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.
When Claude Code detects setup issues at startup (MCP failures, keybinding errors, etc.), the log message now appends "(run /doctor for details)" so users know how to investigate:
2 setup issues: settings, MCP (run /doctor for details)
Evidence
New dD() function — search for "run /doctor for details"
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
