VS Code save events not triggered on Claude Code file edits

Problem Statement

When Claude Code writes or edits files from within the VS Code extension, changes are written directly to disk without going through VS Code's editor buffer. As a result, onDidSaveTextDocument is never fired, silently breaking any extension or workflow that depends on VS Code's save lifecycle.

This is a silent failure — no error is shown, but save-triggered workflows stop working entirely when Claude Code is in use. Affected workflows include:

• Salesforce DX auto-deploy — relies on onDidSaveTextDocument to push changes to a scratch org on save; Claude Code edits completely bypass this, breaking the deploy pipeline
• Prettier / ESLint format-on-save — never triggered, leaving files unformatted after Claude Code edits
• Any extension using workspace.onDidSaveTextDocument or onWillSaveTextDocument

Proposed Solution

Route file writes/edits through the VS Code editor buffer using workspace.openTextDocument + TextEditor.edit (or equivalent), then call document.save() or trigger a save via the VS Code API. This would cause onDidSaveTextDocument to fire correctly, making Claude Code edits behave identically to a manual user save.

Cursor handles this correctly by routing edits through the editor buffer and triggering a save through the VS Code API.

Alternative Solutions

No viable workaround exists for users whose workflows depend on onDidSaveTextDocument. The event simply never fires when Claude Code makes edits, and there is no way to intercept or re-trigger it from the extension side.

Additional Context

This was surfaced via the /feedback command inside Claude Code.
Related to #14183 (closed as stale) — reopening as the issue is still present and affects additional use cases beyond formatting, including Salesforce DX deployment pipelines.
