Multi-Model Instruction Execution Architecture#

Provider Abstraction Model:#

Component	Responsibility	Interface
LLM Provider	Model communication	`generate_response(prompt, **kwargs)`
Instruction Executor	Task-specific processing	`execute(instruction, content, context)`
Content Analyzer	Content understanding	`analyze(content, type)`
Security Manager	Validation and safety	`validate_instruction(instruction, domain)`

Content Analysis Execution Framework#

Analysis Workflow Design:#

┌─────────────────────────────────────────────────────────────────┐
│                Content Analysis Pipeline                        │
├─────────────────────────────────────────────────────────────────┤
│  Instruction   →   Prompt     →   LLM        →   Response       │
│  Processing        Building       Execution      Processing      │
│                                                                 │
│  ┌───────────┐   ┌─────────┐   ┌─────────┐   ┌─────────────┐   │

│  └───────────┘   └─────────┘   └─────────┘   └─────────────┘   │
└─────────────────────────────────────────────────────────────────┘

Prompt Construction Strategy:#

Element	Purpose	Template

| **System Role**    | Establish AI capability context         | "You are an advanced content analysis system..." |
| **Analysis Rules** | Define specific extraction requirements | "Extract entities: {entity_types}"               |
| **Output Format**  | Specify response structure              | "Format as: {format_type}"                       |
| **Constraints**    | Apply processing limitations            | "Confidence threshold: {threshold}"              |

Dynamic Instruction Generation#

Content-Adaptive Instruction Architecture:#

┌─────────────────────────────────────────────────────────────────┐
│            Dynamic Instruction Generator                        │

Optimization Goal Mapping:#

Goal	Instruction Template	Priority Scoring
Entity Extraction	Content analysis with domain-specific entities	High for structured data
Content Summarization	Adaptive summarization level based on length	Medium for all content types
Sentiment Analysis	Multi-dimensional sentiment scoring	Low for factual content
Fact Validation	Cross-reference and accuracy checking	Critical for claims
