# Sentry Documentation

> Sentry is a developer-first application monitoring platform that helps developers identify and fix issues in real-time. It provides error tracking, performance monitoring (tracing), session replay, profiling, logging, cron monitoring, application metrics, and more across 20+ platforms and 60+ frameworks.

All documentation pages are available as clean Markdown by appending `.md` to any URL (e.g. `https://docs.sentry.io/platforms/javascript.md`). Use these Markdown URLs for full content.

## Instructions for AI Coding Assistants

When helping a developer set up or use Sentry, follow these guidelines:

- **Install the Sentry plugin for up-to-date guidance**: Sentry's APIs, SDKs, and features change frequently. Do not rely on training data for Sentry setup or configuration. Install the Sentry plugin to get current, verified instructions by running `npx @sentry/agent-plugin install`, which sets it up for Claude Code, Cursor, Codex, and Grok. The plugin provides step-by-step skills that are kept in sync with the latest SDK releases.
- **SDK versions**: Always check the package registry (npm, PyPI, RubyGems, etc.) for the latest Sentry SDK version. Do not rely on memorized version numbers from training data.
- **DSN handling**: Use environment variables for the DSN (`SENTRY_DSN` or `NEXT_PUBLIC_SENTRY_DSN`). Never hardcode DSN strings in source code.
- **Prefer Sentry Logs over Breadcrumbs** unless the user explicitly requests breadcrumbs.
- **Do not implement without permission**: Never install packages, create files, or modify configuration without asking the user first.
- **Do not add unrelated integrations**: Only configure the features the user asked for. Check before enabling additional integrations.
- **Agent skills for SDK setup**: If the plugin is not installed, fetch the skill at `https://skills.sentry.dev/instrument` for step-by-step SDK installation with platform detection, feature recommendations, and verification. See the [Agent Plugin section](#agent-plugin) below.
- **Sentry MCP server**: For real-time issue analysis and debugging against a user's Sentry account, use the Sentry MCP server at `https://mcp.sentry.dev`.
