core-v1.5.5 - Hardened Windows Packaging, Inno Setup Installer & Uninstaller, and Concurrency-Safe Update Checker
What's Changed in core-v1.5.5
🚀 Packaging, Distribution & Safety Hardening
- Windows Installer (
watch-skill-installer.exe):- Non-elevated (
PrivilegesRequired=lowest) targeting%LOCALAPPDATA%\Programs\watch-skill\. - Ownership Safety Guarantee: Pre-existing unmanaged agent skills (without
.watch-skill-managedmarker) are strictly preserved and never overwritten. - Automatically installs AI Agent skills to
%USERPROFILE%\.gemini\config\skills\watch-video-cli\and%USERPROFILE%\.claude\skills\watch-video-cli\. - Token-level
HKCU\Environment\Pathdeduplication and Win32WM_SETTINGCHANGEbroadcast. - Checks for FFmpeg availability and invokes silent winget install when missing.
- Non-elevated (
- Standalone Uninstaller (
watch-skill-uninstaller.exe):- Ultra-lightweight native binary (~2.1 MB) distributed directly on GitHub Releases.
- Idempotent and clean uninstallation without requiring Python runtime.
- Cleans application directory, removes registry PATH token cleanly, removes managed AI Agent skills (preserves unmanaged user skills), and preserves FFmpeg and user data (
~/.watch-skill).
- Core CLI Executable (
watch-skill-windows-x86_64.exe):- Fully self-contained portable Windows CLI binary with all perception, OCR, and CLI contract capabilities.
- Smart Non-blocking Auto-Update Check:
- Cross-process atomic file locking (
~/.watch-skill/update-check.lock) with stale recovery to prevent request storms on concurrent invocations. - Normalizes canonical release tags (e.g.,
core-v1.5.5->1.5.5). - Failure backoff updates cache to avoid hammering GitHub API on rate-limits (HTTP 403/429) or timeouts.
- Merges latest notification state cleanly without worker overwrite races.
- Emits notifications strictly to
sys.stderrto keepstdoutand--jsoncontracts 100% clean for AI Agents. - Disables cleanly via
WATCHSKILL_NO_UPDATE_CHECK=1orWATCHSKILL_OFFLINE=1.
- Cross-process atomic file locking (
