LangGPT

LangGPT is a structured, reusable prompt design framework. Its official project README provides role, goal, rule and workflow templates, plus variables, commands and example-based learning resources.

Features described on the official site

• The README organizes prompts with Role, Profile, Goal, Skills, Rules, Workflow and Initialization.
• Describes variable references, commands, conditional logic, reminders and alternative JSON/YAML formats.
• Provides quick-start, example and learning resources, with optional GPTs and Claude Code Skill entries.

Suggested starting workflow

• Define the goal, acceptance criteria and constraints before reading the basic structure.
• Choose a relevant example and retain only the modules and variables needed.
• Check costs, licenses and permissions before external model execution or optional Skill installation.

These are editorial starting suggestions based on product purpose, not workflows tested by this site.

Before you use it

• Not tested hands-on here; feature descriptions come from official pages.
• Pricing, regions, languages, commercial use, watermarks and export conditions have not been verified for a single plan.
• Claims that models already know the framework or that it is the most popular were not tested. The README’s MIT badge is not a complete license review; optional tools and ecosystem projects require separate identity and terms checks.

Catalog classification

The official README provides a structured prompt methodology, quick-start and learning resources. Keep prompts and add learning; ecosystem listings do not make it a hosted model or automatically executing agent.
