The core thesis: <strong>interface text is\nfunctional infrastructure, not decoration — a user reads it under task\npressure, often in a second language, often through a screen reader, and every\nword either moves them forward or costs them a support ticket.</strong></p>\n<p>Boundaries: this skill owns the <em>language</em>. The UX <em>patterns</em> the language\nlives in (when to show an empty state, validation timing, dialog escalation)\nare <code>sota-frontend-design</code> rules/04; technical documentation is\n<code>sota-docs-workflow</code>; outward-facing marketing content is <code>sota-copywriting</code>;\nCLI-specific output contracts are <code>sota-cli-ux</code>.</p>\n<h2>BUILD mode</h2>\n<p>When writing or changing interface text:</p>\n<ol>\n<li><strong>Write the unhappy paths first</strong> — errors, empty states, and confirmations\ncarry more consequence than the happy path (<code>rules/03</code>).</li>\n<li><strong>Apply the plain-language spine</strong> to every string: relevant, findable,\nunderstandable, actionable (ISO 24495-1) — front-load the point, one idea\nper sentence, common words (<code>rules/01</code>).</li>\n<li><strong>Name things once.</strong> Check the product glossary before introducing a term;\nnever let the UI, docs, and API call the same concept different names\n(<code>rules/01</code> §4).</li>\n<li><strong>Buttons are verbs with objects</strong> (\"Delete project\", never \"OK\"/\"Yes\"),\nand every dialog states the specific consequence (<code>rules/02</code>).</li>\n<li><strong>Write for the translator and the screen reader as you go</strong>: externalized\nstrings, ICU plurals, named placeholders, descriptive link text, accessible\nnames matching visible labels (<code>rules/04</code>).</li>\n<li>Before finishing, run each loaded rules file's <strong>Audit checklist</strong> against\nthe diff — including the greps for banned strings.</li>\n</ol>\n<h2>AUDIT mode</h2>\n<p>When reviewing existing product copy:</p>\n<ol>\n<li>Inventory the string surface: localization files (<code>*.json</code>, <code>*.po</code>,\n<code>*.strings</code>, <code>*.xlf</code>), hardcoded literals in components, error-message\nconstants, email/notification templates.</li>\n<li>Run the banned-pattern greps from each rules file's audit checklist\n(e.g. <code>\"click here\"</code>, <code>\"an error occurred\"</code>, <code>\"invalid input\"</code>,\nconcatenated plurals).</li>\n<li>Walk the critical flows as a user: signup, first-run empty state, a failed\npayment/submit, a destructive action. Judge every string against\n<code>rules/01</code>–<code>03</code>.</li>\n<li>Check localization readiness (<code>rules/04</code>) even for single-language\nproducts — retrofitting string externalization is expensive.</li>\n</ol>\n<h3>Severity conventions</h3>\n<ul>\n<li><strong>Critical</strong> — copy that causes data loss or deception: destructive-action\ndialog whose buttons don't name the action; error message leaking secrets,\ninternals, or account existence; consent text that misrepresents what\nhappens; dark-pattern confirmshaming.</li>\n<li><strong>High</strong> — copy that blocks task completion or excludes users: error with no\nnext step; placeholder used as the only label; icon-only control with no\naccessible name; untranslatable concatenated strings; link text meaningless\nout of context (\"click here\").</li>\n<li><strong>Medium</strong> — friction and inconsistency: same concept under two names;\njargon or internal codenames in UI; blame-framed errors; toasts carrying the\nonly path to an action; missing empty-state guidance.</li>\n<li><strong>Low</strong> — polish: tone drift, capitalization inconsistency, \"please\"\ninflation, exclamation marks, filler words (\"simply\", \"just\").</li>\n</ul>\n<h3>Finding format</h3>\n<p><code>file:line | rule violated | severity | effort | fix</code> — quote the current\nstring and propose the exact replacement string; copy findings without a\nproposed rewrite are half-findings.</p>\n<h2>Rules index</h2>\n<table>\n<thead>\n<tr>\n<th>File</th>\n<th>Read this when...</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td><code>rules/01-voice-tone-plain-language.md</code></td>\n<td>Establishing or auditing the overall language system: voice vs tone, stress-aware tone shifts, plain-language rules (ISO 24495-1), readability, terminology/glossary discipline, capitalization and punctuation conventions.</td>\n</tr>\n<tr>\n<td><code>rules/02-microcopy-components.md</code></td>\n<td>Writing the words in components: buttons/CTAs, labels vs placeholders vs hints, empty states, onboarding and tooltips, confirmation dialogs, notifications/toasts/badges, counts and plurals, relative time, link text, loading/progress text.</td>\n</tr>\n<tr>\n<td><code>rules/03-errors-feedback.md</code></td>\n<td>Anything that reports a problem or outcome: error-message anatomy, no-blame framing, validation wording, security-sensitive errors, warnings vs errors, success confirmations, permission prompts, and dark-pattern-free upsell moments.</td>\n</tr>\n<tr>\n<td><code>rules/04-accessibility-localization.md</code></td>\n<td>Making the language reach everyone: WCAG 2.2 language criteria, alt text craft, accessible names, screen-reader-facing strings, string externalization, ICU plurals, translator context, text expansion, RTL, inclusive language.</td>\n</tr>\n</tbody>\n</table>\n<h2>Top-10 non-negotiables</h2>\n<ol>\n<li><strong>Every error says what happened and what to do next</strong> — a dead-end error\nis a support ticket with extra steps.

(rules/03 §2)</li>\n<li><strong>One concept, one name</strong>, everywhere — UI, docs, API, support. Maintain a\nglossary; renames are migrations, not edits. (rules/01 §4)</li>\n<li><strong>Placeholders are never labels</strong>; hint text never disappears while the\nuser still needs it. (rules/02 §2)</li>\n<li><strong>No copy relies on color, position, or an icon alone</strong> to carry meaning;\nevery control has an accessible name matching its visible label.\n(rules/04 §2)</li>\n<li><strong>Link and button text stands alone</strong>: \"View invoice #1042\", never\n\"click here\" or a bare \"Learn more\". (rules/02 §8)</li>\n<li><strong>No string concatenation, ever</strong> — ICU MessageFormat with named\nplaceholders and real plural rules; \"1 items\" ships nowhere. (rules/04 §4)</li>\n<li><strong>Front-load every string</strong>: the first three words carry the point;\nscanning users read little else. (rules/01 §2)</li>\n<li><strong>Security-sensitive copy never leaks</strong>: auth errors don't confirm account\nexistence, error surfaces never show stack traces, internals, or secrets\n— cross-check <code>sota-code-security</code> rules/02 and /07.
