description	Audit a JavaScript/TypeScript repo's npm, yarn, or pnpm configuration for supply-chain hardening: tool version, lifecycle scripts, unsafe dependency protocols, and minimum release age ≥3 days. Use when the user invokes /check-npm or asks to audit package manager security, lifecycle scripts, git dependencies, ignore-scripts, min-release-age, allow-git, approvedGitRepositories, strictDepBuilds, or blockExoticSubdeps in a Grafana plugin or JS/TS project.

npm / yarn / pnpm supply-chain audit

Read-only audit of the workspace root. Do not modify any files.

0. Detect package manager

test -f package.json || { echo "STOP: no package.json at workspace root"; exit 1; }
jq -r '.packageManager // "unset"' package.json
ls -1 yarn.lock package-lock.json pnpm-lock.yaml 2>/dev/null || true

If no package.json, stop. Priority: packageManager → lockfile → default npm.

1. Tool version

npm --version    # required ≥ 11.15.0
yarn --version   # required ≥ 4.14.0
pnpm --version   # required ≥ 11.0.0

Use semver comparison. Verify pinned packageManager meets threshold.

Manager	Minimum
npm	11.15.0
yarn	4.14.0
pnpm	11.0.0

2. Lifecycle scripts disabled

grep -E '^ignore-scripts=' .npmrc 2>/dev/null
grep -E 'enableScripts:' .yarnrc.yml 2>/dev/null
grep -E 'strictDepBuilds:|dangerouslyAllowAllBuilds:|allowBuilds:' pnpm-workspace.yaml 2>/dev/null

Manager	PASS	FAIL
npm	.npmrc has ignore-scripts=true	missing or false
yarn	enableScripts: false or key absent	enableScripts: true
pnpm ≥ 11	strictDepBuilds unset/true, dangerouslyAllowAllBuilds unset/false, and allowBuilds unset/[]	strictDepBuilds: false, dangerouslyAllowAllBuilds: true, or allowBuilds non-empty
pnpm 10	.npmrc ignore-scripts=true OR strictDepBuilds: true	neither

pnpm 11+ ignores script settings in .npmrc and package.json#pnpm. pnpm 10 / yarn edge cases: references/managers.md.

3. Unsafe dependency protocols

Registry:

grep -E '^allow-git=' .npmrc 2>/dev/null
grep -E 'approvedGitRepositories:' .yarnrc.yml 2>/dev/null
grep -E 'blockExoticSubdeps:' pnpm-workspace.yaml 2>/dev/null

Scan workspace package.json files (dependencies, devDependencies, optionalDependencies, peerDependencies). Prefer workspace-member discovery (pnpm-workspace.yaml / root workspaces / lerna / rush) per references/protocols.md, then scan only those manifests. Fallback (may overmatch non-workspace manifests):

find . -name package.json -not -path '*/node_modules/*'

Safe values only: semver range, workspace:, patch:, npm: alias to semver. Flag everything else (git URLs, tarballs, user/repo shorthand, file:, link:, exec:, …) as path → name → value (protocol).

Manager	PASS	FAIL
npm	allow-git=none or root	missing or all
yarn	approvedGitRepositories: [] or grafana-scoped list, or omitted with policy comment + clean scan	unsafe entries or broad allow-list
pnpm ≥ 11	blockExoticSubdeps unset/true	false
pnpm 10.x	blockExoticSubdeps: true	unset (default false) or false

Protocol detection order and yarn posture details: references/protocols.md.

4. Minimum release age ≥ 3 days

3 days = 4320 minutes. npm uses days; yarn and pnpm use minutes.

grep -E '^min(imum)?-release-age=' .npmrc 2>/dev/null
grep -E 'npmMinimalAgeGate:' .yarnrc.yml 2>/dev/null
grep -E 'minimumReleaseAge:|minimumReleaseAgeStrict:' pnpm-workspace.yaml 2>/dev/null

Manager	PASS	FAIL
npm	min-release-age ≥ 3	missing
yarn	npmMinimalAgeGate ≥ 4320 min	missing or below
pnpm ≥ 11	minimumReleaseAge ≥ 4320	unset (default 1440) or below
pnpm 10	minimum-release-age / minimumReleaseAge ≥ 4320	missing

Flag minimumReleaseAgeStrict: false on pnpm 11.

5. Report

#	Check	Status	Detail
0	Package manager	(npm / yarn / pnpm)	version: x.y.z (pinned: y.y.y if set)
1	Tool version ≥ threshold	PASS / FAIL	actual vs required
2	Scripts disabled	PASS / FAIL	config line or "missing"
3	Unsafe dep protocols	PASS / FAIL	registry state + flagged entries
4	Min release age ≥ 3 days	PASS / FAIL	config + value

Use PASS / FAIL only — no emojis.

For each FAIL, one paste-ready fix:

# npm — .npmrc
ignore-scripts=true
allow-git=none
min-release-age=3

# pnpm 11 — pnpm-workspace.yaml
strictDepBuilds: true
dangerouslyAllowAllBuilds: false
allowBuilds: []
minimumReleaseAge: 4320
blockExoticSubdeps: true

# yarn — .yarnrc.yml
npmMinimalAgeGate: 4320

If all PASS: "All checks passed." and stop.
