# NousResearch/hermes-agent · Compression stall loop fixes and cooldown logic

## Open now

- Nothing open on GitHub.

A bug where compaction made no progress caused repeated stalling and context rebuilding each turn. These members address recovery via fallback chains, deterministic fallback summaries, cooldown flooring, and skipping retries during cooldown.

## TL;DR

- 5 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 2 merged PR(s), 2 PR(s) closed without merging.
- A fix was merged to main in PR #113157. Verify it addresses your case.
- **Recommended:** read PR #113157 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-113813`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.40`: 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.

## Closed / duplicate issues

- #112420: \[Bug\]: Compaction stall ("made no progress") continues without compression — oversized context re-triggers compaction every turn; drifted system prompt rebuilt repeatedly
