cmux NEXT composer: append Quote in Reply at the bottom by teamleaderleo · Pull Request #26654 · manaflow-ai/cmux

teamleaderleo · 2026-10-28T04:36:50Z

Leo: "I feel like putting it at the very lowest bit makes sense ... quote in reply ... a little bit useful"

The agent composer now accepts the shared hc-quote selection event and appends the selected text at the bottom of the existing draft. Each quote is separated by a blank line, successive quotes keep their order, and the editor focuses after the trailing blank line. Milkdown continues to render a quiet muted blockquote bar while serializing the prompt as Markdown (> ...).

Added the shared composer quote append helper and event listener for composer, document, and window dispatch targets.
Added bottom and stacked composer gallery fixtures while retaining Backspace unwrap coverage from composer: unwrap quote blocks with Backspace #25681.
Kept the native context-menu event boundary owned by the agent-chat surface; no Swift or transcript files changed.

Validation

Red regression: a063ab5e12f (bun test test/composer-quote-backspace.test.tsx failed before the helper existed: module not found).
Green repair: abf0afa9d17 (bun test test/composer-quote-backspace.test.tsx: 5 passed).
bun run typecheck passed (2,896 files).
Changed-file bunx vp fmt --check and bunx vp lint passed.
python3 scripts/cmux-next/prepush-gate.py --base origin/feat-cmux-next --head HEAD passed.
Browser gallery sweep on GCP passed: 40 tests, 157 expectations.
No native build or local macOS verification; the exact quote visual is represented by the composer gallery bottom and stacked fixtures for the managed capture lane.

Changelog

Changed: Quote in Reply appends muted Markdown quotes at the bottom of the agent composer draft.

Review (codex gpt-6-astra high, next-review): SHIP at abf0afa

No blocking findings.

Non-blocking: The added tests cover Markdown generation and rendering, but never dispatch hc-quote through Composer; event deduplication and final caret placement remain untested.

Review was limited to supplied files; repository-tool access to unchanged dependencies was denied.

teamleaderleo · 2026-10-28T07:00:17Z

Superseded by #26655 (composer insertion, head 89df1bcbca1276ecc07489f6e62bdc434a7c065c) and #26660 (native/transcript route, head 2bee6c10daa99102b321d5cbd29ec8b0ef1678ae). The active owner confirmed that the canonical route is chat.quoteReply({markdown}) → ComposerHandle.quoteReply(markdown).

The surviving composer PR covers the behavior here: preserve the existing draft, append at the bottom even with a focused selection, keep successive quotes ordered, leave an empty reply paragraph/caret after the quote, hide raw quote markers, and send Markdown. It also preserves definition-like selected text and retains the existing Backspace behavior.

Closing this duplicate does not mark the request fixed. The owner of #26655/#26660 owns integration, fresh exact-head independent review, inspected light/dark interaction captures, and landing of the surviving changes.
