tomevault-io Fabric Skill
AI-powered text processing using danielmiessler/fabric patterns with local Ollama inference.
Overview
| Aspect | Description |
|---|---|
| Purpose | Run pre-built AI prompt patterns for logs, code review, commit messages |
| Backend | Local Ollama (qwen2.5:32b primary, qwen2.5:7b-instruct fallback) |
| Pattern | Capability Layering - thin wrapper over existing CLI scripts |
| Cost | Free (local inference) |
Quick Actions
| Need | Action | Command |
|---|---|---|
| Analyze logs | AI analysis of Docker container logs | /fabric:analyze-logs <container> |
| Commit message | Generate from staged changes | /fabric:commit-msg |
| Code review | AI-powered code review | /fabric:review-code <file> |
| List patterns | See all 234 available patterns | /fabric patterns |
| Run any pattern | Execute arbitrary pattern | /fabric run <pattern> |
Commands
/fabric:analyze-logs
Analyze Docker container logs for patterns, anomalies, and recommendations.
/fabric:analyze-logs prometheus # Last 50 lines
/fabric:analyze-logs nginx --lines 200 # More context
/fabric:analyze-logs n8n --since 1h # Recent logs only
Output sections: Overview, Key Observations, Patterns/Anomalies, Recommendations
/fabric:commit-msg
Generate conventional commit messages from git diffs.
/fabric:commit-msg # From staged changes
/fabric:commit-msg --all # From all changes
Output format: <type>: <description> with change list
/fabric:review-code
AI-powered code review with prioritized recommendations.
/fabric:review-code src/server.ts # Single file
/fabric:review-code --staged # Staged changes
Output sections: Overall Assessment, Prioritized Recommendations, Detailed Feedback
/fabric patterns
List all available Fabric patterns.
/fabric patterns # List all 234 patterns
/fabric patterns --search log # Filter by keyword
/fabric run
Run any Fabric pattern directly.
echo "text" | /fabric run extract_wisdom
/fabric run summarize --file document.md
Architecture
This skill follows the Capability Layering Pattern:
Layer 5: USER REQUEST
"analyze the prometheus logs"
↓
Layer 4: PROMPT (this skill)
Routes to correct script
↓
Layer 3: CLI
Scripts/fabric-analyze-logs.sh prometheus
↓
Layer 2: CODE
fabric-wrapper.sh → fabric CLI → Ollama
↓
Layer 1: INFRASTRUCTURE
Ollama service (localhost:11434)
Scripts (Layer 3)
| Script | Purpose |
|---|---|
Scripts/fabric-wrapper.sh |
Core wrapper with health checks, model fallback |
Scripts/fabric-analyze-logs.sh |
Log analysis for Docker/files |
Scripts/fabric-commit-msg.sh |
Commit message generation |
Scripts/fabric-review-code.sh |
Code review |
Features Built Into Scripts
- Ollama Health Check: Auto-restarts Ollama if unresponsive
- Model Fallback: 32b → 7b on timeout (configurable)
- Streaming Output: Real-time results
- Error Handling: Clear error messages
Configuration
Environment Variables
| Variable | Default | Description |
|---|---|---|
FABRIC_PRIMARY_MODEL |
qwen2.5:32b |
Primary model for analysis |
FABRIC_FALLBACK_MODEL |
qwen2.5:7b-instruct |
Fallback on timeout |
FABRIC_TIMEOUT_PRIMARY |
90 |
Timeout in seconds for primary |
FABRIC_TIMEOUT_FALLBACK |
120 |
Timeout for fallback |
OLLAMA_URL |
http://localhost:11434 |
Ollama API endpoint |
Model Selection Guide
| Task | Recommended Model | Reason |
|---|---|---|
| Log analysis | 32b (default) | Benefits from deep reasoning |
| Commit messages | 7b | Fast, simple task |
| Code review | 7b (default) | Good balance of speed/quality |
| Complex analysis | 32b | Use --model 32b flag |
Patterns Reference
Fabric includes 234 patterns. Most useful for this infrastructure:
| Pattern | Use Case | Value |
|---|---|---|
analyze_logs |
Docker/service troubleshooting | HIGH |
summarize_git_diff |
Commit messages | HIGH |
review_code |
Code review | HIGH |
extract_wisdom |
Document summarization | MEDIUM |
create_design_document |
Technical specs | MEDIUM |
analyze_threat_report |
Security analysis | MEDIUM |

Troubleshooting
Ollama Not Responding
The wrapper auto-restarts Ollama, but if issues persist:
# Check Ollama status
systemctl status ollama
# Restart manually
sudo systemctl restart ollama
# Check models available
ollama list
Model Timeout
For large inputs, increase timeout:
FABRIC_TIMEOUT_PRIMARY=180 fabric-analyze-logs.sh prometheus --lines 500
Or force the faster model:
fabric-analyze-logs.sh prometheus --model 7b
Pattern Not Found
Update fabric patterns:
fabric --update
