# NousResearch/hermes-agent · Circuit breaker ignoring tirith_fail_open setting

## Open now

- Nothing open on GitHub.

A bug was identified where the circuit breaker in check_command_security() did not respect the tirith_fail_open configuration, and multiple fix attempts address this behavior. The members center on ensuring the fail_open setting is honored when the circuit breaker is open.

## TL;DR

- 7 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 0 merged PR(s), 6 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.29`: 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.
