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+).

As of v0.33.0+, the SDK requires Go 1.25 or later (supports the two most recent Go major versions).

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 gRPC
grep "google.golang.org/grpc" go.mod 2>/dev/null
 
# Detect logging libraries
grep -E "sirupsen/logrus|go.uber.org/zap|rs/zerolog|log/slog" go.mod go.sum 2>/dev/null
 
# Detect cron / scheduler patterns
grep -E "robfig/cron|go-co-op/gocron|jasonlvhit/gocron" go.mod 2>/dev/null
 
# Detect OpenTelemetry usage
grep "go.opentelemetry.io" go.mod 2>/dev/null
 
# Check for companion frontend
ls frontend/ web/ client/ ui/ 2>/dev/null

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

# Core SDK (always required)
go get github.com/getsentry/sentry-go
 
# Framework sub-package — install only what matches detected framework:
go get github.com/getsentry/sentry-go/http      # net/http
go get github.com/getsentry/sentry-go/gin       # Gin
go get github.com/getsentry/sentry-go/echo      # Echo
go get github.com/getsentry/sentry-go/fiber     # Fiber
go get github.com/getsentry/sentry-go/fasthttp  # FastHTTP
 
# Logging sub-packages — install only what matches detected logging lib:
go get github.com/getsentry/sentry-go/logrus    # Logrus
go get github.com/getsentry/sentry-go/slog      # slog (stdlib, Go 1.21+)
go get github.com/getsentry/sentry-go/zap       # Zap
go get github.com/getsentry/sentry-go/zerolog   # Zerolog
 
# gRPC interceptors (only if google.golang.org/grpc is detected):
go get github.com/getsentry/sentry-go/grpc
 
# OpenTelemetry bridge (only if OTel is already in use):
go get github.com/getsentry/sentry-go/otel

Quick Start — Recommended Init

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

import (
    "log"
    "os"
    "time"
    "github.com/getsentry/sentry-go"
)
 
err := sentry.Init(sentry.ClientOptions{
    Dsn:              os.Getenv("SENTRY_DSN"),
    Environment:      os.Getenv("SENTRY_ENVIRONMENT"), // "production", "staging", etc.
    Release:          release,                          // inject via -ldflags at build time
    SendDefaultPII:   true,
    AttachStacktrace: true,
 
    // Tracing (adjust sample rate for production)
    EnableTracing:    true,
    TracesSampleRate: 1.0, // lower to 0.1–0.2 in high-traffic production
 
    // Logs
    EnableLogs: true,
})
if err != nil {
    log.Fatalf("sentry.Init: %s", err)
}
defer sentry.Flush(2 * time.Second)

Injecting `Release` at build time (recommended):

var release string // set by -ldflags
 
// go build -ldflags="-X main.release=my-app@$(git describe --tags)"

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:

// net/http, Negroni:
hub := sentry.GetHubFromContext(r.Context())
 
// Gin:
hub := sentrygin.GetHubFromContext(c)
 
// Echo:
hub := sentryecho.GetHubFromContext(c)
 
// Fiber:
hub := sentryfiber.GetHubFromContext(c)

gRPC Integration

For gRPC servers and clients, use the sentrygrpc interceptors instead:

import sentrygrpc "github.com/getsentry/sentry-go/grpc"
 
// Server: register interceptors when creating the gRPC server
server := grpc.NewServer(
    grpc.UnaryInterceptor(sentrygrpc.UnaryServerInterceptor()),
    grpc.StreamInterceptor(sentrygrpc.StreamServerInterceptor()),
)
 
// Client: register interceptors when dialing
conn, err := grpc.NewClient(
    address,
    grpc.WithUnaryInterceptor(sentrygrpc.UnaryClientInterceptor()),
    grpc.WithStreamInterceptor(sentrygrpc.StreamClientInterceptor()),
)
 
// Hub access inside a gRPC handler:
hub := sentry.GetHubFromContext(ctx)

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:

// In a handler or test — triggers a real error event:
sentry.CaptureMessage("Sentry Go SDK test")
 
// Or trigger a captured panic (with recovery middleware in place):
panic("sentry test panic")

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:

ls frontend/ web/ client/ ui/ 2>/dev/null
cat frontend/package.json web/package.json 2>/dev/null | grep -E '"react"|"svelte"|"vue"|"next"'

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