Problem Statement

Long pasted text is no longer auto-captured as a file attachment (e.g. "pasted_text.txt") — it now arrives as raw inline text in the message and silently truncates at 50,000 characters ("[Message truncated - exceeded 50,000 character limit]"). This used to work automatically on paste in earlier versions.

Environment: Claude Code VS Code native extension, Windows 11.

Impact: pasting long terminal/log output (common when debugging) loses the tail of the content past 50k chars with no warning before truncation, and no way to recover the rest without re-running the command and saving to a file manually.

Request: restore auto-attach-on-paste for long text blocks (or add a configurable threshold/setting to opt into it), so large pastes become a file reference instead of being silently truncated.

Proposed Solution

Long pasted text is no longer auto-captured as a file attachment (e.g. "pasted_text.txt") — it now arrives as raw inline text in the message and silently truncates at 50,000 characters ("[Message truncated - exceeded 50,000 character limit]").

Impact: pasting long terminal/log output (common when debugging) loses the tail of the content past 50k chars with no warning before truncation, and no way to recover the rest without re-running the command and saving to a file manually.

Proposed Solution:
Restore auto-attach-on-paste for text blocks above a size threshold (e.g. ~5-10k chars), converting them into a file reference (like image paste already does) instead of inlining raw text. If a hard 50k inline limit must stay for cost/context reasons, at minimum:

1. Warn before truncating, not just after (e.g. "this paste is 80k chars, attach as file instead?").
2. Make the threshold configurable via settings.json.
3. Ensure the truncation warning states how many characters were dropped, so the user knows content is missing rather than assuming the paste completed.
