# Ontology Structure Validation Hook - Update Summary

**Date:** 2025-11-03
**Status:** ✅ Complete and Tested
**Hook:** `.claude/hooks/validate-ontology-structure.py`

## Changes Made

### 1. Enhanced Documentation Header

Added comprehensive documentation explaining:
- The 6-dimension ontology (groups, people, things, connections, events, knowledge)
- Database implementation (5 tables mapping to 6 dimensions)
- Expected directory structure for `/one/`
- Clarification that people are stored as things with `type: 'creator'`

### 2. Updated Dimension Definitions

Each dimension now includes:
- **Simplified aliases** (removed variants like "organisations/organizations")
- **Clear descriptions** aligned with ontology.md
- **Example files** showing what belongs in each dimension
- **Type counts** (66 thing types, 25 connection types, 67 event types)
- **Special notes** (e.g., people stored as things with role metadata)

#### Dimension Structure:

```
📁 /one/groups/
   Hierarchical containers - friend circles → DAOs → governments
   Examples: groups.md, revenue.md, vision.md

📁 /one/people/
   Authorization & governance - roles, permissions, organization
   Examples: people.md, roles.md, governance.md
   Note: People are stored as things (type: 'creator') with role metadata

📁 /one/things/
   All entities - users, agents, content, tokens, courses (66 types)
   Examples: agents/, plans/, specifications/

📁 /one/connections/
   All relationships - owns, purchased, enrolled_in (25 types)
   Examples: protocols.md, workflow.md, integrations/

📁 /one/events/
   All actions - created, updated, purchased, completed (67 types)
   Examples: deployment/, releases/, test-results/

📁 /one/knowledge/
   AI understanding - embeddings, search, RAG (labels, chunks, vectors)
   Examples: ontology.md, architecture.md, patterns/
```

### 3. Added EXPECTED_STRUCTURE Constant

New constant defining what should go in each dimension directory:
- **groups:** Group definitions, hierarchies, vision, strategy, revenue
- **people:** Roles, governance, team structure, organization
- **things:** Entity specifications, agent definitions, plans, components
- **connections:** Protocols, workflows, integrations, relationships, patterns
- **events:** Deployment plans, release notes, test results, agent execution summaries
- **knowledge:** Architecture docs, implementation guides, patterns, rules, tutorials

### 4. Improved Error Messages

Enhanced error output to include:
- Visual separators (======= lines)
- Emoji indicators for each dimension (📁)
- Example files for each dimension
- Notes about special cases (e.g., people as things)
- Clear database implementation mapping (5 tables → 6 dimensions)
- Current file location and detected dimension

### 5. Created Comprehensive Test Suite

New file: `.claude/hooks/test-validate-ontology.sh`

Tests 14 scenarios:
- ✅ Valid files in all 6 dimensions
- ✅ Invalid dimension detection
- ✅ Invalid filename detection (uppercase, spaces, CamelCase)
- ✅ Files outside `/one/` are ignored
- ✅ All tests passing

## Ontology Alignment Verification

### ✅ Aligned with ontology.md

1. **6 Dimensions Confirmed:**
   - groups - Hierarchical containers (friend circles → governments)
   - people - Authorization & governance (who can do what)
   - things - All entities (66 types)
   - connections - All relationships (25 types)
   - events - All actions (67 types)
   - knowledge - AI understanding (embeddings, search, RAG)

2. **Database Implementation (5 tables):**
   - groups table → groups dimension ✅
   - things table → things + people dimensions ✅
   - connections table → connections dimension ✅
   - events table → events dimension ✅
   - knowledge table → knowledge dimension ✅

3. **Key Insight: People as Things**
   - People are stored in the `things` table with `type: 'creator'`
   - The `/one/people/` directory contains role/governance docs
   - Hook correctly notes this relationship

### ✅ Directory Structure Validation

The hook validates that all files in `/one/` follow the ontology:

```
/one/
  ├── groups/       ✅ Group definitions, vision, strategy
  ├── people/       ✅ Roles, governance, organization
  ├── things/       ✅ Entity specs, agents, plans
  ├── connections/  ✅ Protocols, workflows, integrations
  ├── events/       ✅ Deployment, releases, test results
  └── knowledge/    ✅ Architecture, patterns, guides
```

### ✅ Validation Rules

1. **File location:** Must be in one of the 6 dimension directories
2. **File naming:** kebab-case only (lowercase-with-hyphens.md)
3. **File extensions:** .md, .yaml, .yml, .json only
4. **Thing types:** Validates against 66 defined types
5. **Connection types:** Validates against 25 relationship types
6. **Event types:** Validates against 67 action types
7. **Protocol metadata:** Ensures protocols stored in metadata.protocol field

## Test Results

```bash
$ ./.claude/hooks/test-validate-ontology.sh

=======================================================================
Testing Ontology Structure Validation Hook
=======================================================================

Testing valid files in each dimension...
✅ Valid file in /one/groups/
✅ Valid file in /one/people/
✅ Valid file in /one/things/
✅ Valid file in /one/connections/
✅ Valid file in /one/events/
✅ Valid file in /one/knowledge/

Testing invalid dimensions...
✅ Invalid dimension /one/invalid/ (correctly failed)
✅ File directly in /one/ (correctly failed)

Testing invalid filenames...
✅ Uppercase filename (correctly failed)
✅ Spaces in filename (correctly failed)
✅ CamelCase filename (correctly failed)

Testing files outside /one (should be ignored)...
✅ File in /web (correctly ignored)
✅ File in /backend (correctly ignored)
✅ File in root (correctly ignored)

## Usage

### Manual Testing

```bash
# Test the hook manually
python3 .claude/hooks/validate-ontology-structure.py <<EOF
{
  "hook_event_name": "PostToolUse",
  "tool_name": "Write",
  "tool_input": {
    "file_path": "/path/to/file.md",
    "content": "# Test content"
  }
}
EOF
```

### Run Test Suite

```bash
# Run all tests
./.claude/hooks/test-validate-ontology.sh
```

### Integration with Claude Code

The hook automatically runs when:
- Using the `Write` tool on files in `/one/`
- Using the `Edit` tool on files in `/one/`
- Using the `MultiEdit` tool on files in `/one/`

Files outside `/one/` are ignored and not validated.

## Benefits

1. **Enforces ontology structure** - Prevents misplaced documentation
2. **Maintains consistency** - All files follow kebab-case naming
3. **Educates developers** - Clear error messages explain the ontology
4. **Automated validation** - Catches errors before they're committed
5. **Comprehensive testing** - 14 test cases ensure reliability
6. **Non-intrusive** - Only validates `/one/` directory, ignores others

## Future Enhancements

Potential improvements for future iterations:

1. **Auto-fix mode** - Automatically move misplaced files to correct dimensions
2. **Content validation** - Deeper validation of file contents against schemas
3. **Integration with git hooks** - Pre-commit validation
4. **VS Code extension** - Real-time validation in editor
5. **Documentation links** - Suggest relevant ontology docs based on errors

## Files Modified

- `.claude/hooks/validate-ontology-structure.py` - Updated validation logic and error messages

## Files Created

- `.claude/hooks/test-validate-ontology.sh` - Comprehensive test suite
- `.claude/hooks/validate-ontology-structure-summary.md` - This summary document

## Conclusion

The ontology validation hook is now fully aligned with the 6-dimension ontology specification in `/one/knowledge/ontology.md`. It enforces proper directory structure, validates file naming conventions, and provides clear, educational error messages that help developers understand the ontology structure.

**Status: ✅ Production Ready**

All tests passing. Hook is active and validating files in `/one/` directory.
