System prompt

System prompt is the persistent instruction that sets a model's role and constraints. For system prompt, the useful boundary is the data it uses, the tools it can call, the approvals it needs, the review standard, and the finance decision it may influence before the output is trusted or automated.

Why it matters

Understanding system prompt matters because AI-assisted finance work can sound confident even when data, assumptions, or compute paths are wrong. A useful definition keeps the output grounded, reviewable, and accountable. Pluvo's system instructions enforce that the model asks the engine for numbers rather than estimating them, keeping outputs reproducible and source-traced.

In practice

  • Governance example

    Teams use system prompt when they evaluate whether an AI-assisted analysis can be trusted. The useful test is whether the output is tied to approved data, repeatable logic, human review, and an audit trail.

  • Pluvo example

    Pluvo's system instructions enforce that the model asks the engine for numbers rather than estimating them, keeping outputs reproducible and source-traced.

In practice, teams should define system prompt with a clear source, owner, time period, and decision before they use it in reporting, planning, or operating reviews.

A strong workflow for system prompt separates the definition from the action: first agree what the term means, then decide how it is measured, when it changes, and who is accountable for the next step.

FAQ

What is a system prompt?

System prompt is the persistent instruction that sets a model's role and constraints. For system prompt, the useful boundary is the data it uses, the tools it can call, the approvals it needs, the review standard, and the finance decision it may influence before the output is trusted or automated.

How is a system prompt different from a user prompt?

The boundary for system prompt differs from related terms by scope, source data, time period, and decision use. In this glossary, it covers what a system prompt is — the persistent instruction that sets a model's role and constraints — and how it differs from a user prompt, so teams should compare those boundaries before using it in reporting or planning.
