UX Writing

Announce at start: "I'm using the humane:ux-writing skill to write and review the words inside this product."

The words are part of the interface, not a layer applied to it. A control that names its exact action needs no tooltip; an error that says what to do next needs no support ticket. Clear beats clever, consistent beats varied, and the best error message is the interaction redesigned so the error cannot happen.

What this skill owns, and what it doesn't

Owns: the source wording of every user-facing string, and the decision about what a string must accomplish.

That includes documentation prose — READMEs, docs pages, release notes, onboarding guides. The principles below were written for interface strings and most transfer directly (accuracy, one vocabulary, nothing does double duty, no selling); where a principle is interface-specific it is marked. A doc that contradicts the thing it documents is a HIGH finding, not a typo.

Adjacent concern	Owner
How copy renders — capitalization via text-transform, truncation, smart punctuation, measure	layout-rules (and better-typography if interfaces is installed)
Whether the layout has room for the translated string	layout-rules
Error markup and announcement (aria-invalid, live regions)	nielsen-heuristics for the heuristic; better-accessibility for the implementation
Whether the copy lands with strangers	respondent-panel
Whether a stakeholder objects to the argument	persona-review
Brand voice for marketing surfaces, taglines, transformation claims	brandkit, before-after

This skill writes the words. It does not judge the usability of the flow around them — that is nielsen-heuristics.

Step 0 — Read the evidence before writing a word

This is the step that separates this skill from a style guide, and it is not optional when a corpus exists.

1. Look for <corpus_root>/<slug>/jtbd.json. corpus_root is the setup setting (default ~/jtbd); read the configured value rather than assuming the default, or a user who moved their corpus gets "no corpus found" and copy written from assumption. If one exists, read it. If several projects exist, ask which. If none exists, say so plainly in the output — the copy is then written from assumption, and that is a fact the reader should have.
2. Mine the switch forces, because each one tells you what a specific class of string has to accomplish:

Force	What it means for the copy
anxiety	What a confirmation, a destructive dialog, or a first-run screen must defuse. If the anxiety is "I'll lose my data", the delete dialog says what is recoverable and for how long.
habit	What the old vocabulary was. Name things the way the thing they're leaving named them, or say explicitly that you renamed it.
push	The frustration to name back to them in an empty state or onboarding. Recognition beats persuasion.
pull	The one outcome a primary button should promise. It is usually the verb.

3. Reuse the corpus's own words. evidence.quotes[] is the product's real vocabulary, captured from people who use it. A verbatim noun from a quote beats an invented one every time. When you take a word from a quote, cite the evidence id ([Q2]) beside the string.

Step 1 — Recon the voice you already have

Before writing or changing anything, read the surrounding copy, the product's terminology, its localization files, and any style guide. Preserve intentional character. A difference from generic plain language is a finding only when it creates inconsistency, ambiguity, translation risk, or a tone wrong for the stakes — not merely because it has personality.

Tone flexes with the stakes; voice does not change:

Context	Tone
Success, onboarding, empty states	Warm, can be light
Routine actions, settings	Neutral, minimal
Errors, destructive confirmations	Calm, plain, zero playfulness
Data loss, security, money	Serious, explicit, no compression

Core Principles

1. A Control Names Its Exact Action

Buttons start with a verb naming the specific thing that happens: Send, Save draft, Delete project. Never OK, Submit, Let's go!, or a bare Yes/No on anything consequential. A confirmation repeats the consequence so the dialog is answerable without reading the body: "Delete this project?" offers Delete project and Cancel.

2. Nothing Does Double Duty

A label labels, an example demonstrates, a hint hints. A placeholder is never the field's only label — it disappears exactly when the user needs it. Copy that restates the heading, the metric row, or the data just shown is deleted, not rewritten. If a summary line can't add a conclusion or a next action, drop it.

3. Errors Are Instructions, Placed Where It Broke

An error names what to do next, adjacent to the failing field, phrased positively, and shown before the mistake where possible.

Bad	Good
That password is too short	Choose a password with at least 8 characters
Invalid name	Use only letters for your name
Oops! Something went wrong.	Unable to save. Check your connection and try again.

No blame, no "oops", no exclamation marks, no "we" that obscures who failed or what to do. If the same error keeps firing, the fix is the interaction, not the wording — say so rather than polishing it.

4. Empty States Teach

An empty state says what this place is, how to fill it, and gives one clear next action. In a tool or CLI-adjacent surface, show the exact next command in a <code> block and add that everything else still works. Never a bare "No data". Search and filter empties name the query and offer the exit: "No results for 'quarterly'. Clear filters." Never park persistent, load-bearing information in an empty state — it vanishes the moment content arrives.

5. Settings Describe the ON State

Label a toggle for what happens when it is on — "Send read receipts" — and let users infer the off state. Never label the negative; it turns the toggle into a double negative. Link directly to a referenced setting instead of narrating the path to it.

6. Links Describe Their Destination

Link text must make sense read out of context, because screen-reader users navigate by a list of links: "Read the billing docs", never "Click here" (which also assumes a mouse), and never several bare "Learn more" links on one page — suffix each one.

7. When a Sentence Names an Entity, Link the Entity

Verdicts, tooltips, summaries, and empty states are navigation, not decoration. If the copy says "3 projects hire this job", each is reachable from those words.

8. Write for Translation from the First String

Every user-facing string exists in every supported locale from the first commit, in one string table, with a key-parity check. Never build a sentence by concatenating fragments around a variable ("You have " + n + " new messages") — word order and plural rules differ per language; use full templated strings with proper pluralization. No idioms, no wordplay, no humor that won't survive translation. Translate chrome only: verbatim quotes and captured data stay in the language they were captured in, because translating a quote destroys the thing that made it evidence.

9. Address the Reader Directly

"You", not "the user". Skip unnecessary gender. Match the input device — "tap" on touch, "click" with a pointer, "select" when both are possible. Use possessives sparingly ("Favorites" over "Your Favorites") and never switch perspective mid-flow.

10. One Vocabulary, One Capitalization Policy

If it's "Archive" in the menu, it is not "Move to storage" in the toast. A multi-step flow picks one word for advancing and keeps it. Pick title case or sentence case per element type and apply it consistently; sentence case is the safer default — calmer, no per-word rules, localizes cleanly.

11. No Selling Inside the Product

Interface copy is not marketing copy. Delete adjectives that sell ("powerful", "seamless", "delightful", "effortless"), superlatives, and enthusiasm the user did not ask for. The transformation claims belong on the landing page, where before-after owns them. Inside the product, describe.

12. Jargon Needs Evidence

Borrowed from jtbd's kill switch, applied to user-facing strings: every term of art in the copy must be one the user already uses (name the quote), one the interface teaches on first use, or gone. When you cannot point to a quote or a teaching moment, replace it with the plain word.

Common Mistakes

Mistake	Fix
Copy written before reading the corpus	Read jtbd.json; let the anxiety force shape the confirmation
Invented vocabulary where the corpus has a real word	Take the noun from evidence.quotes[] and cite the id
OK / Yes confirming a destructive action	Repeat the consequence: Delete project
Submit on a form	Name what it does: Create account, Send request
"Oops! Something went wrong."	Say what to do, next to the field that failed
"We're having trouble…"	Direct status and next step: "Unable to load content"
Error that only fires because the interaction is wrong	Report the interaction as the defect; don't reword it
"No data." as the whole empty state	Orient, show the exact next action, note what still works
Placeholder doing the label's job	Visible label; placeholder shows the format
"Don't send read receipts" toggle	Label the ON state
"Click here" / three bare "Learn more" links	Describe each destination
"Continue" on step 2, "Next" on step 3	One flow vocabulary throughout
"Save Changes" beside "Discard changes"	One capitalization policy per element type
"You have " + n + " messages"	Full templated string with pluralization
A locale added "later"	Key parity from the first commit
Quote translated along with the chrome	Chrome translates; captured evidence does not
"Powerful", "seamless", "effortless" in a settings screen	Delete the adjective; describe the behavior
Summary line restating the metrics above it	Add a conclusion or delete the line
Entity named in prose but not linked	Link it to its detail view

Step 2 — Test it on someone who has read none of this

Copy that survives its author is not the same as copy that survives a stranger. When the strings matter — a hero, an onboarding sequence, a destructive confirmation, a pricing page — hand the artifact to respondent-panel verbatim, with no rationale attached, and treat convergent misreadings as defects in the copy rather than in the readers.

Then revise against the convergent findings only, and re-run the same panel briefs so the comparison is clean. Divergence along an axis (newcomers fine, burned-before users suspicious) is a targeting decision, not a rewrite mandate.

Review Output Format

Use this format when reviewing existing copy rather than writing new copy. If an orchestrator is running this skill as one domain of a larger review, hand it the findings and let its format, severity scale, consolidation, cap, and verdict take precedence over this section.

Findings

One table, ordered by severity, then by reach:

Severity	Location	Before	After	Why
HIGH	src/DeleteDialog.tsx:29	"OK"	"Delete project"	A consequential action must repeat its consequence
MEDIUM	src/PasswordField.tsx:36	"Invalid password"	"Choose a password with at least 8 characters"	The error must say how to fix it

• Severity — HIGH misleads, hides a consequence, or blocks recovery; MEDIUM makes a task harder to understand; LOW is isolated voice or consistency polish.
• Location — cite path/to/file:line, or the exact screen and element when there is no source. Quote the current string exactly, typos included.
• Why — name the violated principle and the comprehension or trust cost.

One root cause is one row; list every affected location in it. Never pad the table: a short review is a valid result. Cap at 15 findings and say what you left out.

Considered but Rejected

Two to five candidates you inspected and deliberately did not report, with the reason — the established voice permits it, the evidence is insufficient, the convention is intentional, or the change adds churn without user benefit. These must be real candidates, not invented filler.

Verification

What you actually checked: the flow walked, the variable interpolation and pluralization exercised, the locales compared for key parity, the narrow-width wrapping observed, the panel run. Anything you could not check is listed as Not verified with what remains. A verification gap is never reported as a finding.

Verdict

Exactly one: Block (a HIGH remains), Needs changes (only MEDIUM/LOW remain), or Approve (no actionable findings and the claimed coverage was verified).
