Agent request

Review the Skillstore skill "async-python-patterns" from https://skillstore.io/skills/sickn33-async-python-patterns.md and its manifest at https://skillstore.io/api/skills/sickn33-async-python-patterns/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "async-python-patterns". A synchronous service calls three APIs before responding.

Expected outcome:

Recommended pattern: create bounded concurrent tasks with shared timeout budgets.
Add per-request error handling so one failed call does not hide other results.
Test timeout and cancellation paths with async-aware tests.

Using "async-python-patterns". A scraper starts hundreds of requests at once.

Expected outcome:

Recommended pattern: use semaphores and connection pooling to cap active requests.
Add backpressure so new work waits when the queue is full.
Record failures separately from successful responses for retry decisions.

Using "async-python-patterns". An async test sometimes hangs.

Expected outcome:

Recommended checks: missing await, blocking calls, and tasks that ignore cancellation.
Add explicit timeout assertions and cleanup checks.
Verify that background tasks finish before the test ends.

Security Audit

Medium Risk

v4 • 7/5/2026 Open versioned report

Most static findings are false positives: markdown examples with placeholder URLs, task construction, and inline-code file paths. One semantic issue remains: the async database example builds SQL with f-strings around user_id, which can teach unsafe query construction. No prompt injection, hidden command execution, or data exfiltration intent was found.

Insecure SQL String Interpolation in Database Example

The async database example builds SQL statements with f-strings that include user_id. Even as documentation, this can teach SQL injection-prone query construction.

Lines 445-447 directly interpolate user_id into SELECT statements. The client is simulated, so the risk is unsafe guidance, not malware.

What You Can Build

Build Async APIs

Design request handlers, background tasks, and timeout rules for non-blocking Python services.

Process I/O Workloads

Use queues, semaphores, batching, and connection pools for concurrent network or database tasks.

Test Async Behavior

Create async tests that cover successful work, failures, timeouts, and cancellation paths.

Try These Prompts

Identify Async Fit

Review this Python workflow and tell me whether asyncio is appropriate. Separate I/O-bound tasks from CPU-bound tasks and note runtime constraints.

Refactor Blocking I/O

Convert this synchronous I/O workflow into an asyncio design. Include tasks, awaits, timeouts, and error handling.

Design Concurrency Controls

Design an async processing pipeline for these inputs. Add queue limits, semaphores, cancellation rules, and retry boundaries.

Audit Production Async Code

Review this async Python service for event loop blocking, leaked tasks, missing awaits, weak cancellation, and missing tests. Prioritize risks.

Best Practices

Define timeouts, cancellation behavior, and concurrency limits before adding new async tasks.
Use async-native I/O libraries and parameterized database queries; offload blocking work only when needed.
Test success, failure, timeout, and cancellation paths with async-aware test tools.

Avoid

Do not use asyncio for CPU-bound work unless you offload it to a process or thread pool.
Do not create unbounded tasks without rate limits, queue limits, or backpressure.
Do not call blocking functions inside async code unless they run outside the event loop.

Frequently Asked Questions

What does this skill help me build?

It helps design async Python APIs, services, scrapers, queues, and tests that use asyncio patterns.

Does it execute network requests?

No. It is documentation guidance. Network URLs appear only inside examples.

Which Python versions fit these patterns?

The examples target modern asyncio usage, especially Python 3.7 and newer.

Can I use it with FastAPI or aiohttp?

Yes. The guidance fits async frameworks that run on Python event loops.

Does it include production-ready database code?

No. Treat database examples as simplified patterns and use parameterized queries in production.

Is it suitable for CPU-heavy workloads?

Not by itself. CPU-heavy work usually needs multiprocessing, native extensions, or executor offloading.
