Qwen Code lets users reference prior sessions from @ completion with read-only summaries

LaZzyMan · ghdev · 2026-07-20

This Qwen Code PR adds a new way to reference prior project sessions directly from the interactive @ completion flow.

What it does

lets users pick a previous session from @ completion
inserts an @session:<id> reference
injects a deterministic, read-only transcript summary
keeps visible user and assistant text while compressing tool output into short status lines
preserves the newest content within an 8k-token budget

UI changes

The completion menu is now grouped into:

Left/right arrows switch categories only when multiple groups are present, so normal cursor movement is unchanged otherwise.

Goal

Instead of resuming or forking an old session, users can reuse relevant history while keeping the current conversation independent.
