Document Audit & Feature Extraction

Systematically inventory, evaluate, and extract structured data from document collections.

Audit Framework

Four-Phase Audit

Phase 1: Inventory    → What exists?
Phase 2: Classify     → What type is each document?
Phase 3: Evaluate     → What's the quality?
Phase 4: Extract      → What structured data can we pull?

Phase 1: Inventory

Automated Inventory

from pathlib import Path
from dataclasses import dataclass

@dataclass
class DocumentEntry:
    path: str
    name: str
    extension: str
    size_bytes: int
    modified: str
    word_count: int
    has_frontmatter: bool

def inventory_documents(root: str, patterns: list[str] = ["*.md", "*.txt", "*.yaml"]) -> list[DocumentEntry]:
    entries = []
    for pattern in patterns:
        for path in Path(root).rglob(pattern):
            content = path.read_text(errors="ignore")
            entries.append(DocumentEntry(
                path=str(path.relative_to(root)),
                name=path.stem,
                extension=path.suffix,
                size_bytes=path.stat().st_size,
                modified=path.stat().st_mtime,
                word_count=len(content.split()),
                has_frontmatter=content.startswith("---"),
            ))
    return entries

Inventory Report

## Document Inventory

| Path | Type | Words | Frontmatter | Modified |
|------|------|-------|-------------|----------|
| skills/dev/testing/SKILL.md | skill | 1,245 | Yes | 2026-03-20 |
| docs/CHANGELOG.md | changelog | 890 | No | 2026-03-19 |
| README.md | readme | 450 | No | 2026-03-18 |

**Total:** 142 documents | **With frontmatter:** 105 | **Total words:** 185,000

Phase 2: Classification

Document Type Taxonomy

| Type | Signal | Example | |------|--------|---------| | Skill | YAML frontmatter with name:, in skills/ | SKILL.md | | Configuration | YAML/JSON schema | seed.yaml, registry.json | | Guide | Tutorial structure, step-by-step | getting-started.md | | Reference | API docs, schema docs | api-spec.md | | Decision | ADR format, options + decision | adr-001.md | | Changelog | Date-ordered entries | CHANGELOG.md | | Policy | Rules, constraints | CONTRIBUTING.md |

Automated Classification

def classify_document(path: str, content: str) -> str:
    if "skills/" in path and content.startswith("---"):
        return "skill"
    if path.endswith("seed.yaml") or path.endswith("registry.json"):
        return "configuration"
    if "## Step" in content or "### Step" in content:
        return "guide"
    if "## Decision" in content or "## Alternatives" in content:
        return "decision"
    if "## [" in content and any(d in content for d in ["Added", "Fixed", "Changed"]):
        return "changelog"
    return "general"

Phase 3: Quality Evaluation

Quality Scorecard

| Criterion | Weight | Score (0-3) | Notes | |-----------|--------|-------------|-------| | Completeness | 30% | | All required sections present? | | Accuracy | 25% | | Information correct and current? | | Clarity | 20% | | Understandable without prior context? | | Structure | 15% | | Logical organization, headings, formatting? | | Maintenance | 10% | | Updated date, versioned, no stale links? |

Automated Quality Checks

def quality_check(path: str, content: str) -> dict:
    checks = {
        "has_title": content.startswith("#") or content.startswith("---"),
        "has_sections": content.count("\n##") >= 2,
        "reasonable_length": 100 < len(content.split()) < 10000,
        "no_todo_left": "TODO" not in content and "FIXME" not in content,
        "no_broken_links": not re.search(r'\[.*?\]\(\s*\)', content),
        "has_code_examples": "```" in content,
        "frontmatter_complete": check_frontmatter_fields(content),
    }
    score = sum(checks.values()) / len(checks)
    return {"checks": checks, "score": round(score, 2)}

Phase 4: Feature Extraction

Metadata Extraction

import yaml
import re

def extract_frontmatter(content: str) -> dict | None:
    match = re.match(r'^---\n(.*?)\n---', content, re.DOTALL)
    if match:
        return yaml.safe_load(match.group(1))
    return None

def extract_features(content: str) -> dict:
    return {
        "headings": re.findall(r'^#+\s+(.+)$', content, re.MULTILINE),
        "code_blocks": len(re.findall(r'```', content)) // 2,
        "links": re.findall(r'\[([^\]]+)\]\(([^)]+)\)', content),
        "images": re.findall(r'!\[([^\]]*)\]\(([^)]+)\)', content),
        "tables": content.count("\n|"),
        "todos": re.findall(r'- \[ \]\s+(.+)', content),
    }

Cross-Reference Mapping

def build_reference_graph(documents: list[dict]) -> dict:
    graph = {}
    for doc in documents:
        links = extract_features(doc["content"])["links"]
        graph[doc["path"]] = {
            "outgoing": [link[1] for link in links if not link[1].startswith("http")],
            "incoming": [],
        }

    # Build incoming links
    for source, data in graph.items():
        for target in data["outgoing"]:
            if target in graph:
                graph[target]["incoming"].append(source)

    return graph

Gap Analysis

def gap_analysis(inventory: list[dict], expected: dict) -> dict:
    existing = {doc["path"] for doc in inventory}
    gaps = {
        "missing_required": [p for p in expected.get("required", []) if p not in existing],
        "missing_recommended": [p for p in expected.get("recommended", []) if p not in existing],
        "orphaned": [p for p in existing if p not in expected.get("all_known", existing)],
        "empty_files": [doc["path"] for doc in inventory if doc["word_count"] < 10],
    }
    return gaps

Anti-Patterns

• Manual-only audits — Automate what you can; reserve human judgment for quality assessment
• Audit without action — Every finding should map to a remediation action
• One-time audit — Build continuous monitoring, not point-in-time snapshots
• Counting without evaluating — Document count is vanity; quality score is actionable
• No baseline — Establish quality benchmarks before auditing
• Ignoring cross-references — Orphaned documents and broken links indicate structural problems
