Pattern-Driven Knowledge Bases with AI Assistance

A methodology for building scalable, consistent knowledge bases that leverage both AI creativity and programmatic efficiency.

The Core Insight

Traditional approach: Create files however, let chaos accumulate, manually organize later

Pattern-driven approach: Identify content patterns early, codify them as templates, enforce them programmatically

Result: Consistency without rigidity, automation without losing creative flexibility

The Three-Layer System

Layer 1: Content Patterns (Human Intelligence)

Analyze existing content to identify recurring structures:

• Feature Guides: What It Does → How to Use It → When to Use It → How It Works → Pro Tip
• Conceptual Explainers: Core Principle → How It Works → Examples → Misconceptions
• Workflow Guides: Prerequisites → Steps → Troubleshooting
• Troubleshooting Guides: Problem → Symptoms → Solution → Prevention

Why patterns matter:

• Readers know what to expect
• Writers have clear frameworks
• Content is scannable and predictable
• Quality remains consistent

Layer 2: AI-Assisted Creation (AI Intelligence)

Use AI agents to:

1. Detect which pattern fits the content being created
2. Apply the appropriate template structure
3. Propose new patterns when existing ones don't fit
4. Generate frontmatter with proper timestamps and metadata

What AI does well:

• Pattern matching and recognition
• Content generation within structure
• Detecting anomalies ("this doesn't fit any pattern")
• Proposing improvements

What AI shouldn't do:

• Validate 500 files (use bash scripts)
• Enforce schema compliance (use grep/yq)
• Bulk refactoring (use sed/awk)

Layer 3: Programmatic Enforcement (Machine Efficiency)

Use scripts and command-line tools to:

• Validate frontmatter schema
• Find files missing required fields
• Bulk update metadata
• Enforce section ordering
• Track validation status

Key enabler: Structured frontmatter

yaml
---
created: 2025-11-08T14:57:13-0800
slug: cl3l2tmhjp5
template_type: feature-guide       # ← Enables filtering by pattern
schema_validated: 2025-11-08       # ← Tracks validation status
---

Power move: Use template_type to:

bash
# Find all feature guides
grep -l "template_type: feature-guide" **/*.md

# Add new section to all workflow guides
for file in $(grep -l "template_type: workflow-guide" **/*.md); do
  # Programmatic update
done

How the Layers Work Together

Scenario: Creating a New Article

Step 1 (Human): "I need to document the Capture Recording feature in Logic"

Step 2 (AI):

• Recognizes this is a software feature
• Selects "Feature Guide" pattern
• Generates file with template structure
• Calculates frontmatter fields (timestamp, slug)
• Sets template_type: feature-guide

Step 3 (Programmatic):

• Validation script confirms all required fields present
• Git pre-commit hook checks schema compliance
• File appears in grep -l "template_type: feature-guide" queries

Step 4 (Human): Fills in content within the structure

Scenario: Schema Evolution

Trigger: "All gear guides should now include a manufacturer_url field"

Step 1 (Human): Update template in _templates/Gear Guide.md

Step 2 (Programmatic):

bash
# Find all gear guides
for file in $(grep -l "template_type: gear-guide" **/*.md); do
  # Add manufacturer_url after manufacturer field
  sed -i '' '/^manufacturer:/a\
manufacturer_url: 
' "$file"
done

Step 3 (AI):

• New articles automatically include manufacturer_url
• AGENTS.md documents the field requirement

Step 4 (Validation):

bash
# Verify all gear guides have the field
grep -l "template_type: gear-guide" **/*.md | xargs grep -L "manufacturer_url"
# Should return empty

Scenario: Discovering a New Pattern

Trigger: AI creates 3rd article with similar non-standard structure

Step 1 (AI): "This content doesn't fit existing patterns. Should we create Pattern 11: Comparison Matrix?"

Step 2 (Human): Reviews, confirms new pattern makes sense

Step 3 (Human): Documents pattern in pattern guide

Step 4 (Human): Creates template in _templates/

Step 5 (Programmatic): Retrospectively tags existing files:

bash
# Find files with comparison tables
grep -l "| Feature | Option A | Option B |" **/*.md
# Add template_type: comparison-matrix

Key Design Principles

1. Patterns Emerge, Don't Prescribe

Don't: Create 20 theoretical patterns upfront Do: Document patterns as they appear organically (3+ uses = document it)

Why: Premature abstraction creates unused patterns. Let content needs drive pattern creation.

2. Flexible Structure, Strict Metadata

Flexible: Content patterns are guidelines, not laws. Adapt when needed.

Strict: Frontmatter schema is enforced. Every file MUST have:

• created, updated, slug
• template_type, schema_validated

Why: Flexible content allows creativity. Strict metadata enables automation.

3. Right Tool for the Job

Anti-pattern: Using AI to iterate through 500 files to check frontmatter

4. Documentation as Code

Pattern definitions live in markdown files:

• AGENTS.md - Instructions for AI agents
• Article Structure Patterns.md - Detailed pattern documentation
• _templates/ - Executable templates

Benefits:

• Version controlled
• Searchable
• Self-documenting
• AI-readable

5. Validate On-Demand, Not Continuously

Don't: Track schema_version in every file Do: Track schema_validated date, run validation when needed

Why: Git already tracks schema evolution. Avoid redundant versioning.

When to validate:

• After schema changes
• Before publishing
• On-demand via validate-schema.sh

Implementation Guide

Phase 1: Pattern Discovery (Weeks 1-2)

1. Analyze 20-30 existing articles
2. Identify 3-5 recurring structures
3. Document patterns with examples
4. Create templates for each pattern

Deliverable: Pattern guide with template files

Phase 2: Schema Definition (Week 3)

1. Design frontmatter schema
2. Add template_type and schema_validated fields
3. Update templates with new schema
4. Document in AGENTS.md

Deliverable: Standardized frontmatter across templates

Phase 3: AI Integration (Week 4)

1. Train AI agents on pattern selection
2. Configure AI to calculate timestamps/slugs

2. Refine existing patterns based on usage
3. Update tooling as needs evolve
4. Document learnings

Real-World Benefits

Consistency at Scale

Before: 500 articles with varying structures, hard to navigate

After: 500 articles following 8 clear patterns, predictable and scannable

Efficient Bulk Operations

Before: "I need to add a field to all gear guides" → manually edit 50 files

After: One-line bash script updates all 50 files in seconds

AI Compute Savings

Before: AI validates every file on every run → expensive, slow

After: AI creates content, scripts validate → cheap, fast

Pattern Evolution

Before: New content types = chaos

After: New patterns emerge, get documented, become reusable

Collaborative Authoring

Before: Each contributor writes differently

After: Templates guide consistent structure, easier to review/edit

Common Pitfalls

Over-Patterning

Symptom: 30 hyper-specific patterns that are rarely used

Fix: Merge similar patterns, wait for 3+ uses before documenting

Schema Bloat

Symptom: Frontmatter with 20+ fields, most unused

Fix: Only add fields that serve a clear purpose (filtering, tracking, automation)

AI Over-Reliance

Symptom: Using AI for tasks bash does instantly

Fix: Profile your workflows - use the right tool for each job

Rigid Enforcement

Symptom: Rejecting good content because it doesn't fit a pattern

Fix: Patterns are guidelines. When content truly needs different structure, create a new pattern or make a one-off
