•Discover your PocketSmith account structure
•Recommend and apply a rule template
•Help customize rules for your needs
•Configure intelligence modes
•Incrementally categorize transactions
•Show measurable improvement with health scores
•Provide ongoing usage guidance
•Generate intelligent suggestions

Time required: 30-60 minutes for first-time setup

Daily Usage

Two Usage Modes:

•
Guided Journey Mode - When you start Claude Code, Agent Smith displays a status dashboard with:
- •Your health score
- •Uncategorized transaction count
- •Conflicts awaiting review
- •Suggested next steps with both natural language and command options
•
Power User Mode - Use slash commands directly for specific operations.

Slash Commands (7 specialized commands):

•/smith:install - Installation and onboarding wizard
•/smith:categorize [--mode] [--period] - Transaction categorization
•/smith:review-conflicts - Review transactions flagged for review
•/smith:health [--full|--quick] - Health check and recommendations
•/smith:insights <spending|trends|scenario|report> - Financial analysis and reports
•/smith:tax <deductions|cgt|bas|eofy> - Tax intelligence (ATO)
•/smith:schedule [--setup|--status|--remove] - Automated categorization scheduling

Python Scripts

All Python scripts are in scripts/ directory. Always run with uv run python -u for proper dependency resolution and unbuffered output.

Core Operations

bash

# Categorize transactions
uv run python -u scripts/operations/batch_categorize.py --mode=smart --period=2025-11

# Run health check
uv run python -u scripts/health/check.py --full

# Generate spending report
uv run python -u scripts/reporting/generate.py --period=2025 --format=all

# Tax deduction analysis
uv run python -u scripts/tax/deduction_detector.py --period=2024-25

Script Organization

•scripts/core/ - API client, rule engine, unified rules
•scripts/operations/ - Categorization, batch processing, transaction updates
•scripts/analysis/ - Spending analysis, trend detection
•scripts/reporting/ - Multi-format report generation
•scripts/tax/ - ATO mappings, deductions, CGT, BAS preparation
•scripts/scenarios/ - Historical, projections, optimization, tax scenarios
•scripts/status/ - Status dashboard for SessionStart hook
•scripts/scheduled/ - Automated scheduled tasks (cron/launchd)
•scripts/health/ - Health check engine, recommendations, monitoring
•scripts/workflows/ - Interactive categorization workflows
•scripts/utils/ - Backup, validation, logging, merchant normalization

Unified Rule System

Agent Smith uses a YAML-based unified rule system for transaction categorization and labeling.

Quick Start with Rules

bash

# 1. Choose a template for your household type
uv run python scripts/setup/template_selector.py

# 2. Customize rules in data/rules.yaml

# 3. Test with dry run
uv run python scripts/operations/batch_categorize.py --mode=dry_run --period=2025-11

# 4. Apply to transactions
uv run python scripts/operations/batch_categorize.py --mode=apply --period=2025-11

Example Rule

yaml

rules:
  # Category rule - categorize transactions
  - type: category
    name: WOOLWORTHS → Groceries
    patterns: [WOOLWORTHS, COLES, ALDI]
    category: Food & Dining > Groceries
    confidence: 95

  # Label rule - apply labels based on context
  - type: label
    name: Shared Groceries
    when:
      categories: [Groceries]
      accounts: [Shared Bills]
    labels: [Shared Expense, Essential]

Key Features

•Two-phase execution: Categories first, then labels
•Pattern matching: Regex patterns with exclusions
•Confidence scoring: 0-100% for auto-apply logic
•LLM fallback: AI categorization when rules don't match
•Intelligence modes: Conservative/Smart/Aggressive
•Template system: Pre-built rules for common household types
•Operational modes: DRY_RUN/VALIDATE/APPLY for safe testing

See references/unified-rules-guide.md for complete documentation.

Deduction Detection Example

python

from scripts.tax.deduction_detector import DeductionDetector

detector = DeductionDetector()
result = detector.detect_deduction(transaction)
# Returns: {"is_deductible": True, "confidence": "high",
#           "reason": "Office supplies", "substantiation_required": True}

CGT Tracking Example

python

from scripts.tax.cgt_tracker import CGTTracker, AssetType
from decimal import Decimal
from datetime import date

tracker = CGTTracker()
tracker.track_purchase(
    asset_type=AssetType.SHARES,
    name="BHP Group",
    quantity=Decimal("100"),
    purchase_date=date(2023, 1, 1),
    purchase_price=Decimal("45.50"),
    fees=Decimal("19.95")
)

event = tracker.track_sale(
    asset_type=AssetType.SHARES,
    name="BHP Group",
    quantity=Decimal("100"),
    sale_date=date(2024, 6, 1),
    sale_price=Decimal("52.00"),
    fees=Decimal("19.95")
)
# Returns CGTEvent with capital_gain, discount_eligible, holding_period_days

Scenario Analysis

Historical Analysis

python

from scripts.scenarios.historical import calculate_what_if_spending

scenario = calculate_what_if_spending(
    transactions=transactions,
    category_name="Dining",
    adjustment_percent=-30.0,  # 30% reduction
    start_date="2025-01-01",
    end_date="2025-12-31"
)
print(f"Savings: ${scenario['savings']:.2f}")

Spending Forecast

python

from scripts.scenarios.projections import forecast_spending

forecast = forecast_spending(
    transactions=transactions,
    category_name="Groceries",
    months_forward=6,
    inflation_rate=3.0
)

Optimization Suggestions

python

from scripts.scenarios.optimization import suggest_optimizations

optimizations = suggest_optimizations(transactions=transactions)
print(f"Potential savings: ${optimizations['potential_annual_savings']:.2f}")

Command Architecture Patterns

All Agent Smith commands follow consistent patterns for reliability and maintainability.

1. Deterministic Python Scripts

Commands delegate to git-tracked Python scripts in scripts/ for all operations:

code

User Request → Slash Command → Python Script → PocketSmith API
     (UX)        (Guidance)      (Logic)         (Data)

Why this matters:

•Same inputs always produce same outputs
•All logic is testable and auditable
•No hidden state or side effects

2. Subagent Delegation Pattern

Commands use subagents to preserve main conversation context:

markdown

**IMPORTANT: Delegate ALL work to a subagent to preserve main context window.**

Use the Task tool with `subagent_type: "general-purpose"` to execute...

When to use subagents:

•Batch operations (>50 transactions)
•Multi-step workflows with verbose output
•Operations that could pollute context

3. Guided Workflow Pattern

Every command follows this structure:

•Goal - What will this accomplish?
•Why This Matters - Business context
•Execution Steps - Numbered steps with scripts
•Next Steps - What to do after completion

4. Visual Style Guidelines

Element	Usage
Emojis	Status: ✅ success, ⏳ processing, ⚠️ warning, ❌ error
Progress	`[23/100] Processing...`
Tables	Results summaries
ASCII bars	Health dimensions: `████████░░ 80%`

5. Subagent Orchestration

Agent Smith uses intelligent subagent orchestration for complex operations:

When to delegate to subagents:

•Transaction count > 100
•Estimated tokens > 5000
•Bulk processing or deep analysis
•Multi-period operations
•Parallelization opportunities

Subagent types:

•general-purpose - Most operations (categorization, analysis, reporting)
•Purpose-built agents for specialized workflows

Context preservation: Main skill maintains user preferences, session state, and high-level decisions while subagents handle heavy processing.

Health Check System

bash

# Run comprehensive health check
uv run python scripts/health/check.py --full

6 Health Dimensions (scored 0-100):

•Data Quality (25%) - Uncategorized rate, duplicates, gaps
•Category Structure (20%) - Depth, unused categories, distribution
•Rule Engine (15%) - Coverage, efficiency, conflicts
•Tax Readiness (15%) - Tax categorization, compliance
•Automation (10%) - Savings automation, bill scheduling
•Budget Alignment (15%) - Variance, overspending

Output includes:

•Overall score with status (Poor/Fair/Good/Excellent)
•Individual dimension scores
•Top 3 prioritized recommendations
•Projected score after improvements

Automated monitoring:

•Weekly quick health checks
•Monthly full health analysis
•Pre-EOFY comprehensive check
•Post-major-operation validation

Critical Operating Rules

NEVER create custom one-off scripts for core Agent Smith operations.

Agent Smith has a complete architecture with:

•Slash commands (/smith:categorize, /smith:analyze, etc.)
•Python workflows in scripts/workflows/
•Core operations in scripts/operations/
•Proper API client with correct endpoints in scripts/core/api_client.py

If you find yourself writing a new Python script to:

•Categorize transactions
•Analyze spending
•Generate reports
•Update PocketSmith data
•Run health checks

STOP. You are reinventing the wheel.

Instead:

•Check if a slash command exists (/smith:*)
•Check if a workflow exists in scripts/workflows/
•Check if a core operation exists in scripts/operations/
•Use the existing code that has been tested and uses correct API endpoints

Why this matters:

•Custom scripts may use wrong API endpoints (e.g., /users/{id}/transactions/{id} instead of /transactions/{id})
•Custom scripts bypass rule engine, validation, backup, and audit systems
•Custom scripts duplicate functionality that already exists
•Custom scripts won't benefit from future improvements

Exception: Only create new scripts when building NEW features not yet in the design, and always place them in the correct scripts/ subdirectory.

Best Practices

Transaction Categorization

•Always use /smith:categorize - Never create custom categorization scripts
•Start with a rule template matching your household type
•Use dry-run mode to preview categorization
•Review and adjust rules based on results
•Monitor rule performance metrics
•Let AI handle edge cases (LLM fallback)

Tax Compliance

•Configure appropriate tax level for your needs
•Track all deductible expenses as they occur
•Maintain receipt documentation (>$300 ATO requirement)
•Review tax reports before EOFY (June 30)
•Consult registered tax agent for complex situations

Financial Health

•Run health checks monthly
•Address high-priority recommendations first
•Maintain 95%+ categorization rate
•Review and clean up unused categories
•Set up automated alerts for budget overruns

Backup and Safety

•Always backup before bulk operations (automatic)
•Use dry-run mode for untested operations
•Review audit trail for unexpected changes
•Maintain 30 days of recent backups
•Export tax reports for 7-year ATO retention
