Extend secret redaction to .md, .mdx, .yml, .jsonl files

[Copilot]

Summary

Extended the secret redaction functionality to process .md, .mdx, .yml, and .jsonl files in addition to the existing .txt, .json, and .log files.

Changes

The secret redaction script (pkg/workflow/js/redact_secrets.cjs) now processes a broader set of file types commonly used in agentic workflows:

• Markdown files (.md, .mdx) - For workflow documentation and AI-generated reports
• YAML files (.yml) - For configuration files and workflow definitions
• JSON Lines files (.jsonl) - For structured log output and data files

Modified Files

pkg/workflow/js/redact_secrets.cjs

• Updated targetExtensions array to include the new file types (line 129)
• Updated JSDoc documentation to reflect the expanded file type coverage

pkg/workflow/js/redact_secrets.test.cjs

• Added comprehensive test coverage for all new file extensions
• Verified correct secret redaction behavior across all file types

Testing

All tests pass successfully:

• ✅ 9/9 redact_secrets.test.cjs tests
• ✅ 572/572 total JavaScript tests
• ✅ TypeScript type checking
• ✅ Code formatting and linting

The new test case creates files with each extension type and verifies that secrets are properly redacted using the same pattern (first 3 characters + asterisks for remaining length).

Impact

This change ensures that sensitive data in markdown documentation, YAML configurations, and JSON Lines logs are properly redacted before artifacts are uploaded, improving security across a wider range of workflow output files.

Original prompt

Extend the target extensions in the secret redaction javascript to .md, .mdx, .yml, .jsonl files

const targetExtensions = [".txt", ".json", ".log"];
