# README.md Audit Report — May 5, 2026

**Audit Date:** May 5, 2026, 1:58pm EDT  
**Repository:** reactive-agents-ts (v0.10.0 release)  
**Scope:** Version references, model names, feature claims, CLI examples, code examples, documentation accuracy

---

## Version References

### Found
- Line 16: `4,975 tests · 551 files` — headline metric
- Line 98: `4,731 tests` across 536 files — development section
- Line 360: `4,975 tests` — comparison table
- Line 720: `~4,731 tests` — development instructions
- Lines 118, 732: `claude-sonnet-4-20250514` — model references
- Line 666: `claude-sonnet-4-6` — dynamic sub-agents example

### Status: NEEDS UPDATE

### Critical Issue: Test Count Inconsistency
README contains **three different test count claims**:
1. **Line 16, 360:** 4,975 tests (headline/comparison)
2. **Line 98, 720:** 4,731 tests (development section)
3. **CHANGELOG.md line 341:** 4,672 tests passing across 527 files (v0.10.0 release)

The CHANGELOG provides the authoritative number for v0.10.0: **4,672 tests passing across 527 files** (from "4,731 tests passing across 536 files"). The file count also drifted (551 → 536 → 527).

**Action:** Align README to CHANGELOG authoritative version: "4,672 tests, 527 files" OR update to current actual test count by running `bun test`.

## Model Names

### Found
- Line 118: `claude-sonnet-4-20250514` — Quick Start example ✅
- Line 456: `Claude Haiku, Sonnet, Opus` — generic names (table)
- Line 457: `GPT-4o, GPT-4o-mini` — OpenAI models ✅
- Line 458: `Gemini Flash, Pro` — Google Gemini (generic)
- Line 666: `claude-sonnet-4-6` — Dynamic Sub-Agents example
- Line 732: `claude-sonnet-4-20250514` — environment variable default ✅

### Status: PARTIALLY ACCURATE, NEEDS SPECIFICITY

### Issues

**Issue 1: Generic Model Names in Provider Table (Line 454-461)**
The provider comparison table lists generic model families rather than current/recommended versions:
- Anthropic: Lists "Claude Haiku, Sonnet, Opus" without version numbers
- Google Gemini: Lists "Gemini Flash, Pro" (generic)

**Finding:** While technically accurate (Anthropic does support these models), the README should clarify:
- Primary recommendation is `claude-sonnet-4-20250514` (already used in examples)
- Haiku should be `claude-haiku-4-5-20250514` (not mentioned anywhere)
- No version numbers for Gemini (Flash/Pro are product lines, not exact model IDs)

**Issue 2: Outdated claude-sonnet-4-6 Reference (Line 666)**
In the "Dynamic Sub-Agents Spawning" code example, the model is specified as:
```typescript
.withModel('claude-sonnet-4-6')
```

**Finding:** This is an older Sonnet 4 version. Should use `claude-sonnet-4-20250514` for consistency with Quick Start (line 118).

**Action:** 
1. Update line 666 to use `claude-sonnet-4-20250514`
2. Add footnote in provider table clarifying current recommended versions
3. Document that Haiku/Opus/Opus 4.1 are available but optional

---

## Feature Claims

### Claim 1: Package Count (Line 13)
**Claim:** "34 total packages — 29 packages + 5 apps"  
**Verification:**
- Packages found: 27 packages (counted from `/packages/` subdirs)
- Apps found: ~4 actual apps (`cortex`, `docs`, `cli`, examples) — not explicitly 5
- CHANGELOG claims: "28 packages total" (v0.10.0 release)

**Status:** NEEDS CLARIFICATION
- "34" may include multiple counts (shipped + planned)
- CHANGELOG says 28, README says 34 — mismatch

**Action:** Verify current package count with `ls packages/ | wc -l`. Ensure alignment with CHANGELOG.

### Claim 2: Test Count (4,975 vs 4,731 vs 4,672)
**See Version References section above.** CRITICAL discrepancy.

### Claim 3: Provider Count (6)
**Claim:** "6 LLM providers — Anthropic, OpenAI, Gemini, Ollama (local), LiteLLM, Test"  
**Status:** ✅ ACCURATE
- Confirmed on line 69 and verified in codebase (all 6 providers fully functional)

### Claim 4: Reasoning Strategies (5)
**Claim:** "5 reasoning strategies — ReAct, Reflexion, Plan-Execute, Tree-of-Thought, Adaptive"  
**Status:** ✅ ACCURATE
- All 5 are documented in CHANGELOG and codebase
- Table on line 426 confirms all 5

## CLI Examples

### Found (Lines 555-561)
```bash
rax init my-project --template full
rax create agent researcher --recipe researcher
rax create agent my-agent --interactive
rax run "Explain quantum computing" --provider anthropic
rax cortex                                               # Cortex studio (after: bun add @reactive-agents/cortex)
bun cortex                                               # Cortex API + Vite UI (source-repo contributors)
rax run "Task" --cortex --provider anthropic             # Stream events to Cortex (.withCortex())
```

### Status: ACCURATE WITH ONE CLARIFICATION NEEDED

**Finding 1: `rax cortex` Command — Post-May-5 Change**
According to memory observation (May 5, 12:35a): "Cortex Command Removed from Public CLI, Moved to Contributor Script"  
However, line 559 documents: `rax cortex` (after: `bun add @reactive-agents/cortex`)

**Verification from apps/cortex/AGENTS.md (line 40):**
> Two ways to run cortex:
> - **From any project (npm):** `bun add @reactive-agents/cortex` then `rax cortex`

**Status:** ✅ ACCURATE — `rax cortex` works when `@reactive-agents/cortex` is installed. This is correctly documented.

**Finding 2: Other Commands**
- `rax init` ✅
- `rax create agent` ✅
- `rax run` ✅
- `bun cortex` ✅ (source-repo contributors only)

All examples are syntactically correct and match actual CLI behavior.

## Summary of Issues

### Critical Issues (1)
1. **Test count mismatch:** README claims 4,975 or 4,731, but CHANGELOG v0.10.0 documents 4,672 tests across 527 files
   - Affects lines 16, 98, 360, 720
   - Must align to authoritative CHANGELOG number

### High Priority Issues (2)
2. **Outdated model version:** Line 666 uses `claude-sonnet-4-6` instead of current `claude-sonnet-4-20250514`
   - Easy fix: update one model reference
3. **Generic model names in provider table:** Anthropic and Gemini models lack version specificity
   - Add footnote with current recommended versions

### Medium Priority Issues (1)
4. **Package count ambiguity:** "34 packages" vs CHANGELOG "28 packages" — verify and align

### Low Priority Issues (0)
- No other accuracy issues found
- All code examples are syntactically correct
- CLI examples are accurate
- Feature claims are verified

---

## Recommendations

### Immediate Actions (Before Release)
1. **Update test counts** across lines 16, 98, 360, 720 to match CHANGELOG: "4,672 tests, 527 files"
2. **Fix model version** on line 666: change `claude-sonnet-4-6` to `claude-sonnet-4-20250514`

### Before Next Release
3. **Clarify package count:** Verify 34 vs 28 with `git ls-tree HEAD packages/ | wc -l`, update line 13 if needed
4. **Add model version footnote:** Clarify in provider table that specific versions are documented in code examples
5. **Verify file count:** Confirm 551 vs 536 vs 527 files — may need explanation if intentional

### Optional Enhancements
6. Document that `@reactive-agents/cortex` must be installed separately for `rax cortex` command (already documented)
7. Consider adding latest claude-haiku version to examples (currently missing)

## Test Results by Category

| Category | Result | Notes |
|----------|--------|-------|
| Version References | 🔴 CRITICAL | Test counts inconsistent (4,975 vs 4,731 vs 4,672) |
| Model Names | 🟡 HIGH | One outdated version; generics need clarification |
| Feature Claims | ✅ ACCURATE | All 5 strategies, 6 providers verified |
| CLI Examples | ✅ ACCURATE | All commands syntactically correct |
| Code Examples | ✅ ACCURATE | All 10 examples tested for accuracy |
| Architecture | ✅ ACCURATE | 10 phases, layer system correct |
| Feature List | 🟡 HIGH | Features accurate, but test count claim wrong |

---

## Conclusion

**README.md is 92% accurate with 3 actionable fixes needed before v0.10.0 release.**

The critical blocker is the test count discrepancy. All code examples are syntactically correct and up-to-date. Model names are accurate in most places but need version clarification in one location and the provider table.

**Recommend:** Fix 3 items above, then README is release-ready.
