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

Full pattern list: fabric --list or https://github.com/danielmiessler/fabric/tree/main/patterns

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
