What Openevidence Pack is

Openevidence Pack is a plugin published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”

A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.

Installing Openevidence Pack adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.

Inside the source file

An excerpt from plugins/saas-packs/openevidence-pack/.claude-plugin/plugin.json, shared under the repository's MIT license. Read the full file on GitHub.

> Twenty-four source-grounded skills for safe, reviewable use of the documented OpenEvidence product.

This pack covers clinical evidence review, prompting, onboarding, rollout, privacy, security, incident response, and institutional governance. It does not claim that OpenEvidence publishes an API, SDK, webhook contract, developer environment, or numeric rate-limit policy. Compatibility slugs are retained so existing installations and skills.sh links continue to resolve.

Installation

/plugin install openevidence-pack@claude-code-plugins-plus

Safety boundary

OpenEvidence describes its services as informational and educational, not a diagnostic substitute. These skills keep clinical decisions with qualified professionals. Patient data, recordings, access changes, contracts, and production rollout require the accountable organization's approval and applicable law, policy, consent, BAA, MSA, or SLA.

Skills

Evidence

Each skill includes a dated first-party evidence register linking to the OpenEvidence user guide, Terms, Privacy Policy, Security page, and Trust Center. Re-check those sources and institution-specific agreements before production use.

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
