What is data-max CLAUDE.md?

A set of instructions for data-max, a Claude Code plugin containing skills for data-related work. It explains the plugin and marketplace files, skill layout, naming, and installation commands.

Use it when modifying data-max skills, manifests, references, installation instructions, or the marketplace structure.

It clarifies how the plugin is packaged and invoked, including the distinction between plugin and marketplace names. This prevents agents from editing the wrong files or using incorrect command names.

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	$0.00859	$0.00859
Opus 5.5	$0.00344	$0.00344
Sonnet 5.5	$0.00172	$0.00172
Haiku 4.5	$0.00086	$0.00086

Security

Grade A, and why

data-max CLAUDE.md 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.

What this repo is

This is a Claude Code plugin for working with data, published as a single-plugin marketplace — not an application. There is no build step, no test runner, and no runtime. "Shipping" means: edit a SKILL.md (or its supporting files), keep the manifests valid, commit, and push. Installers pull the result via /plugin marketplace add insanetic/data-max, then /plugin install data-max@data-max.

The marketplace name (in marketplace.json) and the plugin name (in plugin.json) are both data-max — so data-max@data-max (<plugin>@<marketplace>) is correct, not a typo. Skills are invoked as /data-max:<skill> (/<plugin>:<skill>).

Layout

.claude-plugin/marketplace.json   ← the marketplace manifest; lists the one plugin (data-max)
.claude-plugin/plugin.json        ← the data-max plugin manifest
skills/<skill>/SKILL.md            ← the skill itself (auto-discovered, no path config needed)
skills/<skill>/references/         ← progressive-disclosure docs, loaded on demand
skills/<skill>/scripts/            ← executable helpers a skill may run (none yet)

One plugin (data-max) ships three skills that form a data lifecycle:

data-review — reviews a raw data file (CSV/TSV/JSON/XML/Excel) for warehouse readiness and produces a tiered cleansing report. Reviews only; never touches the data.
data-transform — consumes a data-review report and produces the cleaned, warehouse-ready CSV(s) via a rerunnable script under tools/. data-review → data-transform is a deliberate two-step pipeline (the report is the spec), not interchangeable.
metric-creator — authors versioned, DSL-compatible metric (data cube) and dimension definitions as copy-pasteable JSON, driven by a DDL schema the user provides. Stands on its own.

The skill name is also what users type after /data-max: — e.g. /data-max:data-review. The data- prefix on the pair is deliberate: it keeps them in the same "data file / data model" context and avoids a bare review (which could read as reviewing a metric).

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.
