skill-022

skill-022 is a skill for Claude Code, Codex from legendtkl/agentic-skill-router. It costs 25 tokens per session (572 once invoked), scanned A, original, MIT.

A guide for building maps in D3.js, a JavaScript library for creating data-driven web graphics, with data tied to places or regions.

In plain words
What is it for?
Use it to create static or interactive maps, such as regional population, sales, weather, or resource-distribution views.
Why use it?
It provides a way to show where data is located and how values differ across geographic areas.

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

skill-022 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 7d 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.

D3.js Map Visualization Skill

This skill enables the creation of geographical visualizations using D3.js. It focuses on rendering maps and spatial relationships to effectively display data that has a geographical context, such as demographics, weather patterns, or resource distribution.

When to use

Activate this skill when the user needs assistance with:

  • "Visualize geographical data on a map"
  • "Create a choropleth map"
  • "Show spatial data relationships"
  • "Map data distributions across regions"

If the user requires non-geographical visualizations, don’t use this skill—opt for the D3.js Visualization Skill instead.


Inputs you should expect

  • One or more local data files: *.json, *.csv with geographical coordinates or region data
  • Mapping requirements:
    • Geographical boundaries (geoJSON topology)
    • Data attributes to bind to regions (e.g., population, sales)
    • Visualization preferences (color scales, legend)
  • Output constraints:
    • Specific mapping styles (e.g., interactive vs. static maps)

If details are missing, make reasonable defaults and document them in comments near the top of the output file.


Outputs you should produce

Prefer producing all of the following when feasible:

  1. dist/map.html — standalone HTML that renders the map visualization
  2. dist/map.svg — exported SVG representation of the map
  3. (Optional) dist/map.png — raster image output if specified

Always keep outputs in a predictable folder (default: dist/), unless the task specifies paths.


Mapping principles (non-negotiable)

To create effective map visualizations:

Geospatial accuracy

  • Ensure that the geographical data used is accurate and up-to-date for reliable representations.
  • Handle data projections appropriately to maintain shape integrity on the map.

User experience

  • Provide interactive features such as zooming and panning to allow users to explore map details.
  • Include tooltips for additional contextual information on hover or click.

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.
