Thicket

A lightweight issue tracker designed for coding agents to track their work in projects.

Overview

Coding agents work well when given tasks that can be accomplished in a single session, but they struggle with more complex work that requires iteration and elaboration over a longer timescale. As agents work, they naturally generate a backlog of bugs, feature requests, and cleanups that often gets lost at the end of each session. If you try to manage this backlog in Markdown, you quickly end up with a mess of half-completed todo lists.

Thicket provides a better way: a lightweight issue tracker designed specifically for managing agentic coding tasks.

How it Works

Instead of prompting agents directly, the agents pull the highest priority ticket from the tracker and work on it.

• Agent-Driven Backlog: As part of their work, agents discover more tasks, which they track by creating tickets.
• Reduced Cognitive Overhead: After resolving a ticket, agents are prompted to create more tickets for follow-on work. This ensures technical discoveries are captured without you needing to generate every prompt yourself.
• Git-Backed Source of Truth: Tickets are stored in a .thicket/tickets.jsonl file tracked by git and shared by everyone working on the project. For efficient queries, data is cached in a local SQLite database that automatically syncs with the JSONL file.

Focus on Strategy

Thicket allows you to focus on strategic decisions and high-level feedback that guides the direction of the project. You set the priorities for where the project should invest, rather than managing individual coding agents.

Installation

The easiest way to install Thicket is via go install:

go install github.com/abarth/thicket/cmd/thicket@latest

This will install the thicket binary to your GOBIN directory (typically ~/go/bin). Ensure this directory is in your PATH.

Alternatively, you can build from source:

git clone https://github.com/abarth/thicket.git
cd thicket
go build -o thicket ./cmd/thicket

Quick Start

1. Initialize your project

thicket init --project TH

2. Launch the TUI

The Terminal UI is the recommended interface for human users. It provides an interactive way to browse, create, and manage tickets.

thicket tui

Key Features:

• Navigation: Use arrow keys or j/k to move through the list.
• Creation: Press n to create a new ticket.
• Management: Press e to edit, c to close, or m to add a comment (in detail view).
• Filtering: Use o, x, i, or a to filter by open, closed, icebox, or all tickets.

CLI Usage

For automation or quick commands, Thicket provides a robust CLI.

# Show the next actionable ticket (most important for agents)
thicket ready

# Add a ticket
thicket add --title "Fix login bug" --type bug --priority 1

# List open tickets
thicket list --status open

All commands support --json for machine-readable output. For the full CLI reference, see docs/CLI.md.

Project Structure

When you run thicket init, it creates the following structure:

your-project/
├── .thicket/
│   ├── config.json      # Project configuration
│   ├── tickets.jsonl    # Ticket data (git-tracked)
│   ├── cache.db         # SQLite cache (git-ignored)
│   └── .gitignore       # Ignores cache.db
├── .agent/
│   └── workflows/
│       └── crank.md     # Workflow for coding agents
└── .claude/
    └── commands/
        └── crank.md     # Symlink to .agent/workflows/crank.md

The .agent/workflows/crank.md file contains the workflow instructions that guide coding agents through the ticket lifecycle. The .claude/commands/crank.md symlink enables the /crank command in Claude Code.

Using the /crank Command

Once initialized, you can use the /crank command in Claude Code or Antigravity to start working on tickets:

/crank

This command instructs the agent to work on the highest priority ticket and to create more tickets for future agents.

For Coding Agents

Thicket is designed to help coding agents track their work. Run thicket quickstart for a workflow guide, or see AGENTS.md for detailed instructions.
