Is the Iterative Development skill free?

Yes. The skill itself is free from prime-radiant-inc/iterative-development. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Iterative Development SkillProof Score?

8.8/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 4/5.

How do I install Iterative Development?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Iterative Development with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

This orchestrator is the front door to a 6-skill plugin bundle — copying only its own SKILL.md leaves it calling extracting-requirements, scoping-the-simplest-core, and four other named skills that must ship alongside it. On a toy spec it correctly forced a testable 'proof obligation' per story and refused to let scope grow past a single working end-to-end journey, a discipline a freeform task list skipped entirely.

What Iterative Development does

Orchestrates a multi-day autonomous build loop for large or ambiguous specs: extracts requirements as story cards with proof obligations and behavior scenarios, defines a walking skeleton that must close a real end-to-end journey before expanding, then runs audited sprints backed by a growing behavior-evidence corpus. Trigger it on '10+ file spec', 'ambiguous requirements', or 'continue iterative development with the existing plan'; skip it for small bounded tasks, which it explicitly defers to a simpler upfront-planning flow.

How to install Iterative Development

git clone https://github.com/prime-radiant-inc/iterative-development
cd iterative-development
mkdir -p ~/.claude/skills
cp -r skills/iterative-development ~/.claude/skills/iterative-development

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Iterative Development

/iterative-development Audited sprint loop for large ambiguous specs — proof obligations over checked boxes.

It also activates on plain-language prompts like these:

This spec has 10+ files and ambiguous requirements, run it as sprints
Break this big vague spec into story cards with proof obligations
Continue the iterative development loop using the existing plan
