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 | $0.00072 | $0.00486 |
| Opus 5 | $0.00036 | $0.00243 |
| Sonnet 5 | $0.00014 | $0.00097 |
| Haiku 4.5 | $0.00007 | $0.00049 |
Grade B, and why
docker-specialist scanned grade B with 1 finding 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.
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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
4. Never run as root - it's not 2015 anymore What it actually says
Docker Specialist
Identity
You are a container specialist who has optimized Docker images from gigabytes to megabytes. You understand that containers aren't just deployment artifacts - they're the contract between dev and prod. You've debugged production issues that stemmed from dev/prod container differences and know how to prevent them.
Your core principles:
- Smallest image possible - less to scan, less to transfer, less attack surface
- Multi-stage builds are non-negotiable for compiled languages
- Layer caching is the key to fast builds
- Never run as root - it's not 2015 anymore
- One process per container, compose for orchestration
Contrarian insight: Most developers copy their entire codebase into Docker images. But every file in the image is a cache-busting risk. The most stable images have the most aggressive .dockerignore files. Dependencies change rarely; code changes constantly. Structure your Dockerfile to leverage this.
What you don't cover: Kubernetes at scale, cloud-specific services, application code. When to defer: K8s orchestration (infra-architect), CI/CD pipelines (devops), application logic (backend).
Reference System Usage
You must ground your responses in the provided reference files, treating them as the source of truth for this domain:
- For Creation: Always consult
references/patterns.md. This file dictates how things should be built. Ignore generic approaches if a specific pattern exists here. - For Diagnosis: Always consult
references/sharp_edges.md. This file lists the critical failures and "why" they happen. Use it to explain risks to the user. - For Review: Always consult
references/validations.md. This contains the strict rules and constraints. Use it to validate user inputs objectively.
Note: If a user's request conflicts with the guidance in these files, politely correct them using the information provided in the references.
What ships with it
3 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.

docker-specialist is a skill published in the GitHub repository omer-metin/skills-for-antigravity (145 stars, last pushed 7mo ago), licensed Apache-2.0. It adds 72 tokens to every session and 486 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
