/as:sif-to-csv — SIF to CSV Converter

Harness note: use /as:<skill> on Claude Code and $<skill> on Codex. Resolve <skill-root> as the directory containing this loaded SKILL.md and <plugin-root> as the plugin root that contains skills/, and use equivalent native tools when host tool names differ.

Converts a SIF input from a dealer or procurement system into a human-readable preview and canonical product rows. Translates field codes, expands options and attributes, calculates pricing, and computes totals.

When to Use

• Received a SIF file from a dealer and need to review it as CSV data
• Importing dealer pricing back into your FF&E schedule
• Comparing a dealer quote (SIF) against your original specification
• Loading dealer data into the project's product-library.csv

SIF Format Reference

SIF is a text-based key-value format. Each line is CODE=VALUE, terminated by CRLF. Products are separated by records starting with PN=.

Core fields

Code	Name	Description
SF	Specification File	Project reference (header)
ST	Specification Title	Display title (header)
PN	Product Number	SKU — starts a new record
PD	Product Description	Product name
MC	Manufacturer Code	3-5 char code
MN	Manufacturer Name	Full name
QT	Quantity	Integer
NT	Quantity (alt)	Some systems use NT instead of QT
GC	Category / Group Code	Product category
G0	Vendor / Group ID	Vendor identifier

Pricing fields

Code	Name	Description
PL	List Price	Unit list price
P1-P5	Price Tiers	Alternate price tiers
I1	Unit List Price (Cyncly)	Cyncly Worksheet
I2	Purchase Price (Cyncly)	Cyncly Worksheet
S- / S%	Sell Discount %	Sell = PL - (PL × S- × 0.01)
P% / B%	Purchase/Buy %	Cost = PL × (P% × 0.01)

Product detail fields

Code	Name	Description
TG	Side Mark / Tag	Room, area, or project tag
ON / OD	Option	Number + description pair
AN / AD	Attribute	Number + description pair
WT	Weight	Product weight
VO	Volume	Product volume
PRC	Product Category (Cyncly)	Cyncly category

Link fields

Code	Name	Description
ProductURL	Product Page URL	Link to product page
ImageURL	Product Image URL	Link to product image
PV	Picture Path	Local file path

Alternate manufacturer codes

System	Code	Purpose
Standard	MC	3-5 char manufacturer code
Cyncly	MG	Manufacturer code (replaces MC)
CET	EC	Manufacturer code (alt)

Step 1: Accept Input

SIF file:

/as:sif-to-csv ./dealer-quote.sif

Pasted SIF content:

/as:sif-to-csv
SF=Project Alpha
ST=Dealer Quote - March 2026
PN=670
PD=Eames Lounge Chair and Ottoman
MC=HMI
QT=3
PL=5695.00
S-=42
TG=Executive Lounge
OD=Santos Palisander / Black MCL Leather

Step 2: Parse SIF

Read the file and parse each record:

1. Header fields: Extract SF and ST
2. Records: Split on PN= boundaries
3. For each record, extract all fields
4. Detect manufacturer code variant: look for MC, MG, or EC — normalize to brand name
5. Detect price variant: look for PL, P1, I1 — use whichever is present
6. Detect quantity variant: look for QT or NT
7. Calculate derived values:
   • Sell Price: PL - (PL × S- × 0.01) if discount present
   • Net Price: PL × (P% × 0.01) if purchase % present
   • Extended List: PL × QT
   • Extended Sell: Sell Price × QT

Manufacturer code expansion

MC	Brand	MC	Brand
HMI	Herman Miller	BLU	Blu Dot
MKN	MillerKnoll	DWR	Design Within Reach
KNL	Knoll	FRH	Fritz Hansen
STC	Steelcase	VIT	Vitra
HAW	Haworth	ARP	Arper
TEK	Teknion	FLS	Flos
HUM	Humanscale	LPO	Louis Poulsen
KIM	Kimball	ART	Artemide
OFS	OFS	HBF	HBF
GEI	Geiger	BRN	Bernhardt

For unknown codes, keep as-is and flag.

Options and attributes

• Multiple ON/OD pairs → concatenate into "Options" column, separated by |
• Multiple AN/AD pairs → concatenate into "Attributes" column, separated by |
• If AN=DIM, parse dimension string back into W/D/H if possible

Step 3: Present Preview

## SIF Import: Project Alpha — Dealer Quote March 2026

3 records parsed from dealer-quote.sif

| # | SKU | Product | Brand | Qty | List $ | Disc % | Sell $ | Ext Sell | Options | Tag |
|---|-----|---------|-------|-----|--------|--------|--------|----------|---------|-----|
| 1 | 670 | Eames Lounge Chair | Herman Miller | 3 | $5,695 | 42% | $3,303 | $9,909 | Palisander/Black | Exec Lounge |

**Totals:**
- List: $22,147 · Sell: $18,086 · Savings: $4,061 (18.3%)

Step 4: Output

Show the parsed table in Markdown. For persistence, write only to the nearest project-root product-library.csv. Read ../../schema/product-schema.md, ../../schema/csv-conventions.md, and ../../schema/sif-crosswalk.md. Map by these named fields:

• Link ← ProductURL; Product Name ← PD; SKU ← PN; Brand ← expanded MC
• Category ← GC or PRC; dimensions ← AD where AN=DIM; Weight ← WT
• List Price ← PL/P1/I1; Sale Price ← calculated sell price; Selected Color/Finish ← OD
• Image URL ← ImageURL; Tags ← TG; Status ← quoted; Source ← sif-to-csv
• Notes ← From SIF: {ST}. Discount: {S-}%. Qty: {QT} · Ext: ${ext_sell}

Preview the complete batch's row mappings, totals, warnings, and target path, then use the single confirmation gate. After approval, serialize all complete rows as one JSON array and invoke python3 "<plugin-root>/skills/master-schedule/scripts/csv-library.py" append product --project <project-root> --row-json <batch.json> exactly once. The helper validates the complete batch and library before one atomic replacement; never loop per row.
