Claude API skill spreads across more tools

This is less a flashy launch than a distribution play: Anthropic is turning API know-how into a portable workflow layer that keeps Claude current as the platform changes.

• –`/claude-api migrate` and `/claude-api managed-agents-onboard` turn migration and onboarding into guided workflows instead of manual doc digging.
• –The skill’s value compounds because it stays current as SDKs and model behavior change, which is exactly where teams usually get burned.
• –Open sourcing it makes Claude’s API conventions easier to adopt across third-party coding tools, not just inside Claude Code.
• –The real win is developer retention: if the skill lives where people already code, fewer API upgrades will stall on friction.
