alterlab-depmap

alterlab-depmap is a skill for Claude Code from AlterLab-IEU/AlterLab-Academic-Skills. It costs 77 tokens per session (3,035 once invoked), scanned A, original, MIT.

A collection of cancer research data from the Cancer Dependency Map, which tests how cancer cell lines respond when genes are removed or drugs are applied. It includes gene dependency scores, drug sensitivity results, and gene-effect profiles.

In plain words
What is it for?
Use it to find genes essential to particular cancers, identify possible drug targets, and study synthetic lethal interactions, where blocking two factors together may harm cancer cells.
Why use it?
It removes the need to download and combine cancer screening datasets manually. It helps compare genetic vulnerabilities across cancer types and cell lines.

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

alterlab-depmap scanned grade A with 1 finding 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 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/query_depmap.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

DepMap — Cancer Dependency Map

Overview

The Cancer Dependency Map (DepMap) project, run by the Broad Institute, systematically characterizes genetic dependencies across hundreds of cancer cell lines using genome-wide CRISPR knockout screens (DepMap CRISPR), RNA interference (RNAi), and compound sensitivity assays (PRISM). DepMap data is essential for:

  • Identifying which genes are essential for specific cancer types
  • Finding cancer-selective dependencies (therapeutic targets)
  • Validating oncology drug targets
  • Discovering synthetic lethal interactions

Key resources:

Access model — read this first. DepMap has no documented, stable public REST API for gene-level queries (the internal depmap.org/portal/api/... paths are undocumented and return 404 for ad-hoc requests — do not script against them). The supported workflow is: download the release matrix CSVs, then analyse them locally with pandas. The keyless programmatic path to those files is the Figshare API (/articles/{id}/files lists name + download_url); scripts/query_depmap.py wraps this.

When to Use This Skill

Use DepMap when:

  • Target validation: Is a gene essential for survival in cancer cell lines with a specific mutation (e.g., KRAS-mutant)?
  • Biomarker discovery: What genomic features predict sensitivity to knockout of a gene?
  • Synthetic lethality: Find genes that are selectively essential when another gene is mutated/deleted
  • Drug sensitivity: What cell line features predict response to a compound?
  • Pan-cancer essentiality: Is a gene broadly essential across all cancer types (bad target) or selectively essential?
  • Correlation analysis: Which pairs of genes have correlated dependency profiles (co-essentiality)?

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.

alterlab-depmap is a skill published in the GitHub repository AlterLab-IEU/AlterLab-Academic-Skills (66 stars, last pushed 6d ago), licensed MIT. It adds 77 tokens to every session and 3,035 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
