skills/development/sentry-python-sdk/SKILL.mdSentry Python SDK
Opinionated wizard that scans your Python project and guides you through complete Sentry setup.
Invoke This Skill When
- User asks to "add Sentry to Python" or "setup Sentry" in a Python app
- User wants error monitoring, tracing, profiling, logging, metrics, or crons in Python
- User mentions
,sentry-sdk
, or Sentry + any Python frameworksentry_sdk - User wants to monitor Django views, Flask routes, FastAPI endpoints, Celery tasks, or scheduled jobs
Note: SDK versions and APIs below reflect Sentry docs at time of writing (sentry-sdk 2.x). Always verify against docs.sentry.io/platforms/python/ before implementing.
Phase 1: Detect
Run these commands to understand the project before making recommendations:
# Check existing Sentry grep -i sentry requirements.txt pyproject.toml setup.cfg setup.py 2>/dev/null # Detect web framework grep -rE "django|flask|fastapi|starlette|aiohttp|tornado|quart|falcon|sanic|bottle" \ requirements.txt pyproject.toml 2>/dev/null # Detect task queues grep -rE "celery|rq|huey|arq|dramatiq" requirements.txt pyproject.toml 2>/dev/null # Detect logging libraries grep -E "loguru" requirements.txt pyproject.toml 2>/dev/null # Detect AI libraries grep -rE "openai|anthropic|langchain|huggingface|google-genai|pydantic-ai|litellm" \ requirements.txt pyproject.toml 2>/dev/null # Detect schedulers / crons grep -rE "celery|apscheduler|schedule|crontab" requirements.txt pyproject.toml 2>/dev/null # Check for companion frontend ls frontend/ web/ client/ ui/ static/ templates/ 2>/dev/null
What to note:
- Is
already in requirements? If yes, check ifsentry-sdk
is present — may just need feature config.sentry_sdk.init() - Which framework? (Determines where to place
.)sentry_sdk.init() - Which task queue? (Celery needs dual-process init; RQ needs a settings file.)
- AI libraries? (OpenAI, Anthropic, LangChain are auto-instrumented.)
- Companion frontend? (Triggers Phase 4 cross-link.)
Phase 2: Recommend
Based on what you found, present a concrete proposal. Don't ask open-ended questions — lead with a recommendation:
Always recommended (core coverage):
- ✅ Error Monitoring — captures unhandled exceptions, supports
(Python 3.11+)ExceptionGroup - ✅ Logging — Python
stdlib auto-captured; enhanced if Loguru detectedlogging
Recommend when detected:
- ✅ Tracing — HTTP framework detected (Django/Flask/FastAPI/etc.)
- ✅ AI Monitoring — OpenAI/Anthropic/LangChain/etc. detected (auto-instrumented, zero config)
- ⚡ Profiling — production apps where performance matters
- ⚡ Crons — Celery Beat, APScheduler, or cron patterns detected
- ⚡ Metrics — business KPIs, SLO tracking
Recommendation matrix:
| Feature | Recommend when... | Reference |
|---|---|---|
| Error Monitoring | Always — non-negotiable baseline | |
| Tracing | Django/Flask/FastAPI/AIOHTTP/etc. detected | |
| Profiling | Production + performance-sensitive workload | |
| Logging | Always (stdlib); enhanced for Loguru | |
| Metrics | Business events or SLO tracking needed | |
| Crons | Celery Beat, APScheduler, or cron patterns | |
| AI Monitoring | OpenAI/Anthropic/LangChain/etc. detected | |
Propose: "I recommend Error Monitoring + Tracing [+ Logging if applicable]. Want Profiling, Crons, or AI Monitoring too?"
Phase 3: Guide
Install
# Core SDK (always required) pip install sentry-sdk # Optional extras (install only what matches detected framework): pip install "sentry-sdk[django]" pip install "sentry-sdk[flask]" pip install "sentry-sdk[fastapi]" pip install "sentry-sdk[celery]" pip install "sentry-sdk[aiohttp]" pip install "sentry-sdk[tornado]" # Multiple extras: pip install "sentry-sdk[django,celery]"
Extras are optional — plain
works for all frameworks. Extras install complementary packages.sentry-sdk
Quick Start — Recommended Init
Full init enabling the most features with sensible defaults. Place before any app/framework code:
import sentry_sdk sentry_sdk.init( dsn=os.environ["SENTRY_DSN"], environment=os.environ.get("SENTRY_ENVIRONMENT", "production"), release=os.environ.get("SENTRY_RELEASE"), # e.g. "myapp@1.0.0" send_default_pii=True, # Tracing (lower to 0.1–0.2 in high-traffic production) traces_sample_rate=1.0, # Profiling — continuous, tied to active spans profile_session_sample_rate=1.0, profile_lifecycle="trace", # Structured logs (SDK ≥ 2.35.0) enable_logs=True, )
Where to Initialize Per Framework
| Framework | Where to call | Notes |
|---|---|---|
| Django | Top of , before any imports | No middleware needed — Sentry patches Django internally |
| Flask | Before | Must precede app creation |
| FastAPI | Before | + auto-enabled together |
| Starlette | Before | Same auto-integration as FastAPI |
| AIOHTTP | Module level, before | |
| Tornado | Module level, before app setup | No integration class needed |
| Quart | Before | |
| Falcon | Module level, before | |
| Sanic | Inside | Sanic's lifecycle requires async init |
| Celery | in worker AND in calling process | Dual-process init required |
| RQ | loaded by worker via | |
| ARQ | Both worker module and enqueuing process |
Django example (
settings.py):
import sentry_sdk sentry_sdk.init( dsn=os.environ["SENTRY_DSN"], send_default_pii=True, traces_sample_rate=1.0, profile_session_sample_rate=1.0, profile_lifecycle="trace", enable_logs=True, ) # rest of Django settings... INSTALLED_APPS = [...]
FastAPI example (
main.py):
import sentry_sdk sentry_sdk.init( dsn=os.environ["SENTRY_DSN"], send_default_pii=True, traces_sample_rate=1.0, profile_session_sample_rate=1.0, profile_lifecycle="trace", enable_logs=True, ) from fastapi import FastAPI app = FastAPI()
Auto-Enabled vs Explicit Integrations
Most integrations activate automatically when their package is installed — no
integrations=[...] needed:
| Auto-enabled | Explicit required |
|---|---|
| Django, Flask, FastAPI, Starlette, AIOHTTP, Tornado, Quart, Falcon, Sanic, Bottle | |
| Celery, RQ, Huey, ARQ | |
| SQLAlchemy, Redis, asyncpg, pymongo | |
| Requests, HTTPX, aiohttp-client | |
| OpenAI, Anthropic, LangChain, Pydantic AI, MCP | |

Verification
Test that Sentry is receiving events:
# Trigger a real error event — check dashboard within seconds division_by_zero = 1 / 0
Or for a non-crashing check:
sentry_sdk.capture_message("Sentry Python SDK test")
If nothing appears:
- Set
indebug=True
— prints SDK internals to stdoutsentry_sdk.init() - Verify the DSN is correct
- Check
env var is set in the running processSENTRY_DSN - For Celery/RQ: ensure init runs in the worker process, not just the calling process
Phase 4: Cross-Link
After completing Python setup, check for a companion frontend missing Sentry:
ls frontend/ web/ client/ ui/ 2>/dev/null cat frontend/package.json web/package.json client/package.json 2>/dev/null \ | grep -E '"react"|"svelte"|"vue"|"next"|"nuxt"'
If a frontend exists without Sentry, suggest the matching skill:
| Frontend detected | Suggest skill |
|---|---|
| React / Next.js | |
| Svelte / SvelteKit | |
| Vue / Nuxt | Use — see docs.sentry.io/platforms/javascript/guides/vue/ |
| Other JS/TS | (covers generic browser JS patterns) |
Troubleshooting
| Issue | Solution |
|---|---|
| Events not appearing | Set , verify DSN, check env vars in the running process |
| Malformed DSN error | Format: |
| Django exceptions not captured | Ensure is at the top of before other imports |
| Flask exceptions not captured | Init must happen before |
| FastAPI exceptions not captured | Init before ; both and auto-enabled |
| Celery task errors not captured | Must call in the worker process via signal |
| Sanic init not working | Init must be inside , not module level |
| uWSGI not capturing | Add to uWSGI command |
| No traces appearing | Verify is set (not ); check that the integration is auto-enabled |
| Profiling not starting | Requires + either or |
not working | Requires SDK ≥ 2.35.0; for direct structured logs use ; for stdlib bridging use |
| Too many transactions | Lower or use to drop health checks |
| Cross-request data leaking | Don't use for per-request data — use |
| RQ worker not reporting | Pass to disable RQ's own Sentry shortcut; init via settings file instead |
