Herdr Pre-release Audit

Use this skill only inside the herdr repository.

Read references/pre-release-audit.md and follow its workflow. Treat it as the source of truth for:

• choosing the release base ref
• inspecting first-parent history and merged PRs
• auditing docs/next/CHANGELOG.md
• auditing docs/next/README.md and staged website docs
• checking issue reference lines
• deciding when to run just release-docs-check
• producing the final release-readiness report

Do not edit files during the audit unless the user explicitly asks to apply fixes. When applying fixes, keep changes scoped to the files named in the reference workflow.
