How do I install the Solid Go skill?

Run npx skillmds add majiayu000/solid-go in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Solid Go safe to use?

This skill has not completed SkillMD's automated safety review yet. Capability flags: docs only. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Solid Go?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Solid Go free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

SOLID Go - Modular Architecture

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

fuse-ai-pilot:explore-codebase - Analyze existing architecture
fuse-ai-pilot:research-expert - Verify Go docs via Context7
fuse-ai-pilot:sniper - Post-implementation validation

DRY - Reuse Before Creating (MANDATORY)

Before writing ANY new code:

Grep the codebase for similar interfaces, services, or logic
Check shared locations: internal/core/services/, internal/core/ports/
If similar code exists -> extend/reuse instead of duplicate
If code will be used by 2+ features -> create it in internal/core/

Architecture (Modules MANDATORY)

Layer	Location	Max Lines
Handlers	`internal/modules/[feature]/handlers/`	50
Services	`internal/modules/[feature]/services/`	100
Repositories	`internal/modules/[feature]/repositories/`	100
Ports (interfaces)	`internal/modules/[feature]/ports/`	30
Models	`internal/modules/[feature]/models/`	50
Shared	`internal/core/{services,ports,models}/`	-

NEVER use flat internal/ structure - always internal/modules/[feature]/

Critical Rules (MANDATORY)

Rule	Value
File limit	100 lines (split at 90)
Handlers	< 50 lines, delegate to services
Interfaces	`ports/` directory ONLY
Godoc	Every exported function documented
Accept interfaces	Return structs
Small interfaces	1-3 methods max (Go idiom)

Reference Guide

Concepts

Topic	Reference	When to consult
SOLID Overview	solid-principles.md	Quick reference
SRP	single-responsibility.md	Fat structs
OCP	open-closed.md	Adding providers
LSP	liskov-substitution.md	Contracts
ISP	interface-segregation.md	Fat interfaces
DIP	dependency-inversion.md	Injection
Architecture	architecture-patterns.md	Hex/modular

Templates

Template	When to use
module.md	Feature module structure
service.md	Business logic service
interface.md	Port definition
handler.md	HTTP handler
error.md	Custom errors
test.md	Table-driven tests

Forbidden

Anti-Pattern	Fix
Files > 100 lines	Split at 90
Interfaces in impl files	Move to `ports/` directory
Fat interfaces (4+ methods)	Split into small interfaces
Flat `internal/` structure	Use `internal/modules/[feature]/`
`init()` for dependency wiring	Use constructor injection
