Rust Question Router
Version: 2.0.0 | Last Updated: 2025-01-22
v2.0: Context optimized - detailed examples moved to sub-files
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:
## 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 edition rust-version = "1.85" [lints.rust] unsafe_code = "warn" [lints.clippy] all = "warn" pedantic = "warn"
Layer 1 Skills (Language Mechanics)
| Pattern | Route To |
|---|---|
| move, borrow, lifetime, E0382, E0597 | m01-ownership |
| Box, Rc, Arc, RefCell, Cell | m02-resource |

| generic, trait, inline, monomorphization | m04-zero-cost |
| type state, phantom, newtype | m05-type-driven |
| Result, Error, panic, ?, anyhow, thiserror | m06-error-handling |
| Send, Sync, thread, async, channel | m07-concurrency |
| unsafe, FFI, extern, raw pointer, transmute | unsafe-checker |
Layer 2 Skills (Design Choices)
| Pattern | Route To |
|---|---|
| domain model, business logic | m09-domain |
| performance, optimization, benchmark | m10-performance |
| integration, interop, bindings | m11-ecosystem |

Layer 3 Skills (Domain Constraints)
| Domain Keywords | Route To |
|---|---|
| fintech, trading, decimal, currency | domain-fintech |
| ml, tensor, model, inference | domain-ml |
| kubernetes, docker, grpc, microservice | domain-cloud-native |
| embedded, sensor, mqtt, iot | domain-iot |
| web server, HTTP, REST, axum, actix | domain-web |
| CLI, command line, clap, terminal | domain-cli |
| no_std, microcontroller, firmware | domain-embedded |
Error Code Routing
| Error Code | Route To | Common Cause |
|---|---|---|
| E0382 | m01-ownership | Use of moved value |
| 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 |
| E0277 | m04/m07 | Trait bound not satisfied |
| E0308 | m04-zero-cost | Type mismatch |
| 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 |
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-checker (more specific than m11) |
| m06 for general, m13 for domain-specific |
| m12 for design, m01 for implementation |
| rust-learner for version, m11 for integration |
| tokio-* for API, m07 for concepts |
Priority Hierarchy:
1. Error codes (E0xxx) → Direct lookup, highest priority 2. Negotiation triggers (compare, vs, best practice) → Enable negotiation 3. Domain keywords + error → Load BOTH domain + error skills 4. Specific crate keywords → Route to crate-specific skill if exists 5. General concept keywords → Route to meta-question skill
