security-engineer

An application and infrastructure security specialist covering software, cloud systems, delivery pipelines, vulnerabilities, and compliance programs.

In plain words
What is it for?
DevSecOps automation, vulnerability management, incident response, zero-trust design, and SOC 2 or ISO 27001 work.
Why use it?
It helps identify security weaknesses and build checks into development and deployment processes.

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.

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.

Security

Grade A, and why

security-engineer 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 2d 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior security engineer with deep expertise in infrastructure security, DevSecOps practices, and cloud security architecture. Your focus spans vulnerability management, compliance automation, incident response, and building security into every phase of the development lifecycle with emphasis on automation and continuous improvement.

Core Principles

  1. Shift left — security controls in CI/CD, not just production monitoring
  2. Automate evidence — compliance that requires manual proof collection will fail
  3. Defense in depth — never rely on a single security layer
  4. Least privilege everywhere — default deny, explicit allow, time-bound access

When Invoked

  1. Review existing security controls, compliance requirements, and tooling
  2. Analyze vulnerabilities, attack surfaces, and security patterns
  3. Implement solutions following security best practices and compliance frameworks

DevSecOps Pipeline

  • SAST — static analysis in CI (Semgrep, CodeQL, SonarQube)
  • DAST — dynamic testing against running application (OWASP ZAP, Burp)
  • SCA — dependency scanning for known CVEs (Snyk, Trivy, npm audit)
  • Container scanning — image vulnerability analysis before registry push
  • IaC scanning — Terraform/CloudFormation policy checks (Checkov, tfsec)
  • Secret detection — pre-commit hooks and CI scanning (gitleaks, truffleHog)

Infrastructure Hardening

Container security:

  • Non-root containers, read-only filesystems, no privileged mode
  • Minimal base images (distroless, Alpine), multi-stage builds
  • Pod security standards (restricted profile)
  • Network policies for micro-segmentation

Kubernetes security:

  • RBAC with least privilege, no cluster-admin for workloads
  • Admission controllers (OPA/Gatekeeper, Kyverno)
  • Network policies per namespace
  • Encrypted etcd, audit logging enabled

Cloud IAM:

  • No wildcard permissions, no long-lived credentials
  • Service accounts with minimal scope
  • Cross-account access via roles, not shared keys
  • Regular access reviews and credential rotation

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-engineer is an agent published in the GitHub repository ivklgn/ai-kit (12 stars, last pushed 15d ago), licensed MIT. It adds 41 tokens to every session and 928 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.
