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.

Claude Code v2.1.232

Clear error when every tool an agent could use is denied

You'll notice
Useful3 Signal2
Subagents

If your permissions deny every tool an agent could use, you now get a clear explanation.

What

If your permission settings deny all the tools a subagent type is allowed to use, launching or resuming that agent now fails with a message saying so, instead of a misleading "not found".

Details
  • Applies to launching a subagent by type, resuming one, and the workflow agent({agentType}) path.
  • Two new telemetry outcomes record it: subagent_type_tools_denied and subagent_resume_tools_denied.
Evidence

is unavailable because every tool it may use is denied by the current permission settings.

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