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 | $0.00211 | $0.02553 |
| Opus 5 | $0.00105 | $0.01277 |
| Sonnet 5 | $0.00042 | $0.00511 |
| Haiku 4.5 | $0.00021 | $0.00255 |
Grade A, and why
s4hana-create-invoice scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
3. **If neither**: auto-create `./.env` from the bundled template (curl from `https://raw.githubusercontent.com/ilia-inovaflow/s4hana-create-record-skills/main/.env.example`), append `.env` to `.gitignore` if not already How it starts

s4hana-create-invoice
Create AP supplier invoices on SAP S/4HANA. Verified production-ready against SAP S/4HANA Cloud Public Edition — 52 invoices posted 2026-05-11 with zero failures.
Phase 0 — Setup check (MANDATORY, no exceptions)
Before any API call, before any tool use, do this check. Even if you already know credentials from earlier in the conversation — IGNORE that knowledge and re-check from scratch each invocation.
- Announce: tell the user "Checking for SAP credentials in
<current cwd>..." - Check ONLY these two sources:
- A
.envfile at./.env(in the current working directory — NOT parent dirs, NOT~/.env, NOT any memory file) - Shell-exported env vars:
SAP_HOSTANDSAP_AUTH_MODEboth present
- A
- If neither: auto-create
./.envfrom the bundled template (curl fromhttps://raw.githubusercontent.com/ilia-inovaflow/s4hana-create-record-skills/main/.env.example), append.envto.gitignoreif not already there, tell the user clearly what to fill in (auth mode + host + creds), and wait for them to say "ready" before making any API call. Never overwrite an existing.env. - If credentials are present: report back to the user: "✓ Loaded credentials for
<host>in<auth-mode>mode. Proceeding with [task]."
Never use credentials from conversation memory, from another project's .env, or from any tenant the user previously worked with in a different session. Each project gets its own .env. See shared/setup-check.md for the full rationale and edge cases.
When to trigger
Verbs: create / post / add / generate / seed / make / backdate / invoice Objects: invoice(s), supplier invoice(s), vendor invoice(s), AP invoice(s) Counts: 1 to ~200 records.
Hard rules (never violate)
- Always do a 1-record live POST as a probe before bulk (≥3 records).
- Never invent master-data IDs — fetch Material/Plant/Currency/Supplier from the source PO line via OData GET.
- If a required field has no sensible default and the user didn't specify → ask once, then auto-pick.
- Scripts go in
<cwd>/.s4hana-tmp/create-invoices-<YYYYMMDD-HHMM>/. Never commit, never modify.env. - POSTs are sequential with 200ms delay; halt on 3 consecutive failures.
- SOAP A2X is the canonical create path on Cloud Public — the OData V2
A_SupplierInvoicePOST works after ledger config is fixed but has stricter line-item field shape (M8/375requiresReferenceDocument/-FiscalYear/-Item). Use SOAP A2X.
What ships with it
5 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.

s4hana-create-invoice is a skill published in the GitHub repository ilia-inovaflow/s4hana-create-record-skills (2 stars, last pushed 2mo ago), licensed MIT. It adds 211 tokens to every session and 2,553 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
