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

ynab-windfall-planner 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 9d 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.

YNAB Windfall Planner

What this does

Provides a decision framework for a one-time lump sum so it gets actively allocated instead of dissolving into a checking balance and quietly getting spent. Walks through a prioritization order and flags "getting a month ahead" as a particularly high-leverage use for anyone currently paycheck-to-paycheck.

When to use this skill

  • "I just got a bonus, what should I do with it?"
  • "I'm getting a tax refund"
  • "I inherited some money"
  • "I have extra cash, what's the smart move?"

Should NOT trigger on: executing the chosen allocation once decided (use ynab-assign-money) — this skill is the decision framework, not the execution step. It also doesn't replace the depth of ynab-debt-payoff-planner or ynab-emergency-fund-builder — it decides the split across them.

Workflow

Step 1 (if MCP-connected): Check current state

Call MCP tool: ynab_quick_summary Call MCP tool: ynab_category_balances Call MCP tool: ynab_goal_progress

Step 2: Walk the prioritization order

Present this order, explaining that windfalls are a decision point, not something to let dissolve into a balance:

  1. High-interest debt — if a credit card or similar is carrying a balance, this is usually the highest-return use of the money.
  2. Emergency fund — if the buffer is thin or nonexistent, top it up next (see ynab-emergency-fund-builder for staged targets).
  3. Behind true-expense categories — catch up anything that's fallen short (see ynab-true-expenses).
  4. Existing savings goals — accelerate a goal already in motion (house, car — see ynab-big-goal-savings-planner).
  5. Discretionary — it's fine, and recommended, to spend some of it on something enjoyable; the point is an active decision, not zero fun.

Step 3: Flag "getting a month ahead" as an accelerant

If the person describes living paycheck-to-paycheck, note that a windfall is a common and effective way to jump-start funding next month's expenses ahead of time — one of YNAB's highest-leverage milestones.

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.
