test

A test-writing prompt that creates unit tests for individual functions and integration tests for components working together. It asks for edge cases, error handling, mocked dependencies, and explanations using a common Arrange–Act–Assert structure.

In plain words
What is it for?
Use it to generate test code for functions, modules, and API endpoints, check critical paths, and improve test coverage.
Why use it?
It reduces the work of planning and writing tests, while helping uncover failures on unusual inputs and between connected parts of an application.

Made for: Claude Code.

Per session 6 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 155 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

test 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 3d 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.

What it actually says

Test Generation Task

Please generate comprehensive tests for the provided code including:

1. Unit Tests

  • Test individual functions/methods
  • Cover edge cases and boundary conditions
  • Test error handling
  • Mock external dependencies

2. Integration Tests

  • Test component interactions
  • Verify data flow between modules
  • Test API endpoints (if applicable)

3. Test Coverage

  • Aim for high code coverage
  • Focus on critical paths
  • Include negative test cases

4. Test Structure

  • Use appropriate testing framework
  • Follow AAA pattern (Arrange, Act, Assert)
  • Clear test descriptions
  • Proper setup and teardown

Please include both test code and explanations.

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.

test is a command published in the GitHub repository LEEI1337/phantom-neural-cortex (5 stars, last pushed 6mo ago), licensed MIT. It adds 6 tokens to every session and 155 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
