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 | $0.00065 | $0.00793 |
| Opus 5 | $0.00032 | $0.00396 |
| Sonnet 5 | $0.00013 | $0.00159 |
| Haiku 4.5 | $0.00006 | $0.00079 |
Grade A, and why
docker-specialist 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 8d 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.

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

Docker Specialist
Você reduz imagem, acelera build e fecha brecha.
Portão de segurança
Leitura livre. build, run, push, rm exigem confirmação —
docker system prune é destrutivo.
Otimização — na ordem que rende
| # | Técnica | Ganho típico |
|---|---|---|
| 1 | Multi-stage — build separado do runtime | o maior de todos |
| 2 | Ordem das camadas — dependência antes do código | cache aproveitado |
| 3 | Base slim/alpine (cuidado com glibc/musl) | 100s de MB |
| 4 | .dockerignore |
build context menor |
| 5 | --no-install-recommends, limpar apt lists |
dezenas de MB |
| 6 | Um RUN para instalar+limpar |
evita camada com lixo |
Camada só cresce: RUN apt install seguido de RUN apt clean em linhas
separadas não reduz nada — o lixo já está na camada anterior.
Padrão multi-stage
FROM node:20-slim AS build
WORKDIR /app
COPY package*.json ./ # dependência primeiro: cache
RUN npm ci
COPY . .
RUN npm run build
FROM node:20-slim
WORKDIR /app
RUN useradd -r -u 1001 app # não rode como root
COPY --from=build --chown=app /app/dist ./dist
COPY --from=build --chown=app /app/node_modules ./node_modules
USER app
HEALTHCHECK CMD curl -f http://localhost:3000/health || exit 1
CMD ["node","dist/main.js"]

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.
- 8d ago First seen · 82 lines · 65 tokens per session scan A 8ca842d94a53
docker-specialist is a skill published in the GitHub repository pwdev-solucoes/pwdev-claude-marketplace (2 stars, last pushed yesterday), licensed Apache-2.0. It adds 65 tokens to every session and 793 once invoked, about $0.0003 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 2026-09-03.
