planning

ark-ai-agent

A modular marketplace of Claude Code plugins for planning, prompting, reflection, and productivity workflows. Install only what you need — each plugin is independent with its own commands, skills, and agents.

Forked from TACHES with added playbook system (ACE pattern) for cross-session knowledge accumulation.

Installation

Selective Install (Recommended)

From within Claude Code:

# Add the marketplace
/plugin marketplace add HelloWorldSungin/ark-ai-agent

# Install only plugins you need
/plugin install consider@ark-ai-agent
/plugin install planning@ark-ai-agent
/plugin install reflection@ark-ai-agent

Or from a local submodule:

/plugin marketplace add ./external/ark-ai-agent
/plugin install consider@ark-ai-agent

Use the interactive /plugin UI to browse all available plugins.

Migration from v2.x

v3.0.0 replaces the monolithic ark-ai-agent plugin with 9 independent plugins. To migrate:

1. Remove the old plugin: /plugin uninstall ark-ai-agent@ark-ai-agent
2. Install the plugins you need (see catalog above)
3. Commands that were ark-ai-agent:consider:first-principles are now consider:first-principles
