claude-kbo-theme

KBO (Korean Baseball Organization) team theme for Claude Code — dress up Clawd (Claude's mascot) with your favorite team's colors, cap, and logo.

What it does

Patches the Clawd character in your Claude Code binary with:

• Team color — body dyed in your team's official color
• Baseball cap — sitting on top of Clawd's head, with team logo in pixel art
• Eye color — adjusted for visibility on dark team bodies

All 10 KBO teams supported.

How it works

On install, the tool:

1. Finds your Claude Code binary (~/.local/bin/claude or /usr/local/bin/claude)
2. Extracts the embedded JavaScript from the Mach-O __BUN.__bun section
3. Patches the Clawd rendering code (color strings, hat insertion)
4. Rebuilds the Bun blob with correct offsets and trailer
5. Extends the Mach-O segment with page-aligned growth (16KB on ARM64)
6. Re-signs the binary with an ad-hoc signature (codesign -s -)

The entire binary manipulation is implemented in pure Node.js (~500 lines, no external dependencies) — no node-lief, no tweakcc, no shell wizardry.

The original binary is backed up to <binary>.backup on first run.

Platform support

• ✅ macOS (ARM64 and x86_64) — Claude Code native binary
• ⚠️ Linux — not tested (ELF binaries have a different format)
• ❌ Windows — not supported

Limitations

• Claude Code updates overwrite the patched binary. Just run claude-kbo <team> again after updates.
• The backup is created from whatever was present on first run, so if Claude Code was already modified, run --restore before updating.
• Terminal alignment of the cap is pixel-perfect only for monospace fonts rendering block-drawing characters correctly.
