This is a brand new standalone service. It does not replace anything.
It works completely independently — no shared data, no dependencies on other services.
It will be publicly accessible on the internet as a simple health-check endpoint for uptime monitoring.

Everyone. This is a public, unauthenticated health-check endpoint. No login or API key required. It is intentionally open for uptime monitoring tools.

✅ Ready for Implementation

The specification has passed all refinement criteria.

Promptpack (click to expand)

Implementation Prompt Pack

Generated: 2026-02-27T06:37:51Z

Spec

Context

Developers need a minimal health-check microservice template for Node.js projects. This serves as a starting point for any Express-based API.

Goal

This is a brand new standalone service. It does not replace anything.
It works completely independently — no shared data, no dependencies on other services.
It will be publicly accessible on the internet as a simple health-check endpoint for uptime monitoring.

Requirements

GET / returns {"message":"pong"} with status 200
GET /health returns {"status":"ok","uptime":} with status 200
All requests logged to stdout via morgan
Server listens on port 3000
Single server.js file
package.json with express and morgan as dependencies

Scope

In scope

GET / endpoint returning JSON pong response
GET /health endpoint returning JSON status with uptime
Morgan request logging middleware
package.json with start script

Out of scope

Authentication
Database
HTTPS/TLS
Docker
Tests (curl verification only)
Environment variable configuration

Acceptance Criteria (Gherkin)

Feature: PingAPI health-check server

  Scenario: Root endpoint returns pong
    Given the server is running on port 3000
    When I send a GET request to "/"
    Then I receive a 200 response
    And the response body is {"message":"pong"}

  Scenario: Health endpoint returns status
    Given the server is running on port 3000
    When I send a GET request to "/health"
    Then I receive a 200 response
    And the response body contains "status" with value "ok"
    And the response body contains "uptime" as a number

  Scenario: Requests are logged
    Given the server is running on port 3000
    When I send a GET request to "/"
    Then the request is logged to stdout

Architecture alignment

Detected stack: Not detected (repo not accessible)
Relevant modules: None found
Constraints: Follow existing repo patterns and conventions over introducing new ones. Prefer composition over inheritance. Keep modules loosely coupled with clear interface boundaries. No business logic in controllers, routes, or handlers — delegate to services. Side effects (I/O, network, database) belong at the edges, not in core logic. One export per file unless tightly cohesive (e.g., type + factory).
Forbidden paths: .git/, node_modules/, .env, secrets.*, vendor/, pycache/, dist/, build/
Architecture concerns: The specification requires a minimal health-check microservice template for Node.js projects using Express.js. However, the automated scan did not detect any stack or relevant modules in the repository.

Code structure

Module pattern: Monolithic structure with a single entry file for simplicity. This pattern is suitable because the feature is minimal and focused on creating a lightweight health-check server without complex dependencies or shared components.
File conventions: Use descriptive names that clearly indicate the purpose of the file. For example, server.js for the main server file.
Import rules: No specific import rules are necessary for this simple project. Keep imports concise and to the point.
Max file length: 100 lines
Suggested file locations: src/server.js
Notes: Ensure that the single file does not grow too large by keeping it focused on its primary function as a health-check server. If in the future, more features are added, consider refactoring into multiple files.

Security and compliance

Data classification: PUBLIC — The service is a minimal health-check microservice template that only returns basic status information and does not handle any user data.
AuthN/AuthZ: No authentication required (public access) — Since the service is a simple health-check endpoint for uptime monitoring and does not require user interaction, no authentication or authorization mechanisms are necessary.
Logging/Audit: Standard application logging — The service logs all requests to stdout via morgan. There are no sensitive operations that would require additional audit logging.
PII/Secrets: No PII or secrets identified — The service does not store or process any personal or confidential information, passwords, or other sensitive data.
Security constraints: Implement rate limiting; keep dependencies up-to-date and scan for vulnerabilities; ensure the server listens on a secure port (e.g., 443 with TLS); follow existing security patterns and conventions.
OWASP considerations: None identified — The service does not involve any user input, database interactions, or other components that would expose it to common OWASP threats like injection attacks or authentication failures.

Test strategy

Golden build command: docker compose build
Golden test command: docker compose run --rm app pytest

Test layers

Integration tests: httpx/supertest — Test API endpoints with request/response validation

Scenario mapping

Scenario	Layer	Framework	Suggested location
Root endpoint returns pong	integration	httpx/supertest	tests/integration/root_endpoint_returns_pong.test
Health endpoint returns status	integration	httpx/supertest	tests/integration/health_endpoint_returns_status.test
Requests are logged	unit	pytest/jest	tests/requests_are_logged.test

Quality gates

All tests pass (zero failures)
No new lint warnings (eslint/ruff/clippy depending on stack)
Type check passes (tsc --noEmit/mypy/pyright if applicable)
Test coverage does not decrease (report but don't block)
No hardcoded secrets or credentials in test code

Engineering principles and DoD additions

Keep it minimal: one file, two routes, zero config
Use standard Express patterns
Clean JSON responses with proper Content-Type headers

Definition of Done

PR created with changes scoped correctly
All required checks green
Acceptance criteria satisfied

Definition of Ready

Scope in/out defined

⚠️ Contract Validation Failed

The spec passed all Definition of Ready criteria, but farm33 contract validation failed.
The spec is missing parseable fields that farm33 needs to consume it.

Missing:

Golden commands must have Golden build command: and Golden test command: lines
Gherkin must have Feature: and Scenario: blocks
A base ref must be extractable

Next steps:

Fix the missing fields in the spec
Run: vault67 refine 12
