description	Build a browsable type specimen that sets candidate typefaces in the product's own words, so a font is chosen against real copy rather than "Hamburgefonstiv". Loads families from Google Fonts, shows a weight ladder, prose, a data table, list rows, small caps, glyph coverage and variable axes per family, measures WCAG and APCA for the chosen background/text pair, and lets any specimen text be edited in place — one edit, every family. Use when picking a typeface, comparing shortlisted fonts, checking a font's Cyrillic or symbol coverage, or proving a font works for a specific interface before it enters the token set. Triggers on choose a font, pick a typeface, compare fonts, type specimen, font shortlist, does this font have Cyrillic, font pairing, which font for this dashboard, шрифтовой стенд, выбрать шрифт.

type-specimen

Announce at start: "I'm using the humane:type-specimen skill to pick a typeface against the product's own copy."

Choosing a typeface from a foundry's own specimen tells you the font can be made to look good. It does not tell you whether your numbers align in your table at your size. This skill builds a single self-contained HTML page that sets every shortlisted family in the copy the product actually ships — the same headline, the same price column, the same empty-state sentence — so the comparison is between candidates doing the real job.

The page is standalone: one HTML file, no build step, no dependencies. Families load from the Google Fonts CSS API at view time.

Where output goes

The built specimen page and its specimen.json go in .design/specimen-<name> — the setup setting, defaulting to corpus_root. Pass -o to put them elsewhere; never let them default to the current working directory, which writes into whatever tree the agent happens to be standing in. setup/references/paths.md owns the full table.

Quick reference

You want to	Run
Start a specimen	scripts/specimen init -o spec.json --locale ru --context "..."
Feed it the brief	scripts/specimen texts spec.json --from-file README.md
See what still needs writing	scripts/specimen texts spec.json
Write a slot	scripts/specimen texts spec.json --set headline="..."
Validate without building	scripts/specimen check spec.json
Build and open it	scripts/specimen build spec.json

Config field reference: references/config.md.

The flow

1. Take the brief

Ask what the type is for, in one or two sentences: the product, the surface (dashboard, receipt, marketing page), the reading distance, and the scripts it must cover. Store it — --context for a sentence, --from-file for a README, a spec, or a page of real product copy.

The brief is stored in the config and never shipped to the built page. It is for whoever writes the copy, and a specimen often gets shared before the product is announced.

2. Write the ten slots from real copy

The page renders ten text slots. Each has a fixed shape, enforced by specimen check:

Slot	Shape	What it has to prove
display	one line	The largest thing on the screen, at its real length
timer	one line	Figures — lining, tabular, and whether they align
headline	one line	A heading in its real register
weights	one line	One phrase repeated down the weight ladder
prose	many lines	A paragraph at reading size, set in columns
caps	one line	Uppercase, and whether small caps exist
rows	many lines, name :: value	Label/value pairs, right-aligned
table	many lines, 3 :: cells	A real data row
tableHead	one line, 3 :: cells	The column labels above it
alphabet	many lines	Every script the product ships

Take the strings from the product, not from your head. A specimen written in invented copy tests an invented product. Where ux-writing owns a string, use its wording verbatim; where the product exists, lift from the interface. If neither is available, say so in the handoff rather than passing invention off as evidence.

Two rules that decide whether the page is useful:

• Longest realistic, not average. A price column proves nothing at 9 ₽. Set the widest figure the product can produce, because that is the one that breaks the layout.
• The alphabet slot must cover every script. A Cyrillic product whose specimen shows only Latin has tested half the font. scriptRange makes the page flag families that ship without the script — set it (U\+04 for Cyrillic; --locale ru does this for you) or the badge never appears.

3. Choose the families

One family per line, name :: group :: note. Names must match the Google Fonts catalogue exactly — a typo produces a "failed to load" badge, not an error. group filters the grid and must be declared in groups; note is for the foundry or whatever else you need to remember at a glance.

Six to ten candidates is the working range. Past that the grid stops being a comparison and becomes a catalogue, which is the thing you were trying to escape.

4. Build, then judge in the page

scripts/specimen build spec.json writes the HTML and serves it on 127.0.0.1. It serves rather than opening a file:// URL on purpose: the share link is copied via the clipboard API, which a file:// page does not get.

In the page:

• Edit any specimen text in place. Click a line inside any card, type, then Tab or click away. Escape reverts. The edit writes back to the single source of truth, so it lands in every family at once — the point being that you compare families, never accidentally compare copy. Table and row cells edit one cell at a time; everything else edits whole.
• Set the real background and text colours before judging anything. A typeface reads differently at a different contrast, and the panel reports WCAG and APCA for the pair as you go.
• Expand a card for prose, tables, glyph coverage and variable axes. The collapsed card answers only "is this worth a look".
• Copy link encodes the whole state in the URL, so a shortlist can be sent to someone else exactly as you left it.

5. Hand off

A chosen family is a token, not a note in a document. Hand the name and the weights you actually used to design-tokens, which owns the token set from that point on. If the pair you chose failed the contrast bar, that is design-tokens' tokens contrast to resolve — do not fix it by eye in the specimen and call it done.

Honesty guards

• A specimen is evidence, not a verdict. It shows how families behave in the product's copy. It cannot tell you which is right, and neither can this skill — report what differed and let the person choose.
• Do not rank families on a score. There is no number here. If you find yourself writing "Onest: 8/10", you are inventing precision the page did not measure.
• Never claim coverage you did not look at. The glyph-coverage grid tests the characters in glyphSets and nothing else. A family that passes there may still be missing something you never asked about — say which sets were checked.
• A "failed to load" badge is not a judgement of the font. It usually means the name does not match the catalogue. Check the spelling before reporting a family as unavailable.
• The contrast readout describes the pair you set, not the page. Change the background and it changes. Cite the colours alongside the number or the number means nothing.

Claude Code extras: with the humane plugin installed the specimen sits between humane:jtbd (who reads this, and where) and humane:design-tokens (where the chosen family lands). Slot copy should come from humane:ux-writing rather than being written fresh here, and a built page is a reviewable artifact — hand it to humane:respondent-panel when you want to know how the type lands rather than whether it is correct.

Conflicts

The user's explicit words win, then this skill's rules, then the project's existing system, then taste. If the project already has a typeface in its tokens, say so and build the specimen with it included as a baseline rather than quietly proposing a replacement.
