What Lucidchart Pack is

Lucidchart 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 Lucidchart 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.

How to install Lucidchart Pack

Claude Code

Add the repository as a plugin marketplace: claude plugin marketplace add jeremylongshore/tons-of-skills-marketplace
Install the plugin: claude plugin install lucidchart-pack@<marketplace-name>, using the marketplace name from the repository's .claude-plugin/marketplace.json.
Restart the session if the new skills or commands don't appear straight away.

Claude Cowork

Open Customize → Plugins and choose Add marketplace.
Enter jeremylongshore/tons-of-skills-marketplace (the owner/repo shorthand works for GitHub).
Find Lucidchart Pack in the list, click Install, then connect any connectors it needs from its Connectors tab.

Inside the source file

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

> Eighteen governed workflows for Lucid REST operations, Standard Import, editor extensions, and data connectors.

This pack is grounded in Lucid's public developer contracts. It distinguishes API keys, OAuth user tokens, and OAuth account tokens; uses Bearer authorization and operation-specific API versions; treats rate limits as endpoint-specific; and uses the official lucid-package and lucid-extension-sdk tooling.

It does not claim universal quotas, document locking, generic document/shape/collaboration webhooks, fabricated signature headers, or per-export/API-call pricing. The webhook workflow is intentionally limited to the documented data-connector model.

Installation

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

Workflows

Each skill carries its own dated official-source map. Re-fetch the exact operation page and inspect installed CLI/SDK types before relying on a scope, header, endpoint, command, limit, event, or compatibility claim.

Validation

python3 scripts/validate-skills-schema.py --marketplace --min-grade A --verbose \
  plugins/saas-packs/lucidchart-pack
python3 -m unittest tests.test_lucidchart_pack_contract

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.
