Cloud Skills Are Still Just Skills (vexjoy.com)

Anthropic recently launched two new features for Claude Code: /ultraplan and /ultrareview, which operate on cloud servers and introduce a verification loop absent in previous skills. /ultraplan generates a multi-phase implementation plan with checkpoints, while /ultrareview provides a code review pipeline that includes a merge-readiness assessment. Both are billed after three free runs, costing between $5 and $20 depending on the codebase size. However, these features lack transparency, as users cannot view the prompts or pipeline stages, limiting the ability to learn from and adapt these skills, in contrast to earlier open-source skills. This shift towards closed, cloud-based services raises concerns about the future of the skill ecosystem. While Anthropic's engineers advocate for skills as open, composable methodologies, the introduction of premium, opaque features risks creating a divide between accessible and proprietary skills. Users proficient in skill development may benefit from open skills, while those less experienced may have to rely on costly closed options. The absence of insightful interaction with the new features may hinder the growth of new developers in the AI/ML landscape, highlighting the tension between commercial interests and the educational value of transparency in skill-building.
