tableau-data

tableau-data is a skill for Claude Code from laviDrori0702/tableau-dashboard-creator-skill. It costs 134 tokens per session (2,553 once invoked), scanned A, original, MIT.

A data-preparation step for Tableau dashboard projects. It examines CSV files, documents their field names and types in DATA-MODEL.md, and checks that the documentation matches the CSV headers.

In plain words
What is it for?
Use it to profile analyst-provided CSV data, create the handoff document for later steps, and approve the data structure before planning or building the dashboard.
Why use it?
It prevents later dashboard work from using incorrect or undocumented data fields.

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

tableau-data 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 3d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/constants.py, scripts/data.py, scripts/datamodel.py, …), 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 — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.

tableau-data

Step 3 of 8, and non-skippable. It turns the analyst's data into DATA-MODEL.md — the documented field names and types that tableau-mock and tableau-build build against. The CSVs under data/ are the single source of truth for those field names, so this step also validates that the documented names match the real CSV headers exactly before approving.

Reads The data: production data/*.csv (preferred) or the scaffold/sample-data/*.csv demo fallback. For the published-ds route, the inputs datasources.json + .env (the latter discovered by walking up — nearest wins). None is a required readdata has no producer-gated inputs (CONTRACT.md §1).
Writes DATA-MODEL.md at the project root (latest approved truth; overwritten in place). The CSVs themselves are analyst-provided in data/ (or the demo scaffold/sample-data/).
STATE.md update Sets data = approved; flips every downstream approved step to stale on a re-run (CONTRACT.md §4.2).
Entry gate Refuses to run until init is approved in STATE.md (CONTRACT.md §4.1).
Next step tableau-brand (or tableau-plan, or tableau-route to confirm).

The two acquisition routes (and no third)

There are exactly two ways to get the mimicking CSVs (CONTRACT.md §3.2). There is no synthesized/random-data path — when no real data exists, the floor is the clearly-labelled scaffold/sample-data/ demo, never invented rows.

  • Route 1 — data_mode: csv (default, zero-credential). The analyst drops CSV file(s) in data/. Each CSV is one data source. profile → enrich → commit.
  • Route 2 — data_mode: published-ds (VizQL Data Service). The analyst lists published sources in datasources.json (one entry each: ds_name + project_name) and supplies a Tableau connection in .env. pull signs in with the Personal Access Token and samples each source through the VDS — read-metadata (authoritative field names/types/descriptions) then query-datasource (a capped row sample) — writing one data/<slug>.csv per source plus DATA-MODEL.md. Then enrich → commit, exactly as Route 1. Fires only when data/ has no production CSVs (real CSVs always win).

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.
