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.

Empty placeholder registry runs when you open the background agents view

Under the hood
Useful1 Signal2
Agents

Opening the background agents view runs an empty registration step with no visible effect.

A placeholder registry is called from the /agents view but registers an empty object nobody reads.

/agents
What

Opening the background-agents fleet view (/agents) now loads an extra module and calls a registration step before drawing anything. It registers an empty object and no code reads it back, so there is no visible effect either way.

Details
  • registerToolHosts() stores a literal {} into a per-host singleton; the singleton exposes a runtime value that falls back to a frozen empty object, plus a flag saying whether anything was registered.
  • Neither of those is read anywhere in the build, and {} is the only value ever registered. This is a seam wired up ahead of what will eventually fill it.

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