If you see rate-limit errors during install or search, set `GITHUB_TOKEN` in your `.env` file to increase the limit to 5,000 requests/hour.

+## Bundled skill updates (`hermes skills reset`)
+
+Hermes ships with a set of bundled skills in `skills/` inside the repo. On install and on every `hermes update`, a sync pass copies those into `~/.hermes/skills/` and records a manifest at `~/.hermes/skills/.bundled_manifest` mapping each skill name to the content hash at the time it was synced (the **origin hash**).
+
+On each sync, Hermes recomputes the hash of your local copy and compares it to the origin hash:
+
+- **Unchanged** → safe to pull upstream changes, copy the new bundled version in, record the new origin hash.
+- **Changed** → treated as **user-modified** and skipped forever, so your edits never get stomped.
+
+The protection is good, but it has one sharp edge. If you edit a bundled skill and then later want to abandon your changes and go back to the bundled version by just copy-pasting from `~/.hermes/hermes-agent/skills/`, the manifest still holds the *old* origin hash from whenever the last successful sync ran. Your fresh copy-paste contents (current bundled hash) won't match that stale origin hash, so sync keeps flagging it as user-modified.
+
+`hermes skills reset` is the escape hatch:
+
+```bash
+# Safe: clears the manifest entry for this skill. Your current copy is preserved,
+# but the next sync re-baselines against it so future updates work normally.
+hermes skills reset google-workspace
+
+# Full restore: also deletes your local copy and re-copies the current bundled
+# version. Use this when you want the pristine upstream skill back.
+hermes skills reset google-workspace --restore
+
+# Non-interactive (e.g. in scripts or TUI mode) — skip the --restore confirmation.
+hermes skills reset google-workspace --restore --yes

+Each profile has its own `.bundled_manifest` under its own `HERMES_HOME`, so `hermes -p coder skills reset <name>` only affects that profile.
