Practical patterns to dramatically reduce frontend bundle size: icon manifests, named imports, dynamic imports, and CI size checks.
This skill documents concrete techniques to reduce frontend bundle size and keep builds within a performance budget. It covers a proven icon-manifest approach to avoid wildcard icon imports, tree-shaking strategies (named imports), dynamic imports for heavy components, route/code splitting, size-limit enforcement, and CI integration for automated checks. The guide includes code snippets, build hooks, and a recommended optimization workflow.
Use this skill when auditing or reducing a web app's client-side bundle size — for instance before production deploys, when adding a large dependency, or when investigating unexpectedly large chunks in bundle analysis. It also serves as a checklist for CI gating and pre-merge reviews.
Front-end focused agents or developer tools that can inspect code and suggest changes (Claude Code, Copilot-style tools, local CI automation).
A well-written frontend bundle optimization skill documenting how one project achieved 90% bundle reduction. Covers icon manifests, tree-shaking, dynamic imports, bundle analysis, and size-limit CI checks. No bundled scripts — purely instructional. Comprehensive code examples with good/bad patterns, though closing code blocks have a minor formatting quirk (typescript tag). Practical for Next.js developers but not unique.
Monolithic SKILL.md with no scripts/, references/, or separation of concerns. Frontmatter is minimal (name + description only, no triggers/metadata). Content quality is good — clear examples with before/after patterns — but architecture follows none of the AgentSkill conventions. The dangerouslySetInnerHTML usage pattern is worth flagging as a security consideration even though the skill itself isn't malicious.
