This command:
claude-code-transcripts web
Should list all of the Claude Code for web transcripts, but it doesn't.
This one should convert one given a session ID:
claude-code-transcripts web sess_123
It is also broken.
This is because Anthropic changed the undocumented APIs that these commands use. I have not yet been able to reverse-engineer an alternative - the /v1/sessions one at least appears to only work using hits to claude.ai with web cookies, I'm not sure what happened to /v1/session_ingress/session/{id}.
