Automated summary
Generates a Tekton task that uses Trivy to scan a container image for critical and high vulnerabilities and fails the pipeline if any are found.
Strengths
- Automates vulnerability scanning in CI/CD pipelines.
- Leverages Trivy, a popular open-source scanner.
- Easy to plug into existing Tekton pipelines.
- Fail-fast approach for critical and high severity issues.
Limitations
- Only covers critical and high severities.
- Requires a Tekton environment to run.
- Assumes the image tag uses a short Git commit.
Use this skill when you have a Tekton-based CI/CD pipeline and want to enforce security scanning before deployment.
Do not use it if your pipeline uses a different CI/CD system (e.g., Jenkins, GitHub Actions) or if you need more granular severity control.
Security analysis
SafeThe skill merely instructs to generate a YAML file for a Tekton task using Trivy; it does not execute any commands, manipulate files, or interact with the system. There are no destructive or exfiltrating actions.

How this analysis is madeExamples
Create a Tekton task that uses Trivy to scan the container image 'my-app:1.0.0' for critical and high vulnerabilities and fail the pipeline if any are found.I have a Tekton pipeline that builds a container image. Generate a Tekton task to scan that image with Trivy and abort the pipeline on critical or high vulnerabilities. The image parameter should be passed from the previous task.name: security description: Generate Tekton Task that uses Trivy to scan generated container for vulnerabilities. metadata: version: "0.1" author: "Alex Soto" standard: "agentskills.io"

Instructions for Bob
Step 1: Generate a Tekton Task using Trivy
The task should receive as parameter the container image name. The task should only fail if the container image contains CRITICAL or HIGH vulnerabilities.
- Use the
aquasec/trivy:0.50.0container to run thetrivycommand. - The
exit-codeshould be 1 when a vulnerability is found.
The following snippet shows an example:
apiVersion: tekton.dev/v1
kind: Task
metadata:
name: trivy-scan
spec:
params:
- name: image-name
type: string
steps:
- name: scan
image: aquasec/trivy:0.50.0
script: |
trivy image --severity CRITICAL,HIGH \
--exit-code 1 \
$(params.image-name):$(git rev-parse --short HEAD)
Critical
- Use only trivy tool for vulnerabilities
From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/vulnerability-scanning-with-tekton-and-trivy-mm78nod2/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/vulnerability-scanning-with-tekton-and-trivy-mm78nod2' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/vulnerability-scanning-with-tekton-and-trivy-mm78nod2/download' --output '.skill-downloads/vulnerability-scanning-with-tekton-and-trivy-mm78nod2/SKILL.md.part' && mv '.skill-downloads/vulnerability-scanning-with-tekton-and-trivy-mm78nod2/SKILL.md.part' '.skill-downloads/vulnerability-scanning-with-tekton-and-trivy-mm78nod2/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

It does not run the skill or install its dependencies.
For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/vulnerability-scanning-with-tekton-and-trivy-mm78nod2/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
