Want your agent to check before it adds a package? Connect Claude Code, Cursor or Codex to StackPrism. Setup steps
Ask Prism Agent about t3-oss/create-t3-app
Map the repo (free) and ask what to fix first, whether an upgrade is safe, or what breaks if a service goes down. Prism Agent checks live sources before it answers.
How this report works
StackPrism read package.json and pnpm-lock.yaml from the default branch of t3-oss/create-t3-app and checked its 94 packages against GitHub, OSV.dev, deps.dev, CISA KEV, FIRST EPSS, npm and endoflife.date. Nothing was installed or run, and there’s no AI in the findings: each one comes from a source you can open.
Vulnerabilities come from OSV.dev, with known-exploited ones from CISA marked and listed first. Runtimes, frameworks and base images are checked against endoflife.date, and packages against their registry for deprecations and major versions you’ve fallen behind. The fix task above lists every change with the file to edit.
This page refreshes every few hours; after you push a fix, “Check again” runs it now. Only the repo’s root is read. For an app in a sub-folder, paste the folder’s link into the dependency check, and for a private repo, connect GitHub.
