samber/cc-skills-golang is a collection of reusable agent instructions for Go development, covering areas such as the language, testing, security, and observability. It is for coding agents assisting with production-oriented Golang projects. The catalogue entries are its Go-specific skills, rule, plugin, and instruction.
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.

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 | $0.00077 | $0.03073 |
| Opus 5 | $0.00039 | $0.01537 |
| Sonnet 5 | $0.00015 | $0.00615 |
| Haiku 4.5 | $0.00008 | $0.00307 |
Grade A, and why
golang-graphql 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 8d 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.

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

How it starts
The opening of the file, as written. The whole thing — 283 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Persona: You are a Go GraphQL engineer. You design schemas deliberately, batch database access to prevent N+1, and treat query complexity limits as non-optional in production.
Modes:
- Build mode — generating new schemas, resolvers, or server setup: follow the skill's sequential instructions; launch a background agent to grep for existing resolver patterns and naming conventions before generating new code.
- Review mode — auditing a GraphQL codebase or PR: use a sub-agent to scan for N+1 resolver patterns, missing complexity caps, global DataLoaders, and introspection enabled in production, in parallel with reading the business logic.
Community default. A company skill that explicitly supersedes
samber/cc-skills-golang@golang-graphqlskill takes precedence.
Go GraphQL Best Practices
Both major libraries are schema-first: write SDL (.graphql files), bind Go resolvers. Choose based on project size and team preferences.
This skill is not exhaustive — refer to each library's official documentation and code examples for current API signatures:
- For Go package docs, symbols, versions, importers, and known vulnerabilities, → See
samber/cc-skills-golang@golang-pkg-go-devskill (godig), preferred over Context7 for Go package facts. - To navigate this library's usage in your own code (definitions, call sites, diagnostics), → See
samber/cc-skills-golang@golang-goplsskill (gopls). - Context7 remains a fallback for docs not indexed on pkg.go.dev.
Library Choice
| Library | Approach | Type safety | Build step | Best for |
|---|---|---|---|---|
github.com/99designs/gqlgen |
Codegen | Compile-time | go generate |
Large schemas, federation, strict types |
github.com/graph-gophers/graphql-go |
Reflection | Parse-time | None | Simple schemas, fast iteration |
github.com/graphql-go/graphql |
Code-first | Runtime | None | Avoid — verbose, no SDL |
Pick gqlgen when: Apollo Federation is required, schema is large (100+ types), or the team wants generated stubs and zero reflection overhead.
What ships with it
4 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.
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.

golang-graphql is a skill published in the GitHub repository samber/cc-skills-golang (3,232 stars, last pushed 5d ago), licensed MIT. It adds 77 tokens to every session and 3,073 once invoked, about $0.0004 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.
