craft-data

A set of data-engineering skills for reviewing data pipelines, improving slow SQL queries, defining data agreements, and practicing technical interviews. A data pipeline moves and transforms data between systems; SQL is the language used to query databases.

In plain words
What is it for?
Use it to audit workflows for issues such as late data or schema changes, inspect query plans, create producer-consumer data contracts and tests, and run scored mock interviews.
Why use it?
It helps find silent pipeline failures, verify that query changes improve performance, prevent incompatible data changes, and identify interview weaknesses.

Grade A, and why

craft-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 2d 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 it installs

The manifest is a name and a version. 4 skills travel with it, and installing the plugin installs all of them — 437 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.

craft-data is a plugin published in the GitHub repository Tasachii/Tasachii-Tools (2 stars, last pushed 1mo ago), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. 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 2026-08-31.
