Runtime-instrumentation debugging for bugs that static reading can't pin down — add temporary unconditional JSONL logging to the real code path, reproduce, read the log, then fix. Use when /root-cause lands at MEDIUM/LOW confidence, when a bug involves runtime state, ordering, caching, streaming, concurrency, or manual/UI reproduction, or before a second speculative fix. Skip when a stack trace or a deterministic failing test already proves the cause.
$npx -y skills add crbnos/carbon --skill debugging-difficult-bugsInstalls into the current project.
Run `npx skills use "https://github.com/crbnos/carbon" --skill "crbnos/carbon/debugging-difficult-bugs"` and follow the generated skill instructions now. Read its complete output, redirecting it to a temporary file first if necessary. Resolve relative paths from the supporting-files directory it provides.
Use the skills in "https://github.com/crbnos/carbon" that are relevant to the current task. Run `npx skills add "https://github.com/crbnos/carbon"` and select the relevant skills, then follow their instructions.
