• compare_buildsCompare Builds

  Compare two loaded Next.js builds and show which routes and chunks grew or shrank the most.

• explain_growthExplain Growth

  Identify which routes and chunks are responsible for bundle size growth between two loaded builds. Returns severity-ranked route findings, the top growing chunks, and an overall regression summary.

• explain_shared_chunksExplain Shared Chunks

  Show which npm packages and app code dominate the shared chunks loaded by many routes, to identify what bloats common bundles. Each package reports its unminified webpack module size, its share of the chunk's module bytes, and that share applied to the chunk's emitted size. Requires load_build_stats and load_webpack_stats first.

• find_duplicatesFind Duplicate Packages

  Find npm packages whose code is bundled into more than one chunk, wasting bytes, ranked by wasted bytes. Requires load_webpack_stats first.

• get_largest_routesGet Largest Routes

  Rank the heaviest user-facing routes in a loaded Next.js build by emitted chunk bytes.

• get_shared_chunksGet Shared Chunks

  Rank the heaviest shared chunks in a loaded Next.js build and show which routes depend on them.

• how_to_collect_statsHow To Collect Webpack Stats

  Explain how to generate the webpack stats file (.next/stats.json) required by the bundle attribution tools. Choose manual (a recipe you apply yourself) or automatic (an action plan Copilot executes).

• load_build_statsLoad Build Stats

  Parse a Next.js .next directory and load route and chunk footprint data for later analysis.

• load_webpack_statsLoad Webpack Stats

  Parse the webpack module stats file (.next/stats.json) and link it to a build loaded with load_build_stats. Unlocks the stats-powered tools: suggest_optimizations (enriched), find_duplicates, explain_shared_chunks, and trace_import.

• suggest_optimizationsSuggest Optimizations

  Aggregate route, chunk, and (when loaded) webpack-stats evidence into severity-ranked, evidence-backed bundle optimizations tied to concrete Next.js actions. Every suggestion is sized in emitted on-disk bytes. Works on manifests alone; load_webpack_stats first for dedupe, shared-chunk, and package-import suggestions.

• trace_importTrace Import

  Explain why a module is bundled by tracing its import chain from an entry point to the module. moduleSizeBytes is the unminified webpack module size, not emitted chunk size. Requires load_webpack_stats first.
