| Parameter | Type | Required | Description | |-----------|------|----------|-------------| | industry | string | No | Filter to one industry | | search | string | No | Search by keyword |

list_industries

How It Works

1. You ask for a prompt by agent name (or any custom role)
2. The server looks up the agent in the registry for description and industry context
3. It constructs a meta-prompt using Prompt Forge's v2 template (XML-tagged, 8-section structure)
4. It calls the Claude API to generate the system prompt
5. The complete system prompt is returned — ready to paste into any AI tool

Cost

Each generate_prompt call uses approximately $0.02 of Claude API credits (Sonnet model, ~4K output tokens).

list_agents and list_industries are free — no API call needed.
