Internal Component Overview

Purpose

This is the inventory of Scriptorium's implemented components for contributors. The architecture policy owns normative boundaries and invariants; public behavior belongs in the linked contracts.

Public And Command Entrypoints

Component	Implemented responsibility	References
Root package scriptorium	Public Go facade that constructs the engine, exposes request/result types and options, and maps internal errors.	Go package contract, adapter internals
cmd/scriptorium	Process entrypoint that delegates command execution to the CLI adapter.	CLI contract, adapter internals

Adapters, Domain, And Use Case

Component	Implemented responsibility	References
internal/adapter/cli	Parses CLI commands, applies application wiring, and handles process input and output.	CLI contract, adapter internals
internal/adapter/http	Maps HTTP requests and responses to domain operations and maps public errors.	HTTP API contract, adapter internals
internal/domain	Defines core request, result, output-contract, and LLM-boundary types.	runner internals
internal/usecase	Implements Runner preparation, execution, validation coordination, and the repairer boundary.	runner internals

Configuration And Sources

Component	Implemented responsibility	References
internal/config	Loads application settings, applies defaults, and applies CLI overrides.	configuration contract, adapter internals
internal/defaults	Holds compile-time default values used when application settings are resolved.	configuration contract
internal/promptdef	Loads prompt definitions from filesystem and fs.FS sources.	configuration contract, source internals
internal/profile	Loads filesystem and fs.FS execution profiles and combines profile repositories.	configuration contract, source internals
internal/profile/builtin	Provides embedded built-in execution profiles as a repository.	configuration contract, source internals
internal/filecatalog	Provides shared YAML discovery and source-root helpers.	source internals
internal/artifact	Reads inline and file-backed input artifacts.	configuration contract, HTTP API contract, source internals
internal/prompt	Renders prompt templates into messages.	runner internals

Formatting, Validation, And Model Access

Component	Implemented responsibility	References
internal/format	Formats prepared-run information for CLI output.	CLI contract, adapter internals
internal/validate	Defines validation interfaces and provides standard filesystem and fs.FS schema validation.	configuration contract, source internals, runner internals
internal/llm	Defines the provider-neutral LLM client boundary and its OpenAI-compatible implementation.	OpenAI-compatible integration, LLM internals, runner internals

Focused internal documents describe the components that have detailed orchestration, adapter, or source behavior. Package tests live alongside the implementation and are identified in those focused documents where relevant.
