You can build self-contained prompts for work spanning isolated chat sessions. CHAIN mode handles sequential stages where each output generates the next cold-start prompt; FAN-OUT mode creates one prompt per independent task, optionally with a collector prompt.

Practitioners running multi-stage projects across separate chat sessions who cannot rely on shared conversation memory. It suits users requesting 'prompt that generates the next', 'run each stage in a new chat', or 'one prompt per task' handoffs.

Avoid it for a single direct task, open-ended exploration, or same-session parallel subagents. The skill is designed strictly for cross-session handoffs where each stage must emit a self-contained cold-start prompt preserving context and authority.

Prompt-chain is released under the MIT license, making it free to use, modify, and redistribute, including in commercial projects. The current version is 2.3.0, published by Marcel Serrano with no stated fees or usage restrictions.

No external dependencies are declared in the manifest. You only need a chat-based assistant environment where prompts can be copied into new sessions, plus a clearly staged task so each step can emit the next cold-start prompt.
