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.

Feature flag
tengu_code_diff_cli On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

This account: on · anonymous baseline: on · compiled default in v2.1.50: no gate table built for this version

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.50. It isn't a statement about your account. What a flag value here can and cannot tell you

  • Fixed issue where GitHub issue/PR references with fewer than 3 digits (e.g., #12) were incorrectly linkified; now only references with 3+ digits are processed (search for /(?<!\w)#(\d{3,})\b/)
  • Fixed duplicate MCP tools when connecting to multiple servers that provide tools with the same name (search for "wG([...Y6.mcp.tools" — deduplication by name)
  • Fixed memory leak in ring buffer clear() method that wasn't resetting the buffer array (search for "this.buffer.length = 0")
  • Removed "Penguin mode promo" discount display that was showing in the fast mode UI (search for removal of Bl4 component)
  • Fixed cleanup of LSP diagnostics that had already been sent as attachments (search for "if (J.attachmentSent) j96.delete(O)")
  • Removed the code diff footer feature flag and setting (codeDiffFooterEnabled) that was behind tengu_code_diff_cli - this functionality is now handled by the new /diff command
