jetbrains-ui

jetbrains-ui is a skill for Claude Code, Codex from Kilo-Org/kilocode. It costs 60 tokens per session (6,405 once invoked), scanned A, original, MIT.

A set of instructions for building and reviewing the Swing-based user interface of a JetBrains plugin. Swing and IntelliJ Platform components are Java UI building blocks used to make plugin panels, dialogs, settings pages, and notifications.

In plain words
What is it for?
It helps create or review layouts, tool windows, popups, settings pages, themes, colors, fonts, borders, and other JetBrains plugin screens.
Why use it?
It reduces inconsistent UI and prevents use of technologies that this plugin does not support, such as Compose, JCEF, or the Kotlin UI DSL.

About the project

Kilo Code is an open-source AI coding agent that works inside VS Code and JetBrains, from the command line, or through cloud services. Developers use it to build software with AI models, switch between providers, and run cloud agents or automated code reviews. The catalogue includes eleven skills, eight agents, and one instruction for Kilo Code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

jetbrains-ui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

JetBrains Plugin UI Guidelines

Detailed UI reference for packages/kilo-jetbrains/. See packages/kilo-jetbrains/AGENTS.md for the hard restrictions (no Compose/DSL/JCEF) and the reuse-first index; this skill covers the how.

Technology Choices

Do not use Kotlin UI DSL v2 (com.intellij.ui.dsl.builder) in this plugin. Use standard Swing with IntelliJ Platform components for all UI layout. The JetBrains modular template and some older sections of the codebase reference the DSL, but Kilo should not introduce it.

Do not use Kotlin Compose or intellij.platform.compose in this plugin. The JetBrains modular template uses Compose for its demo tool window, but Kilo should use standard Swing with IntelliJ Platform components only. Keep all plugin UI in the existing Swing-based stack.

Do not use JCEF (JBCefBrowser) in this plugin. JCEF does not work in JetBrains remote development (split mode): the frontend process runs on the client machine but JCEF requires a display on the host, making it effectively unusable for remote users. Use standard Swing with IntelliJ Platform components for all UI.

Need API
Any layout, forms, panels Standard Swing with IntelliJ Platform component replacements
Tool windows SimpleToolWindowPanel + ToolWindow.contentManager
Menus and toolbars Action System
Dialogs Extend DialogWrapper

Style Tokens

UiStyle (frontend/src/main/kotlin/ai/kilocode/client/ui/UiStyle.kt) is the single source of truth for reusable UI constants in this plugin.

Before introducing any new reusable color, spacing value, border, size, font, or helper:

  1. Check the IntelliJ source ($INTELLIJ_REPO) or public repository for an existing standard API or named key (e.g. JBUI.CurrentTheme.*, UIUtil.*, NamedColorUtil.*, JBColor.namedColor(...), JBFont.*).
  2. If a standard platform key exists, use it directly — do not copy the value into UiStyle.
  3. If no standard key fits, add the new reusable token to UiStyle. Do not scatter constants into component-local fields, pass them through constructors, or duplicate them across files.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
