# NousResearch/hermes-agent · Memory tool replace/remove edge case fixes

## Open now

- 4 issues, 2 PRs open on GitHub.
- #35121: Treat memory quota exceeded as a non-retryable tool-loop failure
- #35995: \[Feature\]: memory_patch tool — regex-based replace for built-in memory entries
- #37911: Hermes Desktop for Mac session got stuck after unwanted coding action and memory tool retry loop
- #60089: \[Bug\]: memory replace → "Multiple entries matched" → fallback add creates duplicate entries with no signal
- PR #45777: feat(memory): add regex 'patch' action to the memory tool
- PR #71819: fix(memory): disambiguate replace when new_content already exists

These issues and PRs address several related problems in the memory tool's replace and remove operations: zero-match cases not returning entry previews, ambiguous multi-match fallbacks silently creating duplicate entries, and retry loops hanging when at capacity or hitting deterministic failures.

## TL;DR

- 29 member(s): 4 open issue(s), 3 closed issue(s), 2 open PR(s), 2 merged PR(s), 18 PR(s) closed without merging.
- A fix was merged to main in PR #41755. Verify it addresses your case.
- **Recommended:** read PR #41755 (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: `partially_resolved` · deciding PR(s): `pr-55526`. 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evidence (`STRUCTURAL_PARTIAL`): some members are connected by structural evidence (shared changed files, or a closing/superseded reference); the rest are joined by an automated relevance judgement over their text.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 `0.06`: 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.
