# Tactics Board

> A browser tactics board for football (soccer) coaches. Drills are coloured counters, cones, arrows and text on a pitch, in phases that animate one into the next; sessions run several drills in order. Everything is stored in the coach's browser: there is no server, account or API.

An AI agent can write drills and sessions as one JSON file and hand them to a coach as a link. Opening the link shows the coach what it contains, checks it, and imports it once they confirm.

## Docs

- [Writing drills](/agents.md): the file format (coordinates, phases, players, balls, sessions) and how to build an import link
- [Drill file JSON Schema](/drill.schema.json): the exact shape the import accepts, for structured output
- [Example drills](/demo-drills.json): six valid drills and one session to copy from

## Import link

- `/#import=<base64url of the JSON file, optionally gzipped>`: the drills travel inside the link
- `/?import=<https URL of a JSON file>`: the app fetches the file (the host must allow CORS)
