Return / RMA Slip PDF Generator

This skill produces the printable slip that closes out a transaction at the returns desk. You collect the final, already-confirmed values, then run the bundled slip_pdf.py script to render the slip to a PDF using reportlab. Do not hand-draw the PDF, write your own rendering code, or invent amounts — every value comes from earlier steps (Policy Agent ruling, Membership MCP, Warehouse MCP, and the prorated-refund-calculator skill).

When to use

Use this skill last, after every amount is final:

• the eligibility / warranty ruling is decided (Store Policy Agent),
• any membership refund is computed (prorated-refund-calculator),
• any upgrade settlement / net-due is computed (prorated-refund-calculator),
• the customer has agreed to the outcome.

Do not use it to decide anything — it only renders the agreed result.

Slip types

Set slip_type to the right label:

• WARRANTY SWAP — defective item replaced under warranty.
• RETURN / REFUND — item returned for a refund.
• EXCHANGE / UPGRADE — item swapped for a different model with a price difference.
• MEMBERSHIP CANCELLATION — BlastPass cancelled (often combined with the above).

Workflow

1. Assemble the confirmed values

Build a JSON object with the final values. Every field is optional except those that apply to this transaction. Keep amounts formatted to 2 decimals with a $ prefix.

Field	Meaning
slip_type	one of the labels above
rma_ref	RMA / reference number
date	YYYY-MM-DD
store / associate	store name/number and associate/desk
customer_name	customer name
member_id / member_tier	BlastPass id and tier
items	list of [item, sku, disposition, amount] rows
settlement	list of [label, amount] rows (upgrade difference, refund applied as credit, etc.)
net_label / net_amount	e.g. NET DUE FROM CUSTOMER / $23.34, or REFUND TO CUSTOMER / $76.66
notes	free-text notes

2. Run the bundled script

Pass the JSON to slip_pdf.py:

python3 slip_pdf.py --slip-json '<json>' --output blastbox_slip.pdf

For the upgrade-settlement example (defective base console → MEGA edition, with a BlastPass refund applied as store credit):

python3 slip_pdf.py --output blastbox_slip.pdf --slip-json '{
  "slip_type": "EXCHANGE / UPGRADE",
  "rma_ref": "RMA-OMEGA-1024",
  "date": "2026-06-07",
  "store": "BlastBox #214 - Seattle",
  "associate": "Associate Desk",
  "customer_name": "Jordan Pixel",
  "member_id": "MEGA-BLAST-1024",
  "member_tier": "BlastPass Plus Extra",
  "items": [
    ["BlastBox Omega (defective)", "SKU-OMEGA", "Warranty credit", "$399.99"],
    ["BlastBox Omega MEGA Edition", "SKU-OMEGA-MEGA", "Upgrade (new)", "$499.99"]
  ],
  "settlement": [
    ["Upgrade difference ($499.99 - $399.99)", "$100.00"],
    ["BlastPass Plus Extra refund applied as store credit", "-$76.66"]
  ],
  "net_label": "NET DUE FROM CUSTOMER",
  "net_amount": "$23.34",
  "notes": "Manufacturing defect confirmed within 30 days - no restocking fee. BlastPass Plus Extra (MEGA-BLAST-1024) cancelled; 8 unused months prorated."
}'

The script writes the PDF and prints WROTE blastbox_slip.pdf. If the JSON is long, you may write it to a file and pass --slip-file slip.json instead.

3. Report

• Confirm the PDF was written and give its filename.
• Restate the net amount (due or refunded) and the slip type.
• Offer to email or reprint the slip if needed.

Notes

• The script uses reportlab (the available PDF library). No network calls.
• The layout fits a single page for a normal transaction.
• Pass plain text in the values; the script escapes & for you.
