recipe-fullstack-implement-c8d34c— agent skill

Execute Skill: llm-friendly-context before writing Agent prompts, handoffs, or generated artifacts.

Context: Full-cycle fullstack implementation management (Requirements Analysis → Design (backend + frontend) → Planning → Implementation → Quality Assurance)

Orchestrator Definition

Core Identity: "I am an orchestrator." (see subagents-orchestration-guide skill)

Required Reference

MANDATORY: Read references/monorepo-flow.md from subagents-orchestration-guide skill BEFORE proceeding. Follow the Fullstack Flow defined there instead of the standard single-layer flow.

Execution Protocol

1. Delegate all work through Agent tool — invoke sub-agents, pass deliverable paths between them, and report results (permitted tools: see subagents-orchestration-guide "Orchestrator's Permitted Tools")
2. Follow monorepo-flow.md for the design phase (multiple Design Docs, design-sync, vertical slicing)
3. Follow subagents-orchestration-guide skill for all other orchestration rules (stop points, structured responses, escalation)
4. Enter autonomous mode only after "batch approval for entire implementation phase"

CRITICAL: Execute all steps, sub-agents, and stopping points defined in both the monorepo-flow.md reference and subagents-orchestration-guide skill.

Execution Decision Flow

1. Current Situation Assessment

Instruction Content: $ARGUMENTS

Assess the current situation:

2. Progress Verification for Continuation

When continuing existing flow, verify:

• Latest artifacts (PRD/ADR/Design Docs/Work Plan/Tasks)
• Current phase position (Requirements/Design/Planning/Implementation/QA)
• Identify next step in monorepo-flow.md

3. Design through Planning Phase

Follow monorepo-flow.md for the complete design-through-planning flow (Steps 1-16 for Large scale, Steps 1-14 for Medium scale). The flow table in that reference defines every step, agent invocation, parallelization rule, and stop point.

Key points to enforce as the orchestrator runs the flow:

• Create separate Design Docs per layer (see monorepo-flow.md "Layer Context in Design Doc Creation")
• Frontend Design Doc references the approved UI Spec (pass UI Spec path to technical-designer-frontend) and reuses the ui-analyzer output produced earlier in the flow
• Execute document-reviewer once per Design Doc (separate invocations)
• Run design-sync for cross-layer consistency verification
• Pass all Design Docs to work-planner (subagent_type: "dev-workflows-fullstack:work-planner") with vertical slicing instruction

4. Register All Flow Steps Using TaskCreate (MANDATORY)

After scale determination, register all steps of the monorepo-flow.md using TaskCreate:

• First task: "Map preloaded skills to applicable concrete rules"
• Register each step as individual task
• Set currently executing step to in_progress using TaskUpdate
• Complete task registration before invoking subagents

After requirement-analyzer [Stop]

When user responds to questions:

• If response matches any scopeDependencies.question → Check impact for scale change
• If scale changes → Re-execute requirement-analyzer with updated context
• If confidence: "confirmed" or no scale change → Proceed to next step

Subagents Orchestration Guide Compliance Execution

Pre-execution Checklist (MANDATORY):

• [ ] Read monorepo-flow.md reference
• [ ] Confirmed relevant flow steps
• [ ] Identified current progress position
• [ ] Clarified next step
• [ ] Recognized stopping points
• [ ] codebase-analyzer included before each Design Doc creation
• [ ] code-verifier included before document-reviewer for each Design Doc
• [ ] Environment check: Can I execute per-task commit cycle?
• If commit capability unavailable → Escalate before autonomous mode
• Other environments (tests, quality tools) → Subagents will escalate

Required Flow Compliance:

• Run quality-fixer (layer-appropriate) before every commit
• Obtain user approval before Edit/Write/MultiEdit outside autonomous mode

Scope Boundary for Subagents

Append the following block to every subagent prompt invoked from this recipe:

Scope boundary for subagents:
Operate within the task scope and referenced files in the prompt.
Use loaded skills to execute that scope.
Escalate when the required fix or investigation falls outside that scope.

Mandatory Orchestrator Responsibilities

Task Execution Quality Cycle (Filename-Pattern-Based)

Agent routing by task filename (see monorepo-flow.md reference):

*-backend-task-*   → dev-workflows-fullstack:task-executor + dev-workflows-fullstack:quality-fixer
*-frontend-task-*  → dev-workflows-fullstack:task-executor-frontend + dev-workflows-fullstack:quality-fixer-frontend

Rules:

1. Execute ONE task completely before starting next (each task goes through the full 4-step cycle via Agent tool, using the correct executor per filename pattern)
2. Check executor status before quality-fixer (escalation check)
3. Quality-fixer MUST run after each executor before proceeding to commit. Always pass the current task file path as task_file
4. Check quality-fixer response:

• stub_detected → Return to executor with incompleteImplementations[] details
• blocked → Escalate to user
• approved → Proceed to commit

Post-Implementation Verification (After All Tasks Complete)

After all task cycles finish, run verification agents in parallel before the completion report:

1. Invoke both in parallel using Agent tool:

• code-verifier (subagent_type: "dev-workflows-fullstack:code-verifier") → invoke once per Design Doc (doc_type: design-doc, single document_path, code_paths: implementation file list from git diff --name-only main...HEAD)
• security-reviewer (subagent_type: "dev-workflows-fullstack:security-reviewer") → Design Doc path(s), implementation file list

1. Consolidate results — check pass/fail for each:

• code-verifier: pass when status is consistent or mostly_consistent. fail when needs_review or inconsistent. Collect discrepancies with status drift, conflict, or gap
• security-reviewer: pass when status is approved or approved_with_notes. fail when needs_revision. blocked → Escalate to user
• Present unified verification report to user

1. Fix cycle (when any verifier failed):

• Consolidate all actionable findings into a single task file
• Execute layer-appropriate task-executor with consolidated fixes → quality-fixer
• Re-run only the failed verifiers (by the criteria in step 2)
• Repeat until all pass or blocked → Escalate to user

1. All passed → Proceed to Final Cleanup

Final Cleanup

Before the completion report, delete the implementation task files this recipe consumed. Their work is committed; docs/plans/ is ephemeral working state and is not retained between recipe runs:

• Delete every file matching docs/plans/tasks/{plan-name}-backend-task-*.md and docs/plans/tasks/{plan-name}-frontend-task-*.md (the {plan-name} derived from the work plan path used in this run)
• Delete every file matching docs/plans/tasks/{plan-name}-phase*-completion.md (the per-phase completion files generated by task-decomposer)
• Delete the corresponding docs/plans/tasks/_overview-{plan-name}.md if present
• Preserve the work plan itself (docs/plans/{plan-name}.md) — the user decides whether to delete it after final review

If task files cannot be deleted (filesystem error), report the failure but do not block the completion report.

Test Information Communication

After acceptance-test-generator execution, when invoking work-planner (subagent_type: "dev-workflows-fullstack:work-planner"), communicate:

• Generated integration test file path (from generatedFiles.integration)
• Generated fixture-e2e test file path or null (from generatedFiles.fixtureE2e)
• Generated service-integration-e2e test file path or null (from generatedFiles.serviceE2e)
• Per-lane E2E absence reason (from e2eAbsenceReason.fixtureE2e and e2eAbsenceReason.serviceE2e, when each lane is null)
• Explicit note: integration tests are created simultaneously with implementation, fixture-e2e tests are created alongside the UI feature phase, service-integration-e2e tests are executed only in the final phase

Execution Method

All work is executed through sub-agents. Sub-agent selection follows monorepo-flow.md reference and subagents-orchestration-guide skill.
