Products · Tech pack
A bill of materials, points of measure, construction notes and callouts, as an editable XLSX or PDF. What it will not do is invent a number: every value your production team still has to sign off is left visible, so what you review is a draft rather than a guess wearing a spec's clothes.
The wrong artefact
Ask most generative tools for a garment spec and a photoreal image comes back, because that is what they are good at. On a build package it is not a weaker answer, it is the wrong kind of thing, and it fails in three specific ways.
The one thing a cutter needs to see is exactly what a soft render smooths away.
A generated garment resolves a join it was never told about. The factory builds the invention.
Nothing in a render is to measure, so a pocket that reads right on screen is a re-sample in the flesh.
So the package is drawn the way a factory is used to receiving one: closed line-art flats front, back and detail, with the measurement callouts leadered off them, and the tables carrying the instruction. The flat is the index. The tables are what gets built.
How a pack is built
A specification is not a description of a garment. It is a set of numbers a stranger in another country will cut against, so the interesting question is never what the document says: it is which parts of it are known and which are still yours to decide.
In words, from a sketch, or from a photograph of a sample on the table. What matters is the construction you intend rather than the styling: how it closes, how it is joined, where it is meant to sit on the body.
Points of measure, the graded size run and the increments between sizes are arithmetic against a base, not prose. That is the half a language model should never be improvising, so it is calculated and laid out as a table somebody can check line by line.
Line art, front and back, with the callouts pinned to the seams and trims they refer to. A callout that cannot be found on the drawing is a note, and a note is what gets ignored on a factory floor.
Supplier, fabric reference, exact colour standard, tolerance: the values only your production team can sign off are left marked rather than filled with something plausible. An invented number is worse than a blank, because a blank gets questioned and a number gets cut.
What it will not do is invent a value nobody gave it.
One reading
The test is whether a factory could read it two ways. Where it could, the package removes the choice - and where a value genuinely is not yours to invent, it is left marked for you to confirm rather than filled in with something plausible.
Measurements are computed against the size-rule table and checked back against the tolerance band, not recalled from anywhere. That is the difference between a spec that proves it was worked out and one that reads like it was.
Four documents, four jobs
The four files a garment cannot be made without: the pack that specifies it, the sheet that says how it is cut and joined, the graded size run, and the trim cards somebody signs. Four real programmes, one of each. Page through any of them, then download the file - the XLSX opens with typed cells and formulas, not a picture of a table.

Who reads the pack
A pack is the one document every one of these people has to agree on, and each of them opens it looking for something different.
The drawing has to survive being turned into instructions without losing the thing that made it worth making. Getting a first pack out in an afternoon means the conversation with the factory starts from a document rather than from a description.
A supplier quotes against what is written down, so anything vague becomes either a question or an assumption, and assumptions turn up in the sample. Blanks that are visibly blank get answered before costing; invented values get discovered after cutting.
Fit is a conversation held in measurements across sizes, and it only works if the increments are consistent. A graded run laid out as typed cells can be corrected and re-issued; one laid out as a picture of a table has to be rebuilt.
Without a technologist on staff, the pack is usually the thing standing between a good sample and a bad one. Having the structure a factory expects, with the unknowns marked, is what makes a first order a negotiation instead of a gamble.
