What Workflow Skill Design is

Workflow Skill Design is a plugin published in the trailofbits/skills repository on GitHub, which has about 7.3k stars. The repository describes itself as: “Trail of Bits Claude Code skills for security research, vulnerability detection, and audit workflows”

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 Workflow Skill Design 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 Workflow Skill Design

Claude Code

Add the repository as a plugin marketplace: claude plugin marketplace add trailofbits/skills
Install the plugin: claude plugin install workflow-skill-design@<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 trailofbits/skills (the owner/repo shorthand works for GitHub).
Find Workflow Skill Design in the list, click Install, then connect any connectors it needs from its Connectors tab.

New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.

Installation

Claude Code Marketplace

/plugin marketplace add trailofbits/skills

Browse and Install Plugins

/plugin menu

Codex

Codex supports Claude plugin marketplaces directly, so this repository does not need Codex-specific sidecar metadata.

Install the marketplace with:

codex plugin marketplace add trailofbits/skills
codex plugin list
codex plugin add <plugin-name>@trailofbits

ChatGPT Workspace Marketplace

Use this repository's .claude-plugin/marketplace.json for workspace imports. Skills that include agents/openai.yaml also need interface.display_name and interface.short_description in that YAML file; plugin metadata does not supply them. After a metadata fix is published, sync the repository again in your workspace marketplace to retry failed imports.

Local Development

To add the marketplace locally (e.g., for testing or development), navigate to the parent directory of this repository:

cd /path/to/parent  # e.g., if repo is at ~/projects/skills, be in ~/projects
/plugins marketplace add ./skills

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.
