Reviewed both .github changes. The Lychee enablement is consistent with the existing Ultralytics Actions workflow, but the Dependabot directory prevents the new weekly GitHub Actions update job from working. One fix is required.

• 💡 MEDIUM .github/dependabot.yml:9 For the github-actions ecosystem, Dependabot requires directory: "/" to discover workflow files under .github/workflows; the current path causes this configuration not to monitor the repository's actions, so the promised weekly updates will not run. Change this to /. (docs.github.com)

Dependabot supports directory: "/.github/workflows" for the github-actions ecosystem — this is the org convention used in ultralytics/ultralytics, sdk, skills, openapi and lite, and it demonstrably works (e.g. ultralytics/ultralytics "Bump actions/stale from 10 to 11 in /.github/workflows", 2026-07-28). Keeping as is.

Review 2: no new issues found. The prior Dependabot directory concern is not repeated because the maintainer’s reply settled it with repository evidence. The added issue forms and Lychee enablement are consistent with the existing workflow. LGTM.

The structured issue templates, weekly Dependabot updates, and Lychee link checks strengthen repository maintenance and support without changing JSON2YOLO conversion behavior.
