Install Guidance

Install in Claude Code

Install through the Claude Code plugin marketplace.

Claude Code plugin docs

Optional: install HOL Guard for Claude Code first, so it can check this plugin's tools on your machine before Claude Code uses them.

1
Add the marketplace
Run this inside a Claude Code session. It registers the marketplace manifest shipped at the repository root. If the repository ships none, add the generated entry from the Advanced section below first.
claude code
2
Find the marketplace and plugin names
The install id is <plugin-entry>@<marketplace-name>, and the marketplace name is declared inside the manifest — it can differ from the repository name. List registered marketplaces to read both names.
shell
3
Install the plugin
Substitute the plugin entry name and the marketplace name shown by the previous step.
claude code

/plugin-directory-preflight:check — Run before uploading a Claude Code plugin to the plugin directory, and again when the upload scan reports a hold. Runs the local gate and validator, reads a scan report compactly, and pins a stubborn hold with a throwaway probe repository instead of guessing. Trigger when the user mentions uploading or submitting a plugin, the directory scan, a hold, a scan report, a policy review, or the MCP_FORWARDS_CREDENTIAL_ENV finding.
