AI-generated overview

Routes Rust questions to the right skill layer, from language mechanics to domain constraints.

What it does: This skill acts as a router for Rust-related questions. It classifies a query by cognitive layer (language mechanics, design choices, or domain constraints), maps error codes and keywords to specific sub-skills, and specifies when a negotiation protocol or dual-skill loading should be used. It produces routing decisions and answer-format guidance rather than Rust code itself.
When to use it: Use it when a Rust question arrives and you need to decide which skill or layer should handle it. It is suited to compile errors, ownership and lifetime issues, async and concurrency questions, design and best-practice questions, and domain-specific Rust work.
Requirements: No scripts; instructions only. It references sub-files (patterns/negotiation.md, examples/workflow.md, integrations/os-checker.md) and named companion skills, but requires no packages, credentials, or network access beyond the agent.

Meta-Cognition Framework

Core Principle

Don't answer directly. Trace through the cognitive layers first.

Layer 3: Domain Constraints (WHY)├── Business rules, regulatory requirements├── domain-fintech, domain-web, domain-cli, etc.└── "Why is it designed this way?"
Layer 2: Design Choices (WHAT)├── Architecture patterns, DDD concepts├── m09-m15 skills└── "What pattern should I use?"
Layer 1: Language Mechanics (HOW)├── Ownership, borrowing, lifetimes, traits├── m01-m07 skills└── "How do I implement this in Rust?"

Routing by Entry Point

User Signal	Entry Layer	Direction	First Skill
E0xxx error	Layer 1	Trace UP ↑	m01-m07
Compile error	Layer 1	Trace UP ↑	Error table below
"How to design..."	Layer 2	Check L3, then DOWN ↓	m09-domain
"Building [domain] app"	Layer 3	Trace DOWN ↓	domain-*
"Best practice..."	Layer 2	Both directions	m09-m15
Performance issue	Layer 1 → 2	UP then DOWN	m10-performance

CRITICAL: Dual-Skill Loading

When domain keywords are present, you MUST load BOTH skills:

Domain Keywords	L1 Skill	L3 Skill
Web API, HTTP, axum, handler	m07-concurrency	domain-web
交易, 支付, trading, payment	m01-ownership	domain-fintech
CLI, terminal, clap	m07-concurrency	domain-cli
kubernetes, grpc, microservice	m07-concurrency	domain-cloud-native
embedded, no_std, MCU	m02-resource	domain-embedded

INSTRUCTIONS FOR CLAUDE

CRITICAL: Negotiation Protocol Trigger

BEFORE answering, check if negotiation is required:

Query Contains	Action
"比较", "对比", "compare", "vs", "versus"	MUST use negotiation
"最佳实践", "best practice"	MUST use negotiation
Domain + error (e.g., "交易系统 E0382")	MUST use negotiation
Ambiguous scope (e.g., "tokio 性能")	SHOULD use negotiation

When negotiation is required, include:

markdown

## Negotiation Analysis
**Query Type:** [Comparative | Cross-domain | Synthesis | Ambiguous]**Negotiation:** Enabled
### Source: [Agent/Skill Name]**Confidence:** HIGH | MEDIUM | LOW | UNCERTAIN**Gaps:** [What's missing]
## Synthesized Answer[Answer]
**Overall Confidence:** [Level]**Disclosed Gaps:** [Gaps user should know]

Default Project Settings

When creating new Rust projects or Cargo.toml files, ALWAYS use:

[package]edition = "2024"  # ALWAYS use latest stable editionrust-version = "1.85"
[lints.rust]unsafe_code = "warn"
[lints.clippy]all = "warn"pedantic = "warn"

Error Code Routing

Error Code	Route To	Common Cause

E0597	m01-ownership	Lifetime too short
E0506	m01-ownership	Cannot assign to borrowed
E0507	m01-ownership	Cannot move out of borrowed
E0515	m01-ownership	Return local reference
E0716	m01-ownership	Temporary value dropped
E0106	m01-ownership	Missing lifetime specifier
E0596	m03-mutability	Cannot borrow as mutable
E0499	m03-mutability	Multiple mutable borrows
E0502	m03-mutability	Borrow conflict

E0599	m04-zero-cost	No method found
E0038	m04-zero-cost	Trait not object-safe
E0433	m11-ecosystem	Cannot find crate/module

Functional Routing Table

Pattern	Route To	Action
latest version, what's new	rust-learner	Use agents
API, docs, documentation	docs-researcher	Use agent
code style, naming, clippy	coding-guidelines	Read skill
unsafe code, FFI	unsafe-checker	Read skill
code review	os-checker	See `integrations/os-checker.md`

Priority Order

Identify cognitive layer (L1/L2/L3)
Load entry skill (m0x/m1x/domain)
Trace through layers (UP or DOWN)
Cross-reference skills as indicated in "Trace" sections
Answer with reasoning chain

Keyword Conflict Resolution

Keyword	Resolution
`unsafe`	unsafe-checker (more specific than m11)
`error`	m06 for general, m13 for domain-specific
`RAII`	m12 for design, m01 for implementation
`crate`	rust-learner for version, m11 for integration
`tokio`	tokio-* for API, m07 for concepts

Priority Hierarchy:

1. Error codes (E0xxx) → Direct lookup, highest priority2. Negotiation triggers (compare, vs, best practice) → Enable negotiation3. Domain keywords + error → Load BOTH domain + error skills4. Specific crate keywords → Route to crate-specific skill if exists5. General concept keywords → Route to meta-question skill
