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 | $0.00096 | $0.06441 |
| Opus 5.5 | $0.00038 | $0.02576 |
| Sonnet 5.5 | $0.00019 | $0.01288 |
| Haiku 4.5 | $0.00010 | $0.00644 |
Grade A, and why
accounting-finance 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 2mo 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 — 313 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Accounting & Finance
Not tax, legal, or audit advice. This skill encodes general operator practice and standard frameworks (US GAAP, IFRS, ASC 606/IFRS 15, EU VAT). Rates, thresholds, registration triggers, and filing rules change and are jurisdiction-specific. Before filing anything or relying on a number for a board, lender, investor, or tax authority, have it reviewed by a qualified accountant/tax advisor licensed in the relevant jurisdiction. Route any edge case — multi-state US nexus, cross-border digital services, equity/SAFE accounting, R&D capitalization, transfer pricing, M&A, or revenue-recognition judgment calls — to a professional. Treat every concrete rate/threshold below as "verify before use."

1. P&L Structure (GAAP / IFRS)
Standard multi-step income statement. Key rule: define what OpEx contains so D&A is counted exactly once. Below, operating expenses are stated excluding depreciation & amortization (the "ex-D&A" convention common in SaaS reporting); D&A is its own line. EBITDA then equals operating income + D&A with no double-count. If your accounting system buckets D&A inside OpEx, drop the separate D&A line and compute EBITDA = operating income + D&A (added back), not by re-subtracting it.
| # | Line item | Calculation | Watch for |
|---|---|---|---|
| 1 | Revenue (net) | Recognized per ASC 606/IFRS 15 (§6), net of refunds/credits | Recognized ≠ billed ≠ cash collected. Don't book deferred revenue as revenue. |
| 2 | COGS / Cost of revenue | Hosting/infra, third-party API/usage fees, payment processing, customer support & success delivery, onboarding/implementation labor | SaaS COGS typically 15–30% of revenue. Keep R&D and S&M out of COGS. |
| 3 | Gross profit | Revenue − COGS | SaaS target gross margin 70–85%. |
| 4 | Operating expenses (ex-D&A) | Sales & Marketing + Research & Development + General & Administrative | Allocate fully-loaded headcount (salary + employer taxes + benefits) to the right function. |
| 5 | EBITDA | Gross profit − OpEx(ex-D&A) | Proxy for operating cash generation; ignores capex, financing, tax. |
| 6 | Depreciation & amortization | Capitalized assets + capitalized software/intangibles amortization | Pure non-cash; never in COGS and here. |
| 7 | Operating income (EBIT) | EBITDA − D&A | GAAP operating result. |
| 8 | Net interest | Interest expense − interest income | |
| 9 | Pre-tax income (EBT) | EBIT − net interest ± other | |
| 10 | Income tax expense | Current + deferred tax | Tax expense (accrual) ≠ tax paid (cash). |
| 11 | Net income | EBT − income tax | Bottom line. |
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.
