Bitwarden's product content style guide for end-user-facing GUI copy — voice, tone, AP-style-with-exceptions grammar, sentence case in UI, and accessibility-first language at a U.S. 7th-grade reading level.

This skill grounds GUI copy decisions in Bitwarden's product content style guide. Apply it to
end-user-facing strings only — button labels, error messages, toasts, modals, onboarding flows,
empty states, form labels, helper text, link text, and similar. Do not apply to design tokens,
code comments, internal/dev-facing strings, or marketing copy.
When in doubt about a specific case, ask before changing copy.
Voice is constant. Tone flexes with context.
Product voice is approachable, encouraging, and transparent — consistent across platforms.
Tone conveys mood and depends on who you're talking to and what's happening. Security is serious
stuff. Users aren't looking for humor or fluff — they want to know their information is safe. So
Bitwarden's product tone is almost always serious and respectful.
Tone spectrums:
Where common content types land on the tone map (axes: casual ↔ formal × matter-of-fact ↔ enthusiastic):
| Content type | Casual / Formal | Matter-of-fact / Enthusiastic |
| ---------------- | ----------------- | ----------------------------- |
| Success messages | Casual | Enthusiastic |
| Onboarding copy | Casual | Enthusiastic |
| Dialogs | Casual | Matter-of-fact |
| Empty states | Casual | Matter-of-fact (slightly) |
| Labels | Neutral | Matter-of-fact |
| Community | Formal | Enthusiastic |
| Confirmations | Formal | Matter-of-fact |
| Help articles | Formal (slightly) | Neutral |
| Warnings | Formal | Matter-of-fact |
| Error states | Formal | Matter-of-fact |
Error message — formal, matter-of-fact:
Onboarding message — casual, enthusiastic:
During explicit copy critique ("review this copy", "is this error message ok"):

references/accessibility-rules.md.Inside figma-to-angular runs (external skill in the clients repo, not bundled here):
When the Figma design includes copy strings, validate them against this guide before emitting
them into the Angular template. If a string clearly violates a rule (e.g., title-case button,
ampersand, "Click here" link), surface the issue and propose a compliant alternative — do not
silently rewrite. Ask the user which to use.
Inside design-review critiques:
If the stage is 60% or 90%, include content observations alongside visual feedback (90% is the
right stage for "nitty-gritty grammar, finalizing copy"). Skip content nitpicks at 30% — the
copy will change. Frame content feedback the same way as visual feedback: tied to user/product
goals, not personal taste.

the references file if the rule lives there).
Keep critique specific. "The button uses title case; sentence case per
references/grammar-mechanics.md (Capitalization)" beats "the capitalization is off."
The detailed rules live in two references files. Load them when the critique needs them — most
copy issues touch only one or two rules.
references/grammar-mechanics.md — Acronyms, ampersands, capitalization (sentence case,product names, features, lowercase objects), dates and months, days of the week, e.g. / i.e.,
ellipsis, file sizes and formats, money, numbers, Oxford comma, times and time zones, versus.
references/accessibility-rules.md — Reading level and directness, scannable layouts,non-English and ESL considerations, spelling out acronyms, avoiding "easy" and "simple"
framings, text styling, spatial language, alt text, meaningful link text, gender-neutral
pronouns.
Generate breadboard circuit mockups and visual diagrams using HTML5 Canvas drawing techniques. Use when asked to create circuit layouts, visualize electronic component placements, draw breadboard diagrams, mockup 6502 builds, generate retro computer schematics, or design vintage electronics projects. Supports 555 timers, W65C02S microprocessors, 28C256 EEPROMs, W65C22 VIA chips, 7400-series logic gates, LEDs, resistors, capacitors, switches, buttons, crystals, and wires.
> Use when a HyperFrames composition needs seek-safe 2D/3D keyframes, GSAP timelines, CSS keyframes, Anime.js, WAAPI, FLIP, paths, masks, SVG morph/draw, text trails, 3D depth, or `hyperframes keyframes` diagnostics. Don't use for broad scene strategy, brand design, media sourcing, captions, or general video planning.
Analyze images, websites, and Figma files to extract their design and generate a `design.md` with token system, component inventory, and reconstruction notes. Use this skill whenever the user wants to understand, document, replicate, or audit the design of something visual: a screenshot, a URL, a Figma link, a Pinterest reference, a mockup, a competitor's site, a component, a dashboard, a landing page. Also when they ask 'extract the design system from X', 'document the style of Y', 'analyze this visually', 'convert this image into tokens', 'help me replicate this design', 'what palette does this site use', 'how is this built'. Also for single elements: 'copy this navbar', 'recreate this illustration', 'give me a prompt to regenerate this graphic' — element mode outputs a focused element.md, with token-grounded image-model prompts when the element is visual art. If the user brings any visual source and wants to understand it at a design level — this skill should activate.
Premium brand-kit image generation skill for creating high-end brand-guidelines boards, logo systems, identity decks, and visual-world presentations. Trained for minimalist, cinematic, editorial, dark-tech, luxury, cultural, security, gaming, developer-tool, and consumer-app brand systems. Optimized for intentional logo concepting, refined composition, sparse typography, strong symbolic meaning, premium mockups, art-directed imagery, and flexible grid layouts.
Elite mobile app image-generation skill for creating premium, app-native screen concepts and flows. Designed for iOS, Android, and cross-platform mobile products. Prioritizes clean hierarchy, comfortably readable text, strong multi-screen consistency, controlled color palettes, non-generic creative direction, textured surfaces, image-led composition, tasteful custom iconography, and clean phone mockup framing. By default, screens should be shown inside a subtle premium iPhone or similar phone mockup with a visible frame, while the main focus stays on the app content itself. This skill generates images only. It does not write code.
Optimize web performance: bundle size, images, caching, lazy loading, and overall page speed. Use when site is slow, reducing bundle size, fixing layout shifts, improving Time to Interactive, or optimizing for Lighthouse scores. Triggers on: web performance, bundle size, page speed, slow site, lazy loading. Do NOT use for Core Web Vitals-specific fixes (use core-web-vitals), running Lighthouse audits (use perf-lighthouse), or Astro-specific optimization (use perf-astro).
