Version Your Prompts with LangWatch Prompts CLI

Determine Scope

If the user's request is general ("set up prompt versioning", "version my prompts"):

• Read the full codebase to find all hardcoded prompt strings
• Study git history to understand what changed and why — focus on agent behavior changes, prompt tweaks, bug fixes. Read commit messages for context.
• Set up the Prompts CLI and create managed prompts for each hardcoded prompt
• Update all application code to use langwatch.prompts.get()

If the user's request is specific ("version this prompt", "create a new prompt version"):

• Focus on the specific prompt
• Create or update the managed prompt
• Update the relevant code to use langwatch.prompts.get()

Detect Context

This skill is primarily code-path (CLI + SDK). Platform MCP tools exist for prompt management (platform_create_prompt, platform_update_prompt, etc.) but users typically manage prompts directly in the UI. If the user has no codebase and wants to create prompts on the platform, use the platform_create_prompt MCP tool instead.
