Sample Agent Skills for Builders is a collection of reusable skills that extend AI coding agents with AWS, CDK, security, testing, and engineering workflows. Developers can install the skills for practical AWS development tasks or use the repository as a model for creating their own agent skills. The catalogue entries are skills and instructions from this collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00044 | $0.00583 |
| Opus 5 | $0.00022 | $0.00292 |
| Sonnet 5 | $0.00009 | $0.00117 |
| Haiku 4.5 | $0.00004 | $0.00058 |
Grade A, and why
security-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 6d 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Security Scan
Comprehensive AWS CDK project security and compliance scanning with multi-tool analysis.
When to Apply
Reference this skill when:
- Running security audits on CDK projects
- Checking license compliance
- Scanning container images for vulnerabilities
- Running aggregated SAST/IaC/secret analysis (via ASH)
- Generating security reports for review
How It Works
IMPORTANT: All 9 steps are mandatory. Do not skip steps regardless of time constraints.
- Architecture Diagram - Capture system architecture
- CDK Synthesis - Generate CloudFormation templates
- Viperlight Scan - Code security analysis
- License Check - Dependency license compliance
- Trivy Scan - Container vulnerability scanning
- ASH Scan - Automated Security Helper (aggregated SAST/IaC/secret scanners)
- Deployment Verification - Validate deployment readiness
- Summary Report - Generate findings summary
- HTML Report - Create visual report
Prerequisites
- AWS CDK project
- Viperlight CLI installed
- Trivy CLI installed
- ASH (Automated Security Helper) - installed via
uvxfrom https://github.com/awslabs/automated-security-helper - Docker (required for ASH container mode)
Usage
# Run security scan
"Run security scan on my CDK project"
"Check this project for vulnerabilities"
"Generate security compliance report"
Output
Results saved to security-scan-results/{TIMESTAMP}/:
- Raw scan outputs per tool
clean-results/- Parsed findingssecurity-report.html- Visual report
Enforcement Rules
- Execute ALL scan commands (no skipping)
- Fix issues found (don't just comment them)
- Non-interactive execution only
- Continue pipeline on individual step failures

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.

security-scan is a skill published in the GitHub repository aws-samples/sample-agent-skills-for-builders (47 stars, last pushed 9d ago), licensed Apache-2.0. It adds 44 tokens to every session and 583 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
