// DATA CONTRACT & DOCUMENTATION
// ============================================================================
//
// This file provides structured provider metadata extracted from TypeScript source.
// It serves as the bridge between the VSCode extension's TypeScript API definitions
// and the CLI's Go-based setup wizard.
//
// CORE STRUCTURES
// ===============
//
// ConfigField: Individual configuration fields with type, category, and validation metadata
//   - Name:        Field name as it appears in ApiHandlerOptions (e.g., "cerebrasApiKey")
//   - Type:        TypeScript type (e.g., "string", "number")
//   - Comment:     Inline comment from TypeScript source
//   - Category:    Provider categorization (e.g., "cerebras", "general")
//   - Required:    Whether this field MUST be collected for any provider
//   - FieldType:   UI field type hint ("password", "url", "string", "select")
//   - Placeholder: Suggested placeholder text for UI input
//
// ModelInfo: Model capabilities, pricing, and limits
//   - MaxTokens:         Maximum output tokens
//   - ContextWindow:     Total context window size
//   - SupportsImages:    Whether model accepts image inputs
//   - SupportsPromptCache: Whether model supports prompt caching
//   - InputPrice:        Cost per 1M input tokens (USD)
//   - OutputPrice:       Cost per 1M output tokens (USD)
//   - CacheWritesPrice:  Cost per 1M cached tokens written (USD)
//   - CacheReadsPrice:   Cost per 1M cached tokens read (USD)
//   - Description:       Human-readable model description
//
// ProviderDefinition: Complete provider metadata including required/optional fields
//   - ID:                Provider identifier (e.g., "cerebras", "anthropic")
//   - Name:              Human-readable display name (e.g., "Cerebras", "Anthropic (Claude)")
//   - RequiredFields:    Fields that MUST be collected (filtered by category + overrides)
//   - OptionalFields:    Fields that MAY be collected (filtered by category + overrides)
//   - Models:            Map of model IDs to ModelInfo
//   - DefaultModelID:    Recommended default model from TypeScript source
//   - HasDynamicModels:  Whether provider supports runtime model discovery
//   - SetupInstructions: User-facing setup guidance
//
// FIELD FILTERING LOGIC
// =====================
//
// Fields are categorized during parsing based on provider-specific prefixes in field names:
//   - "cerebrasApiKey" → category="cerebras"
//   - "awsAccessKey" → category="aws" (used by bedrock)
//   - "requestTimeoutMs" → category="general" (applies to all providers)
//
// The getFieldsByProvider() function filters fields using this priority:
//   1. Check field_overrides.go via GetFieldOverride() for manual corrections
//   2. Match field.Category against provider ID (primary filtering)
//   3. Apply hardcoded switch cases for complex provider relationships
//   4. Include universal fields (requestTimeoutMs, ulid, clineAccountId) for all providers
//
// Required vs Optional:
//   - Fields are marked as required if they appear in the providerRequiredFields map
//     in the generator script (scripts/generate-provider-definitions.mjs)
//   - getFieldsByProvider() respects the required parameter to separate required/optional
//
// MODEL SELECTION
// ===============
//
// DefaultModelID extraction priority:
//   1. Exact match from TypeScript constant (e.g., cerebrasDefaultModelId = "llama-3.3-70b")
//   2. Pattern matching on model IDs ("latest", "default", "sonnet", "gpt-4", etc.)
//   3. First model in the models map
//
// Models map contains full capability and pricing data extracted from TypeScript model
// definitions (e.g., cerebrasModels, anthropicModels).
//
// HasDynamicModels indicates providers that support runtime model discovery via API
// (e.g., OpenRouter, Ollama, LM Studio). For these providers, the models map may be
// incomplete or a representative sample.
//
// USAGE EXAMPLE
// =============
//
//   def, err := GetProviderDefinition("cerebras")
//   if err != nil {
//       return err
//   }
//
//   // Collect required fields from user
//   for _, field := range def.RequiredFields {
//       value := promptUser(field.Name, field.Placeholder, field.FieldType == "password")
//       config[field.Name] = value
//   }
//
//   // Use default model or let user choose
//   if def.DefaultModelID != "" {
//       config["modelId"] = def.DefaultModelID
//   }
//
// EXTENDING & OVERRIDING
// ======================
//
// DO NOT modify this generated file directly. Changes will be lost on regeneration.
//
// To fix incorrect field categorization:
//   - Edit cli/pkg/generated/field_overrides.go
//   - Add entries to GetFieldOverride() function
//   - Example: Force "awsSessionToken" to be relevant for "bedrock"
//
// To change required fields:
//   - Edit providerRequiredFields map in scripts/generate-provider-definitions.mjs
//   - Rerun: npm run generate-provider-definitions
//
// To add new providers:
//   - Add to ApiProvider type in src/shared/api.ts
//   - Add fields to ApiHandlerOptions with provider-specific prefixes
//   - Optionally add model definitions (e.g., export const newProviderModels = {...})
//   - Rerun generator
//
// To fix default model extraction:
//   - Ensure TypeScript source has: export const <provider>DefaultModelId = "model-id"
//   - Or update extractDefaultModelIds() patterns in generator script
//
// For upstream changes:
//   - Submit pull request to src/shared/api.ts in the main repository
//
