Guidelines for writing UI code in Warp's GUI desktop client, centered on reusing shared components and themes instead of adding one-off styling.

  • Starting any UI change in the Warp desktop client codebase
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Styling a new button in Warp and choosing which shared theme to use
  • Reviewing a Warp UI pull request for reinvented components or design-system drift

What it does

This is a growing catalog of rules for the UI code of Warp's desktop client, which is built on the WarpUI pixel and GPU framework in the `app/` crate. The agent reads the list once at the start of any UI task and keeps the relevant rules in mind while implementing. Each rule records a lesson reviewers kept having to repeat, such as reinventing a component or bypassing a shared abstraction.

The guideline visible here covers button colors: pick one of the existing shared themes, such as `PrimaryTheme`, `SecondaryTheme`, `NakedTheme` or `DangerPrimaryTheme`, and use it unchanged rather than inventing colors. The skill applies only to the GUI front-end. The headless TUI front-end has its own skills, and a separate skill covers the settings modal.

When your agent uses it

  • Starting any UI change in the Warp desktop client codebase
  • Styling a new button in Warp and choosing which shared theme to use
  • Reviewing a Warp UI pull request for reinvented components or design-system drift

Example prompts

  • “Add a Retry button to the update banner in the Warp client, following the UI guidelines.”
  • “Check my new dialog against Warp's GUI guidelines before I open the PR.”
  • “Which button theme should a destructive Delete action use in the Warp app UI.”

Requirements

  • A checkout of the Warp repository

What it can do on your machine

Read from SKILL.md and the folder at commit f571865. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Warp GUI UI Guidelines loads about 947 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 495 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~947

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
GUI desktop app only. Catalog of guidelines for writing UI code in the Warp client. Read whenever doing any UI work in this repo, up front before writing the change, so the relevant guidelines shape the implementation.

gui-ui-guidelines

Scope — GUI desktop app only. This skill applies to Warp's GUI desktop front-end (the app/ crate on the WarpUI pixel/GPU framework). It does not apply to the headless TUI front-end (crates/warp_tui; cell-grid TuiElement library under crates/warpui_core/src/elements/tui), which has its own components, tests, and change-verification workflow. For TUI work, see the tui-ui-guidelines, tui-testing, and tui-verify-change skills instead.

This skill is a growing catalog of guidelines for working on Warp's UI code. Each guideline captures a lesson that would otherwise be re-learned through review — typically because an agent or contributor reinvented a component, drifted from the design system, or bypassed a shared abstraction.

How to use this skill:

  • Read through the guidelines below once at the start of any UI task, then keep them in mind while implementing. The list is short enough to scan.
  • Each guideline is self-contained. Not every one will apply to every task — use judgment. But if a guideline does apply, follow it.
  • When in doubt, prefer reusing an existing abstraction over introducing a new one. The Warp UI has accumulated a well-factored set of shared components and themes; new one-offs almost always drift.

For work on the settings modal (app/src/settings_view/) — a settings page, a SettingsWidget, or anything that affects settings search — also read the gui-settings-ui skill, which covers the page-title, widget-gating, and widget-splitting rules specific to that surface.

New guidelines get added here over time. If you discover a recurring UI mistake that would have been caught by a written rule, add it.

Guideline: Reuse button themes

Button colors come from a shared set of ActionButtonTheme impls in app/src/view_components/action_button.rs (and the parallel Theme impls in crates/ui_components/src/button/themes.rs) — PrimaryTheme, SecondaryTheme, NakedTheme, DangerPrimaryTheme, etc. These encode the design system and keep button colors consistent across the app.

When styling a button, use one of the existing themes unchanged. The shared themes are well-established and vetted; if one looks "wrong" for your use case, the most likely explanation is that you're reaching for the wrong theme, not that the theme is buggy.

Do not modify a shared theme on your own initiative. Changing PrimaryTheme, SecondaryTheme, etc. affects every button in the app, and a tweak that fixes your screen can silently regress others. Only edit a shared theme when the user has explicitly confirmed that the design-system component itself needs to change.

Red flags that you're about to make buttons inconsistent:

  • Writing a new impl ActionButtonTheme for FooPrimaryTheme that delegates to PrimaryTheme and only tweaks one method (usually text_color). Almost always the right move is to use PrimaryTheme directly and accept the result.
  • Hard-coding ColorU::new(...) instead of using appearance.theme() accessors (accent, font_color(bg), foreground, etc.).
  • Setting should_opt_out_of_contrast_adjustment to true to force a specific label color.
  • Naming a theme after a feature or view (FooPrimaryTheme, BarSubmitTheme) rather than a design-system role.

If an existing theme genuinely doesn't fit and you think the shared theme should change, surface that to the user before editing it, rather than either editing it unilaterally or papering over it with a one-off.
