# NousResearch/hermes-agent · Performance and timing variance improvements in tools

## Open now

- Nothing open on GitHub.

Two distinct themes: persisting an OSV malware-check verdict cache to disk (with a duplicate or salvage entry), and investigating high connection-time variance in a stdio MCP server test causing false-positive watchdog alerts.

## TL;DR

- 3 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 1 PR(s) closed without merging.
- A fix was merged to main in PR #101592. Verify it addresses your case.
- **Recommended:** read PR #101592 (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: `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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.67`: 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

- #68416: hermes mcp test shows 5x connection-time variance (1.8s–9.8s) on identical stdio MCP server calls, causing false-positive watchdog alerts
