What changed
| # | What the source says | Status |
|---|---|---|

| 02 | It installs with npx skills add caru-ini/stack-diagram and, per the README, works with Claude Code, Codex, Cursor and other agents that support skills; in the Claude apps you upload a zip from the releases page. | Reported |
| 03 | Logos are fetched at build time from svgl, devicon, gilbarbara/logos or the brand's own repository, and cloud icons from AWS, Google Cloud and Azure's own packages; the README says they are never recolored or redrawn. | Reported |
| 04 | Output is one self-contained HTML file by default, rendered in light and dark themes, with PNG (via Playwright and Chromium), a React component or a Claude artifact as alternatives; it needs Python 3.9+. | Reported |
| 05 | After drawing, the agent offers to post the diagram to a public gallery at stacks.caru.moe, and the README says it posts only after you say yes twice and never sends your prompt. | Reported |
