Modules

error

Structured error taxonomy for Roma Agent.

history

History compression strategies.

home

Canonical path resolution for ~/.roma/ runtime state.

memory

Memory store trait and types.

os

OS abstraction layer: the Os trait, LocalOs passthrough, MockOs test double (spec: docs/superpowers/specs/2026-08-13-os-abstraction-design.md).

path

Safe path resolution helpers.

rules

Stream rules: user-declared regex guardrails matched against streamed LLM output. See docs/superpowers/specs/2026-08-12-stream-rules-design.md.

session

Chat session: message history and persistence.

session_manager

Session persistence manager.

str_utils

Small string utilities. UTF-8-safe slicing primitives that are stable polyfills for the unstable str::floor_char_boundary / str::ceil_char_boundary APIs.

tokenizer

Token counting.

types

Core data types for Roma Agent.
