shopify-admin-return-cost-attributionRead-only: calculates the true cost of returns by reason and product — refund dollars, restocking impact, shipping cost lost, and COGS impact for items written off.
Shopify Admin Return Cost Attribution is an agent skill from 40RTY-ai/shopify-admin-skills. Read-only: calculates the true cost of returns by reason and product — refund dollars, restocking impact, shipping cost lost, and COGS impact for items written off.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Claude Code, Cursor, Codex, Gemini CLI
It works with Shopify. The repository describes itself as: Community-maintained AI agent skills for operating Shopify stores — workflows, optimization, reports and more. The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 6765cb4. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:

Names no API keys, tokens, secrets or passwords.

Shopify Admin Return Cost Attribution loads about 1.9k tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 458 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/shopify-admin-return-cost-attribution/SKILL.md (or your agent's skills folder).Quantifies the full cost of returns over a window — not just the refunded amount. Combines refund totals, lost shipping revenue, COGS for non-restockable items (e.g., DEFECTIVE), and restocking labor into a per-reason and per-product return P&L. Read-only. Use to prioritize which reasons or product lines deserve operational fixes — better packaging, size guides, listing accuracy.

ℹ️ Read-only skill — no mutations are executed. Cost figures are estimates derived from
unitCost, refund totals, andflat_restocking_cost— calibrate the flat-cost figure to your operation before treating outputs as accounting truth.
OPERATION: returns — query
Inputs: query: "created_at:>='<NOW - days_back days>'", first: 250, select returns with line item pricing, product/variant, inventoryItem.id
Expected output: All returns in window with per-line-item pricing
OPERATION: orders — query
Inputs: For each return's order.id, fetch refunds { totalRefundedSet refundLineItems { quantity subtotalSet totalTaxSet lineItem { id } } }
Expected output: Refund amounts mappable to line items
OPERATION: inventoryItems — query — batch unique inventoryItem.id from step 1; returns unitCost per item
Per line item compute: refund_amount (matched refundLineItem proportional to returned qty), shipping_loss (order shipping × line-item value share for full-order returns; else 0), cogs_writeoff (unitCost × qty only if returnReason in writeoff_reasons), restocking_labor (flat_restocking_cost × qty). Sum and aggregate by group_by.

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Shopify Admin Return Cost Attribution is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.9k tokens (SKILL.md is roughly 7.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
