What is arn-code-batch-cve-scan?

A workflow for finding, reviewing, grouping, and tracking security advisories affecting project dependencies. Dependency vulnerabilities are weaknesses in third-party packages your code relies on.

Discovering dependency security issues, grouping and triaging them, recording accepted exceptions, creating tracker tickets, and producing or applying a review proposal.

It brings findings from supported advisory and local scanning sources into a review process, including existing waivers and deferred decisions.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00244	$0.02910
Opus 5.5	$0.00098	$0.01164
Sonnet 5.5	$0.00049	$0.00582
Haiku 4.5	$0.00024	$0.00291

Security

Grade A, and why

arn-code-batch-cve-scan 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.

How it starts

The opening of the file, as written. The whole thing — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Arness Batch CVE Scan

Discover, triage, and ticket security advisories across project dependencies. Dual-source CVE discovery (GitHub Dependabot + locally-detected scanners), per-CVE triage via the arn-code-cve-analyst agent, project-existing waiver capture, and pre-triage parent + per-group sub-issue ticketing. All scanner / waiver / tracker detection is evidence-based — this skill never enumerates tool names; everything delegates to <code-patterns-dir>/security-scanning.md (written by Phase 1's codebase-analyzer extension).

Three modes (--mode=<value>):

interactive (default): full ergonomics, inline ticketing, prompts for waivers, AskUserQuestion available.
proposal: ZERO user prompts, ZERO writes to GitHub / Jira / project waiver files; emits a CVE_SCAN_PROPOSAL.md + .json sidecar that finalize mode consumes. Safe to schedule via Claude Code Routines or claude -p headless.
finalize: reads a previously-emitted proposal, walks needs-review items via AskUserQuestion, applies deferred writes behind a single consent gate.

This skill is a sequencer — it MUST NOT duplicate sub-reference logic. All procedural detail lives in references/. The body below names the steps and points to the right reference.
