Phy Lock File Auditorv1.0.3

Engineering teams running a multi-package npm/yarn monorepo add a lockfile freshness gate to GitHub Actions so every PR that edits package.json without regenerating package-lock.json is blocked. The skill detects drift, phantom dependencies, and integrity hash anomalies before merge, catching tampering that Snyk and Dependabot typically ignore. Result: fewer accidental dependency injections reaching main.

Maintainers of popular Python or Rust libraries run the auditor before tagging a release to verify poetry.lock and Cargo.lock integrity. Phantom entries and yanked upstream versions are flagged locally without any external API call, preserving air-gapped build environments. This protects downstream consumers from a compromised transitive dependency.

A financial services firm acquiring a startup runs the lockfile auditor across the target's JavaScript and Go repositories as part of technical due diligence. Duplicate packages pinned at conflicting versions and missing SHA-512 hashes surface hidden maintenance debt and potential supply-chain risk. Findings feed directly into the deal's risk register.

Security engineers generate recurring lockfile audit reports to satisfy control requirements around third-party component integrity. The tool's deterministic, offline analysis produces stable evidence artifacts that auditors accept without needing live package registry access. Integrity hash verification maps directly to tamper-evidence controls.

When a developer notices unusually long install times or unexpected network egress, the incident response team runs this auditor on the affected repo to check for swapped integrity hashes and phantom entries. It quickly distinguishes a stale lockfile from a malicious injection. The output guides whether to rotate credentials or roll back dependencies.

The core local lockfile audit remains free and open-source to drive adoption among individual developers and small teams. Paid tiers add hosted CI runners, organization-wide dashboards aggregating audit results, and policy-as-code enforcement across many repositories. This mirrors the model used by tools like Snyk and Socket.dev.

The auditor is packaged as a native integration module inside existing SAST/SCA platforms (e.g., GitHub Advanced Security, GitLab Ultimate, Checkmarx). Customers activate it as a premium scanning category alongside standard vulnerability scanning. Revenue comes from platform vendors licensing the engine and from enterprise upsells.

A services-led offering where security consultants use the lockfile auditor as a core diagnostic tool during dependency risk assessments, M&A technical due diligence, and post-incident investigations. Deliverables include prioritized remediation reports and lockfile hygiene playbooks. Recurring retainers provide predictable revenue.
