Dev open-sources TITAN: repo-native Codex methodology with SOL planning, LUNA implementation
sokobih · reddit · 2026-09-14
A developer formalized his Codex workflow into TITAN, an open-source, repo-native methodology. SOL handles discovery, architecture and writes detailed per-module implementation plans after inspecting the actual repo; LUNA implements those plans with a STOP rule—on any mismatch between plan and code it reports back rather than redesigning. Project state, roles and prompts live in the repo (.titan/STATE.md, WORKFLOW.md, docs/PROJECTSPEC.md, DECISIONS.md, etc.) so context survives across sessions. UI tasks are separated from backend logic due to different failure modes; ASTRA serves as an optional critical reviewer. Best suited for long-lived multi-session apps with real business rules; packaged as an open-source starter on npm (npx -y /titan@latest).
