Install on Claude Code

Prerequisites

Claude Code installed
An Arrays API key from arrays.org

1. Clone the Skills repo

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

2. Link the Skills into Claude Code

Claude Code discovers skills in ~/.claude/skills/. Symlink each skill there:

mkdir -p ~/.claude/skills
for d in ~/.arrays-skills/skills/arrays-data-api-*/; do
  ln -sfn "$d" ~/.claude/skills/$(basename "$d")
done

Or let the installer detect Claude Code (and any other supported agent) and do the same thing:

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

The links point back into the clone, so git pull in ~/.arrays-skills updates every skill in place.

3. Set your API key

Add to your shell config (~/.zshrc or ~/.bashrc):

export ARRAYS_API_KEY="your_key_here"

ARRAYS_API_BASE_URL is optional and defaults to https://data-tools.prd.arrays.org (no /api suffix — the skills append /api/v1/... themselves). Reload: source ~/.zshrc

4. Try it

In Claude Code, ask:

What was AAPL's revenue and net income last quarter?

Claude should automatically pick the arrays-data-api-equity-fundamentals Skill, call the company/income-statements endpoint, and return real numbers.

Troubleshooting

Claude doesn't seem to use the Skills

Run ls -l ~/.claude/skills/ and confirm the arrays-data-api-* symlinks resolve. Restart Claude Code after installing — skills are discovered at startup.

'Unauthorized' or 401 error

Check echo $ARRAYS_API_KEY is set in the same shell session where Claude Code runs. If you opened Claude Code from a GUI, export the var system-wide or use a .env file at the project root.
