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 Advisor Tool configuration dialog title has been updated from "Advisor Tool" to "Advisor Tool (Experimental)" to better communicate its maturity status. A link to the blog post about the advisor strategy is now included.
Evidence
Updated title (search for "Advisor Tool (Experimental)") at line ~543011; blog link "https://claude.com/blog/the-advisor-strategy" at line ~543061
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
