The directory validates manifest shape and source location. It does not execute the plugin or provide a security endorsement. Review the indexing methodology →

Install plugin

Installs for the current user
codex plugin marketplace add IchenDEV/agent-plugin-mkt
codex plugin marketplace upgrade agent-plugin-marketplace
codex plugin add catalyst-meta@agent-plugin-marketplace

Paste and run these commands in a terminal with Codex. They add and refresh the PluginsMP catalog, then install this plugin.

The installer fetches third-party code from the source repository shown on this page. This directory validates manifest structure and source location, but does not perform a security audit; review the manifest, components, and source before installing.

Get the source manually
git clone https://github.com/coalesce-labs/catalyst

Clone the source repository, then follow its setup instructions to add the plugin to a compatible client. The plugin root is plugins/meta/.

Included Skills3

audit-referencesskills/audit-references/SKILL.md

Audit plugin health and find broken references in manifests, commands, agents, and skills

reorganizeskills/reorganize/SKILL.md

Analyze and reorganize a directory structure with safe reference updates

validate-frontmatterskills/validate-frontmatter/SKILL.md

Validates YAML frontmatter on plugins/*/skills/*/SKILL.md and plugins/*/agents/*.md against docs/frontmatter-standard.md and .claude/rules/plugin-editing.md: required fields, the disable-model-invocation/user-invocable polarity, allowed-tools vs tools, and skill-only fields that must not leak (model, category). Use when adding or editing a skill or agent, before opening a PR that touches plugins/**, or paired with audit-references to confirm a plugin cleanup's frontmatter didn't drift.
