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 | $0.00077 | $0.02734 |
| Opus 5.5 | $0.00031 | $0.01094 |
| Sonnet 5.5 | $0.00015 | $0.00547 |
| Haiku 4.5 | $0.00008 | $0.00273 |
Grade A, and why
finance-ops 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 1mo 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 — 142 lines — stays where its author put it; the contents beside it link to each section on GitHub.
finance-ops
You are the controller for a small company run on a cash basis. Your job is not to post the ledger and not to send invoices — it is to answer four questions and leave proof: is the company solvent, are the books trustworthy, did we close the month, and where will the cash run out.
Every engagement leaves behind at least one checkable artifact — which one depends on the job you pick below. scripts/verify.sh checks the shape and internal consistency of those artifacts (columns present, ending balance rolls forward, no unclassified bank lines, no silently-missing close gates). It does not judge whether the dollar figures are right — that is your job.
Pick the job first
The flow genuinely branches. Decide which of the four you are doing before touching a sheet.
| If the ask is… | You are doing | Artifact you produce | Reference |
|---|---|---|---|
| "will we run out of cash", "what's our runway", "13-week forecast", "burn rate" | Forecast | 13-week rolling forecast CSV/sheet — the runway answer | references/cash-flow-forecast.md |
| "reconcile the bank", "these don't match", "what cleared" | Reconcile | report partitioning every bank line into matched / unmatched / needs-review | references/reconciliation.md |
| "set up categories", "everything's in Other", "how do I categorize this" | Categorize | tax-return-aligned category map | (inline below) |
| "close the books for May", "what's left before we close" | Close | 5-day checklist, every gate done or blocked | references/month-close.md |
If the ask is actually about posting entries, sending invoices, or a multi-year model, stop and route — see Hand-offs at the bottom. Do not silently do another skill's job.
Cash-flow forecast
The standard short-horizon tool is the 13-week rolling direct-method forecast. Use it; do not invent a horizon.
- 13 weeks = one quarter. Short enough that every line maps to a named invoice or bill, not a statistical guess. Why: a week-by-week liquidity view is only trustworthy if each cell traces to real money you can point at.
- Rolling, not static. Each week you drop the oldest week and add a new week 13. Why: a static forecast rots the day it's built; rolling keeps the runway answer current.
- Direct method only. List actual cash receipts and disbursements by counterparty/category. Why: you can see exactly which payment to delay or which collection to chase. The indirect method (start from net income, adjust) is for statements, not weekly liquidity — never use it here.
- Enter inflows when cash clears the bank, not when the invoice is sent. This single discipline is what makes the forecast trustworthy.
- Bad: book a $12k invoice in the week you emailed it.
- Good: read the AR aging, map the $12k to the week that customer's payment pattern says it clears (e.g. net-30 customer who always pays week 5).
- AR collections are typically 60–85% of inflows. Map them from the AR aging report (which
invoicingproduces) to expected-collection weeks by each customer's payment behaviour. ending_cashof week n is thestarting_cashof week n+1. This rolling continuity is mandatory andverify.shenforces it. A forecast where the balance doesn't carry forward is wrong, full stop.
What ships with it
6 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.
- 1mo ago First seen · 142 lines · 77 tokens per session scan A 2abee043b29a
finance-ops is a skill published in the GitHub repository ericrisco/rsc-harness (247 stars, last pushed yesterday), licensed MIT. It adds 77 tokens to every session and 2,734 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 2026-09-03.
Other skills, from other repositories
financial-analysis
Financial figures done carefully: periods and fiscal calendars, units and currencies, reconciliation, magnitude sanity checks, sourced assumptions. Use for statements, budgets, pricing, and diligence numbers.
huawei-billing
Use when querying bills, costs, resource usage, or billing details on Huawei Cloud (BSS). Triggers: billing, BSS, cost, bill, expense, usage report, resource usage, budget. NOT for: resource management (use huawei-ecs etc.), creating resources.
sipcode-spend
Report how much the user spent on Codex (tokens and cost at API prices) today, this month, the projected month end, or over a period, from their local Codex logs, using the Sipcode CLI. Use when the user asks how much they spent on Codex, how many tokens Codex used today or this month, or what this month will cost.
aomi-transact-v2
Use this skill to operate the Aomi CLI for natural-language crypto and DeFi workflows, including balance checks, route simulation, transaction review, and explicit user-approved signing flows across EVM chains.
merge-aliases
Folds two surface names for the same backend system into one canonical entity, keeping every original mention individually retrievable, and refuses to merge pairs that only share spelling.
anchor-and-lock
Consults a check that sits outside the loop system before finalizing any decision the frozen facts bear on, and refuses every attempt by a loop to rewrite a node marked frozen, regardless of how convergent the loop's own reasoning looks.
