Pydantic Models
Create Pydantic models following the multi-model pattern for clean API contracts.
Quick Start
Copy the template from assets/template.py and replace placeholders:
{{ResourceName}}→ PascalCase name (e.g.,Project){{resource_name}}→ snake_case name (e.g.,project)
Multi-Model Pattern
| Model | Purpose |
|---|---|
Base |
Common fields shared across models |
Create |
Request body for creation (required fields) |
Update |
Request body for updates (all optional) |
Response |
API response with all fields |
InDB |
Database document with doc_type |
camelCase Aliases
class MyModel(BaseModel):
workspace_id: str = Field(..., alias="workspaceId")
created_at: datetime = Field(..., alias="createdAt")
class Config:
populate_by_name = True # Accept both snake_case and camelCase
Optional Update Fields
class MyUpdate(BaseModel):
"""All fields optional for PATCH requests."""
name: Optional[str] = Field(None, min_length=1)
description: Optional[str] = None
Database Document
class MyInDB(MyResponse):
"""Adds doc_type for Cosmos DB queries."""
doc_type: str = "my_resource"
Integration Steps
- Create models in
src/backend/app/models/ - Export from
src/backend/app/models/__init__.py - Add corresponding TypeScript types
When to Use
This skill is applicable to execute the workflow or actions described in the overview.
AGI Framework Integration

Memory-First Protocol
Retrieve prior API design decisions, database schema choices, and error handling patterns. Cache API response templates for consistent error formatting.
# Check for prior backend/API context before starting
python3 execution/memory_manager.py auto --query "API design patterns and architecture decisions for Pydantic Models Py"
Storing Results
After completing work, store backend/API decisions for future sessions:
python3 execution/memory_manager.py store \
--content "API architecture: REST with HATEOAS, JWT auth, rate limiting at 100 req/min per tenant" \
--type decision --project <project> \
--tags pydantic-models-py backend
Multi-Agent Collaboration
Share API contract changes with frontend agents so they update their client code, and with QA agents for test coverage.
python3 execution/cross_agent_context.py store \
--agent "<your-agent>" \
--action "Implemented API endpoints — 5 new routes with OpenAPI spec and integration tests" \
--project <project>
Agent Team: Code Review
After implementation, dispatch code_review_team for two-stage review (spec compliance + code quality) before merging.
