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 persistent summon session key

Under the hood
Useful1 Signal3
Artifacts

A persistent summon session key is generated and saved to your config, though nothing visibly reads it.

A 32-byte summon session key is created and cached in config but no visible consumer exists in this build.

What

A new helper reads a summon session key from your config file, checks it against an expected pattern, and otherwise generates a fresh 32-byte random hex value, caching it for the session and writing it back to config. What reads the key is not wired up visibly in this build.

Evidence

summonSidKey

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