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.

migrate now ends with a prompt audit, and a TODO note ships inside the prompt

You'll notice

Skills not in their notes

The migrate command now finishes by auditing your prompts and tool descriptions for stale wording.

/claude-api migrate
What

After the per-target changes are applied, the migrate subcommand tells the model to audit in-scope prompt text, tool descriptions, and request code against shared/prompt-audit.md.

Details
  • A new Quick Task Reference row routes "is this prompt outdated" and "remove the cruft" questions to the same file.
  • An HTML comment left in the shipped prompt records that the skill's trigger description was deliberately not changed because it is eval-pinned, so the model sees this developer note as part of its context.
Evidence

TODO(prompt-audit): remaining trigger question

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