## [Introduction] Stellar Frameworks: An Adaptive Complexity Task Workflow Framework for LLM Agents

This article introduces Stellar Frameworks—a universal task workflow framework for LLM agents, using a phase state machine design and supporting four levels of adaptive complexity (Minimal/Simple/Standard/Complex). It aims to solve the fragmentation problem of LLM agent workflows and provide a unified and flexible processing paradigm for various tasks.

## Background: The Fragmentation Dilemma of LLM Agent Workflows

With the evolution of LLM capabilities, agent systems are moving toward practical applications, but developers face the problem of task complexity diversity: the same task has different complexities in different scenarios. Existing frameworks have two extremes: over-simplified (unable to handle complex tasks) or over-complex (code redundancy, difficult maintenance). Stellar Frameworks proposes the concept of "one framework, adaptive complexity" to address this pain point.

## Core Design: Phase State Machine and Four Levels of Adaptive Complexity

### Phase State Machine
Modeling task execution as a state machine, where each state represents a task phase. Advantages include clear phase division, traceable states, flexible transitions, and fault tolerance recovery.

### Four Levels of Adaptive Complexity
| Level | Name | Applicable Scenarios | Resource Consumption |
|------|------|----------------------|----------------------|
|1|Minimal|Simple and direct tasks (clear answers)|Lowest|
|2|Simple|Tasks requiring a small amount of reasoning/search|Low|
|3|Standard|Multi-step reasoning/tool calling tasks|Medium|
|4|Complex|Open-ended problems (in-depth analysis/iterative optimization)|High|

Tasks can be dynamically upgraded/downgraded, not statically assigned.

## Working Principle of the Adaptive Mechanism

### Complexity Evaluator
Evaluate task complexity based on input features, historical patterns, resource constraints, and user preferences.

### Dynamic Path Selection
- Minimal: Direct single LLM call (factual Q&A, simple conversion)
- Simple: Single call + lightweight retrieval/tools (requires a small amount of background knowledge)
- Standard: Multi-phase processing (reasoning chain, tool sequence, verification)
- Complex: Iterative optimization, multi-round dialogue, advanced retrieval (research questions)

### Downgrade and Upgrade Strategies
- Upgrade triggers: Substandard output quality, user requests for details, need for additional steps
- Downgrade triggers: Resource limitations, timeout, user requests for conciseness, simpler task

Bidirectional adaptation ensures optimal resource utilization.

## Practical Application Scenarios

### Customer Service Agent
- Minimal: Business hours inquiry → directly return from knowledge base
- Simple: Password reset → retrieve help document and summarize
- Standard: Order not received → query status + logistics + analyze delay
- Complex: Custom solution → multi-round requirement collection + recommendation + quotation

### Code Assistant
- Minimal: Syntax check, simple refactoring
- Simple: Generate common functions, explain code
- Standard: Debug errors, optimize performance, generate unit tests
- Complex: Architecture design, cross-file refactoring, technology selection

### Research Assistant
- Minimal: Definition explanation, concept clarification
- Simple: Literature search, summary generation
- Standard: Literature review, comparative analysis, hypothesis generation
- Complex: Experiment design, data analysis, paper assistance

## Technical Implementation Considerations

### State Machine Engine
May use existing libraries (Python transitions, TypeScript xstate) or custom implementations. The key points are configurable transitions and observability.

### Prompt Engineering Templates
Each level has supporting prompt templates, which need to be optimized for different LLMs.

### Evaluation and Feedback Mechanism
- Self-evaluation: LLM's confidence in output
- Rule-based evaluation: Heuristic quality checks
- External feedback: User feedback, tool results, downstream success rate

### Tool Integration Layer
Standard/Complex levels need to integrate external tools (search, database, API, etc.), providing unified registration, calling, and error handling.

## Comparison with Existing Solutions

| Feature | Stellar Frameworks | LangChain | AutoGPT | BabyAGI |
|---------|-------------------|-----------|---------|---------|
| Complexity Hierarchy | ✅ Four-level adaptive | ⚠️ Manual configuration required | ❌ Uniformly complex | ❌ Uniformly simple |
| State Machine | ✅ Core design | ⚠️ Partially supported | ❌ None | ⚠️ Simple loop |
| Downgrade Capability | ✅ Supported | ❌ Not supported | ❌ Not supported | ❌ Not supported |
| Versatility | ✅ All tasks | ✅ Wide range | ⚠️ Specific scenarios | ⚠️ Specific scenarios |

Unique value: Combination of adaptability and versatility, providing an automatically adjustable infrastructure.

## Potential Challenges and Improvement Directions

### Potential Challenges
- Accuracy of complexity evaluation: Misjudgment leads to resource waste or quality degradation
- State explosion: Poorly designed phases and transition rules make management difficult
- Trade-off between latency and cost: Complex level has high latency and cost
- Interpretability: Adaptive decisions need to be transparent

### Improvement Directions
- Introduce machine learning to optimize complexity evaluation
- Support user-defined complexity levels
- Add A/B testing framework to compare strategy effects
- Integrate advanced planning algorithms (MCTS, ToT)
