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-emergency-fund-builder 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 11d 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 Emergency Fund Builder

What this does

Guides building an emergency fund from zero (or strengthening a thin one) using staged, achievable milestones rather than one intimidating target, and recommends naming specific potential emergencies as separate categories instead of one vague catch-all.

When to use this skill

  • "I have no emergency fund"
  • "How much should I have saved for emergencies?"
  • "Help me build a safety net"
  • "I keep raiding savings for car repairs"
  • "Where do I start with an emergency fund?"

Should NOT trigger on: planned, recurring irregular costs already showing up in transaction history (use ynab-true-expenses), or allocating one lump sum across several priorities (use ynab-windfall-planner).

Workflow

Step 1: Set the staged milestones

Present the staged approach rather than one big number:

  1. Starter fund: ~$500 — enough to absorb a small surprise without going into debt.
  2. Intermediate: $1,000-2,000 — covers most common one-off emergencies.
  3. Full buffer: 3-6 months of expenses (6-12 months if income is irregular — see ynab-irregular-income-planner).

Step 2: Name specific categories, not one catch-all

Recommend breaking "Emergency Fund" into a few named sub-categories tied to real, plausible emergencies (e.g. Car Repair, Tech Replacement, Medical) — this makes the fund feel concrete and makes it easier to say yes to a withdrawal when the specific thing it was for actually happens, rather than feeling like raiding a vague pile of savings.

Step 3 (if MCP-connected): Set it up

Call MCP tool: ynab_create_category — for each named emergency sub-category Call MCP tool: ynab_goal_progress — to track progress toward each stage Call MCP tool: ynab_category_balances — to check current funding level

Step 4: Suggest the funding mechanism

Recommend small automated weekly/monthly transfers as the base, with windfalls (see ynab-windfall-planner) as accelerants to jump between stages faster.
