The /auto-mode-setup recon now reads and reports autoMode keys from the project's .claude/settings.local.json, subject to strict security checks: the file must be a regular file (not a symlink) with link count 1 inside a real .claude directory. The output also notes whether the file is tracked in git (yes — repo-authored vs no — but untracked does not prove user-authored).
Evidence
Local settings autoMode reader (search for "Project \.claude/settings.local.json\ — autoMode keys" and "Tracked in git")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.

Anthropic's release notes agreeChanged auto mode to no longer read autoMode from .claude/settings.local.json (repo-resident); use ~/.claude/settings.json instead
