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 | $0.00087 | $0.00714 |
| Opus 5 | $0.00044 | $0.00357 |
| Sonnet 5 | $0.00017 | $0.00143 |
| Haiku 4.5 | $0.00009 | $0.00071 |
Grade A, and why
ynab-assign-money 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 12d 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 Assign Money
What this does
Implements YNAB's first rule — Give Every Dollar a Job — by helping decide where unassigned Ready to Assign money should go this month: underfunded goals first, then unfunded or negative categories, then general allocation guided by spending history.
When to use this skill
- "I have money to assign"
- "Help me budget this month"
- "What should I fund?"
- "Help me set up a new category"
- "Organize my budget categories"
- "Assign my leftover funds"
Should NOT trigger on: fixing an already-overspent category (use
ynab-overspending-triage), or structuring a brand-new budget from scratch
(that's a bigger first-time-setup conversation — see the ynab-first-budget-setup
skill if the MCP isn't yet connected or the budget has no history).
Workflow
Step 1: Check Ready to Assign
Call MCP tool: ynab_quick_summary
Parameters: none
Step 2: Find unfunded categories
Call MCP tool: ynab_category_balances
Parameters: filter: "unfunded"
Step 3: Find underfunded goals
Call MCP tool: ynab_goal_progress
Parameters: filter: "underfunded"
Step 4: Get funding suggestions from history
Call MCP tool: ynab_budget_suggestions
Parameters: none
Step 5 (if needed): Create or update categories
Call MCP tool: ynab_create_category_group / ynab_create_category / ynab_update_category
Parameters: as needed — propose first, confirm, then apply
Output format
Ready to Assign: $X to give a job
Priority funding order:
1. [underfunded goal categories, amount needed]
2. [unfunded/negative categories]
3. [suggested amounts from history]
Proposed allocation: [category: $amount, ...] — confirm to apply?
Troubleshooting
MCP connection failed — confirm the ynab-mcp server is connected.
Unauthorized / token expired — walk the user through reconnecting YNAB rather than retrying.
Ready to Assign is negative — do not proceed with allocation; report the
shortfall and suggest ynab-overspending-triage instead.
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.
