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.

install
Claude Code — plugin (recommended)
Ships the skills plus the hooks that enforce them: a commit gate bound to the code being committed, pipeline state at session start, and a pointer to the next skill when one finishes.

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-opsreadsoc-code-auditor— CRITICAL findings block deploy- The build evaluator reads
oc-ux-engineer— grades frontend against the approved design spec oc-git-opsreadsoc-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.
