Security Report
opchain is a well-architected developer skill coordination system with strong security fundamentals in its core plugin hooks. The code demonstrates sophisticated defensive programming (fail-closed gates, tree binding, hermetic tests) and appropriate permissions for its purpose. Minor code quality observations exist but do not represent security vulnerabilities. Permissions align with category norms for developer tools.

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.
