- #64732: Thinking-prefill retry cascade triggers on reasoning responses with visible content
- PR #21847: fix(agent): skip empty-content nudge when reasoning_content is populated (#21811)
- PR #64733: fix: add _has_visible_content guard to thinking-prefill retry gate

These issues and fixes address incorrect empty-content nudges and thinking-prefill retries firing when reasoning models (e.g. Qwen3, DeepSeek-R1) have already produced reasoning or visible content. Work spans detection of inline thinking, structured-reasoning routing, and post-tool-call behavior.

## TL;DR

- 9 member(s): 1 open issue(s), 2 closed issue(s), 2 open PR(s), 0 merged PR(s), 4 PR(s) closed without merging.
- No fix has been merged to main; one or more PRs were attempted (see below).
- **Recommended:** review the prior/competing PR(s) below. A fix was attempted but not merged; your case may extend or revive that work.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.
- Members outside that structural core may belong to a different underlying problem.
- Pairwise link density `0.19`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
