Cogine AI Marketplace

A curated internal marketplace of role-based skills for Codex and Claude Code.

Install the Marketplace

Codex (recommended)

codex plugin marketplace add cogine-ai/marketplace

Then open the Codex App's Plugins page, choose Cogine AI, and install only the role plugins you want. If the Marketplace does not appear immediately, restart Codex once.

Claude Code

claude plugin marketplace add cogine-ai/marketplace

Adding the Marketplace registers its catalog; it does not install every plugin. This is a private repository, so Git must already have access to cogine-ai/marketplace.

Available plugins

Plugin	Skills	Focus
design-engineer-skills	8	UI prototyping, frontend library selection, polish, animation review, and motion design.
coding-engineer-skills	30	Specs, implementation, domain and architecture design, isolated worktrees, frontend and React work, debugging, testing, independent review, security, Git/CI, and multi-repository orchestration.
product-manager-skills	15	Strategy, product judgment, discovery, research, PRDs, prototypes, roadmaps, metrics, design, specs, and tickets.
growth-and-gtm-skills	18	Product marketing, growth models, channels, acquisition, conversion, retention, measurement, PLG sales assist, and recurring execution.
sales-skills	12	Founder-led selling, first customers, prospecting, outreach, calls, enablement, enterprise accounts, pipeline review, and PLG sales integration.
founder-ceo-skills	16	Founder judgment, product-market fit, strategy, decisions, planning, organization, finance, fundraising, and board communication.

Install any plugin from the table with its ID:

# Codex
codex plugin add coding-engineer-skills@cogine-ai

# Claude Code
claude plugin install coding-engineer-skills@cogine-ai

In an existing Claude Code session, run /reload-plugins after installation.

Compatibility

Codex is the primary target. The repository also ships native Claude Code manifests while sharing the same skill folders:

• Codex catalog: .agents/plugins/marketplace.json
• Codex manifests: plugins/*/.codex-plugin/plugin.json
• Claude Code catalog: .claude-plugin/marketplace.json
• Claude Code manifests: plugins/*/.claude-plugin/plugin.json

Update

Codex

codex plugin marketplace upgrade cogine-ai
codex plugin list --json

Confirm that coding-engineer-skills@cogine-ai reports the expected version. Start a new task after upgrading so its skill index is rebuilt.

Claude Code

claude plugin marketplace update cogine-ai
claude plugin update coding-engineer-skills@cogine-ai
claude plugin list --json

Restart Claude Code after the plugin update so the new version is loaded.
