What is caisse-du-jour?

A point-of-sale cash-register workflow covering opening, payments, reports, and end-of-day Z closing. A POS is the system used to record restaurant sales and payments.

Use it to open a cash session, take payments by cash or card and other supported methods, calculate change, view the register report, and close the session.

It adds checks and confirmations around real-money actions, reducing mistakes with operators, payment amounts, change, and closing totals.

Token cost

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	$0.00000	$0.00911
Opus 5	$0.00000	$0.00456
Sonnet 5	$0.00000	$0.00182

Security

Grade A, and why

caisse-du-jour 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 9d 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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Caisse du jour (POS FoodEatUp)

Cycle ouverture → encaissements → rapport → clôture Z. Argent réel : chaque encaissement et la clôture sont confirmés. Rien d'inventé (montants, modes, rendu viennent du serveur).

Étape 0 — Références et établissement (obligatoire)

Charger ${CLAUDE_PLUGIN_ROOT}/reference/directives-outils.md et l'appliquer.
S'assurer d'avoir l'establishment_id (le demander si absent).
Un encaissement/une clôture exige un opérateur (operator_id = employé avec la permission caisse) — le résoudre via list_employees si besoin, jamais deviné.

1. Ouvrir la caisse

open_pos_session : opening_float (fond de caisse), operator_id. Vérifier qu'aucune session n'est déjà ouverte (get_pos_session) avant d'ouvrir.

2. Encaisser une note

record_pos_payment : order_id, amount, method ∈ especes/carte/titre_restaurant/cheque, operator_id ; tendered (espèces, pour le rendu). Argent réel → confirmation avant l'appel.

titre_restaurant : jamais de rendu (ne pas renseigner un rendu).
La note est soldée quand le reste dû = 0 — vérifier avec list_pos_payments (paiements, montants, rendu, reste dû) plutôt que de supposer.

3. Rapport de caisse (X / Z)

get_pos_report : sans session_id = rapport X (session en cours) ; avec session_id = rapport Z (session clôturée). CA, ticket moyen, par mode, par opérateur, TVA, remises — restitués tels quels.

4. Clôturer (Z)

get_pos_session pour l'état, puis clôture Z : close_pos_session (operator_id, confirm ; counted_cash optionnel pour le comptage des espèces, écart calculé par le serveur). Le serveur exige confirm:true → le skill résume le rapport X à l'opérateur (CA, écart annoncé) puis confirme, jamais confirm:true d'office. Après clôture, présenter le Z (get_pos_report avec le session_id).

Ardoises clients ouvertes (soldes dus) : list_pos_tabs — le règlement se fait en caisse (record_pos_payment).

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.
