Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install exchange-trading-session-detection

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent adds session indicators to your time series: open session, lunch break and holidays, for each exchange in your registry. It compares a simple hour-range version with one built on exchange_calendars, which handles daylight saving time. You get a detector ready for production.
