Pl4n

gbasin/pl4n·1 plugin

Overview

pl4n is a plugin marketplace for the validate phase that registers a multi-agent CLI to co-author implementation plans with Claude Code, Codex, and human review.

What is this marketplace?

Bundles one pl4n plugin that orchestrates Claude Code and Codex for collaborative planning
Human-in-the-loop review gates between multi-agent plan drafts
Bun + TypeScript ensemble CLI aimed at implementation-plan workflows
Keywords cover multi-agent orchestration, Codex, and Claude Code
MIT-licensed plugin v0.2.0 from the gbasin/pl4n repository

Compatible agents: Claude Code, Codex, any compatible agent

What problem does it solve?

Splitting planning across Claude Code and Codex without a shared workflow leaves contradictory specs and skipped review.

Who is it for?

Indie builders who routinely pair Claude Code with Codex and want ensemble planning with explicit human gates.

Skip if: Builders who only need a one-off prompt or a single-agent skill with no orchestration CLI.

What do I get? / Deliverables

After adding the marketplace you get orchestrated, reviewable implementation plans both agents helped shape.

Journey fit

Primary fit

Canonical shelf is validate because the marketplace centers on producing reviewed implementation plans before heavy build work. Scope subphase fits structured planning and ensemble review rather than a single integration hook.

How it compares

Multi-agent planning marketplace, not a single-task MCP server or UI component pack.
