## Real-World Testing (T3 Stack Production Codebase)
|
||||
|
||||
**Test Environment**:
|
||||
- **Project**: Méthode Aristote (Next.js + tRPC + Prisma + pnpm)
|
||||
- **Date**: 2026-01-28
|
||||
- **Commands tested**: 12 (git, pnpm, Vitest, TypeScript, Prisma)
|
||||
- **Full report**: `claudedocs/rtk-test-results-aristote.md`
|
||||
|
||||
### Validated Results
|
||||
|
||||
| Command | Baseline | RTK | Reduction | Verdict |
|
||||
|---------|----------|-----|-----------|---------|
|
||||
| `git log -20` | 9.3K | 1.1K | **88.6%** | ✅ Excellent |
|
||||
| `git diff HEAD~1` | 28.4K | 1.8K | **93.5%** | ✅ Excellent |
|
||||
| `git status` | 260 | 87 | **66.5%** | ✅ Good |
|
||||
| `find src/ -name "*.tsx"` | 38.5K | 2.4K | **93.9%** | ✅ Excellent |
|
||||
|
||||
**Average (working): 85.6%** (higher than initial 72.6% due to larger project scale)
|
||||
|
||||
### Critical Bug Discovered
|
||||
|
||||
**Issue**: `rtk git log --oneline` fails with argument parsing error
|
||||
|
||||
```bash
|
||||
$ rtk git log --oneline -20
|
||||
error: unexpected argument '--oneline' found
|
||||
```
|
||||
|
||||
**Workaround**: Use `rtk git log -- -20` (works, 88.6% reduction)
|
||||
|
||||
**Impact**: CRITICAL - Blocks common git flags (`--oneline`, `--graph`, `--stat`, etc.)
|
||||
|
||||
**Root Cause**: RTK argument parser doesn't transparently pass flags to git
|
||||
|
||||
**Upstream PR needed**: Fix clap parser to treat everything after `git` as passthrough
|
||||
|
||||
### Modern Stack Gaps (pnpm + Vitest)
|
||||
|
||||
**1. pnpm Support (MISSING - CRITICAL)**
|
||||
|
||||
| Command | Chars | Reduction Possible |
|
||||
|---------|-------|-------------------|
|
||||
| `pnpm list --depth=0` | 3,900 | ~80% (→ 700) |
|
||||
| `pnpm outdated` | 18,600 | ~90% (→ 1,800) |
|
||||
|
||||
**Superfluous content**: Box-drawing chars (┌─┐), "Legend:" headers, full paths
|
||||
|
||||
**Value**: pnpm is #2 package manager, used by T3 Stack, Turborepo, Nx (millions of devs)
|
||||
|
||||
**2. Vitest Support (MISSING - HIGH)**
|
||||
|
||||
| Command | Chars | Reduction Possible |
|
||||
|---------|-------|-------------------|
|
||||
| `pnpm test` (43 passing) | 10,500 | ~90% (→ 1,000) |
|
||||
|
||||
**Superfluous content** (85%):
|
||||
- ANSI color codes: `[1m[46m [32m`
|
||||
- Checkmarks: `✓` (replace with "PASS")
|
||||
- Test hierarchy: `[2m > [22m` (flatten)
|
||||
|
||||
**Optimal output**: `PASS (43)\nFAIL (0)\nTime: 450ms` (50 chars vs 10.5K)
|
||||
|
||||
**3. TypeScript Support (MISSING - MEDIUM)**
|
||||
|
||||
| Command | Chars | Reduction Possible |
|
||||
|---------|-------|-------------------|
|
||||
| `tsc --noEmit` (errors only) | ~5,000 | ~70% (→ 1,500) |
|
||||
|
||||
**Superfluous content**: Code snippets, underlines, full stack traces
|
||||
|
||||
**Optimal output**: `file.ts:45:12 - error TS2322: Type 'string' not assignable` (one-line per error)
|
||||
|
||||
### ROI Analysis (T3 Stack Adoption)
|
||||
|
||||
**Current RTK v0.2.0 (git only)**:
|
||||
- Commands covered: ~40% of dev session
|
||||
- Typical session: 11K tokens → 5K tokens (~55% reduction)
|
||||
|
||||
**With pnpm + Vitest + TypeScript support (proposed v0.3.0)**:
|
||||
- Commands covered: ~85% of dev session
|
||||
- Typical session: 11K tokens → 2.2K tokens (~80% reduction)
|
||||
|
||||
**Dev effort estimate**: 1 week (7 days)
|
||||
- pnpm: 2 days
|
||||
- Vitest: 3 days
|
||||
- TypeScript: 1 day
|
||||
- Bug fix (git args): 1 day
|
||||
|
||||
**User value**: **From niche tool → essential LLM dev tooling** for modern JS stacks
|
||||
|
||||
### Pattern Analysis (Cross-Tool)
|
||||
|
||||
**Superfluous patterns** repeated across modern dev tools:
|
||||
|
||||
| Pattern | % of Output | Tools | Fix |
|
||||
|---------|-------------|-------|-----|
|
||||
| Box-drawing (`┌─┐`) | 60-70% | pnpm, tables | Strip |
|
||||
| ANSI codes (`[32m`) | 20-30% | Vitest, colored | Strip |
|
||||
| Marketing tips | 5-15% | Prisma, pnpm | Remove |
|
||||
| Verbose paths | 10-20% | All | Abbreviate |
|
||||
| Progress bars | 5-10% | All | Remove |
|
||||
|
||||
**Insight**: Modern CLI tools optimize for **human readability** (colors, boxes, progress bars) but **waste tokens** for LLMs. Average reduction potential: **84%** across all unsupported tools.
|
||||
|
||||
### Updated Recommendation Post-Testing
|
||||
|
||||
**Score**: Still **4/5 (GOOD)** but with clearer roadmap
|
||||
|
||||
**Current strengths**:
|
||||
- ✅ Git workflows: 85.6% avg reduction (validated on production codebase)
|
||||
- ✅ File operations: 93.9% reduction (find)
|
||||
- ✅ Fast, zero-config, drop-in wrapper
|
||||
|
||||
**Blockers for 5/5 (CRITICAL) rating**:
|
||||
1. ❌ Git argument parsing bug (blocks `--oneline`, `--graph`, etc.)
|
||||
2. ❌ Missing pnpm support (critical for T3 Stack, 40% of npm downloads)
|
||||
3. ❌ Missing test framework support (Vitest/Jest = 20-30% of dev sessions)
|
||||
|
||||
**Path to 5/5**:
|
||||
- Fix git arg parsing → **1 day dev**
|
||||
- Add pnpm support → **2 days dev**
|
||||
- Add Vitest support → **3 days dev**
|
||||
- **Total: 1 week investment** → RTK becomes essential for modern stacks
|
||||
|
||||
**Upstream contribution value**: Real-world T3 Stack testing provides:
|
||||
- Quantitative evidence (12 commands, 53KB benchmarks)
|
||||
- Implementation guide (Rust pseudocode ready)
|
||||
- Clear ROI (80% reduction, 85% command coverage)
|
||||

|

|
||||
## Final Recommendation
|
||||
|
||||
**Score: 4/5 (GOOD)**
