Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00067 | $0.02558 |
| Opus 5.5 | $0.00027 | $0.01023 |
| Sonnet 5.5 | $0.00013 | $0.00512 |
| Haiku 4.5 | $0.00007 | $0.00256 |
Grade B, and why
containers-orchestration scanned grade B with 2 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 1mo 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.
Recursive force deletemediumDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
&& rm -rf /var/lib/apt/lists/* Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Containers & Orchestration
Guiding Principles
- Security First: Non-root users, minimal base images, vulnerability scanning
- Efficiency: Multi-stage builds, layer optimization, build cache
- Reproducibility: Pin versions, explicit dependencies, deterministic builds
- Observability: Health checks, proper logging, metrics endpoints
Quick Reference
| Aspect | Standard |
|---|---|
| Base Images | Official image; pin the immutable digest for production |
| Multi-Stage | Required for compiled languages (Go, Rust, C++) |
| User | Run as non-root (use USER node or create user) |
| Health Checks | Include a meaningful HEALTHCHECK when the runtime exposes one |
| Scanning | Registry-native scanning gates (JFrog Xray / AWS ECR enhanced scanning) |
| Signing | Sign images with Sigstore/Cosign or Notation |
Dockerfile Best Practices
Use Official, Minimal Base Images
# ✅ GOOD - Official, minimal, secure
FROM python:3.14-slim
FROM node:20-alpine
# ⭐ EXCELLENT - Distroless for production
FROM gcr.io/distroless/python3-debian12
FROM gcr.io/distroless/nodejs20-debian12
# ❌ AVOID - Large, unnecessary packages
FROM ubuntu:latest
Pin Versions Explicitly
For production, pin the immutable digest (image:tag@sha256:digest) and use dependency automation for reviewed digest updates. The tag examples below are for readability and local development.
# ✅ GOOD - Explicit version pinning
FROM python:3.14.0-slim-bookworm
FROM node:20.10.0-alpine3.19
# ❌ BAD - Unpredictable, non-reproducible
FROM python:latest
FROM node:alpine
Multi-Stage Builds
Go Example (Recommended Pattern):
# Build stage
FROM golang:1.25.0-alpine3.22 AS builder
WORKDIR /app
COPY go.mod go.sum ./
RUN go mod download
COPY . .
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o main .
# Production stage - Distroless for minimal attack surface
FROM gcr.io/distroless/static-debian12
COPY --from=builder /app/main /main
USER nonroot:nonroot
EXPOSE 8080
ENTRYPOINT ["/main"]
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.
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.

containers-orchestration is a skill published in the GitHub repository d-padmanabhan/agent-engineering-handbook (19 stars, last pushed 2d ago), licensed MIT. It adds 67 tokens to every session and 2,558 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
