Dependencies Audit

Dependencies Fix

Find and fix all dependency issues in $ARGUMENTS (or the root package.json if no argument is given) — vulnerabilities, outdated packages, deprecated dependencies, license problems, and supply-chain risks. This skill produces the review-packages.md artifact required by the Flows app review process.

---

Step 1 — Read and list all dependencies

# List all dependencies and devDependencies
node -e "
  const pkg = require('./package.json');
  console.log('=== Dependencies ===');
  Object.entries(pkg.dependencies || {}).forEach(([name, ver]) => console.log(name + ' @ ' + ver));
  console.log('\\n=== Dev Dependencies ===');
  Object.entries(pkg.devDependencies || {}).forEach(([name, ver]) => console.log(name + ' @ ' + ver));
"

Record the total count of dependencies and devDependencies.

---

Step 2 — Look up npm metadata and update outdated packages

For each package, gather:

• Latest version on npm
• Weekly downloads
• Last publish date
• Deprecated flag

# Batch lookup — run for each package (example for a single package)
npm view  --json 2>/dev/null | node -e "
  const data = JSON.parse(require('fs').readFileSync('/dev/stdin','utf8'));
  console.log(JSON.stringify({
    name: data.name,
    latest: data['dist-tags']?.latest,
    modified: data.time?.modified,
    deprecated: data.deprecated || false,
  }));
"

# For weekly downloads, use the npm API
curl -s "https://api.npmjs.org/downloads/point/last-week/" | node -e "
  const data = JSON.parse(require('fs').readFileSync('/dev/stdin','utf8'));
  console.log(data.downloads);
"

For efficiency, batch multiple lookups. If the project has many dependencies, use a script:

node -e "
  const { execSync } = require('child_process');
  const pkg = require('./package.json');
  const allDeps = { ...pkg.dependencies, ...pkg.devDependencies };

  for (const [name, usedVersion] of Object.entries(allDeps)) {
    try {
      const info = JSON.parse(execSync('npm view ' + name + ' --json 2>/dev/null', { encoding: 'utf8' }));
      const latest = info['dist-tags']?.latest || 'unknown';
      const modified = info.time?.modified || 'unknown';
      const deprecated = info.deprecated ? 'YES' : 'No';
      console.log([name, usedVersion, latest, modified, deprecated].join(' | '));
    } catch {
      console.log(name + ' | ' + usedVersion + ' | LOOKUP FAILED');
    }
  }
"

Fix: Update outdated packages

For each package that is >1 major version behind, update it:

pnpm update @latest

For packages that are 1+ minor versions behind, update to latest minor:

pnpm update 

After updating, run pnpm install and pnpm run build to verify nothing breaks. If a major update breaks the build, revert that specific update and note it as a manual-fix item.

---

Step 3 — Run security audit and fix vulnerabilities

# Run audit with the project's package manager
pnpm audit --json 2>/dev/null || npm audit --json 2>/dev/null

# Also run production-only audit (what ships to users)
pnpm audit --prod --json 2>/dev/null || npm audit --production --json 2>/dev/null

Parse the JSON output for:

• Severity counts (critical, high, moderate, low)
• Per-vulnerability details (package, severity, title, patched version, advisory URL)

Any package with a known CVE is an automatic Fail in the health column.

Fix: Resolve vulnerabilities

Run pnpm audit fix to auto-fix what's possible. For remaining high/critical CVEs that can't be auto-fixed, manually update the vulnerable package in package.json to the patched version and run pnpm install. If the patched version has breaking changes, apply the minimum code changes needed to adapt. If a vulnerability is in a transitive dependency, use pnpm overrides in package.json to force the patched version:

{
  "pnpm": {
    "overrides": {
      "vulnerable-package": ">=2.1.0"
    }
  }
}

After applying fixes, re-run pnpm audit to confirm the vulnerabilities are resolved. Run pnpm run build to verify nothing breaks.

---

Step 4 — Assign health scores and fix Fail-scored packages

For each package, assign a health indicator:

| Health | Criteria | |--------|----------| | Pass | >100k weekly downloads AND updated within last 12 months AND not deprecated AND version is current or near-current (within 1 major) | | Warn | 10k–100k weekly downloads OR >12 months since last publish OR >1 major version behind | | Fail | /dev/null', { encoding: 'utf8' })); const scripts = info.scripts || {}; const risky = ['preinstall', 'install', 'postinstall'].filter(s => scripts[s]); if (risky.length > 0) { console.log('INSTALL SCRIPT: ' + name + ' — ' + risky.join(', ')); } } catch {} } "

Check for packages with very few maintainers (single point of failure)

This is informational, not blocking

### Fix: Evaluate and mitigate install script risks

For each dependency with install scripts, determine if the script is legitimate (e.g., native module compilation for `sharp`, `esbuild`, `better-sqlite3`). Known build tools and native module packages are expected to have install scripts.

If the package is not a known build tool and has suspicious install scripts, replace it with a safer alternative. After replacement, run `pnpm install` and `pnpm run build` to verify.

---

## Step 6 — Check license compatibility and replace problematic packages

```bash
# List all licenses
npx license-checker --summary 2>/dev/null || node -e "
  const { execSync } = require('child_process');
  const pkg = require('./package.json');
  const allDeps = Object.keys({ ...pkg.dependencies, ...pkg.devDependencies });

  for (const name of allDeps) {
    try {
      const info = JSON.parse(execSync('npm view ' + name + ' --json 2>/dev/null', { encoding: 'utf8' }));
      console.log(name + ': ' + (info.license || 'UNKNOWN'));
    } catch {}
  }
"

Acceptable licenses for Flows apps (commercial distribution):

• MIT, Apache-2.0, BSD-2-Clause, BSD-3-Clause, ISC, 0BSD, Unlicense, CC0-1.0

Licenses that need legal review:

• GPL-2.0, GPL-3.0, LGPL-2.1, LGPL-3.0, AGPL-3.0, MPL-2.0, EUPL-1.1
• Any "UNKNOWN" or missing license

Fix: Replace packages with problematic licenses

For each package with a copyleft license (GPL, AGPL) or unknown license in production dependencies, find an MIT/Apache-2.0 licensed alternative and replace it. Update all imports across the codebase.

For devDependencies with copyleft licenses, these are lower risk but still flag for awareness.

After each replacement, run pnpm install and pnpm run build to verify.

Step 7 — Generate the review-packages.md artifact (post-fix state)

Re-run the metadata lookups after all fixes have been applied to capture the post-fix state. Then produce the output in the format required by the Flows app review process:

## Package audit: [app name]

### Dependencies

| Package | Used version | Latest | Weekly downloads | Last published | Deprecated | CVEs | Health |
| ------- | ------------ | ------ | ---------------- | -------------- | ---------- | ---- | ------ |
| react | ^18.2.0 | 18.3.1 | 25M | 2024-04-26 | No | 0 | Pass |
| some-old-lib | ^1.0.0 | 1.0.3 | 5k | 2021-03-15 | No | 0 | Fail |

### Dev Dependencies

| Package | Used version | Latest | Weekly downloads | Last published | Deprecated | CVEs | Health |
| ------- | ------------ | ------ | ---------------- | -------------- | ---------- | ---- | ------ |
| vitest | ^1.6.0 | 2.0.1 | 8M | 2024-07-01 | No | 0 | Pass |

### Security audit

| Severity | Count |
| -------- | ----- |
| Critical | 0 |
| High | 0 |
| Moderate | 0 |
| Low | 0 |

#### Vulnerabilities

| Package | Severity | Title | Patched in | Advisory |
| ------- | -------- | ----- | ---------- | -------- |
| (none found) | — | — | — | — |

### License summary

| License | Count | Packages |
| ------- | ----- | -------- |
| MIT | 45 | react, react-dom, ... |
| Apache-2.0 | 3 | ... |

### Supply-chain flags

| Package | Risk | Details |
| ------- | ---- | ------- |
| (none found) | — | — |

---

Step 8 — Report remaining issues

Summarize what was fixed and what remains:

Fixed

| Category | Count | Details | |----------|-------|---------| | Packages updated | N | list of packages and version changes | | CVEs resolved | N | list of CVEs fixed | | Deprecated deps replaced | N | old package -> new package | | License issues resolved | N | old package -> new package |

Remaining (could not auto-fix)

List only issues that could not be automatically fixed:

• Breaking changes from major updates that need manual code adaptation
• Licenses that need legal review (e.g., LGPL in transitive dependencies)
• Packages with no maintained alternative available
• Vulnerabilities with no patched version available yet

For each remaining item, explain why it could not be auto-fixed and what the app author needs to do.

---

Done

State the overall health verdict: how many Pass/Warn/Fail after fixes, how many issues were resolved, and any remaining items that need manual attention from the app author.
