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.

Read-only skill preloads on the coordinator cannot run shell commands

You'll notice
Useful2 Signal4
Skills

Read-only skill preloads on the coordinator will not run shell commands; work goes to a worker.

What

When a skill is loaded in read-only preload mode on the coordinator, any Bash-style command inside that load is not executed. The model gets back an explanation telling it to delegate the command to a worker instead.

Details
  • Triggered whenever the load is marked as a read-only skill preload; nothing else about the skill is blocked.
  • The substituted result reads "[shell command not executed: read-only skill load on the coordinator - delegate to a worker to run it]".
Evidence

[shell command not executed: read-only skill load on the coordinator \u2014 delegate to a worker to run it]

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