# Agent Lab: edit and validate a chart configuration

> WestCoast Charts 1.1.5, release, public Core release, on npm. HTML: https://westcoast-charts.com/playground/ · Index for agents: https://westcoast-charts.com/llms.txt

The live browser lab uses the pinned Library 1.1.5 directly. It is not a CLI or MCP simulator.

## Validate and correct a configuration

1. Choose daily traffic, night traffic or the free Core lead-outcome chart. Data is invented.
2. Inspect the JSON configuration.
3. Introduce an intentional typo. The library validator reports its exact path and suggested correction.
4. Apply the suggested fixes with WestCoastCharts.applyFixes(), validate again and render.
5. Open Describe to read the actual chart.describe() model, Markdown and table. Ring selections are reflected in that drawn state.

## APIs

Load west-coast-charts/agent/validate and west-coast-charts/agent/describe as optional modules after the core. Call WestCoastCharts.validate(options), WestCoastCharts.applyFixes(options, issues), then chart.describe({format: 'json' | 'table' | 'markdown'}).

## Tooling status

Public agent tools 0.2.3, tested with Library 1.1.5; available from the versioned GitHub release and npm. CLI and MCP syntax on the page is copyable documentation. No server-side tool is invoked. Follow the verified installation channels below.

## Install CLI and MCP
