# Implementation Readiness Assessment Report

**Date:** 2026-07-07
**Project:** Wordle Clone

## PRD Analysis

### Functional Requirements

19 FRs extracted from `prds/prd-wordle-2026-07-07/prd.md`:

FR-1: First-visit detection — detect prior visits and show/skip rules screen
FR-2: Rules display — show game rules with Play button
FR-3: Grid rendering — 5×6 grid with per-cell color feedback
FR-4: Keyboard rendering — QWERTY with per-key best-feedback highlighting
FR-5: Guess submission — type 5 letters via physical or on-screen keyboard
FR-6: Invalid word rejection — "Unknown word" message, retry without burning attempt
FR-7: Feedback scoring — greens first, yellows to remaining count, excess gray
FR-8: Win detection — all-green row → Screen 3 congratulations
FR-9: Loss detection — 6th wrong guess → Screen 3 with word revealed
FR-10: Daily word selection — same word all players, midnight EST/EDT
FR-11: Play Again word selection — weighted random by skill
FR-12: Player skill tracking — compute and persist skill metric
FR-13: Results display — outcome + attempt count or correct word
FR-14: Statistics display — games played, win rate, histogram, streaks
FR-15: Play Again button — triggers new game from Screen 3
FR-16: Multi-algorithm solver — ≥2 algorithms, pre-compute attempt counts
FR-17: Word ranking output — difficulty score per word from solver data
FR-18: Word bank curation — 5-letter words, recent usage frequency
FR-19: Browser persistence — localStorage for stats, cookie, skill metric

### Non-Functional Requirements

NFR-1: Responsive design — 375px phone through desktop
NFR-2: Feedback latency — acceptable round-trip, no optimistic UI for v1
NFR-3: Persistence — stats, cookie, skill metric survive browser close
NFR-4: Stateless server — no session state, context in request
NFR-5: Wire format — colors as 'g', 'y', 'x'
NFR-6: TypeScript everywhere — client, server, solver, shared types
NFR-7: Word bank confidentiality — guessable list never sent to client

### PRD Completeness Assessment

**Verdict: Complete.** The PRD defines 19 testable FRs with consequences. 5 user journeys cover the full experience. Success metrics are appropriate for a learning project. 4 open questions are non-blocking implementation details. The document is well-structured and ready for implementation.

### Additional Requirements from Architecture

- Monorepo: client/ (React+Vite), server/ (Express), solver/, shared/, data/
- Stack: TypeScript 6.x, Node 24 LTS, React 19.x, Vite 8.x, Express 5.x
- API: 3 REST endpoints with typed contracts in shared/src/api.ts
- No database — word bank is static JSON
- Deterministic daily word (date → ID)
- Weighted random Play Again selection
- Single localStorage key with typed PersistedState
- Deployment: home Linux server, Express serves API + static SPA
- Wire format: 'g'/'y'/'x' for feedback colors

### Coverage Statistics

- **Total PRD FRs:** 19
- **FRs covered in epics:** 19
- **Coverage:** 100%
- **Missing FRs:** 0

## UX Alignment Assessment

### UX Document Status

**Not found.** No dedicated UX design document exists.

### Assessment

UX is implied — the PRD defines 3 screens (Rules, Game, Results), user journeys with named behaviors, color feedback requirements, and responsive design. For a solo learning project, this level of UX detail in the PRD is sufficient. Key UX concerns are addressed:

- Screen flow: PRD UJ-1 through UJ-5 cover the complete experience
- Visual design: green/yellow/gray colors, keyboard highlighting, grid layout
- Responsive: Architecture mandates CSS media queries, 375px through desktop
- Error states: "Unknown word" message, loss reveal, network error message
- Persistence: resume mid-game after browser close

### Warnings

None. The PRD journey-led approach provides adequate UX guidance for implementation. A dedicated UX design would add value for a public launch but is not required for v1.

## Epic Quality Review

### Epic Structure Validation

| Check | Epic 1: Play the Game | Epic 2: Solver Engine |
|---|---|---|
| User-centric title | ✅ "Play the Game" | ✅ (developer tool, acceptable for scope) |
| Delivers standalone value | ✅ Complete playable game | ✅ Works independently on word bank data |
| No forward dependencies | ✅ Epic 2 not required for Epic 1 | ✅ Standalone offline script |
| FR coverage | ✅ 17 of 19 FRs | ✅ 2 of 19 FRs |

### Story Quality Assessment

| Story | Sizing | Forward Deps | AC Format | AC Testable |
|---|---|---|---|---|
| 1.1 Foundation | ✅ Single agent | ✅ None | ✅ Given/When/Then | ✅ |
| 1.2 Feedback | ✅ Single agent | ✅ Only 1.1 | ✅ Given/When/Then | ✅ |
| 1.3 Play Again | ✅ Single agent | ✅ Only 1.1, 1.2 | ✅ Given/When/Then | ✅ |
| 2.1 Solver | ✅ Single agent | ✅ None | ✅ Given/When/Then | ✅ |

### Dependency Analysis

- **Within Epic 1:** Strictly sequential — 1.1 → 1.2 → 1.3. No forward references. ✅
- **Epic-to-Epic:** Epic 2 is independent of Epic 1. ✅
- **Database/Entity:** No database. Word bank is static JSON. ✅

### Best Practices Compliance

- [x] Epics deliver user value
- [x] Each epic functions independently
- [x] Stories appropriately sized for single dev agent
- [x] No forward dependencies
- [x] No database tables created upfront
- [x] Clear acceptance criteria in Given/When/Then format
- [x] FR traceability maintained (coverage map)

### Findings

| Severity | Finding |
|---|---|
| 🟡 Minor | Epic 2 title "Solver Engine & Word Ranking" is developer-facing. Could reframe as "Data-Driven Difficulty" to emphasize user impact, but acceptable for a learning project where the solver is genuinely a self-contained offline tool. |

**Verdict: PASS.** No critical or major violations. Epics and stories are well-structured and ready for implementation.

## Summary and Recommendations

### Overall Readiness Status

**READY** ✅

All planning artifacts are complete, aligned, and traceable. The project can proceed to implementation.

### Assessment Summary

| Dimension | Status | Notes |
|---|---|---|
| PRD completeness | ✅ | 19 FRs, 5 UJs, 5 SMs, testable consequences |
| Architecture alignment | ✅ | 12 ADs cover all PRD concerns, versions verified current |
| FR coverage in epics | ✅ | 19/19 FRs (100%) mapped to stories |
| Epic quality | ✅ | User-value focused, no forward deps |
| Story quality | ✅ | Given/When/Then ACs, single-agent sized |
| UX coverage | ✅ | Journey-led PRD sufficient for v1 |
| Architecture-epic alignment | ✅ | Starter template, monorepo, API contracts covered |

### Findings

- **🟡 Minor (1):** Epic 2 title is developer-facing. Acceptable — the solver is a self-contained offline tool.

### Recommended Next Steps

1. **Sprint Planning** — `bmad-sprint-planning` to sequence stories for implementation
2. **Story Creation** — `bmad-create-story` to prepare the first story with full dev context
3. **Dev Story** — `bmad-dev-story` to implement

### Final Note

This assessment found 1 minor finding across 6 validation dimensions. No blockers. The project is ready for Phase 4 — Implementation.
