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.

strictPluginOnlyCustomization Policy [In Development]

What

New managed settings policy that blocks non-plugin customization sources for specified surfaces (skills, hooks, etc.).

Status

Available in managed settings but not broadly documented.

Details
  • Can be set to true (locks all surfaces) or an array of specific surface names (e.g., ["skills", "hooks"])
  • false is an explicit no-lock override
  • Plugin, policySettings, built-in, builtin, and bundled sources are always allowed
  • Invalid values are logged as warnings
Evidence

Plugin-only customization policy (search for "strictPluginOnlyCustomization")

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