Webpack Plugin Authoring is an agent skill from pproenca/dot-skills. Writing webpack 5 plugins — hook selection (compiler vs compilation, tap vs tapAsync, processAssets stages), the asset pipeline (emitAsset, source classes, info metadata, source maps), watch-mode and persistent caching (file/context/missing/buildDependencies), plugin lifecycle (constructor purity, multi-compiler isolation, shutdown cleanup), schema-utils validation, WebpackError reporting, jest-worker parallelism, and compatibility patterns (compiler.webpack namespace, peerDependencies, getCompilationHooks…
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 51 other files, including reference files and assets (for example `AGENTS.md`, `assets/templates/_template.md` and `metadata.json`).
It sits in Testing & QA, covering Game assets and audio, Caching and Unit testing. It works with webpack, Next.js and Jest. The repository describes itself as: A collection of AI agent skills following the Agent Skills open format. The licence is MIT.
8 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit cf93c57. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Webpack Plugin Authoring loads about 2.7k tokens when it runs, and up to ~41k if it reads all its reference files. Until then it costs about 246 tokens; SKILL.md has 679 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/webpack-plugin-authoring/SKILL.md (or your agent's skills folder). This skill also uses 48 other files; get the full folder from GitHub.Comprehensive guide for writing correct, performant webpack 5 plugins. Contains 44 rules across 8 categories (8 hook + 7 asset + 5 cache + 5 life + 4 schema + 5 diag + 5 perf + 5 compat = 44), ordered by the authoring lifecycle: hook choice is the foundation, then asset manipulation, then caching/watch-mode correctness, then lifecycle hygiene, then user-facing concerns (schema validation, error reporting), then performance, then packaging.
Patterns are derived from webpack/webpack, the webpack-contrib plugin suite (mini-css-extract, terser, compression, copy, css-minimizer), and Next.js's webpack integration in vercel/next.js.
Reference these rules whenever:

Writing webpack 5 plugins — hook selection (compiler vs compilation, tap vs tapAsync, processAssets stages), the asset pipeline (emitAsset, source classes, info metadata, source maps), watch-mode…. Webpack Plugin Authoring is an agent skill from pproenca/dot-skills.
Webpack Plugin Authoring fits situations like: debugging webpack 5 plugins — even if the user doesnt explicitly mention best practices — anytime an apply(compiler) method is being written; hooks are being tapped; A plugin imports from webpack-sources; the rules in this skill apply.
Run `npx skills add pproenca/dot-skills --skill webpack-plugin-authoring -a claude-code`. Or copy the skill folder (skills/.experimental/webpack-plugin-authoring in pproenca/dot-skills) into .claude/skills/webpack-plugin-authoring in your project. Claude Code loads it when a task matches its description.
Run `npx skills add pproenca/dot-skills --skill webpack-plugin-authoring -a codex`. Or copy the skill folder (skills/.experimental/webpack-plugin-authoring in pproenca/dot-skills) into .agents/skills/webpack-plugin-authoring in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add pproenca/dot-skills --skill webpack-plugin-authoring -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/webpack-plugin-authoring, .gemini/skills/webpack-plugin-authoring, .github/skills/webpack-plugin-authoring and .opencode/skills/webpack-plugin-authoring in your project.
SKILL.md names no scripts, command-line tools or credentials: Webpack Plugin Authoring is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Webpack Plugin Authoring is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.7k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 38k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Webpack Plugin Authoring: Menu Testing Ssr (asmyshlyaev177/react-horizontal-scrolling-menu, 790 stars), Senior QA (alirezarezvani/claude-skills, 28k stars), Tech Trend Watch (mizchi/skills, 356 stars) and Senior QA (borghei/Claude-Skills, 874 stars).
