Themes, userMessageDisplay, tableFormat patches fail on CC 2.1.76+ and 2.1.81

[ernaneluis]

Environment

• tweakcc version: 4.0.11
• Claude Code versions tested: 2.1.76 (npm), 2.1.81 (native binary)
• OS: macOS (Darwin 24.6.0)
• Node: v23.10.0 (nvm)

Failing patches

Patch	Error
themes	failed to find objArrMatch
userMessageDisplay	failed to find user message display pattern / failed to find Text component
tableFormat	fails silently (not listed in output)
patchesAppliedIndication	failed to find Claude Code version pattern (patch 2 failed)
agentsMd	failed to find early return null for injection / failed to find fs expression in function
sessionMemory	failed to find past sessions gate

Steps to reproduce

1. Install Claude Code 2.1.76 via npm or 2.1.81 native binary
2. Configure themes, userMessageDisplay, and tableFormat in ~/.tweakcc/config.json
3. Run npx tweakcc --apply

Expected behavior

Patches should apply successfully, enabling custom themes, user message styling, and table format changes.

Actual behavior

The patches fail with pattern-matching errors. The underlying CC code structure seems to have changed in 2.1.76+ so the regex patterns no longer match.

Verbose output for themes patch shows:

Applying patch: Themes
patch: themes: failed to find objArrMatch

Working patches

These patches still apply correctly on both versions:

• Verbose property, Opusplan[1m], Fix LSP support
• Model customizations, Show more items in select menus
• Thinking verbs, Thinker format, Thinking block visibility
• MCP non-blocking
• Input pattern highlighters (on 2.1.76 npm only)

Note: Input pattern highlighters also fail on the 2.1.81 native binary (failed to find input variable pattern).
