pi-echo-themes

The echo-signal theme pair (dark/light) plus a matching welcome header.

Visual preview: see ../../docs/echo-signal-preview.png (also shown in the root README.md) — a mocked real session showing both variants with actual theme tokens applied (not an approximation), plus the welcome-header mockup.

Design note

The teal "signal" accent and the rest of the palette are a deliberate design, not a random pick — see the preview link for the reasoning (high-contrast tool-state boxes, diff colors that don't clash with syntax highlighting, a light variant that's actually redesigned for a light background rather than a naive inversion of the dark one). The one standout idea: the six required thinking* border tokens (thinkingOff → thinkingXhigh, plus optional thinkingMax) are treated as a real gradient — cool and quiet at off, warming steadily, landing hot at max — so Pi's reasoning-effort level reads from the editor border color alone.

The welcome header (ctx.ui.setHeader(), same primitive as Pi's own official custom-header.ts example) deliberately does not hardcode echo-signal's hex values — it uses theme.fg() with the seven thinking-level tokens and the accent token, which every Pi theme defines. That means the header looks coherent regardless of which theme is actually active, not just when echo-signal is selected. Its status line lists real, currently-registered echo-* slash commands (via pi.getCommands()) rather than a package count — some echo packages (like pi-echo-hooks) register no tools or commands at all, so a package count isn't reliably computable from Pi's extension API; a command list is the honest equivalent, not a downgrade.

Usage

pi install ./packages/pi-echo-themes -l
/settings          # select "echo-signal-dark" or "echo-signal-light"
/builtin-header    # restore Pi's default header if you'd rather keep the theme without the custom welcome screen
