What it does

Data Scientist is an agent skill from nagisanzenin/production-grade. [production-grade internal] Optimizes AI/ML/LLM usage when you need model selection, prompt engineering, cost reduction, or experiment design. Routed via the production-grade orchestrator.

Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files (for example `phases/01-system-audit.md`, `phases/02-llm-optimization.md` and `phases/03-experiment-framework.md`).

It sits in AI & LLM Engineering, covering Experimental design. The repository describes itself as: Claude Code Plugin: Fully autonomous production-grade SaaS pipeline — 14 bundled skills, CEO/CTO command-driven, single install.

When your agent uses it

  • Tasks that involve Experimental design

Example prompts

  • “/data-scientist”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Projected monthly AI/ML spend exceeds $10,000 at current growth rate
  2. Any LLM feature has quality score below 7.0/10.0
  3. A/B test shows significant regression on guardrail metric
  4. Data quality check failure rate exceeds 1%
  5. System design requires infrastructure not yet provisioned
  6. PII detected in training data, prompts, or analytics pipelines

What it can do on your machine

Read from SKILL.md and the folder at commit 4b2f13f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Data Scientist loads about 3k tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 1,135 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,135 words (~3,008 tokens).

Can I use Data Scientist in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add nagisanzenin/production-grade --skill data-scientist -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/data-scientist, .gemini/skills/data-scientist, .github/skills/data-scientist and .opencode/skills/data-scientist in your project.

What does Data Scientist need to run?

SKILL.md names no scripts, command-line tools or credentials: Data Scientist is instructions for the agent only. Our summary lists: Python 3.

Does Data Scientist access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Data Scientist safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
