Sentry Go SDK

Opinionated wizard that scans your Go project and guides you through complete Sentry setup.

Invoke This Skill When

• User asks to "add Sentry to Go" or "setup Sentry" in a Go app
• User wants error monitoring, tracing, logging, metrics, or crons in Go
• User mentions sentry-go, github.com/getsentry/sentry-go, or Go Sentry SDK
• User wants to monitor panics, HTTP handlers, or scheduled jobs in Go

Note: SDK versions and APIs below reflect Sentry docs at time of writing (sentry-go v0.43.0). Always verify against docs.sentry.io/platforms/go/ before implementing.

Phase 1: Detect

Run these commands to understand the project before making any recommendations:

# Check existing Sentry dependency
grep -i sentry go.mod 2>/dev/null
 
# Detect web framework
grep -E "gin-gonic/gin|labstack/echo|gofiber/fiber|valyala/fasthttp|kataras/iris|urfave/negroni" go.mod 2>/dev/null
 
# Detect logging libraries
grep -E

What to note:

• Is sentry-go already in go.mod? If yes, skip to Phase 2 (configure features).
• Which framework is used? (Determines which sub-package and middleware to install.)
• Which logging library? (Enables automatic log capture.)
• Are cron/scheduler patterns present? (Triggers Crons recommendation.)
• Is there a companion frontend directory? (Triggers Phase 4 cross-link.)

Phase 2: Recommend

Based on what you found, present a concrete recommendation. Don't ask open-ended questions — lead with a proposal:

Recommended (core coverage):

• ✅ Error Monitoring — always; captures panics and unhandled errors
• ✅ Tracing — if HTTP handlers, gRPC, or DB calls are detected
• ✅ Logging — if logrus, zap, zerolog, or slog is detected

Optional (enhanced observability):

• ⚡ Metrics — custom counters and gauges for business KPIs / SLOs
• ⚡ Crons — detect silent failures in scheduled jobs
• ⚠️ Profiling — removed in sentry-go v0.31.0; see references/profiling.md for alternatives

Recommendation logic:

Propose: "I recommend setting up Error Monitoring + Tracing [+ Logging if applicable]. Want me to also add Metrics or Crons?"

Phase 3: Guide

Install

Quick Start — Recommended Init

Add to main() before any other code. This config enables the most features with sensible defaults:

Injecting Release at build time (recommended):

Framework Middleware

After sentry.Init, register the Sentry middleware for your framework:

Note: Fiber and FastHTTP are built on valyala/fasthttp which has no built-in recovery. Use Repanic: false, WaitForDelivery: true for those.

Hub access in handlers:

For Each Agreed Feature

Walk through features one at a time. Load the reference file for each, follow its steps, and verify before moving to the next:

For each feature: Read ${SKILL_ROOT}/references/<feature>.md, follow steps exactly, verify it works.

Configuration Reference

Key ClientOptions Fields

Environment Variables

Options set in ClientOptions override environment variables.

Verification

Test that Sentry is receiving events:

Check the Sentry dashboard within a few seconds. If nothing appears:

1. Set Debug: true in ClientOptions — prints SDK internals to stdout
2. Verify the DSN is correct and the project exists
3. Ensure sentry.Flush(2 * time.Second) is called (events are async by default)

Phase 4: Cross-Link

After completing Go setup, check for a companion frontend missing Sentry coverage:

If a frontend directory exists without Sentry configured, suggest the matching skill:
