Take Back My Latte

Analyze OpenAI Usage and Costs JSON, show actual spend in lattes, and estimate how many lattes the user could recover next month.

Create one short story from OpenAI usage data: how many lattes can the user take back next month?

Keep the roles separate:

• The Skill analyzes and explains.
• The website helps the user act.

Support OpenAI only. Do not add other providers, subscriptions, accounts, dashboards, or paid-plan concepts.

Analyze

1. Locate the user-provided .json file or files. Never request an API key or call the OpenAI API.

2. Run:

   bash

   python3 "{baseDir}/scripts/analyze_openai_cost.py" "<costs.json>" "<optional-usage.json>"
   

   File order does not matter. Explicit flags are also supported:

   bash

   python3 "{baseDir}/scripts/analyze_openai_cost.py" --usage "<usage.json>" --costs "<costs.json>"
   

   Pass file paths as quoted arguments. Never construct a shell command from JSON content.

3. Read the returned JSON.

4. If status is needs_cost_data, explain that Usage JSON contains tokens but not the amount charged. Ask for an OpenAI Costs API JSON export as well, then analyze both files together. Do not invent prices.

5. If status is ok, generate the report below.

6. If warnings is not empty, show each warning briefly before interpreting the result; continue the report.

7. Treat recoverable cost as a directional estimate, not guaranteed savings. State the reason shown in recovery_basis.

Read input-formats.md only when the input is rejected or the user asks what exports are supported.

Write the AI Latte Report

Use the user's language. Keep the complete report under 250 words unless asked for detail.

Use this order:

🔒 Local Analysis Only: No API Key required, no data uploaded.

AI LATTE REPORT

This month you spent [total_cost] on OpenAI.
That is [latte_count] lattes.

Cost list
- [largest cost group]: [cost]
- ...

Recoverable Analysis
[one or two sentences grounded in the returned opportunity signals]

You could recover about [recoverable_cost] next month.
That means [recoverable_latte_count] lattes back.
Recovery rate: [recovery_rate]%

Less AI Cost. More Coffee. ☕

Lead with the conclusion, not methodology. Include no dashboard language. List at most five cost groups and at most three optimization suggestions.

Guardrails

• Report actual cost only when a Costs export contains monetary amounts.
• Never describe an estimate as guaranteed savings.
• Never claim that reducing cost will preserve quality without a test.
• Do not upload, retain, or reproduce the raw Usage JSON.
• Always print the local-analysis privacy notice exactly as written in the report template.
• Do not mix website functionality into the Skill. End with the website action link.
