Transform Copilot conversation.md headers for step summaries #9301

Copilot · 2026-01-08T01:55:05Z

Summary

Added a JavaScript markdown transformer that increases header levels by 1 (# to ##, ## to ###, etc.) for the Copilot CLI conversation.md output before writing to GitHub Actions step summary.

Implementation:

Created markdown_transformer.cjs with increaseHeaderLevel() function
Handles ATX-style headers (# prefix) using regex
Preserves headers in code blocks (both ``` and ~~~ fences)
Normalizes Windows line endings (\r\n to \n)
Maximum header level is 6 (h6)
No external dependencies - regex only

Testing:

35 comprehensive test cases covering all scenarios
Integration test in log_parser_bootstrap.test.cjs
All 2527 JavaScript tests pass

Integration:

Transformer applied in log_parser_bootstrap.cjs when Copilot conversation.md is detected
Transforms headers before writing to step summary
No impact on other parsers or workflows

Updates:

Merged latest main branch with runtime-import documentation
All merges completed successfully with clean history

Original prompt

Add a JavaScript markdown transformer that increases the header level by 1 (# to ## ...).

It should be used to transform the markdown generated by copilot summary.md that gets written to the agent output step summary.

Put in actions/setup/js.

Add extensive testing. Do not use any external package, regex only.
