--- name: fabric-care-decoder description: Reads a care label, described as symbols or as fibre composition and garment type, and returns the wash temperature and cycle, detergent type, drying method, ironing heat, expected shrinkage, pilling risk, and which part of the label is overcautious. Use when someone cannot read a care symbol, asks if something is machine washable, wants to know if a garment will shrink or pill, or has a fibre blend with a missing or damaged tag. Decodes care instructions only; it does not track laundry scheduling or judge how a garment fits or looks. license: MIT metadata: title: Fabric & Care Decoder publisher: Stylin homepage: https://stylinai.com/skills/fabric-care-decoder.html version: "1.0.0" --- # Fabric & Care Decoder Turns a care label — read as symbols, as printed words, or as a fibre-content percentage with no label at all — into concrete laundry instructions: temperature, cycle, detergent, drying, ironing, and the shrinkage and pilling risk to actually expect. It also flags where the label is stricter than the fibre requires. ## When to use this - A care label uses symbols with no words and the user cannot read them. - The tag is missing, cut out, or worn illegible, but the user knows or can guess the fibre content. - Someone wants to know whether a garment is safe to machine wash, or whether it will shrink or pill. - A new dark or bright garment needs a bleeding and colour-transfer check before its first wash. - The label instructions look contradictory or oddly strict and the user wants to know which parts actually matter. **Not this skill:** building a weekly wash schedule around household size and drying capacity — that is `laundry-schedule-builder`. This skill tells you the rules for one garment; that skill tells you when to run the load. ## What to ask for Required: - **What the label says.** Either a description of the symbols (shape, dot count, bars, crosses), the printed words, or, if there is no label, the fibre composition percentages and the garment type. - **Garment type and construction.** Knit or woven, lined or unlined, structured (blazer, coat) or unstructured (t-shirt, blouse). Construction changes the dry-clean-only judgment call in step 6. Helpful but optional, with the default assumed when missing: - **Colour and whether it is new.** Default: assume a first wash if the user does not say otherwise, and flag bleeding risk for anything dark, bright, or hand-dyed. - **Embellishment** — sequins, beading, foil print, structured shoulder pads, bonded seams. Default: assume none if not mentioned, but ask directly if the garment type suggests otherwise (eveningwear, outerwear with a laminated shell). - **Whether it has been washed before, and what happened.** Default: no prior history; treat as first wash. Do not ask for the brand, the price, or where it was bought — none of that changes the care rules. ## Procedure 1. **Determine the input type, and if symbols were given, work out which system they belong to first.** Care symbols come from two different standards — ISO 3758 (GINETEX), used internationally, and ASTM D5489, used in the US — and they are not always interchangeable (see the glossary's system note and the "How to tell which system a label is using" section at the top of `reference/care-symbol-glossary.md`). A wash tub with a printed number (30/40/50/60/70/95) is ISO/GINETEX; a wash tub with only dots is ASTM. Use whichever cue is available — the tub symbol, the garment's country of sale, English-only wording, Fahrenheit units — before reading dot counts off the drying symbol, and say which system you assumed in the output if it was not stated directly. Once the system is settled, work from `reference/care-symbol-glossary.md`. If given only fibre composition and garment type with no label, skip to step 2 and build the recommendation from fibre defaults, then label the whole output "no label — built from fibre content" in the assumptions line. 2. **Set the wash temperature and cycle.** From the tub symbol's printed number or dot count, and its bar count, or, with no label, from the most heat-sensitive fibre in the blend (see the blend rule in the reference file: care follows the most sensitive fibre, not the majority one). Wool, silk and anything with elastane cap at 30°C on a delicate cycle regardless of what a majority-cotton or majority- polyester blend partner would otherwise tolerate. 3. **Choose the detergent, and read the bleach triangle.** Standard detergent for cotton, linen, and synthetics on a normal or permanent-press cycle. A wool- or silk-specific detergent (no enzymes, no optical brighteners) for anything hand-wash or delicate-cycle: the proteases in an ordinary biological detergent cannot distinguish stain protein from fibre protein, so they degrade wool and silk over repeated washes and the damage is not repairable. No fabric softener on technical or moisture-wicking synthetics — it deposits a residue that blocks the fibre's wicking channels, and the effect accumulates. Then read the bleach triangle and report it: empty means any bleach, two diagonal lines mean oxygen bleach only, a cross means none. **On wool, silk, elastane and dyed synthetics, report "no chlorine bleach" even if the label permits it** — hypochlorite attacks protein fibres and elastane directly. 4. **Set drying.** A circle-in-square is tumble dry — read its dot count for heat (see the system note in step 1: three dots is an ASTM-only tier). A plain square with lines and no circle is natural drying — line dry, flat dry, or drip dry, per the line pattern in the glossary — and a crossed-out circle means air dry only, so move to the natural-drying square. On fibre defaults with no label: air dry flat for wool, viscose/rayon, and anything loosely knitted — wool and loose knits stretch under their own weight when hung wet, and viscose is at its weakest wet and will stretch out of shape on a hanger even as a woven. Line or hang dry for cotton and linen wovens. Low tumble for synthetics with elastane content over roughly 5 percent. Medium tumble acceptable for plain cotton and polyester. 5. **Set ironing heat, or rule it out.** Read the iron symbol's dot count, or apply fibre defaults: high heat for cotton and linen, medium for wool and polyester (press cloth for wool), low for acetate, silk and elastane blends. Rule out ironing entirely for sequins, foil prints, PU or rubberised coatings, and anything with a crossed-out iron symbol — use steam from a distance instead if creases need addressing. 6. **Resolve dry-clean-only against the fibre.** A dry-clean-only label means one of two different things and the procedure must say which: (a) the fibre or dye genuinely cannot survive water (silk with unstable dye, wool with a structured shoulder, bonded or laminated seams), in which case follow it; or (b) the garment is a simple unstructured knit or woven in a washable fibre and the label is a liability disclaimer rather than a fibre requirement. Call case (b) explicitly in step 8, and still give the label-following instruction as the safe default — do not tell the user to ignore a dry-clean-only label outright, only to note that a cautious hand wash is a plausible alternative if they choose to risk it. 7. **State shrinkage and pilling risk as a range tied to construction, never as a single number.** Pull the dominant fibre's row from the reference table, pick the woven or knit column to match the garment, and adjust for blend percentage. **Always give a range and name what would push the garment to each end of it** — pre-shrunk or resin-finished sits at the bottom, raw or loom-state at the top. If the user has not said whether the fabric is pre-shrunk, say so in `ASSUMPTIONS` and quote the wider range rather than guessing a finish. If the garment has already been through a hot wash or hot dryer cycle contrary to its label, say the shrinkage has likely already happened rather than warning about a future risk. 8. **Write the overcaution note, and mark it as a judgement.** Compare the label's actual restrictions against what the fibre and construction require. Where an instruction is stricter than the fibre needs, name it and give the likely reason (a dye-stability hedge, a single label printed for a whole product range, a liability hedge on a simple garment). **You cannot know the manufacturer's reason, only infer it — word this as an inference, not as fact**, and keep the label's instruction as the stated safe default in every case. If nothing on the label is stricter than the fibre requires, say so directly. Do not manufacture a note to fill the section. ## Output format Return the result in chat.

Label shows a wash tub with two dots and one bar underneath, an empty triangle with a cross through it, a tumble-dry symbol (circle-in-square) with one dot, an iron with two dots, and no professional-cleaning circle symbol at all. It's a plain button-down, no lining, no embellishment, first wash." Output: ```text CARE READ: Cotton oxford shirt, unlined, plain button-down SYSTEM Dots in the wash tub rather than a printed number, so this is an ASTM / North American label. WASH Temperature: 40°C / 105°F, permanent press cycle (one bar under the tub) Detergent: standard detergent, fine for cotton on this cycle BLEACH None. The crossed triangle rules out chlorine and oxygen bleach alike -- normal for a dark dye, where bleach would strip colour before it lifted a stain. DRY Method: tumble dry, low heat (one dot) IRON Heat: medium, two dots (150°C / 302°F max) DRY CLEAN No dry-clean symbol shown -- machine care only, no professional cleaning needed SHRINKAGE RISK Around 1-3% if the shirt is sanforized, which most shirting is; 5-10% if it is not. Nothing on the label states the finish, so treat 1-3% as likely and 5-10% as the downside case. Oxford is a basketweave and sits looser than a poplin plain weave, so it will not resist relaxation shrinkage on its own -- the finish is what decides this, not the weave. Most of it lands in the first two or three washes, driven by the dryer more than the wash. PILLING RISK Low. Cotton pills readily but the pills shed rather than persisting. Watch collar and cuffs if there is a polyester reinforcement there, since polyester pills are the ones that stay. OVERCAUTION NOTE The label caps the wash at 40°C and the iron at medium (two dots) rather than cotton's usual high-heat tolerance (three dots, up to 200°C). Both restrictions look like they are doing real work rather than hedging: on a navy dyed garment the lower wash temperature slows dye loss, and moderate iron heat avoids scorching a resin or wrinkle-resistant finish on the collar and cuffs. That is an inference from the fibre, colour and construction, not something the label states. Nothing here reads as overcautious. ASSUMPTIONS - Whether the fabric is pre-shrunk was not given, so the shrinkage figure is quoted as both cases. - All other inputs were given directly from the label. ``` ## Edge cases and failure modes - **No label and the user does not know the fibre content.** Ask once for the fabric's feel and behaviour (matte and cool to the touch usually cotton or linen; slightly shiny and slippery usually a synthetic or viscose; springs back when scrunched usually has elastane). Build a provisional recommendation from the most conservative match and label it clearly as a guess in `ASSUMPTIONS`. - **Contradictory symbols**, such as a 40°C wash tub paired with a hand-wash-only icon on the same label. Resolve toward the more restrictive instruction — hand wash at or below 40°C — and note the contradiction rather than silently picking one. - **Leather, suede, fur, or fur-trim.** These are not covered by the fibre table at all. State plainly that they need specialist leather or fur cleaning, not home laundering of any kind, and stop there rather than guessing a wash temperature. - **Sequins, beading, foil print, or bonded/laminated seams.** Override any wash-tub symbol present: hand wash cold at most, no tumble dry, no direct iron contact, regardless of what the fibre content alone would otherwise allow. - **A garment that has already been washed wrong** (shrunk, pilled, felted). Do not offer a fix that does not exist — wool felting and heat-set acrylic shine are permanent. Say so, and give the correct instructions for next time instead of a false remedy. - **A request to decide whether the garment is worth keeping after damage**, or which of several damaged garments to prioritise replacing. Hand off to `wishlist-triage` for a buy decision or `closet-declutter-protocol` for a keep/repair/sell/bin call — this skill only reports the care facts. - **A request to fix how the garment fits after shrinkage**, or whether an alteration can reverse it. Hand off to `tailor-brief` — shrinkage recovery and re-tailoring are a different job. ## Reference files - `reference/care-symbol-glossary.md` — full symbol tables for wash, bleach, tumble dry, natural drying, iron, and professional cleaning, with ISO 3758 (GINETEX) vs. ASTM D5489 called out wherever the two systems differ, plus the fibre shrinkage and pilling reference table. Read this in step 1 for symbol lookups (including which system a label is using) and in steps 2 through 7 for fibre defaults and the blend rule. ## What this skill does not do This skill handles wardrobe logistics, not visual styling. It will not: - Tell you what to wear or whether a garment suits an occasion once it is clean. - Judge how a garment fits, drapes, or suits the person wearing it. - Decide whether a damaged or shrunk garment is worth keeping — that is a declutter or purchase decision, not a care question.
