An ecommerce business-review skill for direct-to-consumer stores that analyzes order transaction CSV files. It calculates key performance indicators, runs health checks across several time periods, and explains the results in plain language.

It is for producing a full review file or answering a focused question about 30-day, 90-day, or 365-day ecommerce performance.

It separates calculation from interpretation, so raw order data becomes a readable assessment of business performance.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00074	$0.01920
Opus 5.5	$0.00030	$0.00768
Sonnet 5.5	$0.00015	$0.00384
Haiku 4.5	$0.00007	$0.00192

Security

Grade A, and why

ecom scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ecom — Ecommerce Business Review Toolkit

D2C ecommerce analytics. The bundled Python engine computes KPIs, runs health checks, and scores performance from order transaction data; you (Claude) interpret the numbers and write the human-readable report.

Key principle: Python computes the numbers. Claude interprets them. Never present raw numbers without business context.

Arguments: $ARGUMENTS (if empty, infer intent from the conversation)

Mode Selection

Arguments / intent	Mode	Output
empty or `review`	Full Review (auto-selects periods from data)	`REVIEW.md`
`review 30d` / `90d` / `365d`	Full Review, single period	`REVIEW_{PERIOD}.md`
contains a natural-language question	Focused Query	Inline answer, no file

Input

Order transaction CSV. Each row = one order or line item. Required columns: order ID, order date, customer ID (or email), revenue (after discounts, before tax/shipping). Optional: quantity, SKU/product, discount amount. Column names are fuzzy-matched by the loader.

If no CSV is specified, Glob for *.csv in the working directory and ask the user if multiple plausible candidates exist.

Running the Engine

The ecom CLI is on PATH while this plugin is enabled:

ecom review orders.csv --output <output-dir>
ecom review orders.csv --period 90d --output <output-dir>

If ecom is not on PATH, use the bundled launcher with the same arguments: "${CLAUDE_SKILL_DIR}/../../bin/ecom". The first run bootstraps a private Python venv under ~/.local/share/claude-ecom/ and may take a minute; later runs are instant.

Output: review.json (or review_{period}.json for --period runs) in the output directory (defaults to current directory).

Workflow

Phase 1: Compute (Python)

Run the engine (add --period per Mode Selection). It computes, per available period: summary KPIs with prior-period comparison, a new-vs-returning KPI tree, revenue driver decomposition (AOV / volume / mix), and — for 365d — repeat purchase rate and a 12-month monthly_trend. It also evaluates ~30 health checks across Revenue, Customer, and Product; each returns pass / watch / fail and powers the 🟢/🟡/🔴 markers.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
