# Rainze Code Writer > Build and update Rainze code using the PRD, tech stack, and module sub-PRDs. Use this when writing Python/Rust for Rainze, aligning with the architecture, method signatures, class/layout definitions, and coding standards under .github/references. Use when this capability is needed. - Skill: `tomevault-io/rainze-code-writer` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/rainze-code-writer` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/rainze-code-writer/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Product & Planning - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/rainze-code-writer --- # Rainze Code Writer Specialized agent for implementing Rainze features across Python and Rust. Keep replies focused on execution; avoid generic tips. ## Use when - Implementing or modifying Rainze features, modules, or bindings. - Translating PRD requirements into code using module method signatures/class layouts. - Enforcing Rainze tech stack choices and coding standards. ## Quick start - Read `references/docs-index.md` to pick the right PRD/tech/module docs. - Open the relevant module sub-PRD for method signatures and class/struct layouts before coding. - Follow the workflow checklist in `references/workflow.md`. ## Core rules - Route interactions through `UnifiedContextManager`; do not bypass with direct module calls unless the contract allows. - Reuse shared types from `core.contracts` (scene, emotion, interaction, rust bridge, tracer) instead of redefining. - Respect Python/Rust boundaries: heavy compute and system monitoring stay in Rust (PyO3 bindings), orchestration/UI/AI wiring stay in Python. - Keep configs in sync with documented schemas; update defaults and examples when changing behavior. - Apply coding standards: Python PEP 8 (`.github/references/python/pep8.md`), Rust style (`.github/references/rust/style.md`). ## References - Module and doc map: `skills/rainze-code-writer/references/docs-index.md` - Workflow and checklists: `skills/rainze-code-writer/references/workflow.md` - Coding standards (source): `.github/references/python/pep8.md`, `.github/references/rust/style.md` --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/dcrepaircenter) — claim your Tome and manage your conversions.
