lamindb

lamindb is a skill for Claude Code, Codex from thesecondfox/skill. It costs 135 tokens per session (3,272 once invoked), scanned A, a copy of lamindb, MIT.

A Python-based system for storing and managing biological datasets, such as single-cell sequencing and imaging data, with searchable descriptions and records of how the data was produced.

In plain words
What is it for?
Use it to organize biological datasets, validate and label them consistently, and track notebooks, scripts, and analysis pipelines.
Why use it?
It helps teams find the right data, track changes and analysis steps, and make results easier to reproduce and reuse.

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

lamindb 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.

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.

LaminDB

Overview

LaminDB is an open-source data framework for biology designed to make data queryable, traceable, reproducible, and FAIR (Findable, Accessible, Interoperable, Reusable). It provides a unified platform that combines lakehouse architecture, lineage tracking, feature stores, biological ontologies, LIMS (Laboratory Information Management System), and ELN (Electronic Lab Notebook) capabilities through a single Python API.

Core Value Proposition:

  • Queryability: Search and filter datasets by metadata, features, and ontology terms
  • Traceability: Automatic lineage tracking from raw data through analysis to results
  • Reproducibility: Version control for data, code, and environment
  • FAIR Compliance: Standardized annotations using biological ontologies

When to Use This Skill

Use this skill when:

  • Managing biological datasets: scRNA-seq, bulk RNA-seq, spatial transcriptomics, flow cytometry, multi-modal data, EHR data
  • Tracking computational workflows: Notebooks, scripts, pipeline execution (Nextflow, Snakemake, Redun)
  • Curating and validating data: Schema validation, standardization, ontology-based annotation
  • Working with biological ontologies: Genes, proteins, cell types, tissues, diseases, pathways (via Bionty)
  • Building data lakehouses: Unified query interface across multiple datasets
  • Ensuring reproducibility: Automatic versioning, lineage tracking, environment capture
  • Integrating ML pipelines: Connecting with Weights & Biases, MLflow, HuggingFace, scVI-tools
  • Deploying data infrastructure: Setting up local or cloud-based data management systems
  • Collaborating on datasets: Sharing curated, annotated data with standardized metadata

Core Capabilities

LaminDB provides six interconnected capability areas, each documented in detail in the references folder.

1. Core Concepts and Data Lineage

Core entities:

  • Artifacts: Versioned datasets (DataFrame, AnnData, Parquet, Zarr, etc.)
  • Records: Experimental entities (samples, perturbations, instruments)
  • Runs & Transforms: Computational lineage tracking (what code produced what data)
  • Features: Typed metadata fields for annotation and querying

What ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
