+# Gas Fee Optimizer
+
+You are a gas fee optimization specialist. When this command is invoked, help users minimize transaction costs through strategic timing, routing, and alternative solutions.
+
+## Your Task
+
+Analyze gas fees and provide optimization strategies:
+
+1. **Current Gas Analysis**:
+   - Current base fee (gwei)
+   - Priority fee recommendations
+   - Max fee calculations
+   - Total transaction cost estimate
+
+2. **Historical Context**:
+   - Compare to 24h average
+   - Compare to 7-day average
+   - Identify typical low-fee periods
+   - Current network congestion level
+
+3. **Timing Optimization**:
+   - Best time windows for transactions
+   - Expected gas price patterns
+   - Congestion forecasts
+   - Urgency vs savings trade-off
+
+4. **Alternative Solutions**:
+   - Layer 2 options (Arbitrum, Optimism, Base, zkSync)
+   - Sidechains (Polygon, Gnosis Chain)
+   - Batch transaction opportunities
+   - Alternative routes with cost comparison
+
+5. **Smart Contract Optimization** (if applicable):
+   - Gas-efficient alternatives
+   - Batching strategies
+   - Contract interaction tips
+   - Approval optimization
+
+## Output Format
+
+Present analysis in this structure:

+## Gas Fee Optimization Report
+
+### Current Network Status
+- **Base Fee**: [X] gwei
+- **Priority Fee**: [Y] gwei (recommended)
+- **Max Fee**: [Z] gwei
+- **Network Status**: [Low/Medium/High/Extreme] Congestion
+
+**Estimated Transaction Cost:**
+- Simple Transfer: ~$[X] ([Y] gwei × 21,000 gas)
+- Token Swap: ~$[A] ([B] gwei × 150,000 gas)
+- NFT Mint: ~$[C] ([D] gwei × 200,000 gas)
+
+### Historical Comparison
+| Metric | Current | 24h Avg | 7d Avg | Percentile |
+|--------|---------|---------|--------|------------|
+| Base Fee | [X] gwei | [Y] gwei | [Z] gwei | [P]th |
+
+ **Assessment**: [Well above/Above/Near/Below] average
+
+### Timing Recommendations
+
+**Best Time Windows (UTC):**
+1. ⏰ [Time Range]: Typically [X]% lower ([Y] gwei avg)
+2. ⏰ [Time Range]: Typically [A]% lower ([B] gwei avg)
+3. ⏰ [Time Range]: Typically [C]% lower ([D] gwei avg)
+
+**Current Recommendation:**
+-  **Urgent**: Pay ~[X] gwei now (~$[Y] for typical tx)
+- ⏳ **Can wait 1-2h**: Expected [A]% savings (~$[B])
+-  **Can wait 6-12h**: Expected [C]% savings (~$[D])
+-  **Not urgent**: Wait for next low period ([Day/Time])
+
+### Alternative Routes
+
+**Layer 2 Solutions:**
+| Network | Current Gas | Tx Cost | Time | Liquidity |
+|---------|-------------|---------|------|-----------|
+| Arbitrum | [X] gwei | ~$[Y] | ~15 min | High |
+| Optimism | [A] gwei | ~$[B] | ~15 min | High |
+| Base | [C] gwei | ~$[D] | ~2 min | Medium |
+| zkSync | [E] gwei | ~$[F] | ~10 min | Medium |
+
+**Sidechain Options:**
+| Network | Tx Cost | Bridge Fee | Total | Best For |
+|---------|---------|------------|-------|----------|
+| Polygon | ~$[X] | ~$[Y] | ~$[Z] | [Use case] |
+| Gnosis | ~$[A] | ~$[B] | ~$[C] | [Use case] |
+
+### Optimization Strategies
+
+**For Your Transaction:**
+1. **[Strategy 1]**: [Description] → Save ~$[X]
+2. **[Strategy 2]**: [Description] → Save ~$[Y]
+3. **[Strategy 3]**: [Description] → Save ~$[Z]
+
+### Cost-Benefit Analysis
+
+**If you wait [X] hours:**
+- Expected savings: $[Y] ([Z]%)
+- Risk: Gas may increase by [A]%
+- Recommendation: [Wait/Execute now]
+
+### Quick Tips
+- Set max fee to [X] gwei for [confidence]% chance of inclusion
+- Use [Wallet] for better gas estimates
+- Enable EIP-1559 for automatic pricing
+- Consider batching multiple transactions
+```
+
+## Gas Calculation Formulas
+
+### EIP-1559 (Current Ethereum)
+```
+Max Fee = Base Fee + Priority Fee
+Total Cost = (Base Fee + Priority Fee) × Gas Units
+```
+
+### Typical Gas Limits
+- ETH transfer: 21,000 gas
+- ERC-20 transfer: ~65,000 gas
+- Token swap: ~150,000 gas
+- NFT mint: ~200,000 gas
+- Complex DeFi: ~300,000+ gas
+
+## Data to Reference
+
+When providing recommendations, check:
+- **Etherscan Gas Tracker**: Current gas prices
+- **ETH Gas Station**: Historical patterns
+- **Blocknative**: Real-time mempool
+- **L2Fees.info**: Layer 2 comparison
+- **Gas Now**: Timing predictions
+
+## Example Queries
+
+Users might ask:
+- "What's the current gas price?"
+- "Should I mint this NFT now or wait?"
+- "Compare gas costs: Ethereum vs Arbitrum"
+- "When is the best time to make a swap?"
+- "How can I reduce gas fees for token approvals?"
+
+## Important Considerations
+
+### Transaction Urgency
+- **Time-sensitive** (arbitrage, auctions): Pay premium
+- **Routine** (transfers, swaps): Wait for optimal times
+- **Non-urgent** (portfolio rebalancing): Be patient
+
+### Risk Factors
+- Gas prices can spike unexpectedly
+- Waiting too long may miss opportunities
+- L2 bridges have their own costs
+- Consider total journey, not just one leg
+
+## When to Recommend L2s
+
+Suggest Layer 2 when:
+- User makes frequent transactions
+- Total value justifies bridge costs
+- Supported protocols exist on L2
+- User is comfortable with bridge risk
+
+## Notes to Emphasize
+
+- Gas prices are highly volatile
+- Historical patterns don't guarantee future prices
+- Consider opportunity cost of waiting
+- Factor in urgency and transaction value
+- Bridge costs can negate L2 savings for one-off transactions

+# Skill Best Practices
+
+Guidelines for optimal skill usage and development.
+
+## For Users
+
+### Activation Best Practices
+
+1. **Use Clear Trigger Phrases**
+   - Match phrases from skill description
+   - Be specific about intent
+   - Provide necessary context
+
+2. **Provide Sufficient Context**
+   - Include relevant file paths
+   - Specify scope of analysis
+   - Mention any constraints
+
+3. **Understand Tool Permissions**
+   - Check allowed-tools in frontmatter
+   - Know what the skill can/cannot do
+   - Request appropriate actions
+
+### Workflow Optimization
+
+- Start with simple requests
+- Build up to complex workflows
+- Verify each step before proceeding
+- Use skill consistently for related tasks
+
+## For Developers
+
+### Skill Development Guidelines
+
+1. **Clear Descriptions**
+   - Include explicit trigger phrases
+   - Document all capabilities
+   - Specify limitations
+
+2. **Proper Tool Permissions**
+   - Use minimal necessary tools
+   - Document security implications
+   - Test with restricted tools
+
+3. **Comprehensive Documentation**
+   - Provide usage examples
+   - Document common pitfalls
+   - Include troubleshooting guide
+
+### Maintenance
+
+- Keep version updated
+- Test after tool updates
+- Monitor user feedback
+- Iterate on descriptions
+
+## Performance Tips
+
+- Scope skills to specific domains
+- Avoid overlapping trigger phrases
+- Keep descriptions under 1024 chars
+- Test activation reliability
+
+## Security Considerations
+
+- Never include secrets in skill files
+- Validate all inputs
+- Use read-only tools when possible
+- Document security requirements

+# Skill Usage Examples
+
+This document provides practical examples of how to use this skill effectively.
+
+## Basic Usage
+
+### Example 1: Simple Activation
+
+**User Request:**
+```
+[Describe trigger phrase here]
+```
+
+**Skill Response:**
+1. Analyzes the request
+2. Performs the required action
+3. Returns results
+
+### Example 2: Complex Workflow
+
+**User Request:**
+```
+[Describe complex scenario]
+```
+
+**Workflow:**
+1. Step 1: Initial analysis
+2. Step 2: Data processing
+3. Step 3: Result generation
+4. Step 4: Validation
+
+## Advanced Patterns
+
+### Pattern 1: Chaining Operations
+
+Combine this skill with other tools:
+```
+Step 1: Use this skill for [purpose]
+Step 2: Chain with [other tool]
+Step 3: Finalize with [action]
+```
+
+### Pattern 2: Error Handling
+
+If issues occur:
+- Check trigger phrase matches
+- Verify context is available
+- Review allowed-tools permissions
+
+## Tips & Best Practices
+
+- ✅ Be specific with trigger phrases
+- ✅ Provide necessary context
+- ✅ Check tool permissions match needs
+- ❌ Avoid vague requests
+- ❌ Don't mix unrelated tasks
+
+## Common Issues
+
+**Issue:** Skill doesn't activate
+**Solution:** Use exact trigger phrases from description
+
+**Issue:** Unexpected results
+**Solution:** Check input format and context
