       Human & LLM Readability Guidelines:

     

       5
       5
       +
       - Clear Module Boundaries: Each feature is a self-contained module with explicit interfaces

     

       6
       6
       +
       - Descriptive Naming: Use full words over abbreviations (e.g., CommunityGovernance not CommGov)

     

       7
       7
       +
       - Structured Documentation: Each module includes purpose, dependencies, and example usage

     

       8
       8
       +
       - Consistent Patterns: RESTful APIs, standard error handling, predictable data structures

     

       9
       9
       +
       - Context-Rich Comments: Explain "why" not just "what" at decision points

     

       10
       10
       +
       

     

       11
       11
       +
       Core Principles:

     

       12
       12
       +
       - When in doubt, choose the simpler implementation

     

       13
       13
       +
       - Features are the enemy of shipping

     

       14
       14
       +
       - A working tool today beats a perfect tool tomorrow

     

       15
       15
       +
       

     

       16
       16
       +
       Utilize existing tech stack

     

       17
       17
       +
       - Before attempting to use an external tool, ensure it cannot be done via the current stack:

     

       18
       18
       +
       - Go Chi (Web framework)

     

       19
       19
       +
       - DB: PostgreSQL

     

       20
       20
       +
       - atProto for federation & user identities

     

       21

       +
       ## Required Layered Architecture

     

       25
       25
       +
       Follow this strict separation of concerns:

     

       26
       26
       +
       ```

     

       27
       27
       +
       Handler (HTTP) → Service (Business Logic) → Repository (Data Access) → Database

     

       28
       28
       +
       ```

     

       29
       29
       +
       

     

       30
       30
       +
       ## Directory Structure

     

       31
       31

       +
       ## Strict Prohibitions

     

       47
       47
       +
       - **NEVER** put SQL queries in handlers

     

       48
       48
       +
       - **NEVER** import database packages in handlers

     

       49
       49
       +
       - **NEVER** pass *sql.DB directly to handlers

     

       50
       50
       +
       - **NEVER** mix business logic with HTTP concerns

     

       51
       51
       +
       - **NEVER** bypass the service layer

     

       52
       52
       +
       

     

       53
       53
       +
       ## Required Patterns

     

       54
       54
       +
       

     

       55
       55
       +
       ### Handlers (HTTP Layer)

     

       56
       56
       +
       - Only handle HTTP concerns: parsing requests, formatting responses

     

       57
       57
       +
       - Delegate all business logic to services

     

       58
       58
       +
       - No direct database access

     

       59
       59
       +
       

     

       60
       60
       +
       Example:

     

       61
       61
       +
       ```go

     

       62
       62
       +
       func (h *UserHandler) CreateUser(w http.ResponseWriter, r *http.Request) {

     

       63
       63
       +
           var req CreateUserRequest

     

       64
       64
       +
           json.NewDecoder(r.Body).Decode(&req)

     

       65
       65
       +
           

     

       66
       66
       +
           user, err := h.userService.CreateUser(req)  // Delegate to service

     

       67
       67
       +
           // Handle response formatting only

     

       68
       68
       +
       }

     

       69
       69
       +
       ```

     

       70
       70
       +
       

     

       71
       71
       +
       ### Services (Business Layer)

     

       72
       72
       +
       - Contain all business logic and validation

     

       73
       73
       +
       - Use repository interfaces, never concrete implementations

     

       74
       74
       +
       - Handle transactions and complex operations

     

       75
       75
       +
       

     

       76
       76
       +
       Example:

     

       77
       77
       +
       ```go

     

       78
       78
       +
       type UserService struct {

     

       79
       79
       +
           userRepo UserRepository  // Interface, not concrete type

     

       80
       80
       +
       }

     

       81
       81
       +
       ```

     

       82
       82
       +
       

     

       83
       83
       +
       ### Repositories (Data Layer)

     

       84
       84
       +
       - Define interfaces in core/[domain]/

     

       85
       85
       +
       - Implement in db/postgres/

     

       86
       86
       +
       - Handle all SQL queries and database operations

     

       87
       87
       +
       

     

       88
       88
       +
       Example:

     

       89
       89
       +
       ```go

     

       90
       90
       +
       // Interface in core/users/repository.go

     

       91
       91
       +
       type UserRepository interface {

     

       92
       92
       +
           Create(user User) (*User, error)

     

       93
       93
       +
           GetByID(id int) (*User, error)

     

       94
       94
       +
       }

     

       95
       95
       +
       

     

       96
       96
       +
       // Implementation in db/postgres/user_repo.go

     

       97
       97
       +
       type PostgresUserRepo struct {

     

       98
       98
       +
           db *sql.DB

     

       99
       99
       +
       }

     

       100
       100
       +
       ```

     

       101
       101
       +
       

     

       102
       102
       +
       ## Testing Requirements

     

       103
       103
       +
       - Services must be easily mockable (use interfaces)

     

       104

       ### Code Generation Patterns

     

       114
       114
       +
       When creating new features:

     

       115
       115
       +
       1. Generate interface first in core/[domain]/

     

       116
       116
       +
       2. Generate test file with failing tests

     

       117
       117
       +
       3. Generate implementation to pass tests

     

       118
       118
       +
       4. Generate handler with tests

     

       119
       119
       +
       5. Update routes in api/routes/

     

       120
       120
       +
       

     

       121
       121
       +
       ### Refactoring Checklist

     

       122
       122
       +
       Before considering a feature complete:

     

       123
       123
       +
       - All tests pass

     

       124
       124
       +
       - No SQL in handlers

     

       125
       125
       +
       - Services use interfaces only

     

       126
       126
       +
       - Error handling follows patterns

     

       127
       127
       +
       - API documented with examples

     

       128
       128
       +
       

     

       129
       129
       +
       ## Database Migrations

     

       130
       130
       +
       - Use golang-goose for version control

     

       131
       131
       +
       - Migrations in db/migrations/

     

       132
       132
       +
       - Never modify existing migrations

     

       133
       133
       +
       - Always provide rollback migrations

     

       134
       134
       +
       

     

       135
       135
       +
       

     

       136
       136
       +
       

     

       137
       137
       +
       ## Dependency Injection

     

       138
       138
       +
       - Use constructor functions for all components

     

       139
       139
       +
       - Pass interfaces, not concrete types

     

       140
       140
       +
       - Wire dependencies in main.go or cmd/server/main.go

     

       141
       141
       +
       

     

       142
       142
       +
       Example dependency wiring:

     

       143
       143
       +
       ```go

     

       144
       144
       +
       // main.go

     

       145
       145
       +
       userRepo := postgres.NewUserRepository(db)

     

       146
       146
       +
       userService := users.NewUserService(userRepo)

     

       147
       147
       +
       userHandler := handlers.NewUserHandler(userService)

     

       148
       148
       +
       ```

     

       149
       149
       +
       

     

       150
       150
       +
       ## Error Handling

     

       151
       151
       +
       - Define custom error types in core/errors/

     

       152
       152
       +
       - Use error wrapping with context: fmt.Errorf("service: %w", err)

     

       153
       153
       +
       - Services return domain errors, handlers translate to HTTP status codes

     

       154
       154
       +
       - Never expose internal error details in API responses

     

       155
       155
       +
       

     

       156
       156
       +
       ### Context7 Usage Guidelines:

     

       157
       157
       +
       - Always check Context7 for best practices before implementing external integrations

     

       158
       158
       +
       - Use Context7 to understand proper error handling patterns for specific libraries

     

       159
       159
       +
       - Reference Context7 for testing patterns with external dependencies

     

       160
       160
       +
       - Consult Context7 for proper configuration patterns
