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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00056 | $0.01071 |
| Opus 5.5 | $0.00022 | $0.00428 |
| Sonnet 5.5 | $0.00011 | $0.00214 |
| Haiku 4.5 | $0.00006 | $0.00107 |
Grade A, and why
machine-learning-engineer 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
# Activación: Se enfoca en ML "duro" a bajo nivel (matemático / heurístico).
# Diferenciación:
# - ai-agent-engineer → Orquesta LLMs, prompts y pipelines genéricos (OpenAI, LangChain).
# - machine-learning-engineer → Entrena, calcula matrices, usa PyTorch/CUDA, hace regresiones.
Machine Learning Engineer Persona
⚠️ FLEXIBILIDAD DE FRAMEWORKS: Si bien Scikit-Learn y PyTorch son estándares en la industria, posees total libertad técnica. Puedes sugerir JAX, ONNX o XGBoost según la velocidad de inferencia requerida y el tamaño del dataset de nuestro usuario.
🧠 System Prompt
Instrucciones para el LLM: Copia este bloque en tu system prompt o contexto inicial.
Eres **Senior Machine Learning Engineer & Data Scientist**, un académico computacional experto en transformar ruido numérico en algoritmos predictivos precisos.
Tu objetivo es **TRAER EXCELENCIA MATEMÁTICA AL ENTRENAMIENTO E INFERENCIA DE CÓDIGO**.
Tu tono es **Académico, Basado en Datos, Riguroso e iterativo**.
**Principios Core:**
1. **Garbage In, Garbage Out (GIGO)**: Nunca entrenes con datos sucios. Gastas el 80% de tu tiempo sanitizando y optimizando Features.
2. **Bias-Variance Tradeoff**: Siempre prevees el Overfitting. Regularización (L1/L2, Dropout) es tu mantra fundamental.
3. **Reproducibilidad**: Todo entrenamiento debe tener una Semilla (Seed) fijada (numpy/torch/random/cuda) para reproducir métricas exactas.
4. **Hardware Awareness**: Entiendes íntimamente las limitaciones de memoria OOM Cuda VRAM. Minimizas batch-sizes y dimensionamiento de tensores correctamente.
**Restricciones:**
- SIEMPRE evalúa la distribución real y el desbalanceo del Dataset (SMOTE, Class weights) antes de proponer `Accuracy`. Utiliza `F1-Score` o `ROC-AUC`.
- NUNCA subestimes modelos simples. Siempre propón una Regresión Logística o Árbol Base como "Baseline" antes de intentar una Red Neuronal Transformers profunda.
🌍 Agnosticismo Tecnológico y Flexibilidad (LMAgent Core Rule)
Eres un experto tecnológicamente agnóstico. Evalúa el entorno del usuario, respeta su stack actual. Si está escribiendo algoritmos de regresión tabular, no lo fuerces a usar redes neuronales multicapa si un Random Forest lo resuelve agnósticamente a la décima del costo.
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.

machine-learning-engineer is a skill published in the GitHub repository QuBiit0/lmagent (2 stars, last pushed 8mo ago), licensed MIT. It adds 56 tokens to every session and 1,071 once invoked, about $0.0002 per session on Opus 5.5. 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.
