📝 Walkthrough

Walkthrough

GetTool.Handle now stages downloads in a .part file, applies permissions, and renames the completed file into place. Failed operations remove the partial file and preserve the existing tool.

Changes

Tool replacement

Layer / File(s)	Summary
Staged replacement and cleanup internal/app/components/customhandlers/get_tool.go	GetTool.Handle removes stale .part files, downloads and chmods a temporary file, then renames it into place. Download, chmod, and rename failures remove the temporary file and preserve the existing tool.
Replacement failure and recovery tests internal/app/components/customhandlers/get_tool_test.go	Tests verify interrupted-download cleanup after a successful replacement and preservation of the existing tool after an HTTP 404 download error.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to bebcc

Tool downloads now replace existing tools through a partial file, preserving the prior tool if download fails. No concrete merge-blocking risk remains.

In `@internal/app/components/customhandlers/get_tool.go`:
- Line 49: Update the handler around c.Get(), os.Chmod(), and os.Remove to
download and chmod a temporary sibling file before replacing destination,
atomically promote it only after both operations succeed, and remove the
temporary file on failure. Preserve the existing destination content when either
operation fails, and add a failure-path test verifying the previous tool content
remains intact.
