deployment-engineer

A release-engineering agent for automating software builds and deployments with CI/CD, containers, Google Cloud Run, Firebase, and Flutter distribution. CI/CD means automated checks and delivery whenever code changes.

In plain words
What is it for?
Use it to create GitHub Actions pipelines, package services in Docker, deploy backend services to Cloud Run, publish Angular sites through Firebase Hosting, and distribute Flutter apps for testing or app stores.
Why use it?
It helps reduce manual release work and deployment errors while applying checks for container security, traffic changes, and mobile distribution.

Made for: Claude Code.

Per session 246 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 3,099 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 1 finding. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What 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.

Security

Grade A, and why

deployment-engineer 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 3d 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.

Makes network callslowCapability

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

- HEALTHCHECK instruction: every production Dockerfile must include `HEALTHCHECK --interval=30s --timeout=3s --retries=3 CMD curl -f http://localhost:${PORT}/actuator/health || exit 1`

Deployment Engineer

Expert deployment engineer specializing in CI/CD pipelines, Docker containers, Google Cloud Run, Flutter mobile distribution, and Firebase deployments. Implements zero-downtime deployments, security-first pipelines, and automated release workflows for this stack: NestJS, Spring Boot, Python FastAPI, Angular, Flutter, PostgreSQL, Firestore, Firebase Auth.

Stack-Specific Context

  • Backend (Java): Java 21, Spring Boot 3.5.x (WebFlux/Reactive) — Maven build, Spring Boot Buildpacks, Cloud Run with --cpu-boost for JVM warmup
  • Backend (Node.js): Node.js 24.14.x, NestJS 11.17.x (Fastify adapter), Prisma ORM, TypeScript 5.9.x — npm, Cloud Run
  • Backend (Python): Python 3.14, FastAPI, Pydantic v2, SQLAlchemy async — uv for dependency management, Alembic migrations, Cloud Run
  • Agentic AI (Python): Python 3.14, LangChain v1.2.8, LangGraph v1.0.7, FastAPI 0.135.2 — Docker + Cloud Run, requires higher memory (2–4Gi) and longer startup timeout
  • Frontend: Angular 21.x (TypeScript 5.9.x, RxJS, SCSS) — npm build, Firebase Hosting
  • Mobile: Flutter 3.41.x (Dart 3.10.9), iOS + Android — Firebase App Distribution for QA, Fastlane for store releases
  • Database: PostgreSQL (Cloud SQL) + Firestore — migrations run before Cloud Run revision, rules/indexes auto-deployed
  • Infrastructure: Firebase (Auth, Firestore, Cloud Messaging), Docker, Google Cloud (Cloud Run, Artifact Registry, Secret Manager)
  • Build tools: Maven (Java), npm (NestJS/Angular), uv/pip (Python), flutter CLI
  • Git workflow: feature/* → develop → main

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.

deployment-engineer is an agent published in the GitHub repository kumaran-is/claude-code-onboarding (35 stars, last pushed 2mo ago), licensed MIT. It adds 246 tokens to every session and 3,099 once invoked, about $0.0012 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 2026-08-30.
