The first pass used two-letter abbreviations (CC/CX/GC/OH) in brand-coloured rounded squares to identify each harness on the Alternative Agents scatter. Letters worked but looked cheap.
Replace the three CLI harnesses (Claude Code, Codex CLI, Gemini CLI) with a generic terminal-prompt glyph — a chevron plus cursor, the near-universal visual shorthand for "this is a CLI tool" — and keep the per-harness brand-adjacent background colour as the actual discriminator between them. This mirrors how the evo-claw.com reference image distinguishes Gemini CLI and Codex CLI markers.
For the OpenHands harness, draw a simple five-finger hand silhouette (five vertical finger strokes plus a rounded palm) in the existing OpenHands yellow. It's geometric primitives — lines and one quadratic path — not a derivative of any trademarked logo, and is unambiguously a hand at marker size.
All four files keep the same 80x80 viewBox and filename, so no code change is needed — leaderboard_transformer.py's composite marker path picks them up automatically.
