go-skills-router — скилл для Claude Code: выбор Go-скиллов

description: >
  Index and routing table for this repository's Go skills: maps a task to
  the skill that owns it, names the secondary skills worth loading
  alongside, and draws the boundary between skills whose triggers overlap.
  Use when it is unclear which Go skill applies, when a task spans several
  concerns at once, when two skills seem to cover the same ground, or when
  the user asks what Go skills are available or wants a project configured
  to load them. Trigger examples: "which skill should I use", "what Go
  skills do you have", "is this concurrency or performance", "set up the
  Go skills for this repo".
  Not for: a task that already maps cleanly to one skill — load that skill
  directly.

# Go Skills Router

This repository publishes 35 Go skills. Their triggers necessarily overlap —
"this is slow" could be performance, concurrency, database, or a leak. Use the
tables below to pick the owner, then load the secondary skills in the same
pass rather than discovering them one at a time.

This is an index. Every skill it names stands alone and can be read without
this one.

## Boundaries Between Overlapping Skills

Load the one that owns the **question being asked**, not the one that matches
a keyword in the code.

**"It is slow."**

- `go-performance-review` — the code allocates or copies too much. Owns
  benchmarks, pprof, and optimisation patterns.
- `go-concurrency-review` — the code contends on a lock or serialises work
  that could run in parallel.
- `go-database` — the query is the problem: missing index, N+1, pool
  exhaustion.
- `go-troubleshooting` — you do not yet know which of the three it is. Start
  here to find out, then hand off.

**"It crashed."**

- `go-troubleshooting` — a panic, deadlock, or leak already happened.
  Diagnosis, profiles, delve.
- `go-defensive-coding` — prevention. Nil traps, aliasing, overflow, the
  constructs that make the next crash impossible.
- `go-concurrency-review` — a data race or a goroutine lifecycle bug.

**"Is this secure?"**

- `go-security-audit` — external threats: injection, auth, secrets, TLS.
- `go-dependency-audit` — known CVEs in modules you import.
- `go-defensive-coding` — internal correctness bugs that are not attacks.

**"How should this be structured?"**

- `go-architecture-review` — the shape of an existing codebase.
- `go-project-layout` — the shape of a new one.
- `go-interface-design` — the shape of one type or contract.
- `go-refactoring` — the *process* of getting from the current shape to the
  target shape. Load it alongside whichever skill above owns that target.

**"How do I expose this?"**

- `go-api-design` — HTTP/REST handlers, routing, middleware, idempotency,
  health checks, shutdown.
- `go-openapi` — the contract is a spec and code is generated from it.
- `go-graphql` — the client picks the shape of the response.
- `go-grpc` — protobuf contract, interceptors, streaming.

**"Tests."**

- `go-test-quality` — what to test, how to isolate it, what to mock,
  synctest, goleak, benchmarks.
- `go-test-table-driven` — the table pattern specifically: when it helps,
  how to shape the case struct, when to stop using it.

**"Style."**

- `go-coding-standards` — the rules the code should follow.
- `go-naming` — what things are called: packages, types, functions,
  receivers, errors.
- `go-code-review` — applying rules to someone else's change, with severity.
- `go-modernize` — rules that changed because the language moved.
- `go-ci` — making a machine enforce them.

**"Ship it."**

- `go-ci` — the pipeline that gates every change: build, lint, test, scan.
- `go-build-release` — turning a tag into signed, reproducible artifacts.
- `go-binary-size` — making those artifacts smaller.

## Which Tool Answers the Question

| Question | Tool | Skill |
|---|---|---|
| Where is this symbol used / implemented, in *this* build? | gopls (MCP server or CLI) | `go-semantic-tools` |
| What is the API of a dependency at the version we use? | `go doc pkg Symbol`, gopls `go_package_api` | `go-semantic-tools` |
| What does another version of a module look like? | `go doc [email protected]` (Go 1.27+), `go list -m -versions` | `go-dependency-audit` |
| Which known vulnerabilities can our code actually reach? | `govulncheck ./...` | `go-dependency-audit` |
| Which packages import which? | `go list -deps`, `go mod graph`, `go mod why` | `go-semantic-tools` |

## Multi-Concern Tasks

A real task usually crosses three skills. Load them together at the start
rather than sequentially.

| Request | Load |
|---|---|
| "Build a gRPC service with tests" | `go-grpc` + `go-test-quality` + `go-error-handling` |
| "This endpoint is slow under load" | `go-troubleshooting` + `go-performance-review` + `go-database` |
| "Harden this service before launch" | `go-security-audit` + `go-dependency-audit` + `go-defensive-coding` + `go-ci` |
| "Split this monolith" | `go-architecture-review` + `go-refactoring` + `go-semantic-tools` |
| "Scaffold a new CLI" | `go-project-layout` + `go-cli` + `go-ci` + `go-binary-size` |
| "Migrate this to the current Go release" | `go-modernize` + `go-test-quality` + `go-ci` |

## Configure a Project to Use These Skills

Asked to make a project load these skills automatically:

1. Find the agent-config files the project already has: `CLAUDE.md`,
   `AGENTS.md`, `GEMINI.md`, `.github/copilot-instructions.md`,
   `.cursor/rules/`.
2. Skip any file that already references `go-skills-router`.
3. Propose this block for each, show the diff, and write only after the
   developer agrees:

   ```markdown
   ## Go skills

   Before any Go coding, review, debugging or setup task, consult the
   `go-skills-router` skill and load the skills it names for the task.
   ```

4. If the team wants some skills on every task regardless of routing
   (for example `go-error-handling` and `go-security-audit`), list them
   under the block as "Always load", with the reason.

## Verification Checklist

1. The primary skill matches the question being asked, not a keyword in the code
2. Secondary skills were loaded in the same pass, not discovered one at a time
3. For a diagnosis task, `go-troubleshooting` ran before an optimisation skill
4. For a restructuring task, `go-refactoring` was paired with the skill owning the target shape
5. If exactly one skill applies, it was loaded directly without routing
6. Project configuration written only after the developer approved the diff
