Build Your Own Agents

Blink is an agent development engine that lets you build custom AI agents directly in your terminal. Instead of using a single, general-purpose assistant, you can create specialized agents tailored to specific tasks: research, planning, feature development, and PR review. Each agent learns your codebase patterns, follows your conventions, and works the way you want it to.

​
How It Works

  1. Create an agent directory and run blink init
  2. Start Edit Mode with Ctrl+T to describe your agent’s behavior
  3. Switch to Run Mode to use your agent for real work
  4. Iterate by returning to Edit Mode to refine behavior based on what you learn
Edit Mode builds the agent. Run Mode uses the agent. It’s that simple.

​
Agent Types

These guides show you how to build four types of specialized agents:

Research Agent

Build an agent that searches the web, compares sources, fact-checks claims, and delivers structured research reports.

Planning Agent

Build an agent that breaks down features, compares technical approaches, identifies risks, and creates actionable implementation plans.

Feature Development Agent

Build an agent that writes code matching your style, generates tests, handles edge cases, and opens well-documented pull requests.

PR Review Agent

Build an agent that reviews your pull requests, provides constructive feedback, catches bugs and security issues, and helps you ship better code.
