Install on Cursor / Windsurf

1. Clone the Skills repo

git clone https://github.com/ArraysData/arrays-skills.git ~/.arrays-skills

2. Add the Skills as project rules

Cursor
Windsurf (.windsurfrules)

From your project root, run the converter. It writes one .cursor/rules/<skill>.mdc per skill, with the skill description as the rule description:

bash ~/.arrays-skills/scripts/install-cursor.sh

Pass a directory to install somewhere else: bash ~/.arrays-skills/scripts/install-cursor.sh path/to/.cursor/rules.

Windsurf reads a single rules file. In your project root create .windsurfrules:

# Arrays Financial Data

Use the Arrays Skills at ~/.arrays-skills/skills/
when answering questions about market data.

Auth: X-API-Key header, key in ARRAYS_API_KEY env var.
Base: https://data-tools.prd.arrays.org  (skills append /api/v1/...)

3. Set your API key

In your project’s .env (and add .env to .gitignore):

ARRAYS_API_KEY=your_key_here

4. Try it

In Cursor / Windsurf chat, ask:

Show me NVDA's last 4 quarters of free cash flow.

The agent should follow the Arrays Skill, call company/cashflow-statements, and return real data.

Cursor and Windsurf currently can’t auto-execute HTTP calls — they’ll generate the code, and you run it. For a fully automated loop, use Claude Code or Codex.
