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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00124 | $0.01897 |
| Opus 5 | $0.00062 | $0.00949 |
| Sonnet 5 | $0.00025 | $0.00379 |
| Haiku 4.5 | $0.00012 | $0.00190 |
Grade A, and why
expense-wrangler 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.
How it starts
The opening of the file, as written. The whole thing — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to use this skill
Use it when the user wants receipts pulled out of email and logged, the way a bookkeeper would do it:
- "Log my expenses" / "sort my expenses" / "pull my receipts"
- "Find my receipts from this month" / "last quarter" / "since April"
- "Build my expense report" / "get these into my tracker"
- Any request to turn email receipts and invoices into a categorised, totalled list.
Do not use it to pay an invoice, to file a tax return, or to write rows without showing the user the table first and getting a yes. It reads email and proposes rows. The user approves the write.
What it needs (setup)
One read connector and one write target:
- Gmail connector (read, search). Finds the receipts and reads the message body. It cannot send, and it cannot reliably open PDF or image attachments (see the limitation below).
- A write target, one of:
- Airtable connector (recommended). Writes each expense as a real record in a base and table you name. This is the only option that appends live rows on its own.
- Google Sheets. There is no native row-writer connector for Sheets today. Claude produces a paste-ready block (tab-separated) you drop straight into the sheet, or writes a CSV to Drive. It cannot silently append to a live Sheet, and it will not pretend to.
- The accounting system of record: Xero. Where the user's books live in Xero, the logged rows are the hand-off into it. The Xero connector here is read-only, so the skill prepares clean, categorised rows for the user to import or enter into Xero. It never posts into the books on its own.
If the write target is not connected, say which one to enable and stop. Do not invent a tracker or hold rows "in memory" as if they were saved.
The limitation this skill is built around: a receipt's amount, tax, and date often live inside a PDF or image attachment, and the Gmail connector cannot open those reliably. When a figure is only in an attachment Claude cannot read, it does not guess from the subject line or a rounded number. It logs what it can read and marks the rest [NEEDS: open attachment] for the user to fill. Better a parked row than a wrong one.
What ships with it
1 file 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.

expense-wrangler is a skill published in the GitHub repository charlie947/life-automation-skills (23 stars, last pushed 14d ago), licensed MIT. It adds 124 tokens to every session and 1,897 once invoked, about $0.0006 per session on Opus 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 2026-08-30.
