Meta-Cognition Framework
Core Principle
Don't answer directly. Trace through the cognitive layers first.
Layer 3: Domain Constraints (WHY)
โโโ Business rules, regulatory requirements
โโโ domain-fintech, domain-web, domain-cli, etc.
โโโ "Why is it designed this way?"
Layer 2: Design Choices (WHAT)
โโโ Architecture patterns, DDD concepts
โโโ m09-m15 skills
โโโ "What pattern should I use?"
Layer 1: Language Mechanics (HOW)
โโโ Ownership, borrowing, lifetimes, traits
โโโ m01-m07 skills
โโโ "How do I implement this in Rust?"
Routing by Entry Point
| User Signal |
Entry Layer |
Direction |
First Skill |
| E0xxx error |
Layer 1 |
Trace UP โ |
m01-m07 |
| Compile error |
Layer 1 |
Trace UP โ |
Error table below |
| "How to design..." |
Layer 2 |
Check L3, then DOWN โ |
m09-domain |
| "Building [domain] app" |
Layer 3 |
Trace DOWN โ |
domain-* |
| "Best practice..." |
Layer 2 |
Both directions |
m09-m15 |
| Performance issue |
Layer 1 โ 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 |
| ไบคๆ, ๆฏไป, 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 |
| "ๆฏ่พ", "ๅฏนๆฏ", "compare", "vs", "versus" |
MUST use negotiation |
| "ๆไฝณๅฎ่ทต", "best practice" |
MUST use negotiation |
| Domain + error (e.g., "ไบคๆ็ณป็ป E0382") |
MUST use negotiation |
| Ambiguous scope (e.g., "tokio ๆง่ฝ") |
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"
rust-version = "1.85"
[lints.rust]
unsafe_code = "warn"
[lints.clippy]
all = "warn"
pedantic = "warn"

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) โ Direct lookup, highest priority
2. Negotiation triggers (compare, vs, best practice) โ Enable negotiation
3. Domain keywords + error โ Load BOTH domain + error skills
4. Specific crate keywords โ Route to crate-specific skill if exists
5. General concept keywords โ Route to meta-question skill
