Automated summary

Activates a team of ten ML and data analysis specialists via slash commands, each with domain-specific checklists and quality standards.

Strengths

  • Covers the full analysis pipeline from initial question to reproducible delivery.
  • Each mode embodies a distinct expert persona with rigorous evaluation criteria.
  • Encourages cross-critique between agents to eliminate blind spots.

Limitations

  • Requires prior knowledge of ML and statistics concepts to use each mode effectively.
  • Can be slow if all modes are run sequentially on large datasets.
  • Relies on the AI's ability to correctly assess statistical assumptions.
When to use it

Best for structuring an end-to-end data analysis or ML project with systematic reviews at every stage.

When not to use it

Not recommended for simple queries or exploratory work that does not require deep methodological rigor.

Security analysis

Safe
Quality score90/100

The skill defines a catalog of data analysis personas and checklists. It uses allowed-tools (Bash, Read, Write, etc.) but does not instruct destructive actions, data exfiltration, or bypass of safety. It is purely advisory.

mlstack: ML & Data Analysis Team

Ten specialist modes for rigorous data analysis. Use the slash command to activate a mode.

Available Commands

| Command | Role | Use when... | |---------|------|-------------| | /plan-science-review | Principal Investigator | Starting a new analysis — challenge the question before touching data | | /plan-stats-review | Biostatistician | Locking in methodology — assumptions, power, validation strategy | | /plan-ml-review | ML Architect | Choosing a modeling approach — architecture, representations, training dynamics, compute | | /review-notebook | Methods Reviewer | Before sharing/submitting — catch leakage, p-hacking, assumption violations | | /eda | Senior Data Analyst | Exploring a new dataset — systematic profiling with structured output | | /feature-eng | ML Engineer | Creating features — domain rationale, leakage detection, selection | | /model-critique | Research Scientist | After modeling — adversarial evaluation of every methodological choice | | /review-perf | ML Performance Engineer | After implementation — GPU util, dataloader throughput, precision, memory, speed | | /retro-analysis | Analytics Manager | Weekly reflection — notebook quality, methodology rigor, insight yield | | /ship-analysis | Release Analyst | Packaging for delivery — reproducibility, environment freeze, summary |

Quick Start

/plan-science-review    → "Is this the right question?"
/plan-stats-review      → "Is the methodology sound?"
/plan-ml-review         → "Is this the right model for this data?"
/eda data/train.csv     → Structured exploration notebook
/feature-eng --target y → Domain-aware features with leakage audit
/model-critique         → "Was this actually the best approach?"
/review-perf            → "Why is the GPU 40% idle?"
/review-notebook        → Pre-submission methodology check
/ship-analysis          → Package reproducible deliverable
/retro-analysis          → Weekly analytics retrospective

Key Design Principles

  1. Agents critique each other. The model critique agent will challenge recommendations from the stats reviewer. The notebook reviewer will flag issues the EDA missed. No blind spots survive the pipeline.

  2. Every choice needs rationale. No "I used XGBoost because it usually wins." Every method, every feature, every preprocessing step must have a documented justification.

  3. Assumptions are first-class objects. Every statistical method has assumptions. Every assumption gets a diagnostic check. Every failed check gets a fallback plan.

  4. Leakage paranoia. Data leakage is checked at every stage: feature engineering, preprocessing, validation splits, metric computation. One leaky step invalidates everything downstream.

  5. Notebooks tell stories. Every code cell has narrative context. Every result has interpretation. A non-technical reader should understand the story from markdown cells alone.

  6. Reproducibility is mandatory. Random seeds, environment locks, deterministic pipelines, portable paths. An analysis that can't be reproduced can't be trusted.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/mlstack-ml-data-analysis-team-ms1aw3rt/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/mlstack-ml-data-analysis-team-ms1aw3rt' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/mlstack-ml-data-analysis-team-ms1aw3rt/download' --output '.skill-downloads/mlstack-ml-data-analysis-team-ms1aw3rt/SKILL.md.part' && mv '.skill-downloads/mlstack-ml-data-analysis-team-ms1aw3rt/SKILL.md.part' '.skill-downloads/mlstack-ml-data-analysis-team-ms1aw3rt/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

Claude Code
test -f '.skill-downloads/mlstack-ml-data-analysis-team-ms1aw3rt/SKILL.md' && test -s '.skill-downloads/mlstack-ml-data-analysis-team-ms1aw3rt/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/mlstack' && cp -R '.skill-downloads/mlstack-ml-data-analysis-team-ms1aw3rt' '.claude/skills/mlstack'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/mlstack-ml-data-analysis-team-ms1aw3rt'

openskills read 'mlstack-ml-data-analysis-team-ms1aw3rt'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/mlstack-ml-data-analysis-team-ms1aw3rt/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
