A report-writing skill for turning verified open-source package vulnerabilities into submission-ready reports. VulDB is a public database of software vulnerabilities, while a CVE is a standard identifier for one.

Preparing VulDB reports, CVE requests, and related GHSA, OSV, or standalone security advisories for packages in ecosystems such as npm, Python, Go, Rust, Java, and others.

It removes the need to assemble the same technical details and reporting structure by hand for different package ecosystems. It uses finding evidence and verification information when available.

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	$0.00185	$0.03397
Opus 5	$0.00093	$0.01699
Sonnet 5	$0.00037	$0.00679
Haiku 4.5	$0.00018	$0.00340

Security

Grade A, and why

omv-report 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 11d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/check_output.py, scripts/render_template.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

VulDB Report Generator

References

Load these when needed — do not load all at once:

references/ecosystems.md — vendor naming rules, version verification commands, duplicate CVE search databases, CWE→Class mapping. Read when ecosystem-specific details are needed.
references/shared/cvss-builder.md — metric-by-metric CVSS v3.1 decision table with common vector combinations. Read when computing the CVSS score.
contracts/evidence.v1.yaml — structured input contract from omv-find; read when the user provides a handoff packet or asks to continue from finder results.
contracts/verification.v1.yaml — adversarial review sidecar. Read when .omv/verifications/<id>.yaml exists or the user asks for a high-confidence report.
contracts/source-ref.v1.yaml — optional local source identity sidecar. Read when .omv/sources/<id>.yaml exists; a locator is recorded input, not proof of remote authenticity.
contracts/report-provenance.v1.yaml — generated report input manifest shape used by omv report provenance.
references/report-templates.md — reusable VulDB, GHSA, OSV, and standalone Markdown advisory templates. Read when the user requests a specific report format.
references/examples/xss-npm.md — complete filled report for a click-triggered XSS in an npm package.
references/examples/path-traversal-go.md — complete filled report for an unauthenticated path traversal in a Go module.
references/examples/prototype-pollution-npm.md — filled report for prototype pollution in an npm package.
references/examples/redos-python.md — filled report for ReDoS in a Python package.

HARD-GATE: verification before submission-ready claims

NO submission-ready VulDB / CVE / GHSA / OSV prose WITHOUT fresh gate evidence:
  1. omv findings validate <id> OK (when CLI available)
  2. status: confirmed
  3. submissionScore ≥ 75
  4. omv review <id> --strict → ready   (or user explicitly asks for triage draft only)

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.
