DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
The /debug skill now explicitly supports enabling debug logging mid-session. When debug logging was off, invoking /debug turns it on and shows a message that nothing prior was captured. Users are instructed to reproduce the issue, then re-read the log.
Evidence
Debug logging toggle (search for "## Debug Logging Just Enabled")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
