What is oci-cve-checker?

A comparison tool for checking the security vulnerabilities, called CVEs, in two OCI container images. OCI is a standard format for packaging and running containers.

It helps review security differences between a base container image and a target image.

It shows which known vulnerabilities were fixed and which new ones appeared when an image changed.

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	$0.00029	$0.01571
Opus 5	$0.00015	$0.00785
Sonnet 5	$0.00006	$0.00314
Haiku 4.5	$0.00003	$0.00157

Security

Grade A, and why

oci-cve-checker 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 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/check_cves.sh, scripts/manage_deps.sh), 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.

OCI CVE Checker

This skill compares CVE vulnerabilities between two OCI container images and generates detailed reports showing which CVEs were fixed and which new CVEs were introduced.

Instructions

When a user asks to compare CVEs between container images or analyze security differences:

Check and install required dependencies:
```
./scripts/manage_deps.sh
```
This script checks for trivy, jq, and skopeo, and automatically installs any missing tools to a temporary directory if needed.

Run the CVE comparison script with two container image references:

./scripts/check_cves.sh <base_image> <target_image> [output_directory]

Analyze the generated output files:

Output Files

The script generates the following files in the output directory (default: ./cve-reports/):
- fixed_cves.txt: CVEs that existed in the base image but are fixed in the target image
- new_cves.txt: New CVEs that appear in the target image but weren't in the base image
- common_cves.txt: CVEs that exist in both images
- summary.txt: High-level summary with counts and statistics
- <image_name>_<digest>.json: Complete vulnerability scans for each image (filenames include image name and first 12 characters of digest, e.g., python-3.11_a1b2c3d4e5f6.json)
Interpret the results for the user:

Fixed CVEs Analysis
- Count of CVEs resolved between versions
- Severity breakdown of fixed vulnerabilities
- Notable security improvements
- Packages that were updated to fix vulnerabilities
New CVEs Analysis
- Count of newly introduced CVEs
- Severity assessment of new vulnerabilities
- Risk evaluation for production deployment
- Packages introducing new vulnerabilities
- Recommendations for mitigation
Overall Security Posture
- Net change in vulnerability count
- Severity trends (more/fewer critical CVEs)
- Recommendation on whether to upgrade
- Additional security considerations

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
