What Sprint (sprint) is

Sprint (sprint) is a plugin published in the jeremylongshore/tons-of-skills-marketplace repository on GitHub, which has about 2.8k stars. The repository describes itself as: “Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com.”

A plugin is a package that bundles skills, slash commands, subagents, hooks, and MCP connectors so they install together. Plugins are plain files with a manifest at .claude-plugin/plugin.json, and they work in both Claude Code and Claude Cowork.

Installing Sprint adds everything it ships in one step. Connectors inside a plugin still need to be connected separately, and hooks and subagents only run in Cowork and Claude Code, not in regular chat.

How to install Sprint (sprint)

Claude Code

  1. Add the repository as a plugin marketplace: claude plugin marketplace add jeremylongshore/tons-of-skills-marketplace
  2. Install the plugin: claude plugin install sprint@<marketplace-name>, using the marketplace name from the repository's .claude-plugin/marketplace.json.
  3. Restart the session if the new skills or commands don't appear straight away.

Claude Cowork

  1. Open Customize → Plugins and choose Add marketplace.
  2. Enter jeremylongshore/tons-of-skills-marketplace (the owner/repo shorthand works for GitHub).
  3. Find Sprint in the list, click Install, then connect any connectors it needs from its Connectors tab.

> Autonomous multi-agent development plugin for Claude Code. Spec-driven, iterative sprints with specialized agents.

Part of Agentic Forge — Claude Code plugins for autonomous AI workflows.

Stop prompting in circles. Sprint replaces ad-hoc AI coding with structured, specification-driven development. Write specs, run /sprint, and let coordinated agents handle the rest.

At its core, the /sprint command is a spec-driven, self-iterative state machine — it reads your specifications, orchestrates specialized agents through defined phases, and loops autonomously until the work is done or validation passes.

What is Sprint?

Sprint is a Claude Code plugin that turns Claude into an autonomous development team:

  • Project Architect analyzes requirements, creates specifications, and coordinates work
  • Implementation Agents (Python, Next.js, CI/CD, or any tech via allpurpose-agent) build features according to specs
  • Testing Agents (QA, UI) validate the implementation
  • Sprint Orchestrator — the self-iterative state machine that manages phases, handoffs, and convergence
You write specs → Agents implement → Tests validate → Iterate until done

The orchestrator drives the loop: specs in, working code out. No manual intervention required between phases.

Why It Works

Unlike single-shot prompting where context bloats and AI mistakes compound, Sprint uses a convergent multi-pass approach:

  • Context preservation — Each agent receives only what it needs (specs, contract, relevant code). No wasted tokens on irrelevant history.
  • Specs shrink, not grow — Completed work is removed from specs. Each iteration focuses only on what remains.
  • Errors get erased — Working code stays untouched while issues get fixed. The signal-to-noise ratio improves with each pass.

Think of it like a diffusion process: the picture starts noisy, but with each iteration, the noise reduces and clarity emerges. By the final pass, only the solution remains.

Most sprints converge well before 5 iterations. If they don't, the system pauses and asks you what to do — adjust specs, continue iterating, or intervene manually. You stay in control.

Multi-Paradigm Design

Sprint is technology-agnostic. While it includes specialized agents for Python/FastAPI and Next.js, the system works with any tech stack:

  • The allpurpose-agent adapts to Go, Rust, Flutter, Ruby, or any technology
  • Create your own specialized agents for your preferred stack
  • The architect automatically selects appropriate agents based on project structure

The Second Brain Effect

Two files give agents persistent memory across sprints — reducing token usage and keeping context focused:

.claude/project-goals.md — The business brain (you maintain this)

  • Product vision and target audience
  • Market analysis and differentiators
  • Success metrics and constraints
  • What you're building and why

The more detail you provide, the sharper and more shrewd the architect becomes.

.claude/project-map.md — The technical brain (architect maintains this)

  • Project structure and architecture
  • API surface and database schema
  • Routes, components, environment variables
  • Where everything lives and how it connects

Agents read this instead of scanning the entire codebase. The architect keeps it lean and current.

Installation

From Agentic Forge (recommended)

# Add the marketplace
/plugin marketplace add damienlaine/agentic-forge

# Install the plugin
/plugin install sprint

# Update to latest version
/plugin marketplace update damienlaine/agentic-forge

Local Development

# Clone this repo
git clone https://github.com/damienlaine/agentic-sprint.git

# Run Claude Code with the plugin
claude --plugin-dir ./agentic-sprint

Quick Start

1. Set Up Your Project

# Interactive project onboarding
/sprint:setup

Before you install

  • Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
  • Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
  • Try it in a test project or a copy of your files before pointing it at real work.
  • Pin the version you tested, and review changes before updating.
  • Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
