 ### Why doesn't tagging @claude from my automated workflow work?
 
-The `github-actions` user cannot trigger subsequent GitHub Actions workflows. This is a GitHub security feature to prevent infinite loops. To make this work, you need to use a Personal Access Token (PAT) instead, which will act as a regular user, or use a separate app token of your own. When posting a comment on an issue or PR from your workflow, use your PAT instead of the `GITHUB_TOKEN` generated in your workflow.

 ## Advanced Configuration
 
-### Custom Environment Variables
-
-You can pass custom environment variables to Claude Code execution using the `claude_env` input. This is useful for CI/test setups that require specific environment variables:
-
-```yaml
-- uses: anthropics/claude-code-action@beta
-  with:
-    claude_env: |
-      NODE_ENV: test
-      CI: true
-      DATABASE_URL: postgres://test:test@localhost:5432/test_db
-    # ... other inputs
-```
-
-The `claude_env` input accepts YAML format where each line defines a key-value pair. These environment variables will be available to Claude Code during execution, allowing it to run tests, build processes, or other commands that depend on specific environment configurations.
