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.

Control-tag sanitizing rules are now shared

Under the hood
Useful2 Signal3
Permissions

The rules that neutralise control tags in subagent output are now shared with a new assistant-output scanner.

What

The rules that neutralize control tags and permission-escalation phrasing in subagent output are now one shared list, reused with fresh pattern copies by a new scanner for assistant output. Subagent behaviour is unchanged.

Details
  • The escalation set covers settings JSON, bypassPermissions, --dangerously-skip-permissions and permission allow/deny phrasing.
Evidence

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