meta-cognition-parallel runs experimental three-layer parallel Rust meta-cognition analysis.

About

The meta-cognition-parallel skill is an experimental three-layer parallel analysis coordinator for Rust questions triggered by /meta-parallel or parallel analysis keywords. Instead of sequential review, it launches Layer 1 language mechanics, Layer 2 design choices, and Layer 3 domain constraints analyzers then synthesizes cross-layer results into an architectural solution. Agent mode detects layer analyzer files at ../../agents/layer1-analyzer.md through layer3-analyzer.md and launches three general-purpose Tasks in a single message with run_in_background true for true parallelism. Inline mode falls back when agent files are missing, running layers sequentially in the main context. Step one parses user query, code snippets, and domain hints like trading, web, or embedded. Cross-layer synthesis happens in the main context with all layer results before recommending fixes. Example trigger handles E0382 move errors in trading systems. Experimental status version 0.2.0 warns that behavior may change. Contrasts with sequential meta-cognition skills by maximizing throughput on complex Rust debugging questions requiring multiple cognitive perspectives simultaneously.

  • Experimental parallel three-layer Rust analysis via /meta-parallel trigger.
  • Agent mode launches three background Tasks in one message for parallelism.
  • Layers: language mechanics, design choices, domain constraints.
  • Falls back to inline sequential mode when agent files are missing.
  • Cross-layer synthesis produces domain-correct architectural solutions.

Meta-Cognition Parallel Analysis (Experimental)

Status: Experimental | Version: 0.2.0 | Last Updated: 2025-01-27

This skill tests parallel three-layer cognitive analysis.

Concept

Instead of sequential analysis, this skill launches three parallel analyzers - one for each cognitive layer - then synthesizes their results.

Domain-Correct Architectural Solution

Usage

/meta-parallel <your Rust question>

Example:

/meta-parallel 我的交易系统报 E0382 错误,应该用 clone 吗?

Execution Mode Detection

CRITICAL: Check agent file availability first to determine execution mode.

Try to read layer analyzer files:

  • ../../agents/layer1-analyzer.md
  • ../../agents/layer2-analyzer.md
  • ../../agents/layer3-analyzer.md

---

Agent Mode (Plugin Install) - Parallel Execution

When all layer analyzer files exist at `../../agents/`:

Step 1: Parse User Query

Extract from $ARGUMENTS:

  • The original question
  • Any code snippets
  • Domain hints (trading, web, embedded, etc.)

Step 2: Launch Three Parallel Agents

CRITICAL: Launch all three Tasks in a SINGLE message to enable parallel execution.

Read agent files, then launch in parallel:

Task(
  subagent_type: "general-purpose",
  run_in_background: true,
  prompt: <content of ../../agents/layer1-analyzer.md>
          + "\n\n## User Query\n" + $ARGUMENTS
)

Task(
  subagent_type: "general-purpose",
  run_in_background: true,
  prompt: <content of ../../agents/layer2-analyzer.md>
          + "\n\n## User Query\n" + $ARGUMENTS
)

Task(
  subagent_type: "general-purpose",
  run_in_background: true,
  prompt: <content of ../../agents/layer3-analyzer.md>
          + "\n\n## User Query\n" + $ARGUMENTS
)

Step 3: Collect Results

Wait for all three agents to complete. Each returns structured analysis.

Step 4: Cross-Layer Synthesis

With all three results, perform synthesis per template below.

---

Inline Mode (Skills-only Install) - Sequential Execution

When layer analyzer files are NOT available, execute analysis directly:

Step 1: Parse User Query

Same as Agent Mode - extract question, code, and domain hints from $ARGUMENTS.

Step 2: Execute Layer 1 - Language Mechanics

Analyze the Rust language mechanics involved:

## Layer 1: Language Mechanics

**Error/Pattern Identified:**
- Error code: E0XXX (if applicable)
- Pattern: ownership/borrowing/lifetime/etc.

**Root Cause:**
[Explain why this error occurs in terms of Rust's ownership model]

**Language-Level Solutions:**
1. [Solution 1]: description
2. [Solution 2]: description

**Confidence:** HIGH | MEDIUM | LOW
**Reasoning:** [Why this confidence level]

Focus areas:

  • Ownership rules (move, copy, borrow)
  • Lifetime annotations
  • Borrowing rules (shared vs mutable)
  • Error codes and their meanings

Step 3: Execute Layer 2 - Design Choices

Analyze the design patterns and trade-offs:

## Layer 2: Design Choices

**Design Pattern Context:**
- Current approach: [What pattern is being used]
- Problem: [Why it conflicts with Rust's rules]

**Design Alternatives:**
| Pattern | Pros | Cons | When to Use |
|---------|------|------|-------------|
| Pattern A | ... | ... | ... |
| Pattern B | ... | ... | ... |

**Recommended Pattern:**
[Which pattern fits best and why]

**Confidence:** HIGH | MEDIUM | LOW
**Reasoning:** [Why this confidence level]

Focus areas:

  • Smart pointer choices (Box, Rc, Arc)
  • Interior mutability patterns (Cell, RefCell, Mutex)
  • Ownership transfer vs sharing
  • Cloning vs references

Step 4: Execute Layer 3 - Domain Constraints

Analyze domain-specific requirements:

## Layer 3: Domain Constraints

**Domain Identified:** [trading/fintech | web | CLI | embedded | etc.]

**Domain-Specific Requirements:**
- [ ] Performance: [requirements]
- [ ] Safety: [requirements]
- [ ] Concurrency: [requirements]
- [ ] Auditability: [requirements]

**Domain Best Practices:**
1. [Best practice 1]
2. [Best practice 2]

**Constraints on Solution:**
- MUST: [hard requirements]
- SHOULD: [soft requirements]
- AVOID: [anti-patterns for this domain]

**Confidence:** HIGH | MEDIUM | LOW
**Reasoning:** [Why this confidence level]

Focus areas:

  • Industry requirements (FinTech regulations, web scalability, etc.)
  • Performance constraints
  • Safety and correctness requirements
  • Common patterns in the domain

Step 5: Cross-Layer Synthesis

Combine all three layers:

## Cross-Layer Synthesis

### Layer Results Summary

| Layer | Key Finding | Confidence |
|-------|-------------|------------|
| L1 (Mechanics) | [Summary] | [Level] |
| L2 (Design) | [Summary] | [Level] |
| L3 (Domain) | [Summary] | [Level] |

### Cross-Layer Reasoning

1. **L3 → L2:** [How domain constraints affect design choice]
2. **L2 → L1:** [How design choice determines mechanism]
3. **L1 ← L3:** [Direct domain impact on language features]

### Synthesized Recommendation

**Problem:** [Restated with full context]

**Solution:** [Domain-correct architectural solution]

**Rationale:**
- Domain requires: [L3 constraint]
- Design pattern: [L2 pattern]
- Mechanism: [L1 implementation]

### Confidence Assessment

- **Overall:** HIGH | MEDIUM | LOW
- **Limiting Factor:** [Which layer had lowest confidence]

---

Output Template

Both modes produce the same output format:

# Three-Layer Meta-Cognition Analysis

> Query: [User's question]

---

## Layer 1: Language Mechanics
[L1 analysis result]

---

## Layer 2: Design Choices
[L2 analysis result]

---

## Layer 3: Domain Constraints
[L3 analysis result]

---

## Cross-Layer Synthesis

### Reasoning Chain

L3 Domain: [Constraint] ↓ implies L2 Design: [Pattern] ↓ implemented via L1 Mechanism: [Feature]


### Final Recommendation

**Do:** [Recommended approach]

**Don't:** [What to avoid]

**Code Pattern:**

// Recommended implementation

Test Scenarios

Test 1: Trading System E0382

/meta-parallel 交易系统报 E0382,trade record 被 move 了

Expected: L3 identifies FinTech constraints → L2 suggests shared immutable → L1 recommends Arc<T>

Test 2: Web API Concurrency

/meta-parallel Web API 中多个 handler 需要共享数据库连接池

Expected: L3 identifies Web constraints → L2 suggests connection pooling → L1 recommends Arc<Pool>

Test 3: CLI Tool Config

/meta-parallel CLI 工具如何处理配置文件和命令行参数的优先级

Expected: L3 identifies CLI constraints → L2 suggests config precedence pattern → L1 recommends builder pattern

---

Error Handling

ErrorCauseSolution
Agent files not foundSkills-only installUse inline mode (sequential)
Agent timeoutComplex analysisWait longer or use inline mode
Incomplete layer resultAgent issueFill in with inline analysis

Limitations

  • Agent Mode: Parallel execution, faster but requires plugin install
  • Inline Mode: Sequential execution, slower but works everywhere
  • Cross-layer synthesis quality depends on result structure
  • May have higher latency than simple single-layer analysis

Feedback

This is experimental. Please report issues and suggestions to improve the three-layer analysis approach.
