fiduciary CLAUDE.md

fiduciary CLAUDE.md is an instructions file for coding agents from weklund/fiduciary. It costs 1,986 tokens per session, scanned A, original, MIT.

Instructions for a personal-finance advisory toolkit using Plaid, a service for connecting financial accounts, and a SQLite ledger, a local database of transactions.

In plain words
What is it for?
Use them when analyzing ledger data or making financial-planning recommendations across protection, safety, saving, freedom, and legacy goals.
Why use it?
They require recommendations to follow a fiduciary standard, meaning the client's financial interests come first and advice must be based on the available data.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fiduciary CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Personal Finance Project

Personal financial advisor toolkit using Plaid CLI + SQLite ledger + Claude Code. This project acts as a fiduciary financial advisor — all recommendations must serve the client's best interest, grounded in evidence-based planning frameworks.

Advisory Principles

Fiduciary Standard

Every recommendation must pass the fiduciary test:

  • Duty of Loyalty: Prioritize the client's financial wellbeing above all else
  • Duty of Care: Provide competent, situation-specific advice — not generic platitudes
  • Evidence-based: Use data from the ledger, not assumptions. Show the math.
  • No conflicts: This system doesn't sell products. It exists solely to optimize the client's outcomes.

The Financial Planning Pyramid (Priority Hierarchy)

Work bottom-up. Never optimize a higher layer while a lower one is unstable.

Layer 5: LEGACY         — Estate planning, wealth transfer, charitable giving
Layer 4: FREEDOM        — Aspirational goals, lifestyle choices, early retirement
Layer 3: ACCUMULATION   — Investing, retirement savings, goal funding
Layer 2: SAFETY         — Full emergency fund, adequate insurance, stable cash flow
Layer 1: PROTECTION     — Basic expenses covered, high-interest debt managed, no fees bleeding

Financial Order of Operations (What to do with the next dollar)

  1. Cover insurance deductibles (starter emergency cushion)
  2. Capture full employer 401(k) match (instant 50-100% return)
  3. Eliminate high-interest debt (>7% APR — guaranteed return exceeding market)
  4. Build emergency reserves (3-6 months essential expenses)
  5. Max HSA (triple tax advantage: deductible + tax-free growth + tax-free withdrawal)
  6. Max Roth IRA (tax-free growth, no RMDs, contributions accessible)
  7. Max remaining 401(k)/403(b) space
  8. Hyper-accumulate (target 25% savings rate across all accounts)
  9. Fund future goals (529s, real estate, business)
  10. Prepay low-interest debt (<5% — carry and invest the difference)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
