issue-driven-development

A Claude Code plugin marketplace for the Issue-Driven Development (IDD) methodology.

TDD writes tests. SDD writes specs. IDD solves bugs.

Plugins

Plugin	Version	Purpose
issue-driven-dev	2.37.0	Core IDD workflow — issue → diagnose → implement → verify → close. 13 skills + 5 rules + 5 references.
idd-route (coming)	0.1.0	Data-driven agent routing: recommends Codex / Claude Opus / Sonnet / Haiku per IDD issue based on observed track record. Wraps the PsychQuant/idd-route-swift binary.

Installation

claude plugin marketplace add PsychQuant/issue-driven-development
claude plugin install issue-driven-dev@issue-driven-development

Why a separate marketplace?

IDD is a methodology unto itself with its own MANIFESTO and steady release cadence (38+ versions). Pulling it out of psychquant-claude-plugins (which has ~36 unrelated plugins) gives:

• Cleaner discoverability for users adopting IDD without the rest of the PsychQuant ecosystem
• Independent release cycle
• Room to grow related sister plugins (idd-route, future idd-bench / idd-stats / idd-codex-companion)

Migration from psychquant-claude-plugins

If you previously installed issue-driven-dev from psychquant-claude-plugins, you need to switch source:

claude plugin uninstall issue-driven-dev@psychquant-claude-plugins
claude plugin marketplace add PsychQuant/issue-driven-development
claude plugin install issue-driven-dev@issue-driven-development

Settings (.claude/issue-driven-dev.local.json, .claude/.idd/) and per-repo state are preserved — they live in your project repos, not in the plugin install.

Workflow

issue → diagnose → implement → verify → close
  ①        ②           ③         ④       ⑤

Each step is one skill. See the plugin README for details.
