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.

Session capability record gains three slots, loses one

Under the hood
Useful2 Signal3
Sessions

Session capabilities gained slots for a live tether, workflow skill and kept deferred tools.

Only storage slots; the build does not say what the answers are.

What

The per-session record of which features are switched on dropped the plan-mode resume guard and gained slots for a live tether gate, the workflow authoring skill and kept deferred tools. These are only the places the answers are stored; the build does not say what the answers are.

Evidence

workflowAuthoringSkillAvailable

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