A Go development guide for building applications, libraries, command-line tools, terminal interfaces, web apps, and agent backends using a consistent project structure and tool setup.

Use it when starting or maintaining Go projects, including CLIs, TUIs, web applications, libraries, and Go-based agent services.

It removes guesswork about how to organise, format, test, lint, and run Go code across different project types.

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.

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	$0.00039	$0.03128
Opus 5	$0.00019	$0.01564
Sonnet 5	$0.00008	$0.00626
Haiku 4.5	$0.00004	$0.00313

Security

Grade A, and why

go-stack 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 today.

The scan reads SKILL.md. This mod also ships 2 executable files (references/app.js, references/user-card.js), 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 — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Go Stack Standard

Canonical Go development: scaffolding, libraries, CLI/TUI tools, GOTH web apps, and the Go API side of ADK agents. The agent workflow belongs to google-adk; content sites belong to hugo.

1. Core & Quality Stack

Go version: target latest stable; adopt current idioms mechanically with go fix ./... and gofumpt rather than hand-porting.
Tooling split: standalone CLIs (golangci-lint, gotestsum, air, esbuild) come from mise.toml; tool directives in go.mod hold templ, goimports, gofumpt, and govulncheck, run as go tool <name>.
Tasks and hooks: mise.toml (web) or mise-cli.toml (CLI/agent) per mise; lefthook.yml or lefthook-cli.yml per lefthook.
Linting and formatting: goimports + gofumpt format Go; golangci-lint (golangci.yml) enforces zero warnings; dprint keeps config and markup per dprint.
Testing: standard testing (starters stay dependency-free), stretchr/testify when richer assertions pay off, run through gotestsum.
Logging: log/slog — TextHandler locally with a dynamic slog.LevelVar, JSONHandler in production with trace context.
Observability: OpenTelemetry for web and agents only; SetupOTel (telemetry.go) exports OTLP and stamps trace ids on logs when OTEL_EXPORTER_OTLP_ENDPOINT is set — see observability.
Security checks: govulncheck is check:vuln and gitleaks is check:leaks; SAST is opt-in per opengrep.
Runtime defaults: Go is container-aware (no automaxprocs); use json:",omitzero" instead of omitempty.

2. Project Scaffolding Workflow

Information: define Slug, Import Path (e.g. github.com/username/slug), Package (a valid Go identifier, usually Slug without punctuation), and Holder/Year.
Bootstrap: go mod init <import_path> records the active toolchain version in go.mod.
Tasks and hooks by project type, saved as mise.toml and lefthook.yml:
- Web: mise.toml + lefthook.yml (templ, Tailwind, vendor, and watch tasks).
- CLI/agent: mise-cli.toml + lefthook-cli.yml (same vocabulary, no web tasks).
Config files:
- .golangci.yml from golangci.yml — replace <import_path> there and in the format:go task so format and check agree.
- dprint.json per dprint; .air.toml from air.toml (web only).
- .env.example from env.example (uncomment what the project type uses), .gitignore from gitignore.
- AGENTS.md from AGENTS.md (drop the (web) lines for CLI/agent); LICENSE per project-license.
Toolchain: mise trust && mise install, then go get -tool golang.org/x/tools/cmd/goimports mvdan.cc/gofumpt golang.org/x/vuln/cmd/govulncheck (web adds github.com/a-h/templ/cmd/templ).
Sources:
- cmd/<slug>/main.go from main.go (web), cli.go (CLI), or agent.go (agent, plus go get google.golang.org/adk/v2).
- <package>.go from lib.go with lib_test.go; config/config.go from config.go (CLI/agent may drop Port).
- Web: server.go, server_test.go, middleware.go, telemetry.go.
- Web templates and assets: layout.templ, home.templ, styles.css, app.js, user-card.js.
- Web vendoring: scripts/vendor.go from vendor.go, run once by install:vendor.
Validate: git init --initial-branch=main, then mise run install, mise run format, mise run check, mise run test; before the first commit, check:leaks scans the working tree.
Finish: keep this stack's AGENTS.md when running agent-project, write README.md per readme-agents, then git add . && git commit -m "chore: initial commit".

What ships with it

26 files 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.

Changes

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.

go-stack is a skill published in the GitHub repository fmind/dot (4 stars, last pushed today), licensed MIT. It adds 39 tokens to every session and 3,128 once invoked, about $0.0002 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 2026-09-03.
