-Because the `uses` is hardcoded, it will always use `cleanup@v1`. This makes it challenging to test how `deploy` will work with a new version of `cleanup`, as you have to create and trigger one-off workflows to validate a new version before it lands. Ideally you could `use` a path instead, but that only works for workflows that have checked out `my-cool-org/repo`; the `deploy` action is much harder to reuse if you have to do that (i.e. imagine these actions are used by various other repos in the `my-cool-org` org).

 Taking our example above, we can make it work however we need to with `dynamic-uses`:
 
 ```yaml
-- uses: jenseng/dynamic-uses@v1.1
+- uses: jenseng/dynamic-uses@v1
+  env:
+    action_ref: ${{ github.action_ref }}
   with:
     # ensure we use the right version:
     #  - within this repo, we want the `sha`
-    #  - from outside the repo, we want the `action_sha`
-    uses: my-cool-org/repo/actions/cleanup@${{ github.repo == 'my-cool-org/repo' && github.sha || github.action_sha }}
+    #  - from outside the repo, we want the `action_ref`
+    #    (we pass it through env, otherwise it picks up `v1` from `jenseng/dynamic-uses@v1`)
+    uses: my-cool-org/repo/actions/cleanup@${{ github.repo == 'my-cool-org/repo' && github.sha || env.action_ref }}
     with: '{ "stuffToCleanUp": "${{ inputs.stuffToDeploy }}" }'
