Snippets

If you're managing AI configs in LaunchDarkly and find yourself copying the same persona instructions or safety guardrails across multiple prompts, this handles the dedupe work. It walks you through creating reusable text blocks (snippets) for things like output formats, compliance disclaimers, or domain knowledge, then wiring them into your config variations. The workflow is straightforward: identify repeated text, create snippets with descriptive keys, verify they're saved, and update them when requirements change. One thing to note is that snippet updates create new versions that propagate to all referencing configs, so you need to think through the blast radius before changing widely used guardrails.

Config Prompt Snippets

You're using a skill that will guide you through creating and managing prompt snippets in LaunchDarkly. Your job is to identify reusable text, create snippets, reference them in config variations, and verify everything is wired correctly.

Prerequisites

This skill requires the remotely hosted LaunchDarkly MCP server to be configured in your environment.

Required MCP tools:

create-prompt-snippet -- create a new reusable text block
get-prompt-snippets -- browse existing snippets in the project; with snippetKey, inspect one snippet's content

Optional MCP tools:

update-prompt-snippet -- edit a snippet's text, name, or tags
delete-prompt-snippet -- permanently remove a snippet
update-agent-config with resource: "variation" -- update variation prompts to reference snippets

Core Concepts

What Are Prompt Snippets?

Prompt snippets are named, versioned text blocks stored at the project level. They contain reusable pieces of prompt text — personas, guardrails, output format instructions, domain knowledge — that can be shared across multiple config variations.
