Step 1/4 in portfolio_balancer workflow

Daily Permanent Portfolio analysis with allocation drift and rebalancing recommendations

Instructions

Goal: Gather current portfolio positions, values, and prices from Robinhood using bin/robinhood CLI

Collect Portfolio Data

Objective

Gather current portfolio positions, values, and prices from Robinhood to create a complete snapshot for Permanent Portfolio analysis.

Task

Collect all portfolio data needed to analyze the Permanent Portfolio allocation using the bin/robinhood CLI.

Process

1. Ask structured questions to gather user inputs Use the AskUserQuestion tool to collect:

   • drift_threshold: Percentage that triggers rebalancing (e.g., 5 or 10)
   • satellite_enabled: Whether to track satellite stock picks separately

2. Collect portfolio data using the Robinhood CLI

   Run the positions command to save today's snapshot:

   bin/robinhood positions --save
   

   This command is idempotent - it will skip if today's snapshot already exists. Use --force to overwrite an existing snapshot.

   If not authenticated, prompt user to run bin/robinhood auth first.

   Snapshot location: portfolio_balancer/data/snapshots/YYYY-MM-DD.json

   Fallback: Manual Upload If the CLI is unavailable, ask for a Robinhood export file (CSV or PDF).

   Note: Chrome extension browser automation is NOT supported - Robinhood blocks automated access.

3. Categorize holdings into Permanent Portfolio asset classes

   • Stocks: Individual stocks, stock ETFs (e.g., VTI, SPY, VOO)
   • Long-Term Bonds: Bond ETFs with long duration (e.g., TLT, VGLT, EDV)
   • Gold: Gold ETFs or holdings (e.g., GLD, IAU, SGOL)
   • Cash/Treasuries: Cash balance, money market, short-term treasuries (e.g., SHV, BIL)

4. Identify satellite positions (if enabled) If satellite_enabled is true, identify individual stock picks within the Stocks allocation that are not broad index funds.

5. Capture margin information

   • Current margin balance (if using margin)
   • Monthly margin fees/interest rate
   • Available margin

6. Create portfolio snapshot Output all collected data in structured YAML format.

Output Format

portfolio_balancer/data/portfolio_snapshot.yml

Quality Criteria

• All four asset classes are represented (even if value is 0)
• Each position has symbol, name, and value at minimum
• Total portfolio value equals sum of all asset class values
• Margin information captured if margin is being used
• Satellite positions identified if satellite_enabled is true
• Data source and timestamp recorded
• Drift threshold stored for use in subsequent steps
• YAML is valid and parseable
• When all criteria are met, include <promise>✓ Quality Criteria Met</promise> in your response

Context

This is the data collection foundation for Permanent Portfolio analysis. The quality and completeness of this snapshot directly impacts the accuracy of allocation analysis and rebalancing recommendations. Harry Browne's Permanent Portfolio requires equal 25% allocations across stocks, long-term bonds, gold, and cash/treasuries - this step must capture all holdings to enable that analysis.

Important: This system is READ-ONLY. We are only collecting data for analysis, not executing any trades.

Job Context

Automated daily portfolio analysis implementing Harry Browne's Permanent Portfolio strategy.

The Permanent Portfolio maintains equal 25% allocations across four asset classes designed to perform in different economic conditions:

• Stocks (25%): Prosperity/Growth
• Long-Term Bonds (25%): Deflation/Recession
• Gold (25%): Inflation
• Cash/Treasuries (25%): Tight Money/Recession

This workflow:

1. Collects portfolio data via bin/robinhood positions --save CLI
2. Analyzes current allocation against 25/25/25/25 targets
3. Tracks satellite stock picks (optional 10-20% of stock allocation)
4. Evaluates margin usage efficiency vs fees paid
5. Generates rebalancing recommendations when drift exceeds user-defined threshold
6. Produces a human-readable daily report for manual review

IMPORTANT: This system is read-only. No trades are executed automatically. All recommendations require manual review and execution.

Required Inputs

User Parameters - Gather from user before starting:

• drift_threshold: Percentage drift that triggers rebalancing recommendations (e.g., 5 or 10)
• satellite_enabled: Whether to track satellite stock picks separately (true/false)

Work Branch

Use branch format: deepwork/portfolio_balancer-[instance]-YYYYMMDD

• If on a matching work branch: continue using it
• If on main/master: create new branch with git checkout -b deepwork/portfolio_balancer-[instance]-$(date +%Y%m%d)

Outputs

Required outputs:

• portfolio_balancer/data/snapshots/[DATE].json
• portfolio_balancer/data/portfolio_snapshot.yml

Guardrails

• Do NOT skip prerequisite verification if this step has dependencies
• Do NOT produce partial outputs; complete all required outputs before finishing
• Do NOT proceed without required inputs; ask the user if any are missing
• Do NOT modify files outside the scope of this step's defined outputs

On Completion

1. Verify outputs are created
2. Inform user: "Step 1/4 complete, outputs: portfolio_balancer/data/snapshots/[DATE].json, portfolio_balancer/data/portfolio_snapshot.yml"
3. Continue workflow: Use Skill tool to invoke /portfolio_balancer.analyze_allocation
