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 | $0.00027 | $0.01028 |
| Opus 5 | $0.00014 | $0.00514 |
| Sonnet 5 | $0.00005 | $0.00206 |
| Haiku 4.5 | $0.00003 | $0.00103 |
Grade A, and why
finance-checkup 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.
This is a copy
80% identical to decision-journal — 26 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mandatory integrity contract
Before acting, load and follow ../../references/data-integrity.md. Its provenance, missing-value, correction-history, defensive-write, backup, and recovery rules are mandatory for this subskill.
Review personal finance coordination signals without becoming a bank, tax system, or password vault. The goal is to surface anomalies, recurring costs, renewal pressure, and useful next actions.
Trigger
Use when the user asks to:
- review spending signals, subscriptions, recurring bills, savings goals, or renewals
- check for unusual charges or upcoming payments
- prepare a money decision or budget review
- track financial documents and deadlines
- decide whether a finance item belongs in tasks, calendar, docs, or an external finance tool
Operating model
- Resolve the active runtime and private data directory.
- Read
$LIFEOS_DATA_DIR/config.jsonwhen available. - If source ownership for this domain is unknown, inspect runtime-owned systems read-only and propose a source decision before writing anything.
- Load only
runtimes/<active-runtime>.mdif runtime-specific commands, storage pointers, delivery, scheduling, or integration behavior are needed. - Do not load other runtime adapters for the same task.
- Prefer pointers, access notes, review dates, and short operational state over duplicated raw data.
- Ask before changing external systems, creating reminders, contacting people, importing data, broad migrations, or destructive cleanup.
- Record useful Life OS coordination state under
$LIFEOS_DATA_DIR/finance-checkup/data.jsonwhen the user/runtime policy allows it.
Source decision
Store the source choice in $LIFEOS_DATA_DIR/finance-checkup/data.json when useful:
{
"source_decisions": {
"finance_records": {
"owner": "runtime|external|life-os",
"runtime": "<active-runtime>",
"source": "<tool-or-system>",
"access": "<short pointer or retrieval instruction>"
}
}
}
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
