# package.json Scripts Auditor
You review the `scripts` block of a Node.js `package.json` and explain what each script does, which ones are risky, and how to make the set clearer and more portable. You cover two audiences: maintainers tidying their own project, and reviewers checking whether a dependency or PR runs anything dangerous at install time. You never run the scripts yourself; you read them.
## Files in this skill
- `scripts/audit_scripts.py` - reads a package.json and reports findings with severity (high, medium, low, info) and a suggested fix (Python 3 standard library only)
- `references/script-conventions.md` - standard script names, lifecycle hooks, naming, and portability conventions
- `references/dangerous-patterns.md` - patterns that deserve a closer look, why they matter, and safer alternatives
- `templates/audit-report.md` - the report shape to return
- `examples/package.json` - a deliberately messy example to practice on
## Workflow
### 1. Collect context
Ask for the full `package.json` (not only `scripts`, since `name`, `private`, `bin`, `workspaces`, and `packageManager` matter), and whether this is the user's own project or a third-party package. Ask which OS the team uses (Windows support changes portability advice).
### 2. Run the auditor
```
python3 scripts/audit_scripts.py path/to/package.json
python3 scripts/audit_scripts.py --json path/to/package.json
python3 scripts/audit_scripts.py --self-test
```
Exit code 0 = no high findings, 1 = at least one high finding, 2 = file error.
### 3. Review manually
The script is pattern-based. Also read each script yourself and check:
- Lifecycle hooks (`preinstall`, `install`, `postinstall`, `prepare`) run automatically for consumers; any network call or file write outside the project there is a red flag.
- Scripts that call other files (`node scripts/setup.js`, `sh ./build.sh`): ask to see those files before calling the package safe.
- Obfuscation (base64, hex strings, `eval`, `node -e` with long one-liners) deserves high suspicion.
### 4. Recommend
Use `references/script-conventions.md` and `references/dangerous-patterns.md` to propose concrete replacements: `rimraf` or `del-cli` instead of `rm -rf`, `cross-env` instead of `VAR=value cmd`, pinned `npx pkg@1.2.3`, `prepublishOnly` running tests, and grouped names like `lint:js`, `test:unit`.
### 5. Report
Fill `templates/audit-report.md`: verdict, findings table, a rewritten `scripts` block, and follow-up questions.
## Rules
- Rate severity by impact: anything that can run remote code or delete files outside the project on install is high.
- Do not accuse authors of malice; describe the behavior and the risk.
- Keep the user's existing script names when renaming would break CI, and say which CI files would need updating if you do suggest a rename.
- Suggest `npm install --ignore-scripts` for auditing untrusted packages, and `npm config set ignore-scripts true` only with the trade-offs explained.
FILE:references/dangerous-patterns.md
# Dangerous and Risky Script Patterns
| Pattern | Example | Why it matters | Safer alternative | Severity |
|---|---|---|---|---|
| Remote script piped to a shell | `curl -fsSL https://x.sh \| sh` | Runs whatever the server returns, unpinned and unverified | Vendor the script, pin by checksum, or use a published package | high |
| Network fetch in install hooks | `"postinstall": "node download.js"` / `wget` | Runs on every consumer's machine at install time | Ship artifacts in the package, or make the step opt-in | high |
| Recursive delete of broad paths | `rm -rf /`, `rm -rf ~`, `rm -rf $DIR/` with unset var | Can wipe data outside the project | `rimraf dist`, explicit relative paths | high |
| `sudo` | `sudo npm i -g x` | Escalates privileges from a script | Never require root in scripts; document manual steps | high |
| `eval` / encoded payloads | `eval "$(echo ... \| base64 -d)"`, `node -e "...Buffer.from('..','base64')"` | Hides what runs | Plain, readable commands in files | high |
| Inline secrets | `API_TOKEN=abc123 node deploy.js` | Leaks in git history and CI logs | Environment variables from a secret store or `.env` not committed | high |
| World-writable permissions | `chmod 777`, `chmod -R a+w` | Lets any user modify files | Minimal permissions (`chmod +x file`) | medium |
| Skipping safety checks | `git commit --no-verify`, `npm publish --force`, `--unsafe-perm` | Bypasses hooks and protections | Fix the failing check instead | medium |
| Unpinned `npx` / `dlx` | `npx create-thing` | Downloads and runs the latest version at run time | `npx create-thing@3.2.1` or add as devDependency | medium |
| Global installs in scripts | `npm i -g typescript` | Changes the user's machine; versions drift | devDependency + local bin | medium |
| Plain HTTP URLs | `curl http://...` | Can be tampered with in transit | HTTPS | medium |
| `git push` / `npm publish` in hooks | `"postbuild": "npm publish"` | Accidental releases | Explicit `release` script run by CI | medium |
| Non-portable shell syntax | `NODE_ENV=prod`, `export`, `cp -r` | Breaks on Windows | `cross-env`, `cpy-cli`, Node scripts | low |
| Placeholder test | `echo "Error: no test specified" && exit 1` | CI fails or tests silently missing | Real test runner | low |
| Very long one-liners | > 200 chars | Hard to review; hides risk | Move to a script file | low |
## Review tips
- For third-party packages: inspect with `npm pack <pkg>` and read the tarball, or install with `--ignore-scripts` first.
- Follow file references: `node scripts/postinstall.js` is only as safe as that file.
- Watch for `prepare` in git dependencies: it runs when installing from a git URL.
FILE:references/script-conventions.md
# npm Script Conventions
## Standard names
| Script | Purpose | Run with |
|---|---|---|
| `start` | Run the app in production mode | `npm start` |
| `dev` | Run with watch / hot reload | `npm run dev` |
| `build` | Produce build output | `npm run build` |
| `test` | Run the test suite (CI default) | `npm test` |
| `lint` | Static checks | `npm run lint` |
| `format` | Apply formatter | `npm run format` |
| `typecheck` | `tsc --noEmit` or similar | `npm run typecheck` |
| `clean` | Remove build artifacts | `npm run clean` |
Use a colon to group variants: `test:unit`, `test:e2e`, `lint:css`, `build:docs`. Use `npm-run-all` / `run-p` / `run-s`, or `npm run a && npm run b`, to compose them.
## Lifecycle hooks
| Hook | Runs when | Notes |
|---|---|---|
| `preinstall`, `install`, `postinstall` | Your package is installed, including as a dependency | Runs on every consumer's machine. Keep empty unless compiling native code. |
| `prepare` | After local `npm install` and before `npm publish`/`npm pack`; also for git dependencies | Good for building or setting up git hooks (e.g. `husky`). |
| `prepublishOnly` | Only before `npm publish` | Put `npm test && npm run build` here. |
| `prepack`, `postpack` | Around `npm pack` / publish | |
| `preX` / `postX` | Automatically before/after any script `X` | Can surprise readers; prefer explicit chaining. pnpm does not run them by default. |
## Portability
- Windows `cmd.exe` does not understand `VAR=value cmd`, `export`, `rm -rf`, `cp -r`, `&` backgrounding, single quotes, or `$VAR`. Use `cross-env`, `rimraf`, `cpy-cli`, `concurrently`, and Node scripts.
- `&&` works in both shells; `;` does not run the same way in `cmd.exe`.
- Prefer local binaries (from `devDependencies`) over globally installed ones; npm adds `node_modules/.bin` to PATH inside scripts.
## Clarity
- One job per script; move long logic (> ~120 characters) into `scripts/*.js` or `*.mjs` files.
- Avoid names that shadow npm commands or each other (`install`, `publish`, `test2`).
- Replace the default `echo "Error: no test specified" && exit 1` with a real test command or remove it.
- Document unusual scripts in the README.
- Set `"private": true` for apps that must never be published.

# package.json Scripts Audit
**Package:** `<name>@<version>` | **Owner:** own project / third-party | **Private:** yes/no
**Verdict:** Safe / Needs changes / Do not install until reviewed
**Counts:** high `<n>`, medium `<n>`, low `<n>`, info `<n>`
## Script inventory
| Script | What it does (plain words) | Runs automatically? |
|---|---|---|
| `build` | | no |
| `postinstall` | | yes, on every install |

I want something genuinely mesmerizing. A tiny, self-contained world that feels alive. The kind of scene viewers can stare at for hours and continually discover little details they hadn't noticed before. ## Creative Direction Imagine a forgotten corner of a sprawling futuristic megacity, sometime around 2089. It's 2:37 AM. Rain has been falling for days. The streets are soaked, the buildings are ancient and overcrowded, and the city glows with a thousand little signs of life. The atmosphere should feel simultaneously melancholic, cozy, mysterious, and strangely comforting. This is a world where technology has taken over everything, but human warmth still survives in little pockets. Think cinematic cyberpunk meets the intimate charm of meticulously crafted pixel-art environments. Don't settle for a generic neon skyline. Create a place with personality, history, visual storytelling, and a strong sense of depth. ## Visual Composition Design a beautiful, layered environment with a compelling focal point and plenty of environmental storytelling. Consider elements such as: - A tiny apartment or rooftop hideaway overlooking a vast, rain-drenched futuristic city. - Glowing windows revealing glimpses of other people's lives. - Holographic advertisements, animated signage, and distant traffic. - Clusters of air-conditioning units, ventilation ducts, exposed wiring, satellite dishes, and improvised technology. - Warmly illuminated vending machines, computer terminals, and mysterious electronic equipment. - Rainwater collecting in puddles and cascading from rooftops. - Distant elevated trains or flying vehicles silently moving through the mist. - Tiny human silhouettes occasionally visible behind windows. - Overgrown plants reclaiming corners of this technological world. These are creative possibilities, not a mandatory checklist. Make deliberate artistic choices. Prioritize a coherent, memorable composition over cramming everything into the frame. The scene should feel handcrafted, with exquisite attention to small details. ## Color and Lighting Build the entire visual identity around dramatic warm/cold contrast. The outside world is dominated by deep midnight blues, desaturated teals, indigo shadows, and cold cyan rain. Against this darkness, create beautiful pockets of warmth: - Rich amber light spilling from apartment windows. - Soft orange and golden illumination from lamps and electronics. - Occasional saturated magenta, electric violet, and crimson neon. - Warm reflections shimmering across cold, wet surfaces. Use lighting to tell a story. Every illuminated window should feel like a little sanctuary against the enormous, indifferent city. The overall image should be dark and atmospheric without becoming muddy or losing detail. ## Animation: Make the World Feel Alive This is absolutely critical. I don't want a static illustration with a generic rain effect. I want a living pixel-art environment with dozens of subtle, independently animated details. Build a sophisticated system of layered ambient animations: ### Weather and atmosphere - Beautiful multi-depth rainfall with varying speeds and intensities. - Occasional heavier gusts that push rain diagonally. - Thin layers of drifting fog and atmospheric haze. - Smoke rising from vents and chimneys, curling into the night. - Water dripping from ledges and splashing into puddles. - Ripples spreading across reflective surfaces. ### Lighting and electronics - Neon signs flickering irregularly, with convincing electrical behavior. - Screens cycling through mysterious data and advertisements. - Small indicator lights blinking asynchronously. - Warm interior lights gently fluctuating. - Occasional sparks from damaged electrical equipment. - Animated reflections responding to nearby light sources. ### Environmental life - Slowly rotating ventilation fans. - Distant vehicles passing behind buildings. - Tiny silhouettes moving behind illuminated windows. - Steam escaping from pipes. - Hanging cables or signs subtly swaying in the wind. - Occasional small, unexpected details that reward prolonged viewing. Every effect should have its own rhythm. Avoid synchronized, repetitive animation that makes the world feel artificial. ## Seamless Infinite Looping This scene must run beautifully for 10 hours or longer without a visible reset, jump, or discontinuity. Design every animation to be mathematically seamless or continuously procedural. Use independent animation cycles, staggered timing, seeded randomness, and layered motion to create the impression of endless organic variation. No sudden resets. No obvious looping rain textures. No visible animation seams. The scene should remain interesting over time without becoming distracting. This is lo-fi music, so the animation should be hypnotic and relaxing rather than chaotic. Reserve dramatic events for rare, carefully controlled moments. ## Pixel-Art Rendering: Non-Negotiable The visual style must be authentic, razor-sharp pixel art, not a high-resolution illustration with a pixelation filter. Technical requirements: - Internal rendering resolution: 640 × 360 - Final presentation resolution: 1920 × 1080 - Exact integer upscale: 3× - Scaling: nearest-neighbor only - Every source pixel must become a perfectly sharp 3×3 block. - Absolutely no bilinear filtering, blurry edges, antialiasing, or subpixel rendering. - No smooth vector graphics mixed into the pixel-art scene. - All effects, including particles, rain, fog, reflections, and lighting, must respect the pixel grid. - Maintain consistent pixel density across every visual layer. The result should look spectacular on a full-screen 1080p YouTube video, with beautiful, deliberately placed hard pixels. ## Technical Implementation Build this as a complete, self-contained, real-time animated experience. Use whatever rendering architecture delivers the best combination of visual quality, performance, and pixel-perfect consistency. HTML5 Canvas, WebGL, or a hybrid approach are all acceptable. Prioritize: - Smooth, efficient rendering at 1080p. - Deterministic, seamless animation. - Rich visual depth through layered parallax and atmospheric perspective. - Procedural particle systems for weather and environmental effects. - Carefully controlled lighting, blending, and reflections. - Stable performance over extremely long runtimes. - A fixed camera with no unintended movement or jitter. - Correct resizing while preserving the 16:9 composition and pixel-perfect scaling. If useful, implement the world as multiple independently animated layers, all composited at the internal resolution before the final upscale. Include a way to run the scene full-screen and hide any interface elements so it can be captured cleanly for YouTube. ## Artistic Quality Bar This should feel like an exceptional piece of animated pixel art, not a programming demonstration. Composition, atmosphere, color harmony, and environmental storytelling matter just as much as technical sophistication. Avoid generic procedural rectangles masquerading as buildings. Give the architecture intentional shapes, recognizable structures, believable construction details, and visual variety. Use foreground silhouettes, middle-ground architecture, and distant city layers to create a strong sense of scale. Every element should contribute to a cohesive world. The ultimate goal: A mesmerizing cyberpunk night scene that makes someone wish they could climb through their monitor, sit beside a warm window with a cup of coffee, and listen to the rain falling on a futuristic city that never sleeps. Make it beautiful. Make it atmospheric. Make it technically excellent. And above all, make it feel alive. Don't just describe how you would build it. Actually implement the complete working experience. Deliver the finished piece as a single standalone HTML file (all code inline, no external assets or build step) that runs by opening it in a browser.

Confidence: 0.90 - Use Playwright Test as the runner; do not mix Cypress and Playwright in one project. Confidence: 0.90 - Prefer `getByRole`, `getByLabel` and `getByTestId` over CSS or XPath selectors that break on restyles. Confidence: 0.95 - Add a stable `data-testid` only when role and label are genuinely ambiguous, and document the convention in the README.

Confidence: 0.95 - Write Workers in TypeScript with the official workers-types, and enable `strict` in `tsconfig`. Confidence: 0.90 - Keep each Worker focused on one job: edge API, rewrite, auth gate or queue consumer; split unrelated work into separate Workers.
