Orchestrate iterative development from large or ambiguous specs: extract requirements with proof obligations and behavior scenarios, scope walking skeleton roadmap, then loop audited sprints via TDD tasks, code reviews, and evidence accumulation until auditor confirms spec match.
npx claudepluginhub prime-radiant-inc/prime-radiant-marketplace --plugin iterative-developmentUse when an iteration has just finished and you need to verify behavior evidence quality in three tiers — deep evidence for current stories, impacted behavior for touched scenarios, and sentinel corpus for high-value regression detection.
Use when starting an iterative-development run on human spec collateral — reads the spec, produces per-epic requirement files with proof obligations and behavior scenario cards with stable IDs.
Use when executing a batch of TDD-sized tasks inside a running-an-iteration call — dispatches an implementer subagent per task following red-green-refactor discipline and returns per-task completion status.
Use when implementing a project with a large, comprehensive, or ambiguous spec — extracts requirements with proof obligations, defines a walking skeleton with its first journey scenario, then loops through audited sprints that continuously build a behavior evidence corpus. Completion means passing evidence, not just finished stories.
Use when executing the next pending iteration from an iterative-development roadmap — picks the iteration, decomposes into code and evidence tasks, runs sentinel corpus baseline, dispatches implementing-tasks, runs impacted + sentinel scenarios, and updates artifacts.
Use when turning extracted requirements into a roadmap — selects the walking skeleton iteration with its first journey scenario, orders remaining work into follow-on iterations, and applies story splitting when ACs have different dependency profiles.
A Claude Code plugin that drives an autonomous, audited implementation loop for projects with large, comprehensive, or ambiguous specs. Pairs with superpowers.
Use this plugin when:
superpowers:writing-plans → superpowers:subagent-driven-development flow has lost the plot on this project before.Do not use it for small, bounded projects — superpowers:writing-plans is simpler and more appropriate.
The top-level iterative-development skill orchestrates the full lifecycle:
Completion means the product has passing behavior evidence at the correct seam for every externally observable requirement — not just that stories are marked done.
| Skill | Role |
|---|---|
iterative-development | Top-level orchestrator for the autonomous loop. |
extracting-requirements | Chunk + parallel-extract + aggregate stories and scenarios from spec collateral. |
scoping-the-simplest-core | Define walking skeleton and roadmap. |
running-an-iteration | Execute one sprint end-to-end. |
implementing-tasks | Per-task implementer with evidence discipline. |
auditing-progress | PAR-based audits at iteration and corpus level. |
Install from the Prime Radiant marketplace:
/plugin marketplace add prime-radiant-inc/prime-radiant-marketplace
/plugin install iterative-development@prime-radiant-marketplace
Restart Claude Code after installing.
./scripts/run_validation_suite.sh
Individual test files can be run with pytest tests/.
This plugin depends conceptually on skills from the superpowers plugin (brainstorming, TDD, parallel adversarial review, verification-before-completion). Install superpowers alongside iterative-development for the intended experience.
