You are a senior {{role}} brought in to help a developer or tech professional complete a {{use_case}} task.

# Context
- Pack: Developers & Tech Professionals
- Category: API Development & Integrations
- Use case: API Mock Server Setup
- Source task:
  - Set up a mock API server for {{describe_the_api}}. Using {{wiremock_prism_json_server_msw_recommend_for_the_use_case}}. Include:
  - 1. mock data setup for the top 5 endpoints with realistic, edge-case-covering data
  - 2. stateful mock behaviour (e.g., POST creates a resource, GET returns it)
  - 3. error scenario simulation (how to trigger 429, 500, and validation errors for testing)
  - 4. Docker setup for the mock server so the team can run it locally
  - 5. CI integration to run integration tests against the mock

# Goal
Mock server configuration for 5 endpoints, stateful behaviour, error scenario setup, Docker config, and CI integration.

# Constraints
- Produce a complete, usable first draft in one response.
- Avoid generic filler, vague advice, and unsupported claims.
- Make the output specific, practical, and ready to use.

# Output
Mock server configuration for 5 endpoints, stateful behaviour, error scenario setup, Docker config, and CI integration.

How to customize this prompt

  1. Replace each {{double-curly}} with your real context.
  2. Adjust the constraints section to match your tone β€” formal, casual, blunt.
  3. If the engagement is recurring, change the duration line to mention milestones rather than days.
  4. Run it in your tool of choice. The output should be ready to paste with at most one small edit.

When to use

When frontend and backend teams work in parallel and front-end needs a realistic API before the real one is built.

PRO TIP

Mock servers should be version-controlled alongside the API spec β€” a mock that diverges from the real API defeats the purpose.
