Terrain v0.9.0
Terrain prepares the ground so AI agents don't have to guess where to stand.
An engineering environment manager for humans and AI coding assistants — knowledge as the map, tools as the roads, conventions as the trail markers. This first stable release ships the full platform built on the Litho (deepwiki-rs) documentation engine.
Highlights
- Knowledge as the map — auto-generated, always-in-sync C4 docs and agent context, produced from your code and consumed by both humans and agents
- Dual-track docs — narrative
human/docs for people, structuredagent/context.md+ grep-friendlyrepomix.mdfor agents, with freshness scoring and incremental updates - AI-native — speaks ACP, so Claude Code, Codex, OpenCode, and Cursor read the same knowledge layers through
terrain tools - Tools as the roads —
terrain env applyinstalls Skills, CodeGraph, RTK, andAGENTS.mdin one command - Conventions as trail markers — four-phase SDD workflow (requirements → design → codegen → review) producing reviewable Markdown artifacts
- Desktop app + CLI — browse, search, and ask questions over your codebase with the integrated Litho Book reader and DeepWiki-style Q&A
