 ## Watch out for `dash-case`
 
-:::warning Critical Issue: kebab-case Action IDs Cause NaN
-
-The nunjucks compiler can run into issues if the `id` fields in your template steps use dash characters, since these IDs translate directly to JavaScript object properties when accessed as output. **This is a common source of bugs where template expressions return `NaN` instead of expected values.**
-
-**The Problem:**
-When you use kebab-case action IDs like `fetch:component-id`, template expressions like:
-```yaml
-${{ steps.fetch-component-id.output.componentId }}
-```
-Are evaluated as JavaScript: `steps.fetch - component - id.output.componentId`, which performs subtraction operations and results in `NaN`.
-
-**Solutions:**
-
-1. **Recommended:** Use `camelCase` for your action IDs:
-
-```yaml
-steps:
-  - id: fetchComponentId    # ✅ Use camelCase
-    ...
-
-  - id: publishPullRequest  # ✅ Use camelCase
-    input:
-      repoUrl: ${{ steps.fetchComponentId.output.repoUrl }}  # ✅ Works correctly
-```
-
-2. **Alternative:** Keep dash-case and use bracket notation for property access:
-
-```yaml
-steps:
-  - id: fetch-component-id   # ⚠️  Dash-case requires bracket notation
-    ...
-
-  - id: publish-pull-request
-    input:
-      repoUrl: ${{ steps['fetch-component-id'].output.repoUrl }}  # ✅ Works with brackets
-```

 Prefer to use `camelCase` over `snake_case` or `kebab-case` for these actions if possible, which leads to better reading
 and writing of template entity definitions.
