Frontend Reconnaissance

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

Steps

Step 0: Detect Environment

Scan the project to identify the complete frontend stack:

• Check for framework: next.config.*, nuxt.config.*, svelte.config.*, astro.config.*, vite.config.*, remix.config.*
• Check package.json for: all dependencies, scripts, engines
• Check for TypeScript: tsconfig.json — note strictness level
• Check for monorepo: pnpm-workspace.yaml, turbo.json, nx.json, lerna.json
• Check deployment: vercel.json, netlify.toml, fly.toml, Dockerfile, CI/CD configs

This is a read-only reconnaissance — do not modify anything.

Step 1: Map Component Tree

Understand how the UI is organized:

• Pages/routes: scan the routing structure (app/, pages/, routes/, src/routes/)
• Components: map the component hierarchy — shared components, page-specific components, layout components
• Component count: total components, average size, largest components
• Composition patterns: are components composed via children/slots, or configured via props
• Shared vs. page-specific: ratio of reusable to one-off components

Step 2: Map Architecture

Understand the technical architecture:

• Routing: file-based, config-based, or library-based — nested routes, dynamic routes, catch-all routes
• State management: what library (Zustand, Redux, Pinia, Svelte stores, React Context), how is state organized, is there a clear pattern
• Data fetching: server components, loaders, API routes, client-side fetching, tRPC, GraphQL — what patterns are used
• API integration: how does the frontend talk to the backend — REST, GraphQL, tRPC, direct DB access
• Styling: Tailwind, CSS Modules, styled-components, vanilla CSS — is there a design system or token system
• Build config: Vite, webpack, Turbopack — any custom plugins, aliases, or unusual configuration

Step 3: Assess Quality Metrics

Measure the current state:

• Bundle size: check build output if available, or estimate from dependencies
• Dependency count: total deps, heavy deps, potentially unused deps
• Dependency freshness: how many major versions behind on key dependencies (framework, React, etc.)
• Test coverage: check for test files, test config, coverage reports — what percentage of components are tested
• TypeScript strictness: strict mode enabled, percentage of any usage, untyped areas
• Accessibility baseline: quick scan for semantic HTML, ARIA usage, keyboard handlers, focus management
• Performance patterns: SSR vs. CSR split, code splitting usage, image optimization

Step 4: Present Assessment

## Frontend Reconnaissance

### Stack
- **Framework:** [name + version]
- **Language:** [TypeScript/JavaScript — strictness level]
- **Styling:** [approach]
- **State management:** [library/pattern]
- **Build tool:** [name + config notes]
- **Hosting:** [platform]
- **Testing:** [framework — coverage level]

### Architecture
- **Pages:** [count] routes — [routing pattern]
- **Components:** [count] total — [count] shared, [count] page-specific
- **Data fetching:** [pattern] — [server/client split]
- **API integration:** [approach]

### Health Indicators
| Metric | Status | Notes |
|--------|--------|-------|
| Bundle size | [size or unknown] | [assessment] |
| Dependencies | [count] | [freshness, issues] |
| Test coverage | [percentage or unknown] | [what's tested] |
| TypeScript | [strict/loose/none] | [any usage level] |
| Accessibility | [baseline assessment] | [key gaps] |
| Performance | [assessment] | [SSR/CSR, code splitting] |

### Strengths
- [what's well done]

### Risks
- [what could cause problems]

### Modernization Recommendations
1. [highest value improvement] — [effort] — [impact]
2. [next improvement] — [effort] — [impact]
3. [next improvement] — [effort] — [impact]

Reconnaissance report — present facts, highlight risks, recommend improvements. Do not make changes.

Delivery

If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
