Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00079 | $0.00791 |
| Opus 5.5 | $0.00032 | $0.00316 |
| Sonnet 5.5 | $0.00016 | $0.00158 |
| Haiku 4.5 | $0.00008 | $0.00079 |
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 2mo 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:
- Starter fund: ~$500 — enough to absorb a small surprise without going into debt.
- Intermediate: $1,000-2,000 — covers most common one-off emergencies.
- 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.
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.

ynab-emergency-fund-builder is a skill published in the GitHub repository auzroz/ynab-mcp (5 stars, last pushed today), licensed MIT. It adds 79 tokens to every session and 791 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
