Align PLUGIN_SLUG with the required plugin directory.

The ZIP currently extracts into formidable-forms/. Lines 7-9 require formidable/ so the Playground can locate the plugin at wp-content/plugins/formidable. Set PLUGIN_SLUG to formidable, or update the consuming blueprint to use formidable-forms.

Blocking. The comment three lines up has the right value; this line has the repo name.

CodeRabbit already flagged the mismatch. Adding the part that makes it a real breakage rather than a naming preference, since I checked it against the plugin's own source rather than against the comment.

classes/models/FrmAddon.php:191 decides whether a plugin is Lite or an add-on by comparing a hardcoded path:

$is_addon = 'formidable/formidable.php' !== $this->plugin_folder;

Unpack the zip this workflow builds and $this->plugin_folder is formidable-forms/formidable.php, so $is_addon is true for core Formidable itself. edd_plugin_updater() then takes the add-on branch: it registers add_version_requirements and add_requirements_to_plugin_info, which exist precisely because "Lite gets its tested and required versions from wordpress.org, add-ons have no such source" (the comment right below that line). Core Lite would be asking the add-on API for data it is supposed to get from wordpress.org, and would go down the add-on licensing path too.

That is on top of every add-on's own dependency check looking for wp-content/plugins/formidable.

Suggested change
PLUGIN_SLUG: formidable-forms
PLUGIN_SLUG: formidable

ZIP_NAME on the next line is already formidable.zip, which is the other half of the tell — the file name got the slug right and the prefix did not.

ZIP_NAME: formidable.zip

Not blocking, and worth deciding now rather than after the other plugins are added.

The object key is fixed, so every run overwrites the last one and the uploaded zip carries no record of what is in it. The concurrency group stops two runs racing, but it does not stop the second run replacing the first run's build. Once more than one person is pushing branches to the Playground, "which branch is live right now" is only answerable by opening the last workflow run.

Two cheap options:

  1. Put the branch in the key (${ZIP_NAME} for a main-ish default, plus branches/<ref>/formidable.zip), and point each Playground blueprint at the one it wants.
  2. Keep the single key, but stamp the object so it can be read back:
--metadata "branch=${BRANCH},commit=${COMMIT}"

Option 2 is one line and keeps the blueprint as it is.

Reachability: External

CWE: CWE-78 — Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Do not interpolate github.ref_name into the shell script.

GitHub expands the expression before Bash parses the script. A branch name containing $(...) can execute command substitution in the Summary step. Pass the value through env:

Proposed fix
       - name: Summary
+        env:
+          BRANCH_NAME: ${{ github.ref_name }}

Confirming CodeRabbit's point here, with the bit that decides whether it is theoretical.

${{ github.ref_name }} is substituted into the script text before bash runs, inside a double-quoted string, so $(...) and backticks in a branch name execute. Git does allow both — checked directly:

$ git check-ref-format --branch 'x`id`y'
x`id`y
$ git check-ref-format --branch 'x$(id)y'
x$(id)y

Severity is low, because workflow_dispatch and branch creation both need write access, so this is not a path for an outside contributor. But the job has R2_ACCESS_KEY_ID / R2_SECRET_ACCESS_KEY in the environment two steps earlier, so it is worth not leaving open. The standard fix is to go through env, where the value is never part of the script text:

Suggested change
- name: Summary
run: |
{
echo "### Uploaded to R2"
echo ""
echo "- **Branch:** \`${{ github.ref_name }}\`"
echo "- **Commit:** \`${{ github.sha }}\`"
