Generic Constructor-Pattern agent kit for Claude Code. Zero personal data, fully English, MIT-licensed. Contents: - 34 reusable blocks (baseline, rules, stack/deploy/domain/api/scraper) - 14 cross-project agent manifests (code/ml/infra/researcher/critic/...) - 6 portable skills (/new-agent, /research, /test-gen, /debug-deep, /pr-review, /refactor) - Rust assembler (single binary, ~500 KB) - 3 hooks (auto-reassemble, pre-commit validate, no-hand-edit) - install.sh (idempotent, cargo-builds on first run) - MIT LICENSE All 6 sanity greps pass: 0 Russian text, 0 specific project names, 0 incident numbers, 0 user paths, 0 hardcoded IPs, 0 API keys. cargo check + assemble --validate: both pass on 14 manifests.

DEPLOY — Docker
Dockerfile — multi-stage MANDATORY (build tools never ship to prod image):
FROM rust:1.80 AS builder
WORKDIR /app
COPY . .
RUN cargo build --release --bin myapp
FROM gcr.io/distroless/cc-debian12
COPY --from=builder /app/target/release/myapp /myapp
USER nonroot:nonroot
HEALTHCHECK --interval=30s --timeout=3s CMD ["/myapp", "--healthcheck"]
ENTRYPOINT ["/myapp"]
Base image: distroless (preferred, no shell — smaller attack surface) or alpine (if musl compat) or debian:slim. NEVER ubuntu:latest for prod.
File ops:
COPY— deterministic. NEVERADD(auto-extracts tars, fetches URLs — surprising behavior)..dockerignorecommitted. Includes.git,target/,node_modules/,.env*,secrets/.
Secrets:
- NEVER
ENV SECRET=...— leaks into image layers forever. - Build-time secrets via
--secret id=foo,src=./foo.txt(BuildKit). - Runtime secrets via env injection from orchestrator / docker-compose
secrets:(Swarm) / K8s Secret.
User: USER nonroot (distroless provides it) or explicit RUN useradd -u 10001 app && USER app. Running as root = CVE amplifier.
Healthcheck: MANDATORY. Orchestrator uses it for readiness/liveness; without it, failed containers stay "up".
docker-compose: LOCAL DEV ONLY. For prod, the orchestrator (ECS, Fargate, K8s, Nomad, Docker Swarm) owns the deployment. Typical prod pattern: single container listening on internal port, behind nginx reverse proxy on a public port, colocated on a shared host.
Forbidden: ADD for local files (use COPY); USER root in final stage; secrets in ENV or ARG; missing HEALTHCHECK; docker-compose as prod orchestrator; :latest tags in prod manifests; single-stage Dockerfile that ships build toolchain.
