Strengths

@eko/* package scope consistently applied across all workspaces
Clear separation: apps deploy, packages share
New .claude/agents/ provides autonomous workflow definitions
packages/ui/ consolidates shared components (previously scattered)
Agent routing validation in CI (agents-routing-check.ts)

Weaknesses

2. Build System & Tooling

Score: 93 (A) (+1 from v1)

Turbo Configuration

{
  "tasks": {
    "build": { "dependsOn": ["^build"], "outputs": [".next/**", "dist/**", "storybook-static/**"] },
    "dev": { "cache": false, "persistent": true },
    "lint": { "dependsOn": ["^build"] },
    "typecheck": { "dependsOn": ["^build"] },
    "test": { "dependsOn": ["^build"] }
  }
}

Metrics

Metric	Value
Local Turbo cache	13 MB (408 artifacts)
Web app .next build	37 MB
Storybook static	7.4 MB
node_modules	649 MB
bun.lock lines	1,278

Strengths

Turbo task graph correctly models dependencies with ^build
Bun provides fast install and execution (1.1.0)
Local caching working effectively (13 MB / 408 artifacts)
TypeScript incremental builds enabled
All dependencies locked to specific versions

Weaknesses

No remote caching configured (Vercel Remote Cache or custom)
Each CI job re-installs dependencies from scratch

3. Code Quality & Standards

Score: 90 (A-) (unchanged)

Biome Configuration (v2.3.9)

{
  "linter": {
    "rules": {
      "noUnusedImports": "error",
      "noUnusedVariables": "error",
      "noExplicitAny": "warn",
      "noNonNullAssertion": "off"
    }
  },
  "formatter": {
    "indentStyle": "space",
    "indentWidth": 2,
    "lineWidth": 100,
    "quoteStyle": "single"
  }
}

Strengths

Single tool (Biome) eliminates config drift between lint/format
Strict on unused code (errors, not warnings)
CSS modules and Tailwind directives supported
Import organization automated
.editorconfig present for cross-editor consistency

Weaknesses

No pre-commit hooks (husky/lefthook not configured)
noExplicitAny is "warn" not "error"
noNonNullAssertion disabled
Quality enforcement relies entirely on CI

4. Type System Configuration

Score: 94 (A) (unchanged)

Base Config (tsconfig.base.json)

{
  "compilerOptions": {
    "target": "ES2022",

9. CI/CD & DevOps

Score: 88 (B+) (unchanged)

GitHub Actions Pipeline

Triggers: push/PR to main/dev

Jobs (Parallel):
1. docs-lint      - Validates markdown front-matter
2. agents-routing - Validates agent ownership [NEW]
3. lint           - Biome check
4. typecheck      - tsc
5. test           - Vitest

Job (Sequential):
6. build          - Depends on all above

Strengths

Full quality gate (docs, agents, lint, types, tests, build)
Parallel execution for independent jobs
Build blocked until all checks pass
--frozen-lockfile ensures determinism

No deployment automation
No GitHub Actions dependency caching

10. Security

Score: 85 (B) (-2 from v1)

Strengths

Area	Status

Secret Scanning	Missing (no GitHub scanning)	P1
SSRF Prevention	Missing (no private IP blocking)	P2
Rate Limiting	Missing (no per-user limits)	P2
Admin Authorization	Incomplete (run_now disabled)	P2

Recommendations

Add .github/dependabot.yml for npm vulnerability scanning
Enable GitHub secret scanning in repository settings

UI consistency	Low	-1	Storybook + shared components now unified

Recommended Next Steps

P0 - Critical

Add Dependabot for dependency vulnerability scanning
Enable GitHub secret scanning
Add pre-commit hooks (husky + lint-staged)
Configure coverage reporting and set minimum thresholds

P2 - Medium Priority
