Tako Knowledge Search & Visualization

Setup

Read your credentials from ~/.gooseworks/credentials.json:

export GOOSEWORKS_API_KEY=$(python3 -c "import json;print(json.load(open('$HOME/.gooseworks/credentials.json'))['api_key'])")
export GOOSEWORKS_API_BASE=$(python3 -c "import json;print(json.load(open('$HOME/.gooseworks/credentials.json')).get('api_base','https://api.gooseworks.ai'))")

If ~/.gooseworks/credentials.json does not exist, tell the user to run: npx gooseworks login

All endpoints use Bearer auth: -H "Authorization: Bearer $GOOSEWORKS_API_KEY"

Search for data with natural language and get interactive charts, AI-generated insights, and embeddable knowledge cards. Covers finance, economics, demographics, sports, politics, climate, and health from sources like S&P Global, World Bank, and more.

When to Use

  • User wants to compare metrics ("Tesla vs Ford market cap")
  • User needs a chart or visualization for a report
  • User wants to turn their own data into a chart
  • User asks for insights or analysis on a data trend

Tips

  • Knowledge Search is the main endpoint — start here for any data question
  • Use image_url to display charts in Slack, Discord, or other channels
  • embed_url gives an interactive iframe for web pages
  • Call List Default Schemas before Create Card to see available chart types
  • Set search_effort: "deep" for complex multi-metric comparisons
  • Data coverage: stock prices, revenue, GDP, unemployment, population, sports stats, weather, health, and more

Error Handling

  • 400 - Invalid body or missing required fields
  • 401 - Invalid API key
  • 404 - Card not found (Chart Insights) or no results found (Knowledge Search)
  • Empty knowledge_cards array — try rephrasing or using source_indexes: ["tako", "web"]

How to use it

Copy the folder

Take gooseworks-ai/data-charts-tako from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npx. Without those the skill loads but fails at the first command.
