# NousResearch/hermes-agent · Fix repeated stat calls and warn-once latch bug

## Open now

- Nothing open on GitHub.

These items address a performance problem where get_hermes_home() re-stats the active profile on every call when HERMES_HOME is unset, and a related bug where the warn-once latch only engages on the warning branch rather than on the first check, plus broader config and profile read optimizations on hot paths.

## 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 #120402. Verify it addresses your case.
- **Recommended:** read PR #120402 (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-120402`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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

- #90065: get_hermes_home() re-stats active_profile on every call when HERMES_HOME is unset (warn-once latch never engages)
