Railspike
Railspike gives developers using AI coding agents a file-based process for turning a task into a reviewed plan and then implementation. It keeps plans in the project repository so they can be searched and reused across sessions and agents.
One of 148 tools in Developer Tools
Who it's for
- Software developers using coding agents who want to review and revise a plan before implementation begins.
- Teams that switch between coding agents and want a consistent development process with plans retained in the repository.
- Developers working on features, bug fixes, documentation, or multi-cycle tasks who want to record plans and subtasks.
How it fits your workflow
Install Railspike's prompting files in the project repository and follow the installed WELCOME.md. For a task, ask the agent to write Step 1 of docs/railspike/RAILSPIKE.md.
The prompts guide the work through brainstorming, outlining, planning, and development. The developer can inspect and modify the plan-prompt before the agent starts writing code.
The plans remain as plaintext files in the repository and can be used across sessions or when moving work between coding agents.

Key features
- Four-step development process
- A set of instruction prompts guides work through brainstorming, outlining, planning, and development, with the planning stages recording the chosen approach and breaking work into atomic subtasks.
- Repository-based plan-prompts
- The agent's plan is stored as a file in the repository and then used as its prompt, making it possible for developers to inspect and modify the plan before implementation.
- Agent-agnostic workflow
- The page describes using the same prompting process with multiple coding agents, including handing work between Claude Code and Codex.
- Debug mode
- Railspike includes a debug mode, which the page says was added as the prompting process developed.
- Reusable project installation
- The prompting system can be copied into a project repository or used as a Git submodule to keep up with updates.
Works with
- Cursor, Windsurf, Copilot, Claude Code, and Codex
Alternatives to consider
-
Rinkata
Choose it if you want a shared workspace connecting project goals, specifications, decisions, work, and completion evidence rather than Railspike's repository-based prompting process.
Getting started
- Ask an agent to unpack a Railspike source snapshot into a temporary directory and inspect it for malicious content.
- If no malicious content is found, copy the reviewed snapshot into docs/railspike; the provided installation instructions say not to use a submodule unless requested.
- Follow the installed WELCOME.md.
- For a task, append “Write Step 1 of docs/railspike/RAILSPIKE.md.” to the prompt.
Frequently asked questions
How do I start a task with Railspike?
Append “Write Step 1 of docs/railspike/RAILSPIKE.md.” to your prompt. The page says the original prompt will be preserved in the generated Step 1 document.
Can Railspike be kept up to date?
Yes. The page says it can be used as a Git submodule, and that instructions for doing so are included.
