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.
npx agentmods add instructions/ivanshtokov/copilot-kit/dockergit clone --depth 1 https://github.com/ivanshtokov/copilot-kitWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00313 | $0.00313 |
| Opus 5 | $0.00156 | $0.00156 |
| Sonnet 5 | $0.00063 | $0.00063 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
copilot-kit docker.instructions.md 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 yesterday.
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.

📋 Dockerfile Best Practices
Multi-Stage Builds
# Build stage
FROM node:18-alpine AS build
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build
# Production stage
FROM node:18-alpine AS production
WORKDIR /app
COPY --from=build /app/dist ./dist
COPY --from=build /app/node_modules ./node_modules
USER node
EXPOSE 3000
CMD ["node", "dist/index.js"]
Layer Caching
- Copy dependency files first (
package.json) - Install dependencies
- Copy source code last
- Minimize layers (combine RUN commands)
🔐 Security
- Always use non-root user (
USER node) - Use specific version tags, not
latest - Don't store secrets in images
- Use multi-stage to exclude build tools
📦 .dockerignore
node_modules
.git
.env
*.log
dist
coverage
🔧 Docker Compose
- Use named volumes for persistence
- Set resource limits
- Use health checks
- Separate networks for frontend/backend
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.

copilot-kit docker.instructions.md is an instructions file published in the GitHub repository ivanshtokov/copilot-kit (2 stars, last pushed 7mo ago), licensed MIT. It adds 313 tokens to every session, about $0.0016 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 2026-08-31.
