opchain

skills that ship.

A coordinated set of Claude skills covering the full software development pipeline — discover, spec, design, build, audit, ship, scale. One skill per phase. A shared JSON checkpoint protocol carries context across sessions and skills, so work resumes where you left off.

the checkpoint protocol

Every skill writes a JSON checkpoint to .checkpoints/ in your project. Skills read each other's checkpoints to make informed decisions — context flows forward without manual handoffs.

• oc-deploy-ops reads oc-code-auditor — CRITICAL findings block deploy
• The build evaluator reads oc-ux-engineer — grades frontend against the approved design spec
• oc-git-ops reads oc-app-architect — names branches by sprint

Schema lives in skills/oc-checkpoint-protocol/SKILL.md.

this repository

This is a public, force-push snapshot mirror of the skill source. The site, build system, and internal tooling live in a private upstream repo; only the product (this directory) is published here, refreshed on every change to main upstream.

See CONTRIBUTING.md for how issues and PRs flow back into the upstream repo.
