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 | $0.00032 | $0.05623 |
| Opus 5.5 | $0.00013 | $0.02249 |
| Sonnet 5.5 | $0.00006 | $0.01125 |
| Haiku 4.5 | $0.00003 | $0.00562 |
Grade A, and why
procure-to-pay-advisor 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.

Procure-to-Pay Advisor — Reference Skill
Purpose
Provide the complete multi-jurisdiction framework for procure-to-pay (P2P) accounting advisory — from purchase order matching through AP accruals, vendor management, VAT/GST input credit recovery, and procurement fraud controls.
Part 1: PO Matching — 2-Way, 3-Way, and 4-Way
Matching Types
| Match Type | Documents Compared | What Is Verified |
|---|---|---|
| 2-way match | PO vs. supplier invoice | Price, quantity, terms |
| 3-way match | PO vs. goods receipt (GRN) vs. supplier invoice | Price, quantity, and physical receipt confirmed |
| 4-way match | PO vs. GRN vs. inspection record vs. supplier invoice | Price, quantity, receipt, and quality/inspection sign-off |
Best practice: 3-way matching is the minimum standard for goods purchases. 4-way matching is appropriate for regulated industries (pharmaceuticals, aerospace, food safety) or high-value capital equipment where inspection sign-off is contractually required.
Purchase Price Variance (PPV)
PPV arises when the actual invoiced price differs from the standard or PO price:
PPV = (Actual Price − Standard/PO Price) × Quantity Received
- Favorable PPV: actual price < PO price → credit to PPV account.
- Unfavorable PPV: actual price > PO price → debit to PPV account.
Accounting treatment by jurisdiction:
| Jurisdiction | Standard | PPV Treatment |
|---|---|---|
| US GAAP | ASC 330-10 (Inventory) | Capitalize into inventory cost or expense if immaterial; significant variances may require allocation to COGS and ending inventory |
| IFRS | IAS 2.10 | Included in cost of inventory; abnormal purchase cost variances expensed immediately (IAS 2.16) |
| German HGB | §255 HGB (Herstellungskosten) | Cost of purchase (Anschaffungskosten) — invoiced price + ancillary costs; price variances absorbed into inventory at actual cost |
| JGAAP | ASBJ Statement No. 9 | Actual cost or standard cost (with variance adjustment to COGS) |
What ships with it
2 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.
