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.

Changed#

  • Optimized Node.js module imports - The codebase now uses more specific imports instead of importing entire modules:
  • node:process - Now imports only the cwd function instead of the entire module
  • node:stream and stream - Now imports only the PassThrough class instead of the entire module

Technical Details#

  • Replaced default imports with named imports for better tree-shaking and reduced memory footprint:
  • import mu2 from "node:process"import { cwd as RLA } from "node:process"
  • import wMA from "node:stream"import { PassThrough as XvQ } from "node:stream"
  • import NRB from "stream"import { PassThrough as Yy6 } from "stream"

Performance Impact#

This change reduces the application's memory usage by only importing the specific functions and classes needed rather than loading entire Node.js modules. Users may experience slightly faster startup times and reduced memory consumption, though the impact will likely be minimal in typical usage scenarios.

Additional Notes#

  • The update includes 154 internal renames, likely due to the minification process adjusting variable names
  • No functionality changes - this is purely an optimization update
  • The structural similarity remains at 100%, confirming no architectural changes

Not individually listed upstream

v1.0.47 does not have its own entry in Anthropic’s official changelog, because prerelease builds are often folded into a neighbouring release. Browse the full changelog for the closest official notes. Everything else on this page came out of the bundle instead, which is why the two lists don't match.

System prompt
