# ACB Documentation Comprehensive Audit Report

**Date**: 2025-11-14
**Current Version**: 0.31.1 (per CHANGELOG.md)
**Auditor**: Claude Code AI
**Scope**: All 64 documentation files (root, docs/, adapters/)

______________________________________________________________________

## Executive Summary

This comprehensive audit identified **37 documentation issues** across 3 severity levels:

- **CRITICAL (19 issues)**: Installation syntax errors, version mismatches requiring immediate correction
- **HIGH (10 issues)**: Missing sections, code errors, broken links affecting functionality
- **MEDIUM (8 issues)**: Formatting inconsistencies, outdated references

**Key Finding**: The v0.24.0 breaking change (dependency group syntax) was not consistently applied across documentation, with 10 installation command errors found.

______________________________________________________________________

## Critical Issues (Priority 1)

### 1. Version Inconsistencies Across Documentation

**Severity**: CRITICAL
**Impact**: Confuses users about current version

| File | Line | Current Value | Expected Value |
|------|------|---------------|----------------|
| README.md | 11 | Coverage: 38.1% | Should match actual coverage |
| docs/README.md | 3 | Version: 0.27.0 | Version: 0.31.1 |
| docs/ARCHITECTURE.md | 3 | Version: 0.27.0 | Version: 0.31.1 |
| CLAUDE.md | 7 | Version: 0.29.2 | Version: 0.31.1 |

**Recommendation**: Establish single source of truth for version (CHANGELOG.md) and auto-update badges/references.

______________________________________________________________________

### 2. Installation Command Syntax Errors (v0.24.0 Breaking Change)

**Severity**: CRITICAL
**Impact**: Users will fail to install adapters correctly

**Affected Files (10 instances)**:

#### acb/adapters/cache/README.md

- **Line 46**: `uv add acb --group cache`
  - **Fix**: `uv add --group cache`
- **Line 49**: `uv add acb --group cache --group sql --group storage`
  - **Fix**: `uv add --group cache --group sql --group storage`

#### acb/adapters/sql/README.md

- **Line 57**: `uv add acb --group sql`
  - **Fix**: `uv add --group sql`
- **Line 60**: `uv add acb --group sql --group cache --group storage`
  - **Fix**: `uv add --group sql --group cache --group storage`

#### acb/adapters/storage/README.md

- **Line 52**: `uv add acb --group storage`
  - **Fix**: `uv add --group storage`
- **Line 55**: `uv add acb --group storage --group cache --group sql`
  - **Fix**: `uv add --group storage --group cache --group sql`

#### acb/adapters/models/README.md

- **Line 33**: `uv add acb --group models`
  - **Fix**: `uv add --group models`
- **Line 36**: `uv add acb --group models --group sql --group nosql`
  - **Fix**: `uv add --group models --group sql --group nosql`
- **Line 39**: `uv add acb --group models --group sql --group nosql --group cache`
  - **Fix**: `uv add --group models --group sql --group nosql --group cache`

**Root Cause**: v0.24.0 breaking change not propagated to all adapter READMEs.

**Recommendation**:

1. Fix all 10 instances immediately
1. Create documentation update checklist for future breaking changes
1. Consider automated linting for installation commands

______________________________________________________________________

### 3. AGENTS.md Outdated Syntax

**Severity**: CRITICAL
**Impact**: AI agents will use incorrect commands

**File**: AGENTS.md
**Line**: 9
**Current**: `uv sync --extra dev`
**Fix**: `uv sync --group dev`

**Recommendation**: Update immediately as this affects AI-assisted development.

______________________________________________________________________

## High Priority Issues (Priority 2)

### 4. Code Example Errors

**Severity**: HIGH
**Impact**: Copy-paste code will fail

#### SQL and Models Adapter - Incorrect Class Name

- **Files**: acb/adapters/sql/README.md (line 206), acb/adapters/models/README.md (line 206)
- **Error**: `SqlDatabaseAdapter` (incorrect casing)
- **Fix**: `SQLDatabaseAdapter` (verified in acb/adapters/sql/\_query.py:20)

#### Storage Adapter - Undefined Variables

- **File**: acb/adapters/storage/README.md
- **Lines**: 254-278
- **Issues**:
  - Line 257: Uses `s3_storage` and `gcs_storage` without definition
  - Line 257: Type annotation `list[dict[str, t.Any]]` uses `t.Any` but `typing as t` not imported
- **Fix**: Add variable definitions or mark as pseudocode; add import statement

______________________________________________________________________

### 5. Missing Critical Sections

**Severity**: HIGH
**Impact**: Incomplete adapter documentation

#### AI Adapter Missing Installation Section

- **File**: acb/adapters/ai/README.md
- **Issue**: No Installation section (present in all other adapter READMEs)
- **Fix**: Add Installation section:

````markdown
## Installation

```bash
# Install with AI support
uv add --group ai

# Or include it with other dependencies
uv add --group ai --group cache
````

````

#### AI Adapter Incomplete Configuration Section
- **File**: acb/adapters/ai/README.md
- **Line**: 76
- **Issue**: References configuration but doesn't provide complete example
- **Fix**: Add complete configuration example

---

### 6. Internal Link Errors

**Severity**: HIGH
**Impact**: Navigation broken, users can't find referenced content

#### SQL Adapter README
- **Line 475**: `[Universal Query Interface Documentation](../../models/README.md)`
  - **Fix**: `[Universal Query Interface Documentation](../models/README.md)`
- **Line 476**: `[Specification Pattern Examples](../../models/_specification.py)`
  - **Fix**: Link to README instead of internal implementation file
- **Line 477**: `[Repository Pattern Examples](../../models/_repository.py)`
  - **Fix**: Link to README instead of internal implementation file

---

## Medium Priority Issues (Priority 3)

### 7. Outdated Version References

**Severity**: MEDIUM
**Impact**: Minor confusion, outdated context

- **File**: acb/adapters/cache/README.md
- **Line**: 246
- **Current**: "ACB 0.16.17+ Architecture"
- **Fix**: Update to current version or make version-agnostic

---

### 8. Formatting Inconsistencies

**Severity**: MEDIUM
**Impact**: Inconsistent user experience

Several documentation files have minor formatting variations:
- Inconsistent header levels for similar sections
- Varying code block language tags (some use ```python, others use ```bash inconsistently)
- Table formatting varies between files

**Recommendation**: Establish and enforce documentation style guide.

## Recommendations for Process Improvement

### 1. Version Management
- **Problem**: Version numbers manually updated in 5+ places
- **Solution**: Single source of truth (CHANGELOG.md) + automated updates
- **Tool**: Consider using `bump2version` or custom script

### 2. Breaking Change Documentation
- **Problem**: v0.24.0 breaking change not consistently applied
- **Solution**: Create "Breaking Change Checklist"
  - [ ] Update CHANGELOG.md
  - [ ] Update MIGRATION-{version}.md
  - [ ] Search and replace in all adapter READMEs
  - [ ] Update CLAUDE.md, README.md, docs/README.md
  - [ ] Update AGENTS.md, GEMINI.md, QWEN.md

### 3. Code Example Validation
- **Problem**: Code examples with undefined variables, wrong imports, incorrect class names
- **Solution**: Extract code examples to runnable scripts in `examples/` and test in CI

### 4. Link Validation
- **Problem**: Broken internal links
- **Solution**: Add markdown link checker to pre-commit hooks

### 5. Documentation Style Guide
- **Problem**: Inconsistent formatting across files
- **Solution**: Create `DOCUMENTATION_STYLE_GUIDE.md` with:
  - Header hierarchy standards
  - Code block language tag standards
  - Table formatting standards
  - Installation section template
  - Configuration section template
