File is persistent.	Write to JSON file
"Only save on checkpoints"	Gates without saves = unrecoverable on resume	Save after every gate
"Write tool is slow"	Write takes <100ms. Lost progress takes hours.	Write after every gate
"I updated the state variable"	Variable ≠ file. Without Write tool, nothing persists.	Use Write tool explicitly

---

Checkpoint Modes

User selects checkpoint mode during initialization.

Mode	Checkpoint Behavior	Gate Behavior
Manual per subtask	Pause after each subtask completes all 9 gates	All 9 gates execute without pause
Manual per task	Pause after all subtasks of a task complete	All 9 gates execute without pause
Automatic	No pauses	All 9 gates execute without pause

CRITICAL: Execution mode affects CHECKPOINTS (user approval pauses), not GATES (quality checks). All gates execute regardless of mode.

Checkpoint Questions

Unit Checkpoint (after subtask completes Gate 8):

VISUAL CHANGE REPORT (MANDATORY - before checkpoint question):

• MANDATORY: Invoke Skill("marsai:visual-explainer") to generate a code-diff HTML report for this execution unit
• Read default/skills/visual-explainer/templates/code-diff.html to absorb the patterns before generating
• Content sourced from state JSON agent_outputs for the current unit:
  • TDD Output: tdd_red (failing test) + tdd_green (implementation)
  • Files Changed: Per-file before/after diff panels using git diff data from the implementation (do not read source files directly — use diff output provided by the implementation agent)
  • Frontend-Specific Metrics: WCAG violations resolved (Gate 2), visual snapshot pass rate (Gate 4), LCP/CLS/INP values (Gate 6), Lighthouse score (Gate 6)
  • Review Verdicts: Summary of all 5 reviewer verdicts from Gate 7
• Save to: docs/marsai:dev-cycle-frontend/reports/unit-{unit_id}-report.html
• Open in browser:

  macOS: open docs/marsai:dev-cycle-frontend/reports/unit-{unit_id}-report.html
  Linux: xdg-open docs/marsai:dev-cycle-frontend/reports/unit-{unit_id}-report.html
  

• Tell the user the file path
• See shared-patterns/anti-rationalization-visual-report.md for anti-rationalization table

Subtask {id} complete. All 9 gates passed.
(a) Continue to next subtask
(b) Pause cycle (save state for --resume)
(c) Abort cycle

Task Checkpoint (after all subtasks of a task complete):

VISUAL CHANGE REPORT (MANDATORY - before task checkpoint question):

• MANDATORY: Invoke Skill("marsai:visual-explainer") to generate an aggregate code-diff HTML report for all subtasks
• Read default/skills/visual-explainer/templates/code-diff.html to absorb the patterns before generating
• Content aggregated from all subtask executions:
  • Task Overview: Task ID, title, all subtask IDs and their gate statuses
  • Combined File Changes: All files modified across all subtasks with before/after diff panels
  • Aggregate Metrics: Total tests added, total review iterations, total lines changed, accessibility score, performance score
• Save to: docs/marsai:dev-cycle-frontend/reports/task-{task_id}-report.html
• Open in browser:

  macOS: open docs/marsai:dev-cycle-frontend/reports/task-{task_id}-report.html
  Linux: xdg-open docs/marsai:dev-cycle-frontend/reports/task-{task_id}-report.html
  

• Tell the user the file path
• See shared-patterns/anti-rationalization-visual-report.md for anti-rationalization table

Task {id} complete. All subtasks passed all gates.
(a) Continue to next task
(b) Pause cycle
(c) Abort cycle

---

Step 0: Verify PROJECT_RULES.md Exists (HARD GATE)

NON-NEGOTIABLE. Cycle CANNOT proceed without project standards.

Same flow as backend marsai:dev-cycle:

Check: Does docs/PROJECT_RULES.md exist?

  YES -> Proceed to Step 1 (Initialize or Resume)

  NO -> ASK: "Is this a LEGACY project?"
    YES (legacy) -> Dispatch marsai:codebase-explorer + ask 3 questions + generate PROJECT_RULES.md
    NO (new) -> Check for PM documents (PRD/TRD/Feature Map)
      HAS PM docs -> Generate PROJECT_RULES.md from PM docs
      NO PM docs -> HARD BLOCK: "Run /marsai:pre-dev-full or /marsai:pre-dev-feature first"

---

Step 1: Initialize or Resume

Prompt-Only Mode (no task file)

Input: Direct prompt without a task file path (e.g., /marsai:dev-cycle-frontend Implement dashboard with transaction list)

1. Detect prompt-only mode: No task file argument provided
2. Analyze prompt: Extract intent, scope, and frontend requirements
3. Explore codebase: Dispatch marsai:codebase-explorer to understand project structure
4. Generate tasks: Create task structure internally based on prompt + codebase analysis
5. Present generated tasks: Show user the auto-generated task breakdown
6. Confirm with user: "I generated X tasks from your prompt. Proceed?"
7. Continue to execution mode selection

New Cycle (with task file path)

Input: path/to/tasks-frontend.md or path/to/pre-dev/{feature}/ with optional second argument for custom instructions

Examples:

• /marsai:dev-cycle-frontend tasks.md
• /marsai:dev-cycle-frontend tasks.md "Use shadcn/ui components"

1. Detect input: File -> Load directly | Directory -> Load tasks-frontend.md + discover subtasks/
2. Build order: Read tasks, check for subtasks (ST-XXX-01, 02...)
3. Detect UI library mode (Step 0 above)
4. Load backend handoff if docs/marsai:dev-cycle/handoff-frontend.json exists
5. Capture and validate custom instructions: If second argument provided
6. Initialize state: Generate cycle_id, create state file, set indices to 0
7. Display plan: "Loaded X tasks with Y subtasks. UI mode: {mode}. Backend handoff: {loaded/not found}."
8. ASK EXECUTION MODE (MANDATORY - AskUserQuestion):
   • Options: (a) Manual per subtask (b) Manual per task (c) Automatic
   • Do not skip: User hints ≠ mode selection. Only explicit a/b/c is valid.
9. ASK COMMIT TIMING (MANDATORY - AskUserQuestion):
   • Options: (a) Per subtask (b) Per task (c) At the end
   • Store in commit_timing field in state
10. Start: Display mode + commit timing, proceed to Gate 0

Resume Cycle (--resume flag)

1. Find existing state file: Check docs/marsai:dev-cycle-frontend/current-cycle.json
   • If not found -> Error: "No frontend cycle to resume"
2. Load state file, validate
3. Display: cycle started, tasks completed/total, current task/subtask/gate, paused reason
4. Handle paused states:

Status	Action
paused_for_approval	Re-present unit checkpoint
paused_for_task_approval	Re-present task checkpoint
paused (generic)	Ask user to confirm resume
in_progress	Resume from current gate

---

Step 2-10: Gate Execution (Per Unit)

Step 2: Gate 0 - Implementation

REQUIRED SUB-SKILL: Skill("marsai:dev-implementation")

Dispatch appropriate frontend agent based on task type. Agent follows TDD (RED then GREEN) with frontend.md standards.

Step 3: Gate 1 - DevOps

REQUIRED SUB-SKILL: Skill("marsai:dev-devops")

Dispatch marsai:devops-engineer for Dockerfile, docker-compose, Nginx configuration, and .env.example.

Step 4: Gate 2 - Accessibility

REQUIRED SUB-SKILL: Skill("marsai:dev-frontend-accessibility")

Dispatch marsai:qa-analyst-frontend with test_mode="accessibility". MUST verify:

• 0 WCAG 2.1 AA violations (axe-core scan)
• Keyboard navigation works for all interactive elements
• Screen reader announcements are correct
• Focus management is proper
• Color contrast ratios meet AA thresholds

Step 5: Gate 3 - Unit Testing

• Coverage >= 85%
• All acceptance criteria have corresponding tests
• Component rendering, state management, and event handlers tested
• Edge cases covered (empty states, error states, loading states)

Step 6: Gate 4 - Visual Testing

REQUIRED SUB-SKILL: Skill("marsai:dev-frontend-visual")

Dispatch marsai:qa-analyst-frontend with test_mode="visual". MUST verify:

• All component states have snapshots (default, hover, active, disabled, error, loading)
• Responsive breakpoints covered (mobile, tablet, desktop)
• Design system compliance verified
• Visual regression baseline established

Step 7: Gate 5 - E2E Testing

REQUIRED SUB-SKILL: Skill("marsai:dev-frontend-e2e")

Dispatch marsai:qa-analyst-frontend with test_mode="e2e". MUST verify:

• All user flows tested end-to-end
• Cross-browser: Chromium, Firefox, WebKit
• 3x consecutive stable pass (no flakiness)
• Page object pattern used for maintainability

Step 8: Gate 6 - Performance Testing

REQUIRED SUB-SKILL: Skill("marsai:dev-frontend-performance")

Dispatch marsai:qa-analyst-frontend with test_mode="performance". MUST verify:

• LCP (Largest Contentful Paint) < 2.5s
• CLS (Cumulative Layout Shift) < 0.1
• INP (Interaction to Next Paint) < 200ms

• Bundle size within budget (if defined in PROJECT_RULES.md)

Step 9: Gate 7 - Code Review

REQUIRED SUB-SKILL: Skill("marsai:requesting-code-review")

Dispatch all 5 reviewers in parallel (see Gate 7: Code Review Adaptation above).

Step 10: Gate 8 - Validation

REQUIRED SUB-SKILL: Skill("marsai:dev-validation")

Present implementation summary to user. Require explicit "APPROVED" response. "Looks good" or silence ≠ approved.

Pressure Resistance

See shared-patterns/shared-pressure-resistance.md for universal pressure scenarios.

Frontend-specific pressure scenarios:

Pressure Type	Request	Agent Response
Accessibility	"Skip accessibility, it's an internal tool"	"FORBIDDEN. Internal tools MUST be accessible. WCAG AA is a legal requirement in many jurisdictions. Gate 2 executes fully."
Browser Coverage	"Only test Chromium, it's the main browser"	"All 3 browsers (Chromium, Firefox, WebKit) are REQUIRED. Cross-browser issues are the most common production bugs."
Performance	"Performance will be optimized later"	"Performance thresholds apply NOW. LCP < 2.5s, CLS < 0.1, INP < 200ms, Lighthouse >= 90. Later = never."
Visual Tests	"Snapshots are too brittle to maintain"	"Fix the brittleness (use threshold tolerances), don't skip regression detection. Gate 4 is MANDATORY."
Design System	"We'll align with design system later"	"Design system compliance is part of Gate 0. Components MUST use Sindarian UI (or shadcn fallback) from the start."

Gate-specific note: Execution mode selection affects CHECKPOINTS (user approval pauses), not GATES (quality checks). All gates execute regardless of mode.

---

Common Rationalizations - REJECTED

See shared-patterns/shared-anti-rationalization.md for universal anti-rationalizations.

Frontend-specific rationalizations:

Excuse	Reality
"Backend already tested this endpoint"	Backend tests verify API logic. Frontend tests verify UI rendering, state management, user interaction, and accessibility. Different concerns entirely.
"Accessibility is optional for MVP"	Accessibility is NEVER optional. WCAG AA compliance is mandatory. Building without it means expensive retrofitting later.
"Snapshots are brittle and slow down development"	Snapshots catch visual regressions that no other test type detects. Fix brittleness with tolerances, don't skip the gate.
"E2E tests are slow, unit tests are enough"	Unit tests verify components in isolation. E2E tests verify user flows end-to-end. Both are MANDATORY because they catch different issues.
"Lighthouse score is close enough at 88"	Close enough ≠ passing. Threshold is >= 90. Optimize bundle size, lazy load, compress images until threshold is met.
"Automatic mode means faster"	Automatic mode skips CHECKPOINTS, not GATES. Same quality, less interruption.
"Only desktop matters, skip mobile testing"	Responsive design is mandatory. Visual tests MUST cover mobile, tablet, and desktop breakpoints.
"This component is reused from design system"	Reused components still need tests in context. Integration point testing is required.

---

Red Flags - STOP

See shared-patterns/shared-red-flags.md for universal red flags.

Frontend-specific red flags:

• "Skip accessibility, we'll add ARIA labels later"
• "Only test happy path in E2E"
• "Performance optimization is a separate ticket"
• "Visual tests will be added when design stabilizes"
• "The designer didn't provide mobile mockups, skip responsive"
• "This browser doesn't matter for our users"
• "It works in Chromium, ship it"

If you catch yourself thinking any of those patterns, STOP immediately and return to gate execution.

---

Incremental Compromise Prevention

The "just this once" pattern leads to complete gate erosion:

Day 1: "Skip accessibility just this once" -> Approved (precedent set)
Day 2: "Skip visual tests, we did it last time" -> Approved (precedent extended)
Day 3: "Skip performance, pattern established" -> Approved (gates meaningless)
Day 4: Production incident: inaccessible UI + layout regression + 5s load time

Prevention rules:

1. No incremental exceptions - Each exception becomes the new baseline
2. Document every pressure - Log who requested, why, outcome
3. Escalate patterns - If same pressure repeats, escalate to team lead
4. Gates are binary - Complete or incomplete. No "mostly done".

---

Input Validation

Task files are generated by /marsai:pre-dev-* or backend handoff. The marsai:dev-cycle-frontend performs basic format checks:

Format Checks

Check	Validation	Action
File exists	Task file path is readable	Error: abort
Task headers	At least one ## Task: found	Error: abort
Task ID format	## Task: {ID} - {Title}	Warning: use line number as ID
Acceptance criteria	At least one - [ ] per task	Warning: task may fail validation gate
