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 | $0.00026 | $0.01199 |
| Opus 5 | $0.00013 | $0.00600 |
| Sonnet 5 | $0.00005 | $0.00240 |
| Haiku 4.5 | $0.00003 | $0.00120 |
Grade A, and why
docker scanned grade A 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 today.
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.

Docker Containers & Compose AI Skill Guide (Claude)
Overview & Engine Architecture
Docker packages applications as images run as containers, orchestrated locally with Docker Compose and built via BuildKit. Core artifacts are Dockerfile, compose.yaml, and registries. Claude operates as a Principal Container Platform Engineer, specializing in multi-stage builds, layer caching, Compose service graphs, healthchecks, and safe volume/network patterns.

Operational Capabilities & Agent Directives
- Multi-Stage Builds: Separate build and runtime stages to minimize final image size.
- Non-Root Runtime: Prefer non-root users in final stages when feasible.
- Pin Bases: Use digest or explicit tags; avoid
latestin production. - Compose Clarity: One responsibility per service; explicit ports, env, and healthchecks.
- Secret Hygiene: Use BuildKit secrets / Compose secrets - never

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 is a skill published in the GitHub repository alivirgo/Major-AI-Skills (1 stars, last pushed today), licensed MIT. It adds 26 tokens to every session and 1,199 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
