brand-guidelines · getsentry — Claude Code skill: what it does, how to install
Applies Sentry brand and copy guidelines to user-facing text, error states, and UI flows. Useful when writing UI labels, empty states, or docs.
npx skills add getsentry/skills --skill brand-guidelines -a claude-codeWhat brand-guidelines does
The skill instructs your coding assistant to write copy according to Sentry style guides. By default, it enforces Plain Speech: concise, direct copy using active verbs without filler words or technical jargon. Button labels are capped at two to three words, and robotic passive structures get stripped out automatically.
When working on empty states, 404 pages, or onboarding, the skill switches to Sentry Voice. This tone introduces empathetic, self-aware humor aimed at software glitches rather than the user. The skill strictly bans playful voice in billing flows, error dialogs, and settings where clarity is essential.
It also enforces American English spelling, Title Case for headers, sentence case for buttons, and strict punctuation rules such as omitting exclamation marks and ending periods in buttons.
What it helps with
- Write direct action-oriented labels for buttons and dialogs
- Format clear error messages that explain the issue and the next step
- Craft empathetic empty states and 404 pages using Sentry Voice
- Remove robotic phrasing and passive voice from product UI
Example prompts for the agent
- Write an empty state message for an empty issue stream using Sentry guidelines
- Rewrite this error dialog copy using Plain Speech rules
- Generate button labels and confirmation text for a project deletion modal

What does the brand-guidelines skill do?
It guides the agent when generating interface copy, documentation, and product announcements. It divides tone between functional Plain Speech and personality-driven Sentry Voice.
Where does the skill prohibit using Sentry Voice?
Sentry Voice is barred from error messages, settings, documentation, and billing screens. In those areas, the skill forces Plain Speech so users stay focused and retain trust.

# Brand Guidelines
Write user-facing copy following Sentry's brand guidelines.
## Tone Selection
Choose the appropriate tone based on context:
| Use Plain Speech | Use Sentry Voice |
|------------------|------------------|
| Product UI (buttons, labels, forms) | 404 pages |
| Documentation | Empty states |
| Error messages | Onboarding flows |
| Settings pages | Loading states |
| Transactional emails | "What's New" announcements |
| Help text | Marketing copy |
**Default to Plain Speech** unless the context specifically calls for personality.
## Plain Speech (Default)
Plain Speech is clear, direct, and functional. Use it for most UI elements.
### Rules
1. **Be concise** - Use the fewest words needed
2. **Be direct** - Tell users what to do, not what they can do
3. **Use active voice** - "Save your changes" not "Your changes will be saved"
4. **Avoid jargon** - Use simple words users understand
5. **Be specific** - "3 errors found" not "Some errors found"
### Examples
| Instead of | Write |
|------------|-------|
| "Click here to save your changes" | "Save" |
| "You can filter results by date" | "Filter by date" |
| "An error has occurred" | "Something went wrong" |
| "Please enter a valid email address" | "Enter a valid email" |
| "Are you sure you want to delete?" | "Delete this item?" |
## Sentry Voice
Sentry Voice adds personality in appropriate moments. It's empathetic, self-aware, and occasionally snarky.
### Principles
1. **Empathetic snark** - Direct frustration at the situation, never the user
2. **Self-aware** - Acknowledge the absurdity of software
3. **Fun but functional** - Personality should enhance, not obscure meaning
4. **Earned moments** - Only use when users have time to appreciate it
### Examples
**404 Pages:**
> "This page doesn't exist. Maybe it never did. Maybe it was a dream. Either way, let's get you back on track."
**Empty States:**
> "No errors yet. Enjoy this moment of peace while it lasts."
**Onboarding:**
> "Let's get your first error. Don't worry, it's not as scary as it sounds."
**Loading States:**
> "Crunching the numbers..."
> "Fetching your data..."
### When NOT to Use Sentry Voice
- Error messages (users are frustrated)
- Settings pages (users are focused)
- Documentation (users need information)
- Billing/payment flows (users need trust)
## General Rules
### Spelling and Grammar
- Use **American English** spelling (color, not colour)
- Use **Title Case** for headings and page titles
- Use **Sentence case** for body text, buttons, and labels
### Punctuation
- **No exclamation marks** in UI text (exception: celebratory moments)
- **No periods** in short UI labels or button text
- **Use periods** in complete sentences and help text
- **No ALL CAPS** except for acronyms (API, SDK, URL)
### Word Choices
| Avoid | Prefer |
|-------|--------|
| Please | (omit) |
| Sorry | (be specific about the problem) |
| Error occurred | Something went wrong |
| Invalid | (explain what's wrong) |
| Success! | (describe what happened) |
| Oops | (be specific) |
## Dash Usage
| Type | Use | Example |
|------|-----|---------|
| Hyphen (-) | Compound words, ranges | "real-time", "1-10" |
| En-dash (--) | Ranges, relationships | "2023--2024", "parent--child" |
| Em-dash (---) | Interruption, emphasis | "Errors---even small ones---matter" |
In most UI contexts, use hyphens. Reserve en-dashes for date ranges and em-dashes for longer prose.
## UI Element Guidelines
### Buttons
- Use action verbs: "Save", "Delete", "Create"
- Be specific: "Create Project" not just "Create"
- Max 2-3 words when possible
- No periods or exclamation marks
### Error Messages
1. Say what happened
2. Say why (if helpful)
3. Say what to do next
**Good:** "Could not save changes. Check your connection and try again."
**Bad:** "Error: Save failed."
### Empty States
1. Explain what would normally be here
2. Provide a clear action to populate the state
3. Sentry Voice is appropriate here
**Good:** "No projects yet. Create your first project to start tracking errors."
### Confirmation Dialogs
- Make the action clear in the title
- Explain consequences if destructive
- Use specific button labels ("Delete Project", not "OK")
### Tooltips and Help Text
- Keep under 2 sentences
- Explain the "why", not just the "what"
- Link to docs for complex topics
## Anti-Patterns
Avoid these common mistakes:
- **Robot speak:** "Item has been successfully deleted" -> "Deleted"
- **Passive voice:** "Changes were saved" -> "Changes saved"
- **Unnecessary words:** "In order to" -> "To"
- **Hedging:** "This might cause..." -> "This will cause..."
- **Double negatives:** "Not unlike..." -> "Similar to..."
- **Marketing speak in UI:** "Supercharge your workflow" -> "Speed up your workflow"
