depmap

A research tool for the Cancer Dependency Map, a Broad Institute project that measures which genes cancer cells need and how cancer cells respond to drugs.

In plain words
What is it for?
It is for finding cancer-specific gene weaknesses, possible synthetic-lethal relationships, drug sensitivities, and evidence for oncology targets.
Why use it?
It helps researchers check whether a proposed cancer target matters in particular cancer types instead of relying only on assumptions.

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

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 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.

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:

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)?

Core Concepts

Dependency Scores

Score Range Meaning
Chronos (CRISPR) ~ -3 to 0+ More negative = more essential. Common essential threshold: −1. Pan-essential genes ~−1 to −2
RNAi DEMETER2 ~ -3 to 0+ Similar scale to Chronos
Gene Effect normalized Normalized Chronos; −1 = median effect of common essential genes

Key thresholds:

  • Chronos ≤ −0.5: likely dependent
  • Chronos ≤ −1: strongly dependent (common essential range)

What ships with it

1 file 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.

depmap is a skill published in the GitHub repository magic3007/dotfiles (10 stars, last pushed 6d ago), licensed MIT. It adds 52 tokens to every session and 2,709 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). It is 100% identical to depmap, differing in 0 lines, and is treated as a copy.
