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.

Conversation Compaction Prompt Updates

The conversation compaction (summary) system now uses a two-prompt approach: one for full conversation summaries and a separate prompt for summarizing only the recent portion of a conversation when earlier context is retained. Both prompts include detailed section structure (Primary Request, Key Technical Concepts, Files, Errors, Problem Solving, User Messages, Pending Tasks, Current Work, Next Step).

Evidence

Dual compaction prompts (search for "Your task is to create a detailed summary of the RECENT portion")

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