What is docker-deploy?

A deployment guide for packaging Go applications as Docker images and preparing related deployment files.

Dockerizing Go web servers, gRPC services, command-line tools, and background workers, including Docker Compose and CI configuration.

It removes the need to design Docker build stages and supporting configuration from scratch for each Go project.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/daibang123a/golang-agent-skills

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.

Model	Per session	Once invoked
Fable 5.1	$0.00087	$0.01669
Opus 5.5	$0.00035	$0.00668
Sonnet 5.5	$0.00017	$0.00334
Haiku 4.5	$0.00009	$0.00167

Security

Grade A, and why

docker-deploy 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate-dockerfile.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 222 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Docker Deploy for Go

Build and deploy Go applications with production-optimized Docker images. Auto-detects project type and generates appropriate configurations.

How It Works

Agent detects the project type by examining go.mod, main.go, and import paths
Agent generates an optimized multi-stage Dockerfile
Agent creates supporting files (docker-compose, .dockerignore, CI config)
Agent reports image size and build metrics

Project Detection

Signal	Project Type	Base Image
`net/http`, `chi`, `gin`, `echo`	Web server	`distroless/static`
`google.golang.org/grpc`	gRPC service	`distroless/static`
`cobra`, `urfave/cli`	CLI tool	`distroless/static`
No network imports	Worker/batch	`scratch`

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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-deploy is a skill published in the GitHub repository daibang123a/golang-agent-skills (2 stars, last pushed 8mo ago), licensed MIT. It adds 87 tokens to every session and 1,669 once invoked, about $0.0003 per session on Opus 5.5. 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.
