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.

Preloading a skill no longer does the built-in command's real work

You'll notice
Useful3 Signal2
Skills

Preloading a skill no longer runs the expensive work of codebase analysis or /insights.

/insights
What

Two built-in commands now detect that they are being loaded as part of a skill preload and skip their work: the codebase-analysis prompt skips its expensive preparation, and /insights returns a placeholder instead of generating a report. The report is still produced normally when you run /insights yourself.

Details
  • Both branch on the existing skill-preload and read-only-load options rather than a new flag.
  • The tool-result formatter gained a matching read-only branch that tells the model nothing was executed.
Evidence

The /insights report is generated only when the command is invoked directly.

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