Install cept for Codex and Claude Code

Installs for the current user
claude plugin marketplace add IchenDEV/agent-plugin-mkt
claude plugin marketplace update agent-plugin-marketplace
claude plugin install cept-2@agent-plugin-marketplace

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

Compatibility: the page URL and API slug “cept-2” remain stable.

  • Codex: Legacy selector cept-2@agent-plugin-marketplace remains documented for migration; install from source for this runtime.

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.

Codex has another source with the same manifest name. This directory does not invent numbered install aliases; use the publisher's catalog or inspect the source manually for that runtime.

Get the source manually
git clone https://github.com/eidos-agi/cept

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

Included Skills1

use-ceptskills/use-cept/SKILL.md

Use when the user asks to use Cept or cept, asks for outside-in steering, wants an agent session reviewed, is stuck or looping, needs debugging triage, or wants architecture/research guidance from the recent agent trajectory. This skill tells Codex to call the local Cept CLI or MCP tool first and treat Cept output as evidence to reconcile.
