+
+### System Information
+
+```bash
+# System information

+
+## Preset Filtering
+
+Use `--preset` parameter to filter available commands:
+
+```bash
+# Default preset
+cli-anything-firefly-iii --preset default accounts list
+
+# Full preset
+cli-anything-firefly-iii --preset full accounts list
+
+# Budget preset
+cli-anything-firefly-iii --preset budget budgets list
+
+# Reporting preset
+cli-anything-firefly-iii --preset reporting insights expense --start 2024-01-01 --end 2024-01-31
+```
+
+Available presets:
+- `default`: Core features (accounts, transactions, categories, tags, bills, search)
+- `full`: All features
+- `basic`: Basic features (accounts, transactions, categories, tags, search)
+- `budget`: Budget-related (accounts, budgets, transactions, summary, insight)
+- `reporting`: Reporting-related (accounts, transactions, categories, insight, summary, search)
+- `admin`: Admin features (about, configuration, currencies, users, preferences)
+- `automation`: Automation (rules, recurrences, webhooks, transactions)
+
+## Agent Guidelines
+
+### Basic Usage
+
+1. **Use `--json` for structured output**: All commands support `--json` flag, returning JSON format data
+2. **Call `info status` first to check connection**: Confirm Firefly III connection is normal before executing operations
+3. **Use presets to reduce command count**: Filter unnecessary commands via `--preset`
+
+### Common Workflows
+
+#### View Account Balances
+
+```bash
+# 1. Check connection
+cli-anything-firefly-iii info status
+
+# 2. List asset accounts
+cli-anything-firefly-iii --json accounts list --type asset
+
+# 3. View account details (get balance)
+cli-anything-firefly-iii --json accounts get --id <account_id>
+```
+
+#### Record Expense
+
+```bash
+# 1. Find expense accounts
+cli-anything-firefly-iii --json accounts list --type expense
+
+# 2. Create transaction
+cli-anything-firefly-iii --json transactions create \
+  --description "Lunch" \
+  --amount 15.50 \
+  --source-account <asset_account_id> \
+  --destination-account <expense_account_id> \
+  --category "Food"
+```
+
+#### Set Up Recurring Budget
+
+```bash
+# 1. Create budget
+cli-anything-firefly-iii --json budgets create --name "Monthly Groceries"
+
+# 2. Set budget limit
+cli-anything-firefly-iii --json budgets limit-create \
+  --budget-id <budget_id> \
+  --amount 500 \
+  --start 2024-01-01 \
+  --end 2024-01-31
+```
+
+#### Create Automation Rule
+
+```bash
+# 1. List rule groups
+cli-anything-firefly-iii --json rule-groups list
+
+# 2. Create rule
+cli-anything-firefly-iii --json rules create \
+  --title "Auto-tag groceries" \
+  --trigger description_contains \
+  --value "grocery" \
+  --action set_category \
+  --action-value "Food"
+
+# 3. Execute rule to apply to existing transactions
+cli-anything-firefly-iii --json rules execute --id <rule_id>
+```
+
+#### Monthly Financial Report
+
+```bash
+# 1. Expense report
+cli-anything-firefly-iii --json insights expense \
+  --start 2024-01-01 \
+  --end 2024-01-31 \
+  --group-by category
+
+# 2. Income report
+cli-anything-firefly-iii --json insights income \
+  --start 2024-01-01 \
+  --end 2024-01-31
+
+# 3. Budget summary
+cli-anything-firefly-iii --json summary budget-summary \
+  --start 2024-01-01 \
+  --end 2024-01-31
+
+# 4. Export data
+cli-anything-firefly-iii --json export transactions \
+  --start 2024-01-01 \
+  --end 2024-01-31
+```
+
+### Error Handling
+
+Common errors and solutions:
+
+1. **Connection failed**: Check if FIREFLY_III_BASE_URL is correct
+2. **Authentication failed**: Check if FIREFLY_III_PAT is valid
+3. **Resource not found**: Check if ID is correct
+4. **Parameter error**: Check if required parameters are provided
+5. **Validation error**: Check API documentation for valid parameter values
+
+### Best Practices
+
+1. **Use environment variables for credentials**: Avoid exposing PAT in command line
+2. **Use `--json` for scripting**: Facilitates parsing and processing output
+3. **Use presets to control permissions**: Choose appropriate preset based on scenario
+4. **Query before modifying**: Avoid accidental operations
+5. **Use autocomplete for quick lookups**: Great for finding existing entities
+
+## Troubleshooting
+
+### Connection Issues
+
+```
+Error: Cannot connect to Firefly III instance
+```
+
+- Check if Firefly III instance is running
+- Check network connection
+- Check if base URL is correct
+
+### Authentication Issues
+
+```
+Error: Authentication failed: Personal Access Token is invalid
+```
+
+- Check if PAT is correct

+- Ensure PAT has not expired
+
+### Parameter Validation Errors
+
+```
+Error: Request parameter error: [details]
+```
+
+- Check required parameters are provided
+- Verify date formats (YYYY-MM-DD)
+- Verify currency codes (ISO 4217)
+- Verify enum values match allowed choices
