accessibility-aggregation

accessibility-aggregation is a skill for Claude Code from ammawla/encode-toolkit. It costs 85 tokens per session (3,846 once invoked), scanned A, original, AGPL-3.0.

A bioinformatics workflow for mapping open regions of chromatin, the DNA packaging inside cells. It combines peak data from ATAC-seq and DNase-seq experiments across samples, donors and laboratories into one shared set of regions.

In plain words
What is it for?
Use it to identify where chromatin is accessible in a tissue by combining ENCODE narrowPeak files into a union peak set.
Why use it?
It reduces the need to inspect many sequencing experiments separately and helps account for differences between studies and labs.

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

accessibility-aggregation 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/validate_peaks.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.

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.

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.

accessibility-aggregation is a skill published in the GitHub repository ammawla/encode-toolkit (21 stars, last pushed 26d ago), licensed AGPL-3.0. It adds 85 tokens to every session and 3,846 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
