Build Reliable Backend Services

Backend projects require consistent choices across APIs, databases, security, performance, and deployment. This skill provides structured workflows, checklists, commands, and FastAPI examples.

Install with my Agent

Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request
Review the Skillstore skill "backend-developer" from https://skillstore.io/skills/zl2023github-backend-developer.md and its manifest at https://skillstore.io/api/skills/zl2023github-backend-developer/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 "backend-developer". Plan a customer orders API for a small FastAPI service.

Expected outcome:

A staged design covering routes, request validation, order states, database tables, indexes, transaction boundaries, errors, tests, and deployment checks.

Using "backend-developer". Investigate an API that becomes slow during traffic spikes.

Expected outcome:

A ranked diagnosis plan using traces, query timing, pool metrics, external call latency, caching checks, load tests, and rollback criteria.

Using "backend-developer". Review a service before its first production deployment.

Expected outcome:

A prioritized readiness report covering secrets, probes, graceful shutdown, resource limits, logging, backups, dependency scans, and unresolved risks.

Security Audit

Medium Risk
v4 • 7/24/2026 Open versioned report

All 33 static detections are false positives caused by Markdown formatting, local example URLs, safe device output, or ordinary technical prose. One semantic issue remains: the FastAPI example exposes raw exception details in client responses.

Verbose Exception Disclosure
The FastAPI example returns raw exception text to clients, which can expose internal details or sensitive values.
The response directly places str(exc) in the client-visible message. This is a clear information disclosure pattern in the supplied example.

What You Can Build

Design a new API

Create an implementation plan with endpoints, validation, data models, indexes, errors, and tests.

Review database performance

Analyze slow queries, execution plans, indexes, pagination, connection pools, and transaction boundaries.

Prepare production deployment

Check probes, shutdown behavior, resources, logs, secrets, backups, and rollback readiness.

Try These Prompts

Plan a backend feature
Design a backend plan for [feature]. Ask about language, framework, database, deployment, data volume, and concurrency before proposing the architecture.
Design an API and data model
Create endpoints and a data model for [workflow]. Include validation, authorization, error responses, indexes, transactions, pagination, and focused tests.
Diagnose a production bottleneck
Analyze [symptoms] using [logs and metrics]. Rank likely causes, propose measurements, identify safe commands, and define rollback criteria before changes.
Review service readiness
Review [service context] for security, performance, reliability, and deployment readiness. Produce prioritized findings, concrete fixes, verification steps, and unresolved risks.

Best Practices

  • Provide business requirements, expected traffic, data volume, framework, database, and deployment environment.
  • Review every command and planned change against the target environment before execution.
  • Verify recommendations with focused tests, query plans, metrics, security checks, and rollback steps.

Avoid

  • Do not request implementation before defining requirements, scale, data ownership, and failure behavior.
  • Do not run example commands against production without confirming scope, permissions, impact, and rollback.
  • Do not expose raw exceptions, secrets, credentials, or sensitive records in logs and responses.

Frequently Asked Questions

Which backend frameworks does this skill support?
The guidance is framework-neutral, with FastAPI examples that can be adapted to Node.js, Java, Go, and other stacks.
Can it design a database schema?
Yes. It can propose models, relationships, indexes, migrations, transaction boundaries, and pagination after receiving domain requirements.
Can it troubleshoot production performance?
Yes. It can structure diagnosis using traces, logs, query plans, pool metrics, profiling, caching, and controlled load tests.
Does it execute deployment commands automatically?
No. The skill provides command references, but execution depends on the active agent, permissions, and explicit user approval.
Does it replace a security review?
No. It supplies security checks, but sensitive systems still require threat modeling, dependency scanning, testing, and qualified review.
What context produces the best result?
Provide the business workflow, stack, schema, traffic, latency goals, infrastructure, security constraints, logs, and relevant code.
