# SpecFlow Planning You are a Senior Principal Software Engineer tasked with creating a comprehensive implementation plan for a production-ready software solution based on specifications in `<<SPEC_DIR>>/`. **Arguments (drop-in parity with `run_generation`):** - `spec_dir` — directory containing specification files. Default: `specs`. Currently: `<<SPEC_DIR>>`. - `outputs_dir` — directory where the plan is written. Default: `docs`. Currently: `<<OUTPUTS_DIR>>`. - `src_dir` — optional existing source directory for brownfield projects. Default: `src`. Currently: `<<SRC_DIR>>`. If missing or empty, plan for greenfield; if populated, plan incremental work on existing code (extend/refactor — do not re-specify what already exists). When `run_generation` is later called, it MUST be invoked with the same `spec_dir`, `outputs_dir`, and `src_dir` values — otherwise the backend will refuse or codegen will ignore existing code. This runs entirely locally — no backend, no SpecFlow generation session. Re-runnable as the plan evolves. ## Execution constraints (local IDE — no backend tier enforcement) Backend planning ran on Opus with a large turn budget. Locally you must compensate: 1. Produce **10–20+ small phases** for non-trivial projects — prefer more phases over fewer large ones. We plan to fit in 120k context window. 2. Copy **all** locked dimensions from analysis into the plan's first section — no summarizing away Part D micro-locks. 3. For brownfield: read `<<OUTPUTS_DIR>>/analysis/repo_summary.md` and `<<SRC_DIR>>/`; phases must **extend** existing code, not rebuild from scratch. 4. Self-check before finishing: every feature in the spec has at least one phase; no phase exceeds the hard limits (2–3 tasks, 8–10 files). Inspect `<<OUTPUTS_DIR>>/` for context (`<<OUTPUTS_DIR>>/analysis/specification_index.md`, `<<OUTPUTS_DIR>>/analysis/specification_completeness.md`, etc.). ## Project Knowledge Base (if available) - Check `.claude/agents/` for specialized agent definitions with project-specific guidance - Check `<<OUTPUTS_DIR>>/` for project context (CONTEXT.md, ARCHITECTURE.md, CODEMAP.md) - Follow any relevant guidelines and conventions found in these files - CLAUDE.md at project root contains project-level instructions (auto-loaded by SDK) Note: full Knowledge Base initialization happens later on the backend, inside the generation phase — you don't need it to plan. Your task is to create a detailed implementation plan that breaks the work into phases. Each phase should be: - Self-contained (can run independently) - Testable (has associated unit tests) - Committable (produces meaningful commits) - Focused on a logical unit of work ## Workflow ### 1. Read Specifications - Read all files in `<<SPEC_DIR>>/` — for non-text formats (PDF, DOCX, PPTX, XLSX, CSV), use the `read_document` MCP tool instead of the IDE's built-in file reader. For images, use the IDE's built-in reader. - Review `<<OUTPUTS_DIR>>/analysis/specification_index.md` if it exists - If brownfield: read `<<OUTPUTS_DIR>>/analysis/repo_summary.md` and scan `<<SRC_DIR>>/` for modules to preserve, extend, or refactor - **CRITICAL**: Read `<<OUTPUTS_DIR>>/analysis/specification_completeness.md` and extract ALL LOCKED DIMENSIONS from Parts A-E - **Read Part F (Integration & Deployment Readiness)** to determine if the plan should include deployment and e2e testing phases - Understand the full scope of the project ### 2. Create Implementation Plan - Write the plan to **EXACTLY** `<<OUTPUTS_DIR>>/planning/IMPLEMENTATION_PLAN.md`. The backend contract validator expects this exact filename — any other name (e.g. `plan.md`, `implementation.md`) will cause `run_generation` to be rejected with `PLAN_MISSING`. - If the file would exceed ~300 lines, write it in parts and merge with `cat`. **MANDATORY FIRST SECTION: "Architectural Decisions - Locked Values"** ```markdown ## Architectural Decisions - Locked Values These values are LOCKED from <<OUTPUTS_DIR>>/analysis/specification_completeness.md and MUST NOT be changed by any phase agent. **AGGRESSIVE ENFORCEMENT**: Any deviation from these locks is a CRITICAL error. ### Part A: Universal Dimensions (ALL MANDATORY) | Dimension | Locked Value | Implementation Approach | |-----------|--------------|------------------------| | A1. Data Persistence | [copy from spec_completeness] | [how we implement it] | | A2. Infrastructure | [copy from spec_completeness] | [how we implement it] | | A3. Scale Target | [copy from spec_completeness] | [how we implement it] | | A4. Technology Stack | [copy from spec_completeness] | [how we implement it] | | A5. Quality & Testing | [copy from spec_completeness] | [how we implement it] | | A6. Scope Boundaries | [copy from spec_completeness] | [how we implement it] | ### Part B: Technology-Specific Dimensions (if applicable) [Copy all locked B1-B5 dimensions that apply to this project] ### Part C: Project-Specific Dimensions (discovered) [Copy all discovered and locked dimensions from spec_completeness] ### Part D: Micro-Level Consistency Locks (AGGRESSIVE ENFORCEMENT) | Convention | Locked Value | Examples | |------------|--------------|----------| | D1. File naming | [e.g., kebab-case] | user-service.ts, api-routes.ts | | D1. Directory naming | [e.g., plural] | components/, services/, utils/ | | D1. Function naming | [e.g., verb-first camelCase] | getUser(), createOrder() | | D1. Variable naming | [e.g., camelCase] | userName, orderItems | | D2. Async style | [e.g., async/await] | Always use async/await, never .then() | | D2. Error handling | [e.g., throw exceptions] | throw new AppError(), not return null | | D2. Import style | [e.g., named imports] | import { X } from 'y', not import X | | D3. Source location | [e.g., src/] | All source code under src/ | | D3. Test location | [e.g., adjacent] | user.ts → user.test.ts | | D4. Commit granularity | [e.g., atomic] | Target 40-50 commits | | D4. Commit format | [e.g., conventional] | feat(auth): add login endpoint | ### Part E: Feature Completeness Checklist [List all features with their required sub-tasks] ``` ### Part F: Integration Environment — Locked Values (Only if `<<OUTPUTS_DIR>>/analysis/specification_completeness.md` Part F says INTEGRATION_TESTS_READY) Copy all integration details from Part F's locked values table into `<<OUTPUTS_DIR>>/planning/IMPLEMENTATION_PLAN.md` so phase agents can reference them when writing deployment artifacts. **DO NOT add deploy/e2e phases to `<<OUTPUTS_DIR>>/planning/IMPLEMENTATION_PLAN.md`.** Application phases may include writing deployment artifacts as code (Dockerfile, k8s manifests, GitHub Actions workflow files, e2e test suite) but must NOT execute live deployments. **ADDITIONALLY write EXACTLY `<<OUTPUTS_DIR>>/planning/e2e-test-plan.md`** as a markdown file using the same phase conventions as `IMPLEMENTATION_PLAN.md`. The backend contract validator expects this exact filename — if Part F is `INTEGRATION_TESTS_READY` and this file is missing, `run_generation` will be rejected with `E2E_PLAN_MISSING`. This file drives the separate deploy → test → fix loop that runs after all application code is generated. Phases cover: - Phase 1: Initial deployment and smoke test — deploy to target env, verify health check passes - Phase 2–N: Run full e2e suite, fix failures — one round of test-and-fix per phase, up to max_rounds from Part F (default: 3) Planning guidance for INTEGRATION_TESTS_READY: - Deployment artifacts (Dockerfile, k8s, CI/CD) are first-class code in the application phases - No live deployments or external service calls during application codegen phases - The `e2e-test-plan.md` phases use the same phase agent template — write them like code phases - Agents trigger deploys via `gh workflow run` and read results via `gh run view` - If spec uses Helm: include a phase for Helm chart generation (Chart.yaml, values.yaml, templates/) - If spec uses ESO: include SecretStore + ExternalSecret manifests in the infrastructure phase - Include namespace bootstrap in deploy workflow: namespace creation, KSA, Workload Identity binding, secret sync - Include teardown workflow generation as part of the infrastructure/CI-CD phase - Warn about compile-time env vars: NEXT_PUBLIC_*, VITE_*, REACT_APP_* must be Docker build args ### CRITICAL: PHASE SIZING — SMALL, FOCUSED PHASES - **Prefer more phases over bigger phases.** Typical projects need 10-20+ phases. - Each phase MUST focus on a **single component and a single concern** (e.g., "Backend: auth endpoints" not "Backend + Frontend auth"). - **Hard limits per phase:** - Maximum 2-3 tasks per phase - Maximum 3-5 commits expected per phase - Maximum 8-10 files created or modified per phase - If a phase would touch both backend AND frontend, split it into separate phases - If a phase has more than 3 tasks, split it - **Component-specific splitting guidance:** - **Backend**: Split by architectural layer or domain area. 4-6 phases is typical: - data models/schema, core services, API endpoints, auth/middleware, tests - **Frontend**: Split by **user-facing feature**, not by layer. Each distinct feature or screen should be its own phase. If the spec lists 5 features, the frontend needs at least 5 phases: - ❌ BAD: "Frontend: implement all pages and state management" (one giant phase) - ❌ BAD: "Frontend: components" then "Frontend: pages" (split by layer, still too broad) - ✅ GOOD: "Frontend: dashboard page", "Frontend: user profile page", "Frontend: search feature", "Frontend: settings page", "Frontend: file upload feature" (one phase per feature) - Each frontend feature phase includes its components, state, API integration, and styling together - **Infrastructure/DevOps**: 1-2 phases typically sufficient - **Testing**: Dedicated test phases for integration/E2E tests that span components - Each phase must be completable in a **single focused session** — the implementing agent should not need to juggle more than one area of the codebase at a time. - Each phase should have: - A clear name and description - List of tasks to be completed (2-3 max) - Dependencies on previous phases (if any) - **ENFORCEMENT CHECKPOINT**: List which Part D conventions apply to this phase - Phases should follow a logical progression: - Phase 1: Project setup, dependencies, basic structure (following Part A and Part D conventions) - Phase 2-N: Core functionality implementation (following Parts B, C, D conventions) - Final Phase: Testing, documentation, deployment configuration (following Part A and Part E) ### Per-phase optional agent MCPs (markdown annotation) The harness attaches **Playwright MCP** and **Figma MCP** to Claude Code only when needed. **These are not** the Playwright npm package used inside the repo for E2E tests — they are separate agent tools. For each phase heading in the markdown, add an `**Agent MCPs**:` line to control which MCPs load for that phase: - **Omit the line**: use the full set of MCPs the generation already has enabled (default; backward compatible). - **`**Agent MCPs**: none`**: no optional Playwright/Figma MCPs — use for pure backend, data/schema, batch/ETL, or internal APIs with no UI or Figma handoff. - **`**Agent MCPs**: playwright`**: phases that implement or manually verify a **browser UI** (when user enabled playwright). - **`**Agent MCPs**: figma`** or **`**Agent MCPs**: figma, playwright`**: phases that consume **Figma** and/or UI work (when enabled). Split backend and frontend into separate phases so backend phases use `none` while UI phases list `playwright`. Example phase heading: ```markdown ## Phase 3: Frontend Dashboard Feature **Agent MCPs**: playwright ``` ### Example Phase Breakdown for a task management app with 4 features (dashboard, projects, tasks, settings): - Phase 1: Project Setup - Initialize both backend and frontend projects, dependencies, config - Phase 2: Backend Data Models & Schema - Database schema, ORM models, migrations - Phase 3: Backend API & Services - Endpoints, business logic, auth middleware - Phase 4: Backend Error Handling & Tests - Error handling, validation, unit tests - Phase 5: Frontend Shell & Shared Components - Layout, routing, design system, API client - Phase 6: Frontend: Dashboard Feature - Dashboard page, widgets, data visualization - Phase 7: Frontend: Projects Feature - Project list, create/edit, project detail page - Phase 8: Frontend: Tasks Feature - Task board, task CRUD, drag-and-drop, filters - Phase 9: Frontend: Settings Feature - User settings, preferences, profile management - Phase 10: Frontend: Auth Flow & Error Handling - Login/signup pages, protected routes, error boundaries - Phase 11: Frontend Tests - Component and integration tests across features - Phase 12: Infrastructure & Deployment - Docker, docker-compose, environment config - Phase 13: Integration Testing & Polish - E2E tests, final verification, documentation Notice: backend is 3 phases (layer-split), frontend is 7 phases (feature-split). This is intentional — frontend features are heavier and each one involves components, state, styling, and API integration. ### Important - Do NOT start implementation — only create the plan - Ensure phases are balanced (not one huge phase and many tiny ones) - Each phase should represent 1-3 days of focused work - Create ONLY markdown files (`IMPLEMENTATION_PLAN.md` and optionally `e2e-test-plan.md`) When done, state: - Path of plan file(s) written - Phase count - Next step: run `run_generation` to start parallel codegen agents (2–8 hours).
