Setup guide

Transaction Categorization Agent for Gemini

The $19 Transaction Categorization Agent runs on Gemini as three plain-text files: set it up once in a Gemini Gem, approve a sample-data test, then trigger each run with the usage prompt and this run's inputs.

What the Transaction Categorization Agent does

If your team's files live in Google Workspace, Gemini is the shortest path for this agent. It proposes a category for every uncoded transaction with the evidence: date, payee, amount, proposed category, evidence, review status. You approve the batch.

Uncoded transactions pile up all month, and categorizing them means reading payee strings and trying to remember how you coded the same vendor last time.

Where the three files go in Gemini

Create a Gem whose instructions are the skill.md contents plus the setup prompt, then run the setup. Gems keep their instructions between sessions, so the agent's rules persist. For Sheets work, Gemini's Workspace integration makes it the natural home for these agents.

What a run looks like on Gemini

A run looks like this: you open the Gem, give it this run's inputs from the usage prompt, and Gemini works through transaction-categorization. The output - it proposes a category for every uncoded transaction with the evidence: date, payee, amount, proposed category, evidence, review status - can move straight into Sheets and Docs through the Workspace integration. You approve, adjust or discard first.

Setup, step by step

  1. Create a Gem in Gemini and name it after the job (for example: transaction categorization).
  2. Make the Gem's instructions the contents of skill.md plus setup-prompt.txt.
  3. Run the setup conversation; the agent runs transaction-categorization on fictional sample data first - approve that test before real work.
  4. Start each real run with that Gem and paste usage-prompt.txt with this run's inputs. Gems keep instructions between sessions, and Gemini's Workspace integration sits close to your Sheets and Docs.

Honest limits on Gemini

Gems are created and edited on the web, and some Workspace features depend on your plan. As with any assistant, approve the sample-data run before real data.
