+<!-- action-docs-runs source="action.yml" -->
+
+## Running locally
+
+The check logic has no dependency on the composite action wrapper beyond
+`curl`, `awk`, and `diff` on `PATH`. From a repo's root:
+
+```bash
+CANONICAL_URL=https://gitea.pixelparasol.com/stat-tackler/stat-tackler-infra/raw/branch/main/docs/CLAUDE.shared.md \
+  TARGET=CLAUDE.md sh -c '
+    extract() { awk "/<!-- SHARED:BEGIN/{f=1} f{print} /SHARED:END -->/{f=0}" "$1"; }
+    tmp=$(mktemp)
+    curl -sfSL "$CANONICAL_URL" -o "$tmp"
+    extract "$tmp" > "$tmp.canon"
+    extract "$TARGET" > "$tmp.mine"
+    diff -u "$tmp.canon" "$tmp.mine" && echo "matches canonical"
+    rm -f "$tmp" "$tmp.canon" "$tmp.mine"
+  '
+```
+
+`GITEA_TOKEN` is only needed if `stat-tackler-infra` becomes private; it is
+otherwise safe to omit.
