# 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
| Task | Tool | Why |
|------|------|-----|
| Content creation | AI | Creative, context-aware |
| Pattern detection | AI | Recognizes similarities |
| Schema validation | bash/grep | Fast, free, deterministic |
| Bulk updates | sed/awk/yq | Efficient, scriptable |
| Version control | git | Tracks changes over time |
**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

## 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
