Practical overview
When it fits
Use it when a specification is complex enough to require staged implementation and evidence-based audits, particularly when a single upfront planning flow has become difficult to control.
Who it is for
- Teams handling large, comprehensive, or ambiguous software specifications
- Claude Code users who need requirements and behavior evidence tracked through implementation
- Developers seeking a walking-skeleton roadmap and repeated progress audits
Documented uses
- Extract structured stories, proof obligations, and behavior scenarios from specification material
- Prioritize a simplest working product core and sequence follow-on iterations
- Coordinate implementation tasks with evidence tasks
- Audit progress against impacted and sentinel behavior scenarios
Requirements & limits
The repository is public and open source under the Apache-2.0 license. Installation is documented through the Prime Radiant marketplace in Claude Code. No pricing or account requirement is documented.
- It is a Claude Code plugin, not a standalone hosted workflow service.
- Its workflow covers extraction, walking-skeleton scoping, implementation, auditing, and termination.
- The completion criterion emphasizes passing behavior evidence at the correct seam, not only completed task status.
- The documented companion workflow uses the separate superpowers plugin.
- The repository explicitly positions a simpler planning approach as more appropriate for small, bounded projects.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Install Iterative Development with its intended Claude Code companion
Set up the plugin from the Prime Radiant marketplace and pair it conceptually with superpowers.
Before you start
- Claude Code
- The Prime Radiant marketplace
- The superpowers plugin for the intended companion workflow
Steps
Add the Prime Radiant marketplace with
/plugin marketplace add prime-radiant-inc/prime-radiant-marketplace.Install the plugin with
/plugin install iterative-development@prime-radiant-marketplace.Restart Claude Code after installation.
Install superpowers alongside Iterative Development for the documented brainstorming, TDD, parallel-review, and verification workflow.
Expected outcome
Iterative Development is installed in Claude Code with the companion relationship described by the repository.
Guide limitations
- The supplied documentation does not provide a test result for the combined setup.
- The superpowers relationship is described as conceptual dependency rather than a demonstrated integration test.
