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.

A new storage backend is being wired through the whole CLI

Storage Backend

Plugins, MCP, settings, themes and dozens of screens now accept the new storage handle nobody supplies.

Storage v5 threading spans the CLI with filesystem fallbacks everywhere and no visible source of a handle.

What

An optional alternative storage handle, referred to internally as storage v5, is now passed into plugin install and marketplace code, MCP server commands, settings writes, session and history reads, daemon and terminal bookkeeping, theme writes, task registries and dozens of UI components. Mentions went from 37 to 689. Every call site still falls back to reading and writing files directly when no handle is supplied, and nothing in the source shows what decides whether a run gets one.

Details
  • Writes pass a durability hint, either followAtomic or inPlace.
  • Because of the fallbacks, behaviour with no handle is identical to the previous build.

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