Flowspec Marketplace
Run spec-driven development end-to-end in Claude Code with slash commands, specialist agents, and pre-wired MCP for security and shipping.
Overview
flowspec is a plugin marketplace for the Build phase that delivers a spec-driven SDLC toolkit with six slash commands, fifteen agents, and nine integrated MCP servers for Claude Code.
What is this marketplace?
- 6 workflow slash commands: specify, plan, research, implement, validate, operate
- 15 specialized agents for SDLC coverage across many languages
- 9 pre-configured MCP servers (GitHub, Serena, Context7, Playwright, Trivy, Semgrep, Figma, shadcn-ui, Chrome DevTools)
- Multi-language support from C/C++ through TypeScript and Dart/Flutter
- Integrated DevSecOps, observability, Kubernetes, and SRE-oriented practices
- 1 plugin (flowspec v0.0.20, MIT)
- 6 slash commands, 15 agents, 9 pre-configured MCP servers
Community signal: 45 GitHub stars.
What problem does it solve?
Builders juggling specs, agents, security scans, and ops tooling waste time wiring Claude Code instead of shipping validated software.
Who is it for?
Technical solo builders or tiny teams using Claude Code 2+ who want SDD, CI/CD-minded validation, and security MCP in one marketplace.
Skip if: Casual snippet helpers, non-Claude agents without marketplace support, or projects that only need a single-purpose skill with no SDLC ritual.
What do I get? / Deliverables
After registering the marketplace, you get a structured specify→operate command set with agents and MCP ready for multi-language, DevSecOps-aware delivery.
- Specs, plans, and research artifacts from workflow commands
- Implemented changes guided by implement/validate steps
- Operational and security validation hooks via bundled MCP
Plugins in this marketplace

Recommended Marketplaces
Journey fit
A full SDLC toolkit anchors in build because implementation, agents, and integrated tooling are its center of gravity, even though it touches earlier spec work and later ops. PM subphase fits orchestration workflows—specify, plan, research, implement, validate, operate—as repeatable project methodology rather than a single integration task.
How it compares
Full SDLC plugin marketplace with agents and MCP, not a single frontend skill or a lone integration server.
Common Questions / FAQ
Who is flowspec for?
Developers and indie teams on Claude Code who want spec-driven workflows, specialist agents, and integrated GitHub, testing, and security MCP across many languages.
When should I use flowspec?
Use it when starting or running a feature from specification through implementation, validation, and operational follow-up—not for one-off edits without a plan.
How do I add flowspec to my agent?
Install the jpoley/flowspec Claude marketplace, ensure Node 18+, Python 3.11+, and Claude Code 2.0+, then use slash commands like /specify and /implement in your project.
