Source Intelligence

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.

Revamped Plan Mode Workflow

What

Plan mode instructions have been completely rewritten for a more collaborative "pair-planning" experience.

Details
  • New framing: "You are pair-planning with the user"
  • Introduces "The Loop" pattern: Explore → Update plan file → Ask user → repeat
  • New "First Turn" guidance: Start with a quick scan, write a skeleton plan, ask initial questions
  • "Asking Good Questions" section: Never ask what you could find by reading code; batch related questions; focus on things only the user can answer
  • Simplified tool references: "to read code" instead of verbose tool lists
Evidence

New workflow text (search for "pair-planning with the user", "First Turn")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
