Highlights

Tracks upstream claude-code-cache-fix@3.1.0 and drops preload-mode wrapper support entirely. Proxy mode is the only mode now — preload didn't work on the Bun-binary CC (v2.1.113+) anyway, and the 67 MB Windows wrapper .exe was costing every user on every download.

VSIX size: ~30 MB → ~20 KB (7 files).

What changed

Removed — preload mode + wrapper

  • Deleted ClaudeCodeCacheFixWrapper.exe (67 MB) and wrapper.js.
  • Removed commands Enable / Disable (preload). Proxy commands Enable Proxy Mode / Disable Proxy Mode remain.
  • Removed 13 preload-only settings (skipRelocate, skipContinueTrailerStrip, skipReminderStrip, skipCacheControlSticky, normalizeIdentity, normalizeCwd, normalizeSmoosh, imageKeepLast, stripGitStatus, outputEfficiencyReplacement, debug, etc.).
  • On activate, leftover claudeCode.claudeProcessWrapper settings written by 0.6.x are cleared (only when the path looks like ours).

Added — sync to v3.1.0 upstream defaults

Three previously dormant proxy extensions are now enabled by default; the override file at ~/.claude/cache-fix-proxy-extensions.json mirrors that. Real-world testing of these together recovered cache hit rate from 5.9% → 99.9% in ~2 calls.

  • smoosh-split (order 320) — peels system-reminder blocks out of tool results.
  • content-strip (order 330) — removes per-turn bookkeeping text.
  • tool-input-normalize (order 340) — cache-stable JSON serialization for tool_use inputs.

Plus two env-var-controlled extensions, both wired through VS Code settings:

  • prefix-diff — opt-in via prefixDiff setting (now actually wires CACHE_FIX_PREFIXDIFF=1).
  • deferred-tools-restore — default-on; opt-out via skipDeferredToolsRestore. Addresses MCP reconnect race conditions.

Changed — settings now actually wire to the proxy

In 0.6.x the proxy-mode skip* settings only updated the (now-deleted) preload wrapper config — they had no effect on the proxy. Fixed: every skip* toggle now flips the corresponding extension's enabled flag in the override file before each proxy spawn, and changes restart the running proxy automatically.

Settings panel collapsed from 5 sections / 28 toggles to 3 sections / 17 toggles. Less surface, every remaining knob does something.

Migration

Settings reused with new wiring:

  • skipSmooshSplit — was preload-only, now flips proxy smoosh-split.
  • skipDeferredToolsRestore — was preload-only, now sets the proxy env var.
  • prefixDiff — was preload-only, now sets the proxy env var.

Setting renamed: skipToolUseInputNormalize → skipToolInputNormalize. Copy your value over; VS Code marks the old key as "Unknown configuration setting".

Settings deleted (no proxy equivalent yet upstream): skipRelocate, skipContinueTrailerStrip, skipReminderStrip, skipCacheControlSticky, normalizeIdentity, normalizeCwd, normalizeSmoosh, imageKeepLast, outputEfficiencyReplacement, debug. For stripGitStatus, use the native CLAUDE_CODE_DISABLE_GIT_INSTRUCTIONS=1 env var (works on Bun-binary CC too).

Compatibility

  • Requires claude-code-cache-fix@>=3.0.1 for proxy at minimum; >=3.1.0 for the new default-on extensions and env-var-controlled features.
  • httpsProxy / noProxy end-to-end honored only on >=3.0.3.
  • Auto-installed via volta install or npm install -g if missing on activate.

Install

Download claude-code-cache-fix-0.7.0.vsix below, then:

code --install-extension claude-code-cache-fix-0.7.0.vsix

On first activate the extension installs claude-code-cache-fix@latest (which will be 3.1.0+) automatically. Restart any active Claude Code session afterward.
