Build Firebase Data Connect Backends
Designing Data Connect schemas and SDK setup can be slow and error-prone. This skill gives focused Firebase guidance for models, operations, authorization, deployment, and client integration.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "firebase-data-connect" from https://skillstore.io/skills/firebase-firebase-data-connect.md and its manifest at https://skillstore.io/api/skills/firebase-firebase-data-connect/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 "firebase-data-connect". Design a movie review backend with public movie browsing and user-owned reviews.
Expected outcome:
A schema plan with movies, actors, users, reviews, relationships, public read queries, authenticated review mutations, and owner filters.
Using "firebase-data-connect". Make sure users can only edit their own notes.
Expected outcome:
An authorization review that recommends user-level access, ownership filters, protected update and delete operations, and validation checks.
Using "firebase-data-connect". Set up SDK generation for web, Android, iOS, and Flutter clients.
Expected outcome:
A connector plan with platform-specific output directories, package names, generation steps, and client initialization notes.
Security Audit
Medium RiskMost static findings are false positives from Markdown, GraphQL, YAML, SDK, and emulator examples. The confirmed risk is operational: Firebase CLI commands can generate files or deploy resources, and Admin SDK examples bypass @auth. No evidence of prompt injection, obfuscation, credential exfiltration, or hidden executable code was found.

These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.

Why this score Evidence Confidence: HighWhat You Can Build
Plan a Data Connect Backend
Design PostgreSQL-backed GraphQL schemas, relationships, indexes, and defaults for a Firebase application.
Secure App Data Access
Add @auth rules, owner filters, role checks, validation, and redaction patterns to Data Connect operations.
Integrate Generated SDKs
Configure connector outputs and call generated operations from Web, Android, iOS, Flutter, or Node services.
Try These Prompts
Create a Firebase Data Connect schema for a task app with users, tasks, due dates, status, and owner-based access.
Write Data Connect queries and mutations for this schema. Include list, detail, create, update, delete, and upsert operations where useful.
Review these Data Connect operations for authorization gaps. Add @auth, auth.uid filters, @check rules, and redaction where needed.
Plan dataconnect.yaml, connector.yaml, SDK generation outputs, emulator workflow, and a deployment checklist for a multi-platform Firebase app.
Best Practices
- Confirm the active Firebase project before running deploy, SDK generation, or emulator commands.
- Use owner filters or role expressions in addition to broad USER authorization for sensitive records.
- Keep generated SDK output paths explicit and review file changes before committing generated code.
Avoid
- Do not use PUBLIC access for user-specific or sensitive data operations.
- Do not rely on Admin SDK operations for client workflows that need user authorization checks.
- Do not deploy generated schemas or operations before reviewing indexes, constraints, and migration impact.
