What it is
Link custom-named AWS key variables into one credential for [re-signing](/docs/en/sandboxing#re-sign-aws-requests)
Anthropic's own wording. Read off All settings, captured 2026-09-22.
Presence across releases
0The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.
First cited
2The earliest release whose published evidence quoted sandbox.credentials.awsPairs was v2.1.257, 1 Sep 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table above.
Names beside it
Every settings key in the inventory starting sandbox.credentials, up to twelve of them.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the settings key does. All settings keys.
