bicho-testing

bicho-testing is an agent for coding agents from antoniovazquezaraujo/LeTrain. It costs 0 tokens per session (198 once invoked), scanned A, original, Apache-2.0.

A quality-engineering guide for LeTrain that focuses on TDD and BDD, ways of developing and checking software through tests and stated behavior.

In plain words
What is it for?
It helps create unit and integration tests with JUnit 5 and Mockito, check security rules, maintain test documentation, and track coverage.
Why use it?
It helps catch regressions and ensures tests continue to represent the documented business rules.

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

bicho-testing 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 today.

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 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.

bicho-testing is an agent published in the GitHub repository antoniovazquezaraujo/LeTrain (12 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 198 tokens. 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 2026-09-04.
