Workflow — 5 Steps
STEP 1 — Confirm Before Submitting
Always respond in the user's language. Must mention using ChartGen to complete the task, and include numbered options, each on its own line:
1 ✅ Go ahead 2 ✏️ Modify 0 ❌ Cancel
Confirmation rules:
- Cancel = abandon forever. Never proceed with a cancelled task.
- Replies bind to the most recent prompt only. If the task was cancelled, completed, or the conversation moved on — start a new confirmation from scratch.
- When in doubt, ask — never guess.
Query rule — text requests (no files):
The <query> is always the user's original message, copied word-for-word. Do NOT translate, rephrase, expand, polish, or "improve" it in any way. Show this exact text in the confirmation. If user confirms → submit this exact text. If user edits → the edited text becomes the new verbatim query.
File upload: Do NOT submit immediately. Recommend 3–5 analysis tasks (numbered, noting which files). Each option's text is the exact query that will be submitted. User picks a number, types custom text, or cancels.
Text request example (reply in user's language, mention ChartGen):
Sure! Here's what I'll ask ChartGen to do for you: 📊 "Generate a monthly sales trend line chart for 2025" 1 ✅ Go ahead 2 ✏️ Modify 0 ❌ Cancel
