What the Budget Variance Agent does

Muse is built to take actions for you - this agent gives it a concrete job to own. It maintains your approved budget sheet and explains budget-to-actual variance with the source row linked: account, budget, actual, variance, source, explanation.

Explaining variances means hunting through the ledger for what moved, then writing the same overspend paragraph for the fifth month running.

Where the three files go in Muse

Give Muse the three files and ask it to keep skill.md as the standing rules for the job, then run the setup prompt and approve the fictional-data test before pointing it at real work. As with any action-taking agent, keep its approvals on.

What a run looks like on Muse

A run looks like this: you ask Muse to run budget-variance with this run's inputs, and it works through the standing rules. The output - it maintains your approved budget sheet and explains budget-to-actual variance with the source row linked: account, budget, actual, variance, source, explanation - is prepared with its approvals on, so you review before anything happens.

Setup, step by step

  1. Give skill.md, setup-prompt.txt and usage-prompt.txt to Muse and ask it to keep the skill as the standing rules for the job (for example: budget variance).
  2. Run the setup prompt; the agent runs budget-variance on fictional sample data first - approve that test before real work.
  3. Muse is built to take actions, not just answer - keep its approvals on, exactly the gates the agent is designed around.
  4. Trigger each real run with one message and this run's inputs.
