Why use it?
It brings together budget status, planned expenses, and funding gaps so problems can be spotted quickly.

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

budget 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.

What it actually says

Run a quick budget health check:

  1. Call sync_data() to refresh from YNAB
  2. Call budget_check() to get RTA, overspent categories, near-limit, underfunded goals, and health ratios
  3. Call planned_expenses() to surface any upcoming planned expenses with funding gaps

Present results as a concise summary: highlight anything that needs attention (overspent categories, underfunded goals, upcoming expenses with gaps) and note what looks healthy. Keep it brief - the user wants a quick pulse check, not a deep analysis.

Changes

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.
