# Squasher Documentation

Squasher is AI-native error monitoring and observability with SDK ingestion, log connectors, OpenTelemetry ingest, AI triage, session replay, status monitoring, on-call coverage, dashboards, automations, a public REST API, a CLI, and a hosted MCP server.

Use this file as the AI-agent entry point for Squasher docs. Prefer public product contracts only: docs pages, OpenAPI, CLI behavior, MCP Code Mode operation schemas, and SDK APIs.

## Agent rules

- Use MCP `search` before `execute`.
- Use bounded time windows for telemetry queries.
- Use `query-guide` before choosing logs, metrics, traces, AI observations, monitors, or incidents.
- For frontend performance checks, start with Web Vitals summary, then segment with Web Vitals breakdown by page, geography, browser, device, campaign, user, or trace.
- Ask before write, destructive, credential rotation, hosted run dispatch, or incident state changes.
- Use `onCall.getCurrentEngineer`, `onCall.listSchedules`, and `onCall.listShifts` before changing on-call schedules; MCP remains Code Mode only with `search("onCall")` and `execute`.
- Never expose real API keys.
