PowerSync Skills

Use this skill to onboard a project onto PowerSync without trial-and-error. Treat this as a guided workflow first and a reference library second.

Agents: Follow AGENTS.md in full — including Agent compliance (ask Cloud vs self-hosted, ask backend if unspecified, CLI-first, no silent shortcuts). powersync login is PowerSync Cloud only (PAT); self-hosted does not use it.

Quick Rules

CLI-first. Use the PowerSync CLI for all operations. Do not hand-write config files. See references/powersync-cli.md.
Ask, don't assume. Ask Cloud vs self-hosted. Ask which backend (Supabase, Postgres, MongoDB, MySQL, MSSQL). Do not default to Supabase.
Backend before frontend. Deploy sync config and verify the service before writing app code.
Sync Streams for new projects. Sync Rules are legacy.
Persist credentials immediately. Write all URLs and keys to .env as soon as they are available.

What to Load for Your Task

Task	Start with	Load on demand
Supabase + PowerSync	`references/onboarding-supabase.md`	`references/supabase-auth.md`, `references/sync-config.md`, SDK files
Custom backend (non-Supabase)	`references/onboarding-custom.md`	`references/custom-backend.md`, `references/sync-config.md`, SDK files
New project setup	`references/powersync-cli.md` + `references/powersync-service.md`	`references/sync-config.md`, SDK files
Self-hosting / service config	`references/powersync-service.md` + `references/powersync-cli.md`	`references/sync-config.md`
Writing sync config	`references/sync-config.md`	—
Debugging sync issues	`references/powersync-debug.md`	—
Attachments	`references/attachments.md`	—
Architecture overview	`references/powersync-overview.md`	—

SDK Reference Files

JavaScript / TypeScript

Always load references/sdks/powersync-js.md for any JS/TS project, then load the applicable framework file.

Framework	File	Load early if…
React / Next.js	`references/sdks/powersync-js-react.md`	Vite + React project — contains the required `vite.config.ts` setup (`optimizeDeps.exclude`, `worker.format: 'es'`) needed before installing packages
React Native / Expo	`references/sdks/powersync-js-react-native.md`
Vue / Nuxt	`references/sdks/powersync-js-vue.md`
Node.js / Electron	`references/sdks/powersync-js-node.md`
TanStack	`references/sdks/powersync-js-tanstack.md`

Other SDKs

Platform	File
Dart / Flutter	`references/sdks/powersync-dart.md`
.NET	`references/sdks/powersync-dotnet.md`
Kotlin	`references/sdks/powersync-kotlin.md`
Swift	`references/sdks/powersync-swift.md`

Key Rules to Apply Without Being Asked

Never define the id column in a PowerSync table schema; it is created automatically.
Use column.integer for booleans and column.text for ISO date strings.
connect() is fire-and-forget. Use waitForFirstSync() if you need readiness.
transaction.complete() is mandatory or the upload queue stalls permanently.
disconnectAndClear() is required on logout or user switch when local data must be wiped.
A 4xx response from uploadData blocks the upload queue permanently; return 2xx for validation errors.

how to use powersync

How to use powersync on Cursor

AI-first code editor with Composer

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

›Cursor installed and configured on your development machine
›Node.js version 16.0+ with npm package manager (verify with node --version)
›Active project directory or workspace where you want to add powersync

Execute installation command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/powersync-ja/agent-skills --skill powersync

The skills CLI fetches powersync from GitHub repository powersync-ja/agent-skills and configures it for Cursor.

Select Cursor when prompted

The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:

◆ Which agents do you want to install to?

│

│ ── Universal (.agents/skills) ── always included ────

│ • Amp

│ • Antigravity

│ • Cline

│ • Codex

│ ●Cursor(selected)

│ • Cursor

│ • Windsurf

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/powersync

Reload or restart Cursor to activate powersync. Access the skill through slash commands (e.g., /powersync) or your agent's skill management interface.

⚠

Security & Verification Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.

Use Cases▌

User Story & Requirements Generation

Create detailed user stories, acceptance criteria, and feature specs

Example

Generate user stories for 'password reset feature' with acceptance criteria, edge cases, and test scenarios

✓

Reduce spec writing time by 50%, ensure comprehensive coverage

Competitive Analysis

Research competitors, compare features, identify gaps

Example

Analyze 5 competitor products, create feature comparison matrix, suggest differentiation opportunities

✓

Complete competitive research in 2 hours instead of 2 days

Roadmap Prioritization

Evaluate features using frameworks (RICE, ICE, Kano) and create prioritized backlogs

Example

Score 20 feature ideas using RICE framework, generate prioritized roadmap with rationale

✓

Make data-driven prioritization decisions faster

Stakeholder Communication

Draft PRDs, status updates, and stakeholder presentations

Example

Create executive summary of Q3 roadmap, monthly progress report, feature launch announcement

✓

Save 3-5 hours/week on communication overhead

Implementation Guide▌

Prerequisites

›Claude Desktop or compatible AI client
›Access to product documentation and roadmap tools (Jira, Notion, etc.)
›Understanding of product management frameworks (RICE, Jobs-to-be-Done, etc.)
›Stakeholder contact information and communication channels

Time Estimate

30-60 minutes to see productivity improvements

Installation Steps

1.Install product management skill
2.Start with user story generation for known feature
3.Progress to competitive analysis: research 2-3 competitors
4.Use for roadmap prioritization: apply RICE/ICE scoring
5.Draft stakeholder communications and refine based on feedback
6.Build template library for recurring PM tasks
7.Share effective prompts with product team

Common Pitfalls

⚠Not validating competitive research—verify facts before sharing
⚠Accepting user stories without involving engineering team
⚠Over-relying on frameworks without qualitative judgment
⚠Not customizing outputs to company culture and communication style
⚠Skipping stakeholder validation of generated requirements

Best Practices▌

✓ Do

+Validate research and competitive analysis with real data
+Collaborate with engineering when generating technical requirements
+Customize frameworks and templates to your company context
+Use skill for first drafts, refine with stakeholder input
+Document successful prompt patterns for PM tasks
+Combine AI efficiency with human judgment and intuition

✗ Don't

−Don't publish competitive analysis without fact-checking
−Don't finalize user stories without engineering review
−Don't make prioritization decisions solely on AI scoring
−Don't skip customer validation of generated requirements
−Don't ignore company-specific context and culture

💡 Pro Tips

★Provide context: company goals, constraints, customer feedback
★Ask for alternatives: 'Show 3 ways to prioritize this roadmap'
★Request stakeholder-specific formatting: 'Executive summary vs. engineering spec'
★Use skill for 70% generation + 30% customization to company needs

When to Use This▌

✓ Use When

Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.

✗ Avoid When

Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.

Learning Path▌

1Basic: user stories, feature specs, status updates
2Intermediate: competitive analysis, prioritization frameworks, PRDs
3Advanced: product strategy, go-to-market planning, OKR setting
4Expert: product vision, market positioning, business model innovation
