What the publisher says

From the opchain repository's README, as published. We do not edit it. Read it on GitHub

opchain

Opchain 2.0.4 · 36 skills · released September 14–21, 2026.

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 complete skills and plugin hooks for session context and suggestions. Run /oc-enroll in each repository to enable the Git commit gate. Installing the plugin alone does not enroll repositories or enable learning.

/plugin marketplace add asfbay-bit/opchain-skills
/plugin install opchain

Claude Code — zip (skills only, no hooks)

curl -L https://opchain.dev/opchain-skills.zip -o opchain-skills.zip
unzip opchain-skills.zip -d .claude/skills/
claude
> /oc-discover

Claude.ai / Claude Desktop

Download complete skill ZIPs from Install, then use your host's supported skill upload flow. Keep references and runtime files with each skill. Local runtime commands require Node.js 22.13 or newer and a host that can execute them; a hosted chat without local tools cannot run those commands.

Team (check into git)

git add .claude/skills/
git commit -m "chore: add opchain skills"
git push

Upgrade

For an existing repo installation, ask your coding agent to run:

/oc-update check
/oc-update

If you use 1.9 or earlier and the updater is missing, copy the upgrade prompt at the top of Install. It checks the host and published release, then installs the complete package. The updater preserves checkpoints, local tracking consent, usage history and unrelated skills, and backs up replaced Opchain files. Global plugin installations use the host's supported plugin update.

Open a new agent session afterward and run /oc-update check to verify the installed package. Learning remains off until explicitly enabled; provider access and an external reviewer must be configured separately.
