data-auditor

data-auditor is a skill for Claude Code, Codex from Mazalucas/El-DT-Lightweight-Army. It costs 57 tokens per session (829 once invoked), scanned A, original, MIT.

A data-checking workflow for spreadsheets, CSV files, Excel files, reports, totals, and reconciliations. It verifies numbers with scripts and records where the data came from.

In plain words
What is it for?
Use it to inspect data files, calculate and cross-check totals, find duplicates, reconcile reported figures, and label numbers that could not be verified.
Why use it?
It helps prevent errors from mental arithmetic, misunderstood columns, duplicate rows, wrong units, or totals that do not match their parts.

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

data-auditor 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 11d 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 — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Protocolos DT (heredar)

Subagente del Director Técnico: ordenar, cuestionar, alternativas, Puntos ciegos / Mejoras detectadas, post-delegación. Multi-agente: DEFER: <rol>.

Regla madre (obligatoria)

Regla 16-numeric-grounding: la IA no calcula mentalmente. Todo número entregado sale de un script ejecutado, se deriva con fórmula visible, o se etiqueta [NO VERIFICADO].

Pipeline operativo

  1. Inspeccionar la fuente — formato (CSV/XLSX/TSV/tabla pegada), encoding, separadores, headers, unidades, filas. Nunca asumir estructura: mirar primero.
  2. Detectar runtimepython3 + pandas > python3 stdlib > node. Ver references/verify-recipes.md. Sin runtime → modo degradado (regla 16).
  3. Ejecutar la verificación — primero la tool del repo tools/data/verify-csv.py (stdlib, perfil + sumas Decimal + --assert-total + --duplicates); script ad-hoc solo para lo que la tool no cubra (XLSX, joins, fórmulas de negocio). Cross-checks siempre: total vs partes, conteo filas, tipos/unidades. Si el análisis es recurrente, guardar el script en el repo del usuario.
  4. Reconciliar — comparar output contra totales declarados en la fuente. Discrepancias = hallazgo principal, no se acomodan.
  5. Etiquetar — cada cifra de la entrega lleva [VERIFICADO], [DERIVADO] o [NO VERIFICADO].
  6. Entregar — sección Verificación numérica (fuente, script, checks, conteo de etiquetas).

Trampas frecuentes (checklist)

  • Separador decimal , vs . y miles (1.234,56 vs 1,234.56) — declarar interpretación.
  • Celdas vacías vs cero — no son lo mismo; los vacíos se reportan.
  • Filas de subtotales dentro de los datos — excluirlas antes de sumar.
  • Porcentajes: ¿sobre qué base? Promedio de porcentajes ≠ porcentaje del total.
  • Fechas ambiguas (03/04 — ¿marzo o abril?) — preguntar si cambia el resultado.
  • Monedas mezcladas en una misma columna.
  • Redondeo acumulado: sumar redondeados ≠ redondear la suma.

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.
