Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads supplier-selection automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

Supplier Selection
Ranking suppliers is arithmetic, not judgment. Compute it in Python via code execution — do not reason about it in prose.
Method
For a given SKU:
- Read
/mnt/user/data/supplier_catalog.csvand filter to rows matching the SKU. This gives you(supplier_id, unit_price, min_order_qty)for each candidate. - Join with
/mnt/user/data/suppliers.csvonsupplier_idto getlead_time_daysandreliability. - Normalize price and lead time across the candidates (min-max to [0,1], where 0 is best). Reliability is already on [0,1] where higher is better.
- Score each candidate:
score = 0.5 × (1 − norm_price) + 0.3 × (1 − norm_lead_time) + 0.2 × reliability - Pick the highest score. Tie-breaks: lowest
unit_price, then lowestlead_time_days, then alphabeticalsupplier_id.
Do this in code
Write and run a short Python script — don't call a tool per supplier, and don't compare quotes by describing them. Example shape:
import csv
sku = "SKU-0057"
catalog = [r for r in csv.DictReader(open("/mnt/user/data/supplier_catalog.csv")) if r["sku"] == sku]
suppliers = {r["supplier_id"]: r for r in csv.DictReader(open("/mnt/user/data/suppliers.csv"))}
# join, normalize, score, sort — print the winner as JSON
Supplier-specific overrides
These quirks are not in the catalog data. Apply them after computing the score; if one changes your pick, say so in the rationale.
| Supplier | Override |
|---|---|
| SUP-01 Cascade Distribution | Orders >500 units need 48h notice or they auto-split into two shipments — add to lead-time math for large POs. |
| SUP-02 Alpine Wholesale | Closed Dec 20 – Jan 3. POs in that window aren't acknowledged until Jan 4. Land holiday replenishment before Dec 15. |
| SUP-03 Backcountry Supply Co | Two short-ships on Tents & Shelter this year. Prefer an alternate for that category if lead is comparable. |
| SUP-04 Sierra Outfitters | Unlisted 3% price break at 250+ units. If recommended qty is 200–249, often worth rounding up. |
| SUP-05 Granite Gear Partners | West-coast DC only. Add 2–3 days to catalog lead time for WH-EAST deliveries. |
| SUP-07 Ridgecrest Imports | Import-only; lead times are port-congestion sensitive. Don't rely on stated lead for an urgent order. |
| SUP-09 Summit Source | MOQ is enforced strictly — they reject (not round up) below-MOQ POs. |
| SUP-12 Trailhead Mercantile | New on roster. Treat reliability as one notch lower than stated until 6 months of history. |
Warehouse lead-time adjustments
- WH-WEST (Reno): most suppliers ship from east-coast DCs — add +2 days to catalog lead time as a rule of thumb unless a supplier note says otherwise.
- WH-EAST (Carlisle): two-shift receiving dock; best destination for an expedited PO that needs same-day inbound scheduling.
- WH-CENTRAL (Kansas City): overflow / transfer hub. If you're sourcing an inter-warehouse transfer rather than a PO, WH-CENTRAL is almost always the origin.
Expedite override
If the reorder-policy skill flagged expedite, ignore the score and pick the supplier with the lowest lead_time_days whose min_order_qty ≤ your target order qty.
Output
Return {"supplier_id": "SUP-03", "unit_price": 21.40, "lead_time_days": 7, "score": 0.81} and use that supplier_id in the PO.
