# NousResearch/hermes-agent · Add per-memory invalidate and restore tools to hindsight

## Open now

- Nothing open on GitHub.

These items concern adding hindsight_invalidate and hindsight_restore tools to address the limitation that stale facts previously could only be removed by deleting the entire memory bank. The work includes a hindsight-client version bump to 0.9.0.

## TL;DR

- 5 member(s): 0 open issue(s), 1 closed issue(s), 0 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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

- #23023: hindsight: no per-memory delete or exclude — stale facts can only be removed by nuking the bank
