To test dynamic session ID substitution, run a validation script that injects environment variables like CLAUDE_SESSION_ID into text and output files. This verifies that dynamic variable injection works correctly in your automated workflows before deployment.

Environment variable substitution fails when the CLAUDE_SESSION_ID environment variable is not set in your current shell. You must export this variable before running tests to ensure accurate dynamic data population in generated file outputs.

The best way to verify environment variable injection is to run a targeted test that writes substitution results to a file. This confirms whether variables like CLAUDE_SESSION_ID are correctly embedded in generated outputs or if the injection failed.

Yes, you need the CLAUDE_SESSION_ID environment variable set for accurate testing of variable substitution. Without this prerequisite, the test cannot verify whether dynamic session-specific information is correctly populated in your content and output files.

This test is applicable for verifying environment variable injection in automated workflows. It specifically validates dynamic data population by testing session ID substitution within skill content and confirming success or failure through output file verification.
