generate-microcks-openapi-samples

generate-microcks-openapi-samples is a skill for Claude Code, Codex from SebastienDegodez/copilot-instructions. It costs 37 tokens per session (2,454 once invoked), scanned A, original, Apache-2.0.

A guide for creating realistic request and response examples for Microcks, a tool that simulates APIs for testing, from an OpenAPI description.

In plain words
What is it for?
Use it to build happy-path, error, and edge-case examples, route requests to different mock responses, and create repeatable API test fixtures.
Why use it?
It avoids placeholder test data and keeps mock examples consistent with the API's defined format and behavior.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

generate-microcks-openapi-samples scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Generate Microcks OpenAPI Examples

Generate realistic, schema-compliant OpenAPI examples (request/response pairs) for Microcks mocks. All examples must be concrete and directly usable—no placeholders or generic values.

When to Use

Use when:

  • Building mock APIs with Microcks using realistic request/response examples
  • Creating test data that matches real-world API behavior (not generic placeholders)
  • Setting up multiple response scenarios for API testing (happy path, errors, edge cases)
  • Configuring smart request routing (dispatching) based on request content
  • Migrating from live APIs to mock endpoints while maintaining realistic behavior
  • Creating reproducible test fixtures with concrete data

Don't use when:

  • Modifying the OpenAPI contract file itself (examples go in separate metadata files)
  • Creating mock data without an OpenAPI schema as source of truth
  • Using generic/placeholder values (defeats purpose of realistic mocking)
  • Static mock responses without routing logic

Core Pattern

1. Start with OpenAPI contract (what API operations exist?)
2. Design realistic scenarios (happy path, errors, edge cases)
3. Create request/response example pairs (concrete data, no placeholders)
4. Define smart routing rules (which scenario matches which request?)
5. Deploy both example data + routing rules to Microcks

Quick Reference

Decision Option
Few scenarios? Use JSON_BODY dispatcher (fast, simple field matching)
Complex routing logic? Use JS dispatcher (modern, recommended for Microcks 1.13+)
Existing Groovy code? Use GROOVY dispatcher (only if explicitly needed or migrating legacy)
Starting fresh? See examples/README.md for complete copy-paste workflows
All dispatcher details? See references/dispatchers-reference.md for syntax & operators

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
