Create a local backup under ~/.cc-switch/skill-backups/ before removing skill directories. The backup includes all skill files and a meta.json with original skill metadata. Old backups are pruned to keep at most 20. The backup path is returned to the frontend and shown in the success toast. Bump version to 3.12.3.

CC Switch v3.12.3
Tool Search Domain Bypass, Proxy Gzip & o-Series Compatibility, Skills Import Robustness
Overview
CC Switch v3.12.3 adds a Tool Search domain restriction bypass via binary patching, improves proxy compatibility for OpenAI o-series models and gzip compression, and delivers robustness fixes for Skills import, provider forms, and terminal session restore. The Skills import flow has been reworked from implicit filesystem inference to explicit app selection, eliminating incorrect multi-app activation bugs.

Highlights
-
Tool Search domain bypass: New setting to remove Claude CLI Tool Search domain whitelist via equal-length binary patching, with automatic backup and reapply on startup
-
Proxy gzip compression: Non-streaming proxy requests now auto-negotiate gzip compression, reducing bandwidth usage
-
o-series model compatibility: Chat Completions proxy correctly uses
max_completion_tokensfor o1/o3/o4-mini models; Responses API kept on the correctmax_output_tokensfield -
Skills import rework: Replaced implicit filesystem-based app inference with explicit
ImportSkillSelectionto prevent incorrect multi-app activation -
Ghostty terminal support: Fixed Claude session restore in Ghostty terminal
New Features
Tool Search Domain Bypass
Added a setting to bypass Claude CLI Tool Search domain whitelist restrictions.
- Resolves the active
claudecommand from PATH and applies an equal-length byte patch to remove the domain whitelist check - Backups stored in
~/.cc-switch/toolsearch-backups/(SHA-256 of path) so they survive Claude Code version upgrades - The patch auto-reapplies on app startup when the setting is enabled
- Frontend checks patch result and rolls back the setting on failure
Changes
Proxy Gzip Compression
Non-streaming proxy requests now support gzip compression for reduced bandwidth usage.
- Non-streaming requests let reqwest auto-negotiate gzip and transparently decompress responses
- Streaming requests conservatively keep
Accept-Encoding: identityto avoid decompression errors on interrupted SSE streams
o1/o3 Model Compatibility
Proxy forwarding now handles OpenAI o-series model token parameters correctly.
- Chat Completions path uses
max_completion_tokensinstead ofmax_tokensfor o1/o3/o4-mini models (#1451) - Responses API path kept on the correct
max_output_tokensfield instead of incorrectly injectingmax_completion_tokens
OpenCode Model Variants
- Placed OpenCode model variants at top level instead of inside options for better discoverability (#1317)
Skills Import Flow
The Skills import flow has been reworked for correctness and cleanup.
- Replaced implicit filesystem-based app inference with explicit
ImportSkillSelectionto prevent incorrect multi-app activation when the same skill directory exists under multiple app paths - Added reconciliation to
sync_to_appto remove disabled/orphaned symlinks - MCP
sync_all_enablednow removes disabled servers from live config - Schema migration preserves a snapshot of legacy app mappings to avoid lossy reconstruction
Bug Fixes
Provider Form Double Submit
- Prevented duplicate submissions on rapid button clicks in provider add/edit forms (#1352)
Ghostty Session Restore
- Fixed Claude session restore in Ghostty terminal (#1506, thanks @canyonsehun)
Skill ZIP Import Extension
- Added
.skillfile extension support in ZIP import dialog (#1240, #1455)
Skill ZIP Install Target App
- ZIP skill installs now use the currently active app instead of always defaulting to Claude
OpenClaw Active Card Highlight
- Fixed active OpenClaw provider card not being highlighted (#1419)
Responsive Layout with TOC
- Improved responsive design when TOC title exists (#1491)
