Visual kits for agents that need to design well
Pick what you're building, preview every kit on that surface, and hand your agent a complete visual system — fonts, colors, tokens, and component rules.
Pick what you're building, preview every kit on that surface, and hand your agent a complete visual system — fonts, colors, tokens, and component rules.
A high-energy kit operating on exactly two surfaces, near-black (#1a1a1a) and acid-green (#1bff59), as the only valid backgrounds; no whites or neutrals anywhere. Barlow Condensed headings scale to poster dimensions, sometimes rotated 90° to fill the full container height. Space Mono is the universal face for body copy, labels, navigation, and metadata. Pill-shaped CTA buttons render in the inverse surface color, and a visible surface-toggle switches the entire UI between the two colors.

Acid Signal
Every kit is judged per use case against concrete criteria — chart-series distinctness, text contrast, information density — not keyword matching.

# Machine-readable tokens (the WHAT). The prose body gives the WHY + the rules.
# contract is THIS DOCUMENT'S shape and has nothing to do with the kit's
# revision below. It moves when a section is added, renamed or removed; a kit
# that never changed can arrive under a new one, and a kit that changed every
# token arrives under the same one. Read them independently.
#
# FIRST key on purpose. `name` is caller-supplied and yamlQuote escapes only the
# double quote, so a crafted kit name can inject lines into this block — every
# reader of this front matter honours the FIRST occurrence of a key, which puts
# an injected duplicate too late to matter.
contract: "1.0"
kit:
# The id is the durable handle; name and slug are both mutable.
# version is this record's monotonic revision: 0 = never versioned,
# null = the server did not report one. Diff against it; don't hash the file.

background: "#1A1A1A"Three ways from the same kit: run "npx identityforge@latest apply acid-signal-black" with the CLI to write the tokens and DESIGN.md into your project, fetch it through the Identity Forge MCP server inside Claude Code, Cursor, or OpenCode, or install from the shadcn registry at /r/acid-signal-black.json with "npx shadcn add".
A complete brand system: a font pairing, 28 semantic color tokens in light and dark, a typography scale, spacing and elevation, per-element treatments, distinctive motifs, do's and don'ts, and a DESIGN.md a coding agent builds from. Exports cover shadcn registry items, Tailwind v3 and v4 themes, DTCG tokens JSON, and plain CSS variables.
Acid Signal Black is free: its full color tokens, fonts, DESIGN.md, and every export are available at no cost.
