AI agent workflows for Everyday life & family admin

Build spec

1 agent — 1 bill-reading agent. The urgency rule is a user-defined SpEL tool, and the branching, the payment approval and the filing are workflow nodes — not extra agents.

System prompt (paste-ready)

You are a household bill assistant for {{family}}. From an incoming message (email, SMS or a forwarded WhatsApp), extract {biller, account_ref, amount, currency, due_date, billing_period, channel}. Use ONLY what the message actually says — if the amount or due date is not clearly stated, return that field as null and set needs_check=true with a one-line reason. NEVER estimate a due date from a previous bill and never round an amount. You do not pay anything and you do not confirm anything as paid: you only prepare a reminder and a draft payment for a human to approve. Write reminders in plain, warm language, in the household's preferred language, with the biller, the amount and the date — no lectures, no urgency theatre beyond the label the workflow gives you.

Agent roles & model tiers

• Bill reader (per message) — Economy tier — this runs on every bill, SMS and forward the household receives, so its per-call cost is the only cost that scales

  Extract the bill fields into strict JSON. Null for anything not explicitly stated, needs_check=true with a reason. No estimating, no rounding, no inferring from history.

• Weekly digest writer (once a week) — Standard tier — runs once per week over the whole list, so a better model here is nearly free

  Write one short weekly household digest from the filed bills: what is due this week with dates and amounts, what was paid, and anything flagged needs_check. Use only the filed records; never invent a bill and never state something was paid unless the record says so.

Guardrails

• No payment is ever made by the agent. A Razorpay UPI request can be prepared with the biller and amount pre-filled, but it passes the Approval node and needs your tap — recurring bills included, every time
• Nothing is inferred: a missing amount or due date is returned as null with needs_check=true, never estimated from last month's bill
• Your bills, account numbers and payment history stay in your own tenant's Knowledge base. Nothing is forwarded to a relative, an accountant or any third party without an Approval step
• Idempotent per (biller, billing_period) — the same bill arriving by both email and SMS produces one entry and one reminder, not two

Cost strategy

Cost tracks message volume, not household size. The reader runs on every incoming bill/SMS/forward, so it sits on the economy tier with a hard token cap and a fallback model configured — if the primary is unavailable the reminder still goes out, which matters more here than prose quality. The one standard-tier call per week is the digest. Reminder sends are channel cost, not model cost: keep the routine ones on WhatsApp/SMS and reserve the Voice call for the URGENT branch only.

Output & delivery

Each bill becomes a structured record filed in your household Knowledge base; the `bill_urgency` SpEL tool labels it, the Condition node routes URGENT to an immediate WhatsApp (and optional Voice call) while SOON joins the weekly digest; any payment is a Razorpay UPI request that waits at the Approval node for your tap, and an Email copy of every reminder gives you a record outside chat.

Build spec

2 agents — 1 cheap extractor (runs once per document via the Loop node) + 1 writer that composes the single monthly message. The lead-time rule is a user-defined SpEL tool; the branch, the approval and the payment request are workflow nodes. · Pattern: Map-reduce: Loop over your filed documents (map) → one composed reminder (reduce) → human approves anything binding

System prompt (paste-ready)

(Extractor) Read ONE household document and return strict JSON {doc_type, holder, identifier, expiry_date, issuing_body, renewal_notes, source_file}. Take every value from the document itself — if the expiry date is not printed on it, return null and set needs_check=true. NEVER infer an expiry from a typical validity period ('passports are ten years'), and never state a fee or a procedure that is not written in the document or in a previously filed renewal receipt. You are indexing paperwork, not advising on it.

Agent roles & model tiers

• Document extractor (per document, in a Loop) — Economy tier — it runs across the whole folder every month, so this is the single dominant cost lever

  Extract {doc_type, holder, identifier, expiry_date, issuing_body, renewal_notes} from ONE document as strict JSON. Null + needs_check=true for anything not printed on the document. No inferred validity periods, no invented fees.

• Reminder writer (once per sweep) — Standard tier — one call a month, so this is where the reasoning budget goes

  Compose ONE warm, short message covering only the documents inside their reminder window: what expires, when, what you'll need to renew it, and what it cost last time according to the filed receipt. Say 'per your filed receipt' when quoting a past amount. If a document was flagged needs_check, list it plainly as 'we couldn't read the expiry — worth a look' rather than skipping it.

Guardrails

• The agent reminds; it never renews. Every payment (Razorpay UPI) and every submission or document upload to a portal passes the Approval node first
• Expiry dates come from the document, not from general knowledge about how long that document usually lasts — unreadable means needs_check, never a guess
• Costs and procedures are quoted only from your own filed receipts, always attributed ('per your filed receipt'), never asserted as the current official fee
• Your policies, licences and identity documents stay in your own tenant. Nothing is shared with an agent, a broker or a relative without an Approval step

Cost strategy

Linear and tiny: N documents × one economy-tier extraction + ONE standard-tier compose, once a month. Because the extractor runs across the whole folder, keep it on the economy tier with a strict token cap and a fallback model — a reminder that arrives in plainer prose beats one that doesn't arrive. If the folder is large, run the map in Parallel batches: same per-document cost, finishes sooner.

Output & delivery

The Loop maps the cheap extractor over your filed documents → the `renewal_window` SpEL tool labels each one against YOUR lead time → the Condition node drops everything QUIET → the writer composes a single WhatsApp listing what's due, the checklist and the last known cost → any payment or portal submission waits at the Approval node for you.

Build spec

2 agents — 1 economy-tier classifier on every message + 1 task extractor that runs only on messages classified ACTION. The digest, the urgency label and the approval are nodes and a SpEL tool, not agents. · Pattern: Cheap filter → expensive extraction only on what survived the filter

System prompt (paste-ready)

(Classifier) Classify ONE school-group message as ACTION, INFO or NOISE. ACTION means a parent must DO something by a date — sign, pay, send, attend, bring. INFO is worth knowing but requires nothing. NOISE is greetings, photos, thanks, forwards. Return {class, confidence, child_hint}. When you are unsure between ACTION and INFO, choose ACTION — a false alarm costs a glance, a missed consent form costs a school trip. Never summarise away a date, an amount or a child's name. You never reply to the group.

Agent roles & model tiers

• Message classifier (every message) — Economy tier — this is the highest-volume call in the whole guide, running on hundreds of messages a day; nothing else affects the bill as much

  ACTION / INFO / NOISE plus confidence, in strict JSON. When torn between ACTION and INFO, pick ACTION. Never drop a date, an amount or a name.

• Task extractor (only on ACTION) — Standard tier — a small fraction of messages reach it, so the better model is affordable here

  Turn one ACTION message into {task, child, due_date, requires (signature|payment|item|attendance), amount, quoted_text}. Quote the original line for anything factual. If the deadline is vague ('by next week'), keep it vague and say so — never invent a specific date.

Guardrails

• The workflow never posts to the school group or replies to a teacher on its own. Replies are drafted; sending passes the Approval node
• Fees are never paid automatically — a Razorpay UPI request is prepared and waits for your tap
• Dates and amounts are quoted from the original message, never paraphrased or inferred; a vague deadline stays vague and is flagged as vague
• Group content and your children's names stay in your own tenant's Knowledge base. Nothing is forwarded outside the family without an Approval step
• Bias the classifier toward ACTION on low confidence — the cost of a false alarm is a glance; the cost of a miss is a child left out

Cost strategy

This is the clearest cost-routing case in the pack: hundreds of messages a day hit the classifier, and perhaps five a week reach the extractor. Put the classifier on the economy tier with a hard per-message cap and a fallback model; put the extractor on the standard tier. Getting that split right is worth more than any prompt tuning. Digests are one message a day on a channel you already pay nothing extra for. Sarvam handles the group's mixed-language messages so a Hinglish note about a consent form doesn't slip through as noise.

Output & delivery

Every message is classified cheaply → NOISE is dropped, INFO waits for the digest, ACTION goes to the extractor → the `school_task_priority` SpEL tool ranks the tasks by YOUR thresholds → an evening WhatsApp digest and a morning-of nudge go to you (never to the group) → fees and form submissions wait at the Approval node, with a weekly Email copy to the second parent.

Build spec

2 agents — 1 filing agent (runs when you send a photo) + 1 retrieval agent (runs when you ask a question). Sharing is an Approval node, not an agent decision. · Pattern: File-on-ingest, answer-on-ask — two small agents over one Knowledge base

System prompt (paste-ready)

(Filing) You file household documents. From a photograph, return {suggested_name, doc_type, parties, identifiers[], issue_date, expiry_date, one_line_description, sensitivity (NORMAL|IDENTITY|FINANCIAL)}. Read only what is visible — if the photo is cut off or blurred, say which field you could not read rather than filling it in. Mark sensitivity IDENTITY or FINANCIAL whenever the document carries a government identifier, an account number or a card number. You never send this document anywhere; you only file it.

Agent roles & model tiers

• Filing agent (per document) — Economy tier — short, structured extraction, and it runs every time a family member photographs something

  Extract the filing fields as strict JSON, marking sensitivity. Unreadable fields are named as unreadable, never filled in. No sending, no sharing.

• Retrieval agent (per question) — Standard tier — it must be careful about saying 'I don't have that', which is the answer that actually protects you

  Answer household questions using knowledge_search over the filed documents ONLY. Always cite which document you read. If the answer is not in a filed document, say plainly that it isn't filed — never answer from general knowledge about how such documents usually work.

Guardrails

• No document leaves your tenant without passing the Approval node, and documents marked IDENTITY or FINANCIAL take the stricter approval path via the `share_risk` rule
• Every approved share is logged against the document — recipient, channel, date — so you can always answer 'who has a copy of this?'
• The retrieval agent answers only from filed documents and cites them; when something isn't filed it says so instead of reasoning from what such a document usually contains
• Unreadable fields in a photograph are reported as unreadable, never inferred — a wrong identifier confidently filed is worse than a gap

Cost strategy

Both agents are single-call and event-driven, so there is no batch multiplier — cost tracks how much your household actually files and asks. Keep the filing agent on the economy tier (it is the higher-volume of the two and the task is structured extraction) and the retrieval agent on the standard tier, because the valuable behaviour there is a careful 'that isn't filed', which weaker models are worse at. Configure a fallback model on retrieval so a question during a bank visit still gets answered.

Output & delivery

A photographed document is named, dated, classified for sensitivity and filed into your household Knowledge base; questions are answered from those filed documents with a citation; any outbound copy is drafted with the right attachment and recipient and waits at the Approval node — stricter for identity and financial documents — with every approved share logged back against the document.
