testear-hasta-rojo

testear-hasta-rojo is a cursor rule for Cursor from LeandroPG19/Memorys. It costs 182 tokens per session, scanned A, original, Apache-2.0.

A testing rule that requires a test to prove the code path works, fail when deliberately broken, and fail clearly when its setup is missing. It forbids silently skipping tests.

In plain words
What is it for?
It helps verify handlers, APIs, database row counts, and ignored tests by running them and checking that they can detect a broken assertion.
Why use it?
It prevents tests from passing only because they checked an empty result or never ran. This makes a passing test more trustworthy.

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

testear-hasta-rojo 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 22d 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

Testear hasta el rojo

  • Primero el ancla de que el handler o la API está (MCP result / HTTP 200 / row count). Afirmar solo ausencia pasa igual sobre un corpus vacío.
  • skip y return silencioso están prohibidos. Si falta el entorno, la corrida falla y lo dice. Sembrar el dato, no saltar.
  • Un test apagado no prueba nada. #[ignore] solo existe porque el SIL los corre (cargo test -- --ignored). Un ignore que el gate no ejecuta es un skip silencioso.
  • Sabotear el assert, ver rojo, luego verde. Un test que nunca se puso rojo no está verificado.

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.
