@unrdf/diataxis-kit

Diátaxis documentation kit for monorepo package inventory and deterministic doc scaffold generation. Automatically discovers all workspace packages and generates documentation scaffolds using the Diátaxis framework (Tutorials, How-to Guides, Reference, Explanation).

Features

• 🔍 Workspace Discovery: Automatically discovers 40+ packages from pnpm/yarn/npm workspaces
• 📊 Package Inventory: Generates inventory.json with metadata for all packages
• 🎯 Evidence Collection: Gathers evidence from README, docs/, examples/, src/, and package.json
• 📚 Diátaxis Classification: Classifies documentation into four types based on evidence
• 🔧 Deterministic Generation: Produces identical outputs across multiple runs with DETERMINISTIC=1
• ✅ Coverage Verification: Ensures all packages have required documentation stubs
• 📈 Coverage Reporting: Generates detailed coverage and confidence reports

Quick Start

# Generate inventory and scaffolds
pnpm run run

# Verify all packages have required documentation
pnpm run verify

# Generate coverage report
pnpm run report

# Run tests (determinism + inventory + verification)
pnpm test

How It Works

1. Discovery Phase (inventory.mjs)

Scans workspace configuration files and discovers all packages:

const packages = await discoverPackages('/path/to/workspace');
// Returns: [
//   { name, dir, version, exports, bin, keywords, hasReadme, hasDocs, hasExamples, ... }
// ]

2. Evidence Collection (evidence.mjs)

Gathers evidence from each package:

• README: Content and headings
• Examples: Files and snippets
• Docs: Directory listing and snippets
• Source: Top-level export files
• Package.json: Exports, bin entries, keywords
• Fingerprint: SHA256 hash of evidence

3. Classification (classify.mjs)

Classifies packages using evidence-based rules:

• Tutorials: Generated from examples/ and README "Getting Started" sections
• How-tos: Generated from README "Usage", "Configuration" sections and keywords
• Reference: Extracted from package.json exports/bin and README API sections
• Explanation: Generated from keywords, README intro, and docs/ presence

Each classification item includes:

• Title and description
• Confidence score (0-1) based on evidence strength
• Source tracking (which evidence contributed)

4. Scaffold Generation (scaffold.mjs)

Generates markdown files with:

• Frontmatter: Package name, version, generated timestamp, confidence score, proof hash
• Content: Sections specific to each Diátaxis type
• Proof block: SHA256 hash of evidence inputs
• Directory structure: tutorials/, how-to/, reference/, explanation/

5. Verification & Reporting

Verify (verify.mjs): Checks all packages have:

• At least 1 tutorial stub
• At least 2 how-to stubs
• Reference documentation
• Explanation documentation

Report (report.mjs): Generates coverage statistics:

• Total packages and documentation type coverage
• Confidence metrics (avg, min, max)
• Lowest confidence packages
• Missing evidence sources
• Quick fix suggestions

Determinism

Run with DETERMINISTIC=1 to ensure byte-identical outputs:

# First run
DETERMINISTIC=1 pnpm run run

# Second run produces identical artifacts
DETERMINISTIC=1 pnpm run run

# Hashes match: 100% determinism guaranteed
sha256sum ARTIFACTS/diataxis/inventory.json

Determinism guarantees:

• Fixed timestamps: 2000-01-01T00:00:00.000Z
• Stable JSON key ordering
• Lexicographic sorting of packages and documentation
• Identical SHA256 hashes across runs

Testing

# Run all tests
pnpm test

# Run determinism tests (2x pipeline execution)
pnpm run test:determinism

# Run inventory discovery tests
pnpm run test:inventory

# Run verification gate tests
pnpm run test:verify

# Clean artifacts before running tests
pnpm run clean

Test Coverage:

• Determinism Tests (4/4 passing):

  • Inventory and artifacts hashes match across runs
  • Timestamps fixed in deterministic mode
  • Stable ordering verified for all packages
  • Proof hashes valid and consistent

• Inventory Tests (7/7 passing):

  • 86 packages discovered (>= 42 required)
  • Required fields present and valid
  • Unique package names
  • Directory existence verified
  • Entry validation working

• Verification Tests (13/13 passing):

  • All packages pass coverage requirements
  • Missing tutorials detected
  • Missing how-tos detected
  • Missing reference detected
  • Missing explanation detected

pnpm run verify --fail-fast              # Exit on first failure
pnpm run verify --threshold 5            # Fail only if >5 packages fail
pnpm run verify --help                   # Show help

Exit codes:

• 0: All packages meet requirements
• 1: One or more packages fail requirements

diataxis-report (bin/report.mjs)

Coverage and confidence reporting:

# Generate coverage report
pnpm run report

# With options
pnpm run report --json                          # JSON output
pnpm run report --csv                          # CSV output
pnpm run report --top 10                       # Show top 10 packages
pnpm run report --filter "@unrdf/"            # Filter by keyword
pnpm run report --sort confidence             # Sort by confidence
pnpm run report --help                        # Show help

Implementation Details

Stable JSON Stringification

Keys are always sorted lexicographically:

const input = { b: 1, a: 2, arr: [2, 1] };
const output = stableStringify(input);
// Result: { "a": 2, "arr": [2, 1], "b": 1 }

Confidence Scoring

Each documentation type has specific confidence weights:

• Tutorials: +0.3 examples/, +0.3 README, +0.1 keywords
• How-tos: +0.25 README sections, +0.25 bin, +0.25 keywords, +0.25 tests
• Reference: +0.5 exports, +0.3 bin, +0.2 README API
• Explanation: +0.3 README, +0.3 docs/, +0.4 keywords

Evidence Fingerprinting

Each package's evidence is hashed to detect changes:

fingerprint = sha256(
  readmeHeadings.join('|') +
  examplesFiles.join('|') +
  docsFiles.join('|') +
  srcFiles.join('|') +
  keywords.join('|')
)

Constraints

• Node.js ESM only (.mjs files)
• No TypeScript (JSDoc for type hints)
• No external dependencies (except standard library)
• < 500 lines per file (enforced)
• 100% JSDoc coverage
• Zero entropy in deterministic mode

Performance

• Discovery: ~100ms for 86 packages
• Evidence collection: ~50ms per package
• Classification: ~30ms per package
• Scaffold generation: ~20ms per package
• Total: ~5-10 seconds for full monorepo

Future Improvements

• [ ] Cross-package relationship detection
• [ ] API surface diffing between versions
• [ ] Integration with documentation generators (Nextra, Vitepress)
• [ ] Custom classification rules per package
• [ ] Automated fix suggestions with git integration
