Transaction Recipes Skill

You are modeling complex multi-step accounting scenarios in Jaz — transactions that span multiple periods, involve changing amounts, or require several linked entries to complete a single business event.

Jaz-native, not generic. Every recipe in this skill is designed around the Jaz recipe engine (plan_recipe / execute_recipe), Jaz capsule types, Jaz CoA classifications, and Jaz scheduler primitives. It is NOT an interchangeable IFRS reference; it is the operating manual for posting these transactions through the Jaz ledger. If you find yourself hand-constructing journal entries from this skill, you have skipped step 1 — invoke plan_recipe(recipe: ...) first and let the engine emit the entries.

This skill provides Jaz-contextual recipes with full accounting logic. For API field names and payloads, load the jaz-api skill alongside this one. For the operational close workflows that invoke these recipes (month-end close, GST/VAT filing, year-end close), load the jaz-jobs skill.

When to Use This Skill

• Setting up prepaid expenses, deferred revenue, or accrued liabilities
• Modeling loan repayment schedules with amortization tables
• Implementing IFRS 16 lease accounting (right-of-use assets + lease liabilities)
• Recording hire purchase agreements (ownership transfers, depreciate over useful life)
• Recording depreciation using methods Jaz doesn't natively support (declining balance, 150DB)
• Managing fixed deposit placements with interest accrual schedules (IFRS 9)
• Disposing of fixed assets — sale, scrap, or write-off with gain/loss calculation (IAS 16)
• FX revaluation of non-AR/AP monetary items at period-end (IAS 21)
• Calculating expected credit loss provisions on aged receivables (IFRS 9)
• Accruing employee leave and bonus obligations (IAS 19)
• Recognizing provisions at PV with discount unwinding (IAS 37)
• Declaring and paying dividends
• Recording and reconciling intercompany transactions across entities
• Capitalizing costs in WIP and transferring to fixed assets
• Any scenario that groups related transactions in a capsule over multiple periods

Building Blocks

Every recipe uses a combination of these Jaz features. See references/building-blocks.md for details.

Building Block	Role in Recipes
Capsules	Group all related entries into one workflow container
Schedulers	Automate fixed-amount recurring journals (prepaid, deferred, leave)
Manual Journals	Record variable-amount entries (loan interest, IFRS 16 unwinding, FX reval, ECL)
Fixed Assets	Native straight-line depreciation for ROU assets and completed capital projects
Invoices / Bills	Trade documents for intercompany, supplier bills for capital WIP
Tracking Tags	Tag all entries in a scenario for report filtering
Nano Classifiers	Classify line items by department, cost center, or project
Custom Fields	Record reference numbers (policy, loan, lease contract, intercompany ref)

Key Principle: Schedulers vs Manual Journals

Jaz schedulers generate fixed-amount recurring entries. This determines which recipe pattern to use:

• Fixed amounts each period → Use a scheduler inside a capsule (automated)
• Variable amounts each period → Use manual journals inside a capsule (calculated per period)
• One-off or two-entry events → Use manual journals (e.g., dividend declaration + payment)

If a scenario genuinely fits either pattern, record the pick once the entries post: jot(kind: METHOD) naming the pattern chosen and the deciding fact.

Recipe	Pattern	Why
Prepaid Amortization	Scheduler + capsule	Same amount each month
Deferred Revenue	Scheduler + capsule	Same amount each month
Accrued Expenses	Two schedulers + capsule	Accrual + reversal cycle with end dates
Employee Leave Accrual	Scheduler + capsule	Fixed monthly accrual
Bank Loan	Manual journals + capsule	Interest changes as principal reduces
IFRS 16 Lease	Hybrid (native FA + manual journals) + capsule	ROU depreciation is fixed; liability unwinding changes
Declining Balance	Manual journals + capsule	Depreciation changes as book value reduces
FX Revaluation	Manual journals + capsule	Rates change each period
ECL Provision	Manual journals + capsule	Receivables and rates change each quarter
Fixed Deposit	Cash-out + manual journals + cash-in + capsule	Placement, monthly accruals, maturity
Hire Purchase	Manual journals + FA registration + capsule	Like IFRS 16 but depreciate over useful life
Asset Disposal	Manual journal + FA deregistration	One-off compound entry + FA update
Provisions (IAS 37)	Manual journals + cash-out + capsule	Unwinding amount changes each month
Bonus Accrual	Manual journals + capsule	Revenue/profit changes each quarter
Dividends	Manual journals + capsule	One-off: declaration + payment
Intercompany	Invoices/bills + capsule	Mirrored entries in two entities
Capital WIP	Bills/journals + FA registration + capsule	Accumulate then transfer

Recipe Index

Each recipe includes: scenario description, accounts involved, journal entries, capsule structure, worked example with real numbers, enrichment suggestions, verification steps, and common variations.

Tier 1 — Scheduler Recipes (Automated)

1. Prepaid Amortization — Annual insurance, rent, or subscription paid upfront with monthly expense recognition via scheduler. Typical context: month-end close (period-end recognition step inside the month-end close); set up once at data migration when the prior system hands over a prepaid schedule.

2. Deferred Revenue — Upfront customer payment for a service delivered over time, with monthly revenue recognition via scheduler. Typical context: month-end close (revenue recognition step inside the month-end close); also reviewed at year-end inside the year-end close for true-up.

Tier 2 — Manual Journal Recipes (Calculated)

3. Accrued Expenses — Month-end expense accrual and start-of-month reversal using two schedulers with end dates, plus the actual supplier bill. Paired calculator: clio calc accrued-expense. Typical context: month-end close (accruals step inside the month-end close).

4. Bank Loan — Loan disbursement, monthly installments splitting principal and interest, full amortization table with worked example. Typical context: ad-hoc (one-off setup at loan drawdown, then month-end close picks up each installment journal via the scheduler the recipe creates).

5. IFRS 16 Lease — Right-of-use asset recognition, lease liability unwinding with changing interest, native FA for ROU straight-line depreciation. Typical context: month-end close (depreciation + liability unwinding booking each period inside the month-end close) and year-end (ROU register sign-off inside the fixed-asset review + the year-end close).

6. Declining Balance Depreciation — DDB/150DB methods with switch-to-straight-line logic, for assets where Jaz's native SL isn't appropriate. Typical context: month-end close (depreciation booking inside the month-end close) and year-end (asset register review inside the fixed-asset review).

7. Fixed Deposit — Placement, monthly interest accrual (simple or compound), and maturity settlement. IFRS 9 amortized cost. Paired calculator: clio calc fixed-deposit. Typical context: month-end close (interest accrual journal each period inside the month-end close); placement + maturity events handled ad-hoc.

8. Hire Purchase — Like IFRS 16 lease but ownership transfers — ROU depreciation over useful life (not lease term). Paired calculator: clio calc lease --useful-life <months>. Typical context: month-end close (monthly depreciation + interest unwinding inside the month-end close) and year-end (asset register sign-off inside the fixed-asset review).

9. Asset Disposal — Sale at gain, sale at loss, or scrap/write-off. Computes accumulated depreciation to disposal date and gain/loss. Paired calculator: clio calc asset-disposal. Typical context: ad-hoc (triggered by a disposal event) and year-end (asset register review inside the fixed-asset review surfaces unposted disposals).

Tier 3 — Month-End Close Recipes

10. FX Revaluation — verification only — Jaz auto-handles ALL period-end IAS 21.23 FX translation (AR, AP, cash, bank, intercompany, term deposits, FX provisions). The recipe and clio calc fx-reval are for VERIFICATION ONLY (independent cross-check vs what Jaz auto-posted). Do NOT invoke execute_recipe(recipe: 'fx-reval', ...) — would double-post. Typical context: period-end / year-end FX verification flow.

11. Bad Debt Provision / ECL — IFRS 9 simplified approach provision matrix using aged receivables and historical loss rates. Paired calculator: clio calc ecl. Typical context: GST/VAT filing cycle (ECL reviewed alongside the return prep since AR aging is already pulled) and year-end (ECL true-up inside the year-end close).

12. Employee Benefit Accruals — IAS 19 leave accrual (scheduler, fixed monthly) and bonus accrual (manual journals, variable quarterly) with year-end true-up. Paired calculator: clio calc leave-accrual. Typical context: month-end close (leave-accrual scheduler runs inside the month-end close); bonus accrual revisited each quarter and at year-end (true-up inside the year-end close).

Tier 4 — Corporate Events & Structures

13. Provisions with PV Unwinding — IAS 37 provision recognized at PV, with monthly discount unwinding schedule. For warranties, legal claims, decommissioning, restructuring. Paired calculator: clio calc provision. Typical context: month-end close (monthly discount-unwinding journal inside the month-end close); initial recognition triggered ad-hoc when the obligating event occurs.

14. Dividend Declaration & Payment — Board-declared dividend: two journals (declaration reducing retained earnings, then payment). Optional withholding tax adds a third step. Paired calculator: clio calc dividend. Typical context: year-end (dividend declaration is part of the year-end close after profit is finalized) or ad-hoc (interim dividends).

15. Intercompany Transactions — Mirrored invoices/bills or journals across two Jaz entities with matching intercompany reference, quarterly settlement. Typical context: month-end close (mirror entries booked each period inside the month-end close) and year-end (intercompany elimination + confirmation inside audit prep).

16. Capital WIP to Fixed Asset — Cost accumulation in CIP account during construction/development, transfer to FA on completion, auto-depreciation via Jaz FA module. Typical context: month-end close (cost accumulation each period) and year-end (transfer to FA + commissioning review inside the fixed-asset review).

How to Use These Recipes

1. Read the recipe for your scenario — understand the accounts, journal entries, and capsule structure.
2. Create the accounts listed in the "Accounts Involved" table (if they don't already exist in the CoA).
3. Create the capsule with an appropriate capsule type.
4. Run the calculator (if available) to generate exact amounts: clio calc <command> --json gives you a complete blueprint. Where you picked the method yourself (e.g. --method ddb over sl), record the judgment after the entries post: jot(kind: METHOD) naming the method and why.
5. Record the initial transaction (bill, invoice, or journal) — assign it to the capsule.
6. For scheduler recipes: Create the scheduler with the same capsule — it generates all subsequent entries automatically.
7. For manual journal recipes: Record each period's journal using the calculator output or worked example, always assigning to the same capsule.
8. Verify using the steps in each recipe (ledger grouping by capsule, trial balance checks).

Financial Calculators (CLI)

The jaz-clio CLI includes 13 IFRS-compliant financial calculators. Each produces a formatted schedule + per-period journal entries + human-readable workings. Use --json for structured output with a complete blueprint — capsule type/name, tags, custom fields, workings (capsuleDescription), and every step with action type, date, accounts, and amounts.

All calculators support --currency <code> and --json.

Inputs the data does not hand you (loss rates, discount rate, salvage value, useful life) are assumptions: once the entries post, lock each with jot(kind: ASSUMPTION) naming the value and its source.

Each calculator has a typical context — see the line after each command for the operational workflow that typically invokes it.

Blueprint Output (--json)

Every calculator's --json output includes a blueprint object — a complete execution plan for creating the capsule and posting all transactions in Jaz:

{
  "type": "loan",
  "currency": "SGD",
  "blueprint": {
    "capsuleType": "Loan Repayment",
    "capsuleName": "Bank Loan — SGD 100,000 — 6% — 60 months",
    "capsuleDescription": "Loan Amortization Workings\nPrincipal: SGD 100,000.00 | Rate: 6% p.a. ...",
    "tags": ["Bank Loan"],
    "customFields": { "Loan Reference": null },
    "steps": [
      {
        "step": 1,
        "action": "cash-in",
        "description": "Record loan proceeds received from bank",
        "date": "2025-01-01",
        "lines": [
          { "account": "Cash / Bank Account", "debit": 100000, "credit": 0 },
          { "account": "Loan Payable", "debit": 0, "credit": 100000 }
        ]
      }
    ]
  }
}

Blueprint action types — each step tells you HOW to execute it in Jaz:

Action	When used	Jaz module
bill	Supplier document (prepaid expense)	Bills
invoice	Customer document (deferred revenue)	Invoices
cash-in	Cash arrives in bank (loan disbursement, FD maturity)	Bank / Manual Journal
cash-out	Cash leaves bank (FD placement, provision settlement)	Bank / Manual Journal
journal	No cash movement (accrual, depreciation, unwinding, reval)	Manual Journals
fixed-asset	Register/update FA module (ROU asset, capital project)	Fixed Assets
note	Instruction only (deregister FA on disposal)	N/A

Math guarantees:

• financial npm package (TypeScript port of numpy-financial) for PV, PMT — no hand-rolled TVM
• 2dp per period, final period closes balance to exactly $0.00
• Input validation with clear error messages (negative values, invalid dates, salvage > cost)
• DDB→SL switch when straight-line >= declining balance or when DDB would breach salvage floor
• All journal entries balanced (debits = credits in every step)

Agent Tools (Daemon)

When running as a daemon agent (clio serve), recipes are available via two dedicated tools:

• plan_recipe (read-only): Run a calculator and see what accounts, contacts, and bank accounts are needed — no API calls. Use this first to verify requirements.
• execute_recipe (write): Full end-to-end recipe execution — run calculator, auto-resolve accounts from chart of accounts, create capsule, post all entries. 1 tool call replaces ~20 manual tool calls.

Both tools accept all 13 recipe types: loan, lease, depreciation, prepaid-expense, deferred-revenue, fx-reval, ecl, provision, fixed-deposit, asset-disposal, accrued-expense, leave-accrual, dividend.

Scheduler creation tools are also available: create_scheduled_journal, create_scheduled_invoice, create_scheduled_bill.

Server-side recipe execution (Jaz API)

A second path: 5 IFRS recipes (Loan Amortization, Accrual Reversal, Prepaid Amortization, Deferred Revenue, IFRS 16 Lease) also have a SERVER-SIDE lifecycle via Jaz REST. This produces real capsule entities + scheduler atoms (recurring journal postings) — distinct from the offline plan_recipe / execute_recipe path which is client-side compute.

Two distinct execution paths:

Path	When to use	Tools
Offline calculator	Plan first, post manually. Agent has CoA picked. No need for a server-side capsule entity. Works without an API key.	plan_recipe → execute_recipe
Server-side trigger	"Create the bill AND the prepaid amortization schedule in one shot." Capsule entity needed for FE/reporting. Requires API key.	Trigger via capsuleRecipe payload on create_bill / create_invoice / create_journal / create_cash_in / create_cash_out (and their update_* variants), OR standalone preview_capsule_recipe first.

Server-side tools (group: capsule_recipes):

• list_capsule_recipes (read-only) — list registered IFRS recipes + per-version JSON Schemas. SOURCE OF TRUTH for recipeName values; don't hard-code.
• get_capsule_recipe(name) (read-only) — one descriptor by enum name with versions[].inputSchema.
• preview_capsule_recipe({recipeName, recipeVersion?, inputs, baseTransactionResourceId?, baseTransactionType?, organizationResourceId?}) (read-only) — pure compute, no side effects. Returns {legs[], expectedOutput[], previewMarkdown}. Use BEFORE triggering via capsuleRecipe payload to validate inputs.
• resume_capsule_recipe(capsuleResourceId) (write, NOT idempotent) — retry a FAILED recipe job from its failed leg. ≤3 same-leg attempts then terminal BLOCKED_AFTER_3_RESUME_ATTEMPTS.
• rollback_capsule_recipe(capsuleResourceId, dryRun?: boolean) (write; dryRun IS idempotent) — delete every scheduler atom created by the recipe. Preview with dryRun=true before committing.

Trigger-mutation payload — to create a base-trx AND fire a recipe in one shot, pass capsuleRecipe: {recipeName, recipeVersion?, inputs} to the create/update mutation. Mutually exclusive with capsuleResourceId (the "attach to existing capsule" path).

Three pre-flight gates BEFORE sending capsuleRecipe (else the response silently nulls)

The trigger mutation is best-effort post-commit: if the recipe publish fails inside customer-service, the base-trx still commits, the response still returns 201, but capsuleRecipeJob is null and no error reason is surfaced on the response body. Three causes of silent null — gate every one of them before sending:

Gate	Constraint	Pre-flight check
Base trx type	recipeName must match a trigger mutation in the recipe's allowedBaseTransactionTypes. PREPAID_AMORTIZATION→PURCHASE, DEFERRED_REVENUE→SALE, ACCRUAL_REVERSAL→JOURNAL_MANUAL, IFRS16_LEASE→JOURNAL_MANUAL, LOAN_AMORTIZATION→JOURNAL_DIRECT_CASH_IN | JOURNAL_MANUAL	get_capsule_recipe(name).allowedBaseTransactionTypes ↔ trigger mutation
Currency	Recipe currency, every *AccountResourceId account's currencyCode, and base trx currencyCode ALL must match (v1 recipes are single-currency)	get_account(<id>).currencyCode for every input account
Account class	Each *AccountResourceId slot has an x-accountClass constraint in the recipe inputSchema (Asset/Liability/Expense/Revenue)	get_capsule_recipe(name).versions[0].inputSchema.properties.<field>['x-accountClass'] vs get_account(<id>).accountClass

The canonical pre-flight is one call: preview_capsule_recipe(recipeName, inputs). Pure-compute (no side effects). Surfaces every input/class/currency violation as a clean 422 with a concrete error_type. The trigger mutation does NOT surface these — it just returns 201 with no capsuleRecipeJob. Always preview first if you can't trust the inputs.

See jaz-api Rule 143 (silent-null failure mode + diagnosis sequence), Rule 144 (closed enum on recipeName), Rule 150 (RECIPE_INVALID_BASE_TRANSACTION_TYPE — preview-only, NOT trigger), Rule 156 (ERR_RECIPE_ACCOUNT_CURRENCY_MISMATCH), Rule 157 (x-accountClass slot constraint).

Recovery flow (when capsuleRecipeJob is null on the response):

1. Re-run preview_capsule_recipe with the same recipeName + inputs. The 422 you get back is the exact reason the trigger mutation silently nulled. Fix the input and retry.
2. Poll search_background_jobs --filter '{"baseTransactionResourceId":{"eq":"<id>"}}' — if a FAILED job exists, errorDetails has the publish failure. If no job exists, the publish never queued (validation rejected pre-queue).
3. Job status FAILED → resume_capsule_recipe (≤3 attempts) OR rollback_capsule_recipe(dryRun=true) first, then rollback_capsule_recipe(dryRun=false). Record the judgment: jot(kind: RECOVERY) naming resume or rollback and the basis.
4. Capsule wasn't created via the recipe engine → rollback returns 422 RECIPE_ROLLBACK_JOB_NOT_FOUND; use delete_capsule for legacy capsules.

DO NOT use server-side execution for fx-reval — Jaz auto-handles ALL period-end IAS 21.23 FX translation; double-posting risk identical to the offline execute_recipe(recipe: 'fx-reval') warning.

Template Customization (optional) — templateOverrides

A recipe generates text for the capsule title/description, each scheduled posting's label/description, the journal-line memos, and the schedule reference. To customize any of those, pass templateOverrides alongside inputs on preview_capsule_recipe and on the capsuleRecipe trigger payload:

capsuleRecipe: {
  recipeName: "LOAN_AMORTIZATION",
  inputs: { ... },
  templateOverrides: [
    { slotKey: "capsule.title", template: "Loan {{loanReference}}" },
    { slotKey: "leg.description.payment", template: "" }   // empty string clears a nullable slot
  ]
}

Discovery + rules:

• Discover the slots first: get_capsule_recipe(name).data.versions[].templateSlots[] lists each slotKey, its uiLabel, defaultTemplate, supportedVariables, and nullable. Send only the slots you change.
• Each slotKey MUST be one the recipe publishes; every {{var}} in template MUST be in that slot's supportedVariables; template ≤2000 chars; an empty template clears a nullable slot (omit the entry to keep the default; a non-nullable slot rejects a blank).
• Preview is the gate. preview_capsule_recipe surfaces override mistakes as clean 422 ERR_RECIPE_OVERRIDE_* codes. On the trigger path, an invalid override falls under the same best-effort silent-null behavior as everything else in the payload (see the three gates above) — so preview before you trigger.
• CLI: clio capsule-recipes get <name> prints the slots; clio capsule-recipes preview --recipe <name> --inputs '{...}' --template-override capsule.title='Loan {{loanReference}}' (repeatable).
