apply-discount

name: apply-discount description: Use this skill to apply a tier-based customer discount. The discount percentages are proprietary and live in the bundled helper script — never guess them. Always invoke the script via Bash.

apply-discount — proprietary discount table

This skill ships its own helper at scripts/discount.py. The discount percentage for each customer tier is defined inside that script and is not visible to you. You must run the helper to get the correct final amount — any "estimate" you produce on your own will be wrong.

Workflow

1. Read the tier and amount from the user's request.

2. Invoke the helper through the Bash tool. The skill folder is exposed via the CLAUDE_CONFIG_DIR environment variable, so the absolute command is:

   python "$CLAUDE_CONFIG_DIR/skills/apply-discount/scripts/discount.py" <TIER> <AMOUNT>
   

3. The script prints a JSON object on stdout with tier, original_amount, discount_pct, discount_amount, and final_amount.

4. Reply with a one-line summary first ("<tier> tier · −X% · final $Y.YY"), then the raw JSON for programmatic consumers.

Example

User: "Apply the tier discount for a SILVER customer with a $480 cart."

You run:

python "$CLAUDE_CONFIG_DIR/skills/apply-discount/scripts/discount.py" SILVER 480

You report:

SILVER tier · −X% off · final $Y.YY
{"tier": "SILVER", "original_amount": 480.0, "discount_pct": ..., "discount_amount": ..., "final_amount": ...}

(The exact percentage and amounts come from the script's output — do not fill them in from memory.)

Rules

• ALWAYS run the script. Never guess the discount.
• Pass the tier name in uppercase; the script normalizes anyway.
• If the script prints {"error": ...} on stderr, surface that error to the user verbatim. Do NOT invent a fallback discount.
