rp-source-csv

rp-source-csv is a skill for Claude Code from wix/skills. It costs 61 tokens per session (6,658 once invoked), scanned A, original, MIT.

A reference guide for importing product data from CSV files, which are plain-text tables commonly used for exports. It covers reading files, identifying ecommerce vendors, grouping rows into entities, and handling sets of files.

In plain words
What is it for?
Use it during discovery to profile CSV files and identify vendors, or during code generation to create readers that group and extract product data correctly.
Why use it?
It keeps CSV-specific import rules separate from the rest of a migration system. This helps generated readers interpret vendor exports consistently, including differences between empty and missing data.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash tests/run-all.sh source-csv.

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.

Security

Grade A, and why

rp-source-csv 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 4d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (lib/canonical-record.js, lib/csv-fileset.js, lib/csv-fingerprint.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 482 lines — stays where its author put it; the contents beside it link to each section on GitHub.

rp-source-csv

CSV source adapter. Owns every CSV-specific detail the platform-agnostic skills must not hardcode: how to parse a file, how to identify which vendor produced it, how its rows group into entities, how a set of files resolves into entity streams, and what a generated reader must get right.

When this skill is used

This is not a stage in the migration flow — it is a reference consulted by two stages:

  • rp-discovery consults the Capture section to sample the files and produce the canonical source-profile.md + source-schema.json.
  • rp-import-codegen consults the Read contract section to generate a reader that extracts CSV data correctly (grouping, derived entities, empty-vs-absent) into durable project-local files for the later import step.

rp-execute-import never consults this skill — by the time execution runs, the CSV-specific knowledge is already baked into the generated reader.

Platform identity

  • Source platform: csv — a file-provided flow, not a URL probe.
  • Set "platform": "csv" in the emitted source-schema.json, and record the detected vendor per file in sourceMeta.vendor / sourceMeta.sourceFiles[].
  • Record sourcePlatform=csv, sourceMode=files_only, and every input file in fileInputPaths in orchestration/decisions.json. Preflight requires no source env keys for csv; the files_only branch enforces a non-empty fileInputPaths instead.

Three layers

  1. A generic core — lib/csv-parse.js (parse, dialect detection, type sniffing) and lib/csv-layout.js (layout inference, derived entities). Knows nothing about commerce and handles any CSV, including hand-rolled ones.
  2. Per-vendor overlays — declarative JSON profiles under vendors/ that specialize the core with a vendor's fingerprint anchors, known layout, column→Wix pre-map, and quirks. v1 ships shopify, woocommerce, magento, bigcommerce.
  3. A fingerprint detector — lib/csv-fingerprint.js picks the overlay from the header set, or honors a user-stated vendor, and falls back to custom below the threshold.

rp-source-csv is a skill published in the GitHub repository wix/skills (36 stars, last pushed yesterday), licensed MIT. It adds 61 tokens to every session and 6,658 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
