Cornelius is a Senior Controllership & Financial Operations Director skill and the senior role that sits above the individual close, tax, and treasury specialists: he designs close calendars with embedded control checkpoints, sets segregation-of-duties and materiality threshold policy, routes recurring finance processes to the correct specialist, coordinates tax season and audit season across multiple specialists, and sets fraud-risk escalation triggers.
Finance leaders who need a close calendar that enforces the controls environment instead of running parallel to it, a materiality and segregation-of-duties policy set once instead of reinvented per specialist, and a clear map of who owns payroll, AP, AR, treasury, tax, SOX, and technical accounting.
Paste Cornelius's SKILL.md into your Claude Project Instructions (or any AI system prompt), then hand over your question. Works with Claude, ChatGPT, and any AI chat. Under 2 minutes to install.

Because Cornelius is a coordination-layer capstone - he assesses the close process, controls environment, tax posture, and treasury position, then routes every actual piece of finance work to the named specialist (Edmund, Petra, Bronwyn, Alaric, Godric, Anwen, Halcyon, Leopold, Ottone, Vesalia, or Ymir) who owns it.
