How do I install the Solid Rust skill?

Run npx skillmds@latest add fusengine/solid-rust-3 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 Rust safe to use?

This skill has not completed SkillMD's automated safety review yet. Independent scanners report: SkillSpector: PASS, Skill Scanner: PASS. 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 Rust?

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 Rust free to use?

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

SOLID Rust - 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 Rust 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 traits, services, or logic
Check shared locations: src/core/services/, src/core/traits/
If similar code exists -> extend/reuse instead of duplicate
If code will be used by 2+ features -> create it in src/core/

Architecture (Modules MANDATORY)

Layer	Location	Max Lines
Handlers	`src/modules/[feature]/handlers.rs`	50
Services	`src/modules/[feature]/services.rs`	100
Repositories	`src/modules/[feature]/repository.rs`	100
Traits	`src/modules/[feature]/traits.rs`	30
Models	`src/modules/[feature]/models.rs`	50
Shared	`src/core/{services,traits,models}/`	-

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

Critical Rules (MANDATORY)

Rule	Value
File limit	100 lines (split at 90)
Handlers	< 50 lines, delegate to services
Traits	`traits.rs` or `src/core/traits/` ONLY
Rustdoc	`///` on every public item
Error handling	Use `thiserror` for custom errors
Generics	Use trait bounds, not concrete types

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 impls
LSP	liskov-substitution.md	Trait contracts
ISP	interface-segregation.md	Fat traits
DIP	dependency-inversion.md	Generics/DI
Architecture	architecture-patterns.md	Modular crate

Templates

Template	When to use
module.md	Feature module structure
service.md	Business logic service
trait-def.md	Trait definition
handler.md	HTTP handler (Axum)
error.md	Custom errors (thiserror)
test.md	Unit + integration tests

Forbidden

Anti-Pattern	Fix
Files > 100 lines	Split at 90
Traits in impl files	Move to `traits.rs`
`Box<dyn Any>`	Use proper trait bounds
Flat `src/` structure	Use `src/modules/[feature]/`
Unwrap in library code	Use `Result<T, E>`
