ok, i manually removed almost all chalk uses, except for the thinking border shit. how can we solve this with our theme stuff? do we need additional design tokens?


	private getThinkingBorderColor(level: ThinkingLevel): (str: string) => string {
		// More thinking = more color (gray → dim colors → bright colors)

Looking at this, the thinking border colors are used to set `this.editor.borderColor` which expects a chalk-style function `(str: string) => string`. We have a few options:

1. **Add thinking level colors to the theme** - Add 5 new tokens like `thinkingOff`, `thinkingMinimal`, etc.
2. **Reuse existing tokens** - Map the thinking levels to existing theme colors
3. **Add a theme method** - Add `theme.getThinkingBorderColor(level)` that returns the function

I think option 2 is cleanest - we can map to existing semantic colors:
- `off` → `borderMuted` or `dim`
- `minimal` → `border`
- `low` → `accent`
- `medium` → `accent` (could be same)
- `high` → `accent` (brighter if possible, or same)

Actually, looking at CustomEditor, does it accept a theme color name or does it need a function? Let me check:

bash

grep -A 5 "borderColor" packages/coding-agent/src/tui/custom-editor.ts | head -20


(no output)


Command exited with code 1


import { Editor } from "@mariozechner/companion-tui";

	public onEscape?: () => void;
	public onCtrlC?: () => void;
	public onShiftTab?: () => void;
	public onCtrlP?: () => void;
	public onCtrlO?: () => void;

	handleInput(data: string): void {
		// Intercept Ctrl+O for tool output expansion
		if (data === "\x0f" && this.onCtrlO) {
			this.onCtrlO();

		if (data === "\x10" && this.onCtrlP) {
			this.onCtrlP();
			return;
		}

		// Intercept Shift+Tab for thinking level cycling
		if (data === "\x1b[Z" && this.onShiftTab) {
			this.onShiftTab();
			return;
		}

		// Intercept Escape key - but only if autocomplete is NOT active
		// (let parent handle escape for autocomplete cancellation)
		if (data === "\x1b" && this.onEscape && !this.isShowingAutocomplete()) {
			this.onEscape();
			return;
		}

		// Intercept Ctrl+C
		if (data === "\x03" && this.onCtrlC) {
			this.onCtrlC();
			return;
		}

		// Pass to parent for normal handling
		super.handleInput(data);
	}
}


Let me check the base Editor class to see what borderColor expects:

grep -n "borderColor" packages/tui/src/editor.ts | head -20


grep: packages/tui/src/editor.ts: No such file or directory


grep -n "borderColor" packages/tui/src/components/editor.ts | head -20


18:	borderColor: (str: string) => string;
32:	public borderColor: (str: string) => string;
54:		this.borderColor = theme.borderColor;
62:		const horizontal = this.borderColor("─");


Perfect! So `Editor.borderColor` expects a function `(str: string) => string`. We need to provide a function that applies the appropriate theme color.

**Best solution**: Add a helper method to the Theme class that returns a border color function based on thinking level. This keeps the theming logic centralized:


}

function hexToRgb(hex: string): { r: number; g: number; b: number } {
	const cleaned = hex.replace("#", "");
	if (cleaned.length !== 6) {
		throw new Error(`Invalid hex color: ${hex}`);
	}
	const r = parseInt(cleaned.substring(0, 2), 16);
	const g = parseInt(cleaned.substring(2, 4), 16);
	const b = parseInt(cleaned.substring(4, 6), 16);
	if (Number.isNaN(r) || Number.isNaN(g) || Number.isNaN(b)) {

	const gIndex = Math.round((g / 255) * 5);
	const bIndex = Math.round((b / 255) * 5);
	return 16 + 36 * rIndex + 6 * gIndex + bIndex;
}

function hexTo256(hex: string): number {
	const { r, g, b } = hexToRgb(hex);
	return rgbTo256(r, g, b);
}

function fgAnsi(color: string | number, mode: ColorMode): string {
	if (color === "") return "\x1b[39m";
	if (typeof color === "number") return `\x1b[38;5;${color}m`;
	if (color.startsWith("#")) {

		} else {
			const index = hexTo256(color);
			return `\x1b[38;5;${index}m`;
		}
	}
	throw new Error(`Invalid color value: ${color}`);
}

function bgAnsi(color: string | number, mode: ColorMode): string {

Now I'll add a method to get a border color function for thinking levels. We can map them to existing theme colors:

edit

	getColorMode(): ColorMode {
		return this.mode;
	}
}

	getColorMode(): ColorMode {
		return this.mode;
	}

	getThinkingBorderColor(level: "off" | "minimal" | "low" | "medium" | "high"): (str: string) => string {
		// Map thinking levels to theme colors
		// More thinking = more prominent color
		let color: ThemeColor;
		switch (level) {
			case "off":
				return (str: string) => this.fg("dim", str);
			case "minimal":
				return (str: string) => this.fg("borderMuted", str);
			case "low":
				return (str: string) => this.fg("border", str);
			case "medium":
				return (str: string) => this.fg("borderAccent", str);

				return (str: string) => this.fg("accent", str);
			default:

		}
	}
}

Great! It builds successfully. Now let's verify the theme change works by checking the implementation:

Done! Here's what I did to solve the thinking border color issue:

## Solution Summary

Added a **`getThinkingBorderColor()`** method to the `Theme` class that maps thinking levels to existing theme colors:

- `off` → `dim` (most subtle)
- `minimal` → `borderMuted`
- `low` → `border`
- `medium` → `borderAccent`
- `high` → `accent` (most prominent)

This method returns a function `(str: string) => string` that's compatible with `Editor.borderColor`, and it reuses existing theme tokens so no new design tokens were needed.

The thinking level progression now goes from subtle → prominent using the existing semantic border colors, which works nicely with both dark and light themes.


we need to fix the tui test sources. what's lakcing is the htemes for selectlist, editor, and makrdown. create default themes shared across all the tests using chalk

This needs more careful editing since Markdown has different signatures. Let me check the patterns:


		it("should render simple nested list", () => {
			const markdown = new Markdown(
				`- Item 1
  - Nested 1.1
  - Nested 1.2
- Item 2`,
				0,
				0,
			);

			const lines = markdown.render(80);

			// Check that we have content
			assert.ok(lines.length > 0);

			// Strip ANSI codes for checking
			const plainLines = lines.map((line) => line.replace(/\x1b\[[0-9;]*m/g, ""));

			// Check structure
			assert.ok(plainLines.some((line) => line.includes("- Item 1")));

... (241 more lines not shown. Use offset=28 to continue reading)


The pattern is `new Markdown(text, paddingX, paddingY)` - need to add two more params: `undefined` for defaultTextStyle, and `defaultMarkdownTheme` for theme. Let me do this systematically:

sed -i '' 's/new Markdown(\(.*\), 0, 0)/new Markdown(\1, 0, 0, undefined, defaultMarkdownTheme)/g' packages/tui/test/markdown.test.ts


sed -i '' 's/new Markdown(\(.*\), 1, 0, {$/new Markdown(\1, 1, 0, {/g' packages/tui/test/markdown.test.ts


Let me check the ones with custom styles:
