It&#8217;s a single binary, works as an agent hook or a shell wrapper. It has a plugin system to customize filters per command.The idea is pretty simple: agents don&#8217;t need the full kubectl get -o yaml or any 10k-line dump to make decisions. So that lowfat sits in between, strips the noise, and passes through what matters. &#8230;<\/p>\n<p><a href=\"https:\/\/github.com\/zdk\/lowfat\">\u67e5\u770b\u539f\u6587 \u2192<\/a><\/p>\n<hr>\n<p><small>\u6765\u6e90\uff1aHacker News \u00b7 RSS \u91c7\u96c6<\/small><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hi HN, not sure if anyone would be interested, but just [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"ai_generated_summary":"","footnotes":""},"categories":[7],"tags":[],"class_list":["post-1607","post","type-post","status-publish","format-standard","hentry","category-tech"],"_links":{"self":[{"href":"https:\/\/wp.rungobag.cn\/index.php\/wp-json\/wp\/v2\/posts\/1607","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wp.rungobag.cn\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wp.rungobag.cn\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wp.rungobag.cn\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/wp.rungobag.cn\/index.php\/wp-json\/wp\/v2\/comments?post=1607"}],"version-history":[{"count":0,"href":"https:\/\/wp.rungobag.cn\/index.php\/wp-json\/wp\/v2\/posts\/1607\/revisions"}],"wp:attachment":[{"href":"https:\/\/wp.rungobag.cn\/index.php\/wp-json\/wp\/v2\/media?parent=1607"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wp.rungobag.cn\/index.php\/wp-json\/wp\/v2\/categories?post=1607"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wp.rungobag.cn\/index.php\/wp-json\/wp\/v2\/tags?post=1607"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
