# NousResearch/hermes-agent · Pre-write syntax validation gate for JSON/YAML/TOML

## Open now

- Nothing open on GitHub.

These issues and PRs concern a bug where write_file() writes invalid JSON/YAML/TOML to disk before running its syntax check, reporting the write as successful. The proposed fix moves the syntax validation gate to before the disk write, rejecting invalid content upfront.

## TL;DR

- 11 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 9 PR(s) closed without merging.
- A fix was merged to main in PR #60710. Verify it addresses your case.
- **Recommended:** read PR #60710 (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-60710`. 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evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.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 `0.18`: 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

- #60525: write_file() commits to disk before its own JSON/YAML/TOML syntax check runs — invalid content is written and reported as successful
