Show HN: Unpack – a lightweight way to steer Codex/Claude with phased docs

apresmoi Wednesday, February 11, 2026

I've been using LLMs for long discovery and research chats (papers, repos, best practices), then distilling that into phased markdown (build plan + tests), then handing those phases to Codex/Claude to implement and test phase by phase.

The annoying part was always the distillation and keeping docs and architecture current, so I built Unpack: a lightweight GitHub template plus docs structure and a few commands that turns conversations into phases/specs and keeps project docs up to date as the agent builds. It can also generate Mintlify-friendly end-user docs.

There are other spec-driven workflows and tools out there. I wanted something conversation-first and repo-native: plain markdown phases, minimal ceremony, easy to adapt per stack.

Example generated with Unpack (tiny pokedex plus random monsters):

Demo: https://apresmoi.github.io/pokesvg-codex/

Phases index: https://github.com/apresmoi/pokesvg-codex/blob/main/.unpack/...

I’d love feedback on what the “minimum good” phase/spec format should be, and what would make this actually usable in your workflow.
