visualize

visualize is a skill for Claude Code, Codex from JansenAnalytics/claudex. It costs 31 tokens per session (484 once invoked), scanned B, original, MIT.

A chart-generation tool that turns CSV data into visual formats such as line, bar, scatter, heatmap, and candlestick charts. A candlestick chart shows price movement over time using opening, high, low, and closing values.

In plain words
What is it for?
Use it to create report graphics, plot time series, compare categories, visualize measurements, or display market price data.
Why use it?
It makes trends, comparisons, measurements, and financial data easier to inspect than raw tables.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 scripts/chart.py sales.csv --type line --x month --y revenue -o revenue.png.

Good fit Use it to create report graphics, plot time series, compare categories, visualize measurements, or display market price data.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 B, and why

visualize scanned grade B 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 4d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

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.

visualize is a skill published in the GitHub repository JansenAnalytics/claudex (5 stars, last pushed 2mo ago), licensed MIT. It adds 31 tokens to every session and 484 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root).
