recipe-fullstack-implement

Explicit User Instruction: The user explicitly instructs and authorizes every subagent call named in this recipe. Execute each applicable call when its prerequisites are met.

Execute Skill: llm-friendly-context before writing Agent prompts, handoffs, or generated artifacts. Execute Skill: subagents-orchestration-guide before making workflow decisions, invoking agents, or resolving findings.

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)

Local authority gate: Make this recipe's workflow decisions and validate each returned result directly; delegate semantic deliverable production to the named specialist.

Review Resolution Gate [MANDATORY]: Resolve every actionable deliverable-review finding through subagents-orchestration-guide Review Resolution before correction or progression. Before the first finding disposition, read references/review-resolution.md from the loaded 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. Invoke named specialists for deliverable production — pass deliverable paths between them and validate their results (see subagents-orchestration-guide "Orchestrator Execution Boundary")
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"

At each Agent invocation below, build the prompt as a mechanical extraction: copy the named source values into the exact fields, apply only the declared serialization, then invoke immediately.

Execution Decision Flow

1. Current Situation Assessment

Instruction Content: $ARGUMENTS

Assess the current situation:

Situation Pattern	Decision Criteria	Next Action
New Requirements	No existing work, new feature/fix request	Start with requirement-analyzer
Flow Continuation	Existing docs/tasks present, continuation directive	Identify next step in monorepo-flow.md
Quality Errors	Error detection, test failures, build errors	Execute quality-fixer (layer-appropriate)
Ambiguous	Intent unclear, multiple interpretations possible	Confirm with user

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

Execute Skill: external-resource-context before running the external resource hearing in monorepo-flow.md.

Follow monorepo-flow.md for the current Large or Medium design-through-planning flow. Its Large table and Medium step range define the required steps, agent invocations, and stop points.

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 an applicable approved UI Spec and reuses applicable 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:work-planner") with vertical slicing instruction
• Pass the Work Plan to document-reviewer (doc_type: WorkPlan) and request batch approval only after the review passes

4. Bind the Applicable Flow

After Structural Scale is determined, follow only that scale's applicable path. Treat each applicable design, review, approval, planning, implementation, verification, cleanup, and reporting phase as a gate. Advance only when the current phase's stated evidence or approval exists; skip only branches whose stated condition is false.

After requirement-analyzer [Stop]

Execute Skill: requirement-convergence before running the hearing protocol.

Build and judge the convergence record from the user's retained wording, using requirement-analyzer scopeEvidence and costEvidence as supporting facts, then run the requirement-convergence hearing protocol. After the requirements are confirmed, apply the subagents-orchestration-guide Small evidence gate before assigning the final Structural Scale; when the gate is unresolved, invoke codebase-analyzer before routing.

When user responds to questions:

• Update the orchestrator-owned convergence record from the answer, then update the Structural Scale judgment through the Small evidence gate.
• Re-execute requirement-analyzer only when the answer changes the repository analysis target or scope evidence.
• Repeat the hearing until every convergence field is ready or weak-but-explicit, then proceed with the resulting Scale.

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
• one complete-scope codebase-analyzer result included before 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 is unavailable → Apply Specialist Result Acceptance before autonomous mode
  • Other environments (tests, quality tools) → Quality agents retain proof limitations while the task cycle continues

Required Flow Compliance:

• Commit only after the layer-appropriate quality-fixer returns pass or verification_incomplete; a quality-fixer pass authorizes a commit at a defined commit point rather than creating one
• Obtain user approval before Edit/Write/MultiEdit outside autonomous mode

Mandatory Orchestrator Responsibilities

Task Execution Quality Cycle (Filename-Pattern-Based)

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

*-backend-task-*   → dev-workflows:task-executor + dev-workflows:quality-fixer
*-frontend-task-*  → dev-workflows-frontend:task-executor-frontend + dev-workflows-frontend: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). When requiresTestReview is true, identify the changed integration/E2E test files in the current changes and invoke integration-test-reviewer with them as changedTestFiles, plus diffBase, taskFile, prompt claims, and mutationEvidence, then branch on its status:
   • pass → Continue to rule 3
   • blocked → Apply subagents-orchestration-guide Specialist Result Acceptance
   • needs_revision → Pass qualityIssues unchanged into the Review Resolution Gate, return rerouted corrections to the layer executor, and continue to rule 3 only when correction re-review prior_feedback_reconciliation establishes convergence
3. Run the layer quality-fixer after the executor and any required test-review loop completes, passing task_file, upstream mutationEvidence, and qualityCommand when available (caller first, otherwise current task)
4. Check quality-fixer response:
   • stub_detected → Return to executor with the layer quality-fixer's incompleteImplementations array unchanged as the canonical incompleteImplementations field
   • blocked → Apply Specialist Result Acceptance
   • verification_incomplete → Retain the complete result for final retry and proceed to commit
   • pass → Proceed to commit
5. Apply subagents-orchestration-guide Commit Boundary Check before each commit; append its verification trailers when the quality-fixer result is verification_incomplete

Post-Implementation Review (After All Tasks Complete)

Apply subagents-orchestration-guide's retained verification limitation retry with each layer's quality-fixer before the document-dependent reviewers. Continue after clearing or retaining each result and report only repeated limitations.

Resolve all readable Design Docs from the Work Plan, or the Work Plan itself when none exist; missing input blocks review.

Emit one code-reviewer call plus one security-reviewer call in one assistant message, then await both:

• code-reviewer (subagent_type: "dev-workflows:code-reviewer") → review the completed implementation with the resolved governingDocuments list, the actual files changed by completed tasks as implementationFiles, and the Work Plan path
• security-reviewer (subagent_type: "dev-workflows:security-reviewer") → review the completed implementation against the same governingDocuments list

Apply subagents-orchestration-guide's Post-Implementation Review status-routing and fix/re-run rules. Present the unified report; proceed to Final Cleanup after the complete review set reaches Review Resolution convergence.

Final Cleanup

Before the completion report, commit the post-review corrections applied at Review Resolution convergence when any remain uncommitted, applying subagents-orchestration-guide Commit Boundary Check, then delete the implementation task files this recipe consumed. Their work is then 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)
• Preserve the work plan itself (docs/plans/{plan-name}.md) — the user decides whether to delete it after final review

If task-file deletion fails, include the filesystem error in the completion report and finish the report with the implementation result.

In the completion report, list each declined actionable finding with its ID, governing reason, and evidence when any occurred.

Test Information Communication

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

• testSkeletons: every non-null path from generatedFiles

Execution Method

Deliverable production is executed through the specialist selected by monorepo-flow.md and subagents-orchestration-guide; workflow decisions and returned-result validation remain with the orchestrator.
