Servable tools is a utility that builds a protocol's manifest and documents it.

    })
    comparisons.push(comparison)
  }

  const problematic = comparisons.filter(a => {
    const {
      highestVersion,
      lowestCompatibleVersion,
      lowestVersion
    } = a

    if (semver.lt(lowestVersion.value, lowestCompatibleVersion.value)) {
