Basic Code Generation

The KimiCoder / KimiSwarm snippets below illustrate workflow patterns (pseudo-code), while production integration should follow Moonshot's OpenAI-compatible API examples.

# Simple code generation with Kimi K2.5
from kimi import KimiCoder

coder = KimiCoder(
    model="kimi-k2.5",
    enable_swarm=True,
    max_agents=10
)

# Generate a function
result = coder.generate(
    prompt="""
    Create a Python function that:
    - Takes a list of transactions
    - Groups them by category
    - Returns a summary with totals
    - Handles edge cases (empty lists, invalid data)
    - Include type hints and docstrings
    """,
    language="python",
    include_tests=True
)

print(result.code)
print(result.tests)

Kimi K2.5 Coding Plan: Project Workflows

Phase 1: Requirements Analysis with Agent Swarm

# Multi-agent requirements analysis
async def analyze_requirements(spec_document):
    swarm = KimiSwarm(
        agents=[
            {"role": "functional_analyst", "count": 3},
            {"role": "technical_architect", "count": 2},
            {"role": "security_reviewer", "count": 1},
            {"role": "performance_expert", "count": 1}
        ],
        coordination="parallel"
    )
    
    results = await swarm.analyze(
        document=spec_document,
        context_window=256000,
        output_format="structured_requirements"
    )
    
    return {
        "functional_requirements": results.functional,
        "technical_requirements": results.technical,
        "architecture_recommendations": results.architecture,
        "security_considerations": results.security,
        "performance_targets": results.performance
    }

Phase 2: Architecture Design

# AI-assisted architecture design
def design_system_architecture(requirements):
    architect = KimiCoder(
        swarm_agents=20,
        specialization="architecture"
    )
    
    architecture = architect.design(
        requirements=requirements,
        constraints={
            "scalability": "horizontal",
            "budget": "optimize_for_cost",
            "latency": "sub_100ms_p95"
        },
        deliverables=[
            "system_diagram",
            "data_flow",
            "api_specifications",
            "deployment_topology"
        ]
    )
    
    return architecture

Phase 3: Implementation with Visual Coding

Kimi K2.5's visual coding capability transforms UI development:

# Generate React components from Figma screenshots
from kimi.visual import VisualCoder

visual_coder = VisualCoder(model="kimi-k2.5")

# Process design mockup
components = visual_coder.generate_ui(
    image_path="dashboard_mockup.png",
    framework="react",
    styling="tailwind",
    include_responsive=True,
    accessibility_compliant=True
)

# Output includes:
# - React component files
# - CSS/Tailwind styles
# - Props interfaces
# - Storybook stories
# - Unit tests

Phase 4: Code Review and Quality Assurance

# Automated code review with Agent Swarm
def swarm_code_review(pull_request):
    review_swarm = KimiSwarm([
        {"name": "style_checker", "focus": "code_style"},
        {"name": "logic_reviewer", "focus": "algorithm_correctness"},
        {"name": "security_scanner", "focus": "vulnerabilities"},
        {"name": "performance_analyzer", "focus": "optimization"},
        {"name": "test_validator", "focus": "coverage_quality"}
    ])
    
    review = review_swarm.analyze_code(
        files=pull_request.files,
        diff=pull_request.diff,
        context_window=256000  # Full codebase context
    )
    
    return {
        "approvals": review.passed_checks,
        "issues": review.findings,
        "suggestions": review.improvements,
        "security_flags": review.vulnerabilities,
        "approve": review.overall_score > 0.85
    }

Visual Coding: The Game Changer

    # Step 1: Analyze design
    analysis = await kimi.visual.analyze(design_file)
    
    # Step 2: Generate component hierarchy
    components = await kimi.visual.generate_components(
        analysis=analysis,
        tech_stack={
            "frontend": "react",
            "styling": "styled-components",
            "state": "redux"
        }
    )
    
    # Step 3: Create responsive breakpoints
    responsive = await kimi.visual.add_responsive_design(
        components=components,
        breakpoints=["mobile", "tablet", "desktop", "wide"]
    )
    
    # Step 4: Generate assets and exports
    assets = await kimi.visual.extract_assets(design_file)
    
    return {
        "code": responsive.code_files,
        "assets": assets.optimized_images,
        "documentation": responsive.docs
    }

    def __init__(self):
        self.kimi = KimiCoder(enable_swarm=True)
        self.error_history = []
    
    async def execute_with_healing(self, code, test_cases):
        try:
            result = execute(code)
            return result
        except Exception as e:
            # Deploy repair agents
            repair_swarm = self.kimi.swarm(
                agents=[
                    {"role": "error_analyzer"},
                    {"role": "fix_generator"},
                    {"role": "test_validator"}
                ]
            )
            
            fix = await repair_swarm.repair(
                error=e,
                code=code,
                tests=test_cases,
                history=self.error_history
            )
            
            # Validate fix
            if fix.passes_tests:
                self.error_history.append({
                    "error": str(e),
                    "fix": fix.code
                })
                return execute(fix.code)
            else:
                raise RepairFailed(fix.reason)

Pattern 2: Parallel Feature Development

# Develop multiple features simultaneously
async def parallel_feature_development(features, base_codebase):
    swarm = KimiSwarm(
        max_agents=min(len(features) * 5, 100),
        coordination="isolated"  # Prevent conflicts
    )
    
    # Deploy feature teams
    feature_agents = [
        {
            "feature": feature,
            "agents": [
                {"role": "implementer"},
                {"role": "test_writer"},
                {"role": "integrator"}
            ]
        }
        for feature in features
    ]
    
    results = await swarm.develop_parallel(
        features=feature_agents,
        base=base_codebase,
        merge_strategy="feature_flags"
    )
    
    return results.branches  # Separate branches for each feature

Pattern 3: Legacy Code Migration

# Automated legacy migration with full context
async def migrate_legacy_system(old_codebase, target_tech):
    migrator = KimiCoder(context_window=256000)
    
    # Analyze entire legacy system
    analysis = await migrator.analyze(
        codebase=old_codebase,
        include_dependencies=True,
        include_business_logic=True
    )
    
    # Create migration plan with Agent Swarm
    swarm = KimiSwarm(agents=50)
    
    migration_plan = await swarm.create_migration_plan(
        analysis=analysis,
        target=target_tech,
        constraints={
            "zero_downtime": True,
            "data_integrity": "strict",
            "rollback_strategy": "automated"
        }
    )
    
    # Execute migration in phases
    for phase in migration_plan.phases:
        result = await swarm.execute_phase(phase)
        if not result.success:
            await swarm.rollback(phase)
            raise MigrationError(result.errors)
    
    return migration_plan.new_codebase
