16-numeric-grounding

16-numeric-grounding is a cursor rule for Cursor from Mazalucas/El-DT-Lightweight-Army. It costs 29 tokens per session (895 once invoked), scanned A, original, MIT.

A method for checking totals, percentages, averages, and other figures with a script instead of mental arithmetic.

In plain words
What is it for?
It helps validate CSV, spreadsheet, report, dashboard, and pasted-table calculations.
Why use it?
It makes calculations reproducible and shows whether each number was verified or derived from source data.

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

16-numeric-grounding 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.

Confianza numérica (numeric grounding)

Fuente humana: docs/03_reference/numeric-verification-default.md (DOC-REF-009). Skill operativa: .cursor/skills/data-auditor/SKILL.md. Subagente: data-auditor. Command: /verificar.

Cuándo aplica

Siempre que la entrega incluya cifras derivadas de datos del usuario o del repo: sumas, promedios, porcentajes, totales, conteos, variaciones, proyecciones, reconciliaciones. Fuentes típicas: planillas (CSV/XLSX/TSV), reportes, tablas pegadas en el chat, exports de sistemas, dashboards.

No aplica a: números literales citados de una fuente sin transformación (citar la fuente), ejemplos ilustrativos marcados como tales, versiones/IDs/números de línea.

Regla de oro

La IA no calcula mentalmente. Todo cálculo sobre datos reales se ejecuta con código (script Python/Node u otra herramienta determinista) y se reporta el output real del script. Prohibido "estimar" un total leyendo una columna, por trivial que parezca.

Etiquetas de procedencia (obligatorias en tareas cuantitativas)

Etiqueta Significado
[VERIFICADO] Salió de un script ejecutado en esta sesión; comando y output reproducibles
[DERIVADO] Calculado a partir de cifras verificadas; la fórmula queda a la vista
[NO VERIFICADO] Citado de una fuente sin recomputar, o sin runtime disponible para verificar

Prohibido entregar cifras sin etiqueta cuando la tarea es cuantitativa.

Cross-checks mínimos

  • Total vs. suma de partes — si hay fila/columna de totales, recomputarla y comparar.
  • Conteo de filas — filas leídas vs. esperadas; detectar headers duplicados, filas vacías, duplicados.
  • Tipos y unidades — moneda, separadores de miles/decimales, porcentajes, fechas; declarar la interpretación asumida.
  • Discrepancias se reportan, nunca se "acomodan" — si los números no cierran, ese es el hallazgo principal de la entrega.

Modo degradado (sin runtime)

No asumir runtime: detectar qué hay disponible (python3 con pandas > python3 stdlib > node). Si no hay ninguno:

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.
