Install Kai agents into OpenCode, Gemini CLI, or Claude Code with one command. No separate CLI needed.

01 — Install

Run the Installer

Downloads the latest Kai release and configures it for your platform of choice.

OpenCode — Kai installed as your default agent:

curl -fsSL https://kai.21no.de/scripts/installer.sh | bash -s -- latest --yes

Gemini CLI — Kai becomes your default persona:

curl -fsSL https://kai.21no.de/scripts/installer-gemini.sh | bash -s -- latest --yes

Claude Code — Kai available as an explicitly-invoked subagent:

curl -fsSL https://kai.21no.de/scripts/installer-claude.sh | bash -s -- latest --yes
02 — Verify

Check Installation

Confirm your platform's CLI is installed and Kai agent definitions are loaded.

opencode --version
03 — Execute

Start Using Kai

Run your platform's CLI with any task. Kai analyzes, routes, and orchestrates automatically. On Claude Code, summon Kai with claude --agent kai or an @agent-kai mention.

Built for Autonomous Execution

Kai operates through OpenCode, Gemini CLI, and Claude Code, orchestrating specialized agents and enforcing quality gates across all workflows.

🧠

Intelligent Routing

Analyzes intent and automatically routes to the right specialist agents — from quick fixes to complex engineering pipelines.

⚡

Parallel Execution

Runs @reviewer, @tester, and @docs simultaneously after implementation. Maximum efficiency, minimal wait time.

🔒

Security First

Enforced deny-lists for dangerous commands. Filesystem boundaries prevent accidental system modifications.

📊

Quality Gates

Strict validation at every phase: code quality, test coverage, security scans, and documentation checks.

💾

Project Memory

Persistent .kai/ directory stores conventions, decisions, and failure patterns. Never rediscover context.

🎯

Deterministic Output

Temperature strategy ensures precision. Specialists locked at 0.1 for consistent, predictable results.

Single Brain, Multiple Specialists

Kai analyzes your request and orchestrates the right specialists. You focus on what to build, Kai handles how.

Fast-Track Team

@explorer, @doc-fixer, @quick-reviewer, @dependency-manager. Target: <10 minutes.

Research Team

@research for deep investigation, @fact-check for verification. Variable duration based on scope.

Engineering Pipeline

@architect → @developer → (@reviewer + @tester + @docs in parallel) → @devops.

Learning Team

@postmortem for failure analysis, @refactor-advisor for tech debt detection and health scoring.

Quality Team

@security-auditor, @performance-optimizer, @integration-specialist, @accessibility-expert. Rigorous quality assurance at every phase.

Utility Team

@executive-summarizer, @jira-writer. Concise briefings for leadership and stakeholders; automated Jira ticket creation and updates.

Leverage the Entire Ecosystem

Kai isn't just another tool. It's a complete orchestration layer that runs on OpenCode, Gemini CLI, and Claude Code — giving you instant access to specialized agents, persistent memory, and extensible workflows.

🔌

Drop-in Integration

🚀

Instant Productivity

21 specialized agents ready to work. From quick fixes to complex engineering pipelines, everything is orchestrated automatically.

🧩

Extensible by Design

Portable across OpenCode, Gemini CLI, and Claude Code. Add your own agents, customize workflows, and extend capabilities without forking.

💡

Smart Context

Persistent .kai/ memory stores conventions, decisions, and patterns. Your projects get smarter with every run.

⚙️

Zero Lock-in

Standard Markdown agent definitions per platform. No proprietary formats, no vendor lock-in. Switch, modify, or remove anytime.
