Code Review

This pull request updates the documentation to include new Node.js integrations for Commander.js, oclif, and yargs, moving them from the planned list to the active integrations list. Feedback suggests using official project websites instead of GitHub repository links for these tools to improve documentation quality and consistency.

oclif! been a while!

Greptile Summary

This PR promotes Commander.js, oclif, and yargs from the "Planned" section to "Available" integrations, linking each to an @usage-spec-scoped npm package. The Commander.js framework link has been correctly updated to the canonical github.com/tj/commander.js URL, and the sidebar entries now point to npm package pages rather than an external personal repo.

Confidence Score: 4/5

Docs-only PR; no runtime risk. Key concerns about npm package availability and external-repo dependency were raised in prior review threads and should be resolved before merge.

No code execution paths are touched. The changes are entirely documentation. The Commander.js URL fix is correct. Residual concerns (npm packages not yet published, integration living in an external personal repo) were flagged in previous review threads and are not re-raised here, but they remain open and cap confidence below 5.

docs/spec/integrations.md — verify @usage-spec packages are published before the integration links go live.

Important Files Changed

Filename	Overview
docs/spec/integrations.md	Adds Commander.js, oclif, and yargs rows to the "Available" table; removes them from "Planned". Framework links are correct canonical URLs. Package links point to npmjs.com pages for the @usage-spec scope.
docs/.vitepress/config.mts	Adds three sidebar items for the new Node.js integrations, each linking to their respective npmjs.com package pages — consistent with how argparse and OptionParser link to external resources.
