angular-typechecker: Skill for Claude Code

.claude/skills/atc-use-cve-lite-cli/SKILL.md

atc-use-cve-lite-cli is a skill for Claude Code from LayZeeDK/angular-typechecker. It costs 170 tokens per session (1,239 once invoked), scanned A, original, MIT.

A dependency-vulnerability scanning workflow using OWASP cve-lite-cli and the OSV advisory database, which records known software security issues.

In plain words
What is it for?
Use it when changing package dependencies, running the required CI security check, investigating CVE or Dependabot findings, and adding package overrides to apply fixes.
Why use it?
It finds high- and critical-severity problems in locked packages before they block a pull request or merge.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

atc-use-cve-lite-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Using cve-lite-cli in angular-typechecker

OWASP cve-lite-cli (an OWASP Lab Project) is this repo's dependency vulnerability scanner. It parses the lockfile, matches packages against the OSV advisory database, and prints a copy-and-run fix plan. It runs both locally and as a required CI gate, so a finding it reports is something you have to clear before a PR can merge.

Running the scan

npm run cve-lite          # = cve-lite . --fail-on high  (the exact command CI runs)
  • Scans the root package-lock.json against OSV and exits non-zero on any high- or critical-severity advisory (--fail-on high means "at or above high"; moderate/low are reported but do not fail).
  • The cve-lite job in .github/workflows/ci.yml runs this same script and sits in the aggregate ci job's needs, so a high/critical finding blocks the merge button. main is PR-only with an empty bypass, so if the gate is stuck (an OSV.dev outage, or a new no-fix advisory), recover via the ruleset-enforcement toggle documented in AGENTS.md ("Lockout recovery"), not by weakening the gate.
  • Run it before opening a PR that touches package.json / package-lock.json so you catch a finding locally instead of in CI.

Resolving a finding

  1. Direct dependency -> cve-lite . --fix applies validated direct-dependency fixes and rescans, or bump the version yourself.
  2. Transitive dependency -> the fix is an overrides entry (npm) or a pnpm.overrides entry (pnpm). Follow the two rules below -- both were learned the hard way in this repo, and getting them wrong either breaks CI or breaks unrelated consumers.

Rule 1 -- prefer a nested, parent-scoped override; avoid global and version-keyed ones

A global "pkg": "x" override forces every copy of pkg in the tree to x. A version-keyed key ("[email protected]": "...") looks surgical but is not applied consistently across npm 10 and npm 11: npm 11 rewrites the lockfile while npm 10 does not, so npm ci fails on the Node-22 CI runner with an EUSAGE "Missing: [email protected] from lock file" error. The portable, targeted form is the foundational nested one, scoped to just the offending edge:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
