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.

Sessions record a parked job id

Under the hood
Useful2 Signal0
Elsewhere

Sessions now remember which background job they were handed off to, and validate their timestamps more strictly.

What

Session metadata now carries the id of the background job a session was handed off to, and timestamp fields in the metadata reader are validated more strictly.

Details
  • parkedJobId is written when a session is handed off to the background agents view and cleared when it returns
  • the reader parses it as an optional string
  • startedAt, updatedAt and statusUpdatedAt now go through a shared bounds check for finite, non-negative and below a maximum, replacing a bare typeof number test
Evidence

parkedJobId

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