Devbrother Plugins

Add DevBrother plugins when you want a cross-model verification skill that compares Codex, Gemini, and Claude answers before you trust a single agent response.

Overview

DevBrother Plugins is a plugin marketplace for the Validate phase that ships cross-verify, a skill to compare Codex, Gemini, and Claude responses before you commit to technical decisions.

What is this marketplace?

  • cross-verify skill compares answers from Codex (GPT), Gemini, and Claude in one workflow.
  • DevBrother-maintained Claude Code plugin marketplace with simple /plugin install cross-verify@devbrother-plugins path.
  • Useful sanity check when one model hallucinates APIs, limits, or library behavior.
  • Lightweight add-on for builders already running multiple model subscriptions.
  • Focused catalog: one documented plugin today with room to grow under the same marketplace.
  • Marketplace metadata lists 1 plugin
  • Documented flagship plugin: cross-verify

Compatible agents: Claude Code

Community signal: 8 GitHub stars.

What problem does it solve?

A single LLM can sound confident while being wrong about APIs, versions, or edge cases, and solo builders lack a fast way to triangulate answers inside Claude Code.

Who is it for?

Solo builders using Claude Code who already use or can access GPT/Codex and Gemini and want verification baked into the plugin workflow.

Skip if: Builders who only use one model with no cross-access, or teams needing deep automated test or MR review tooling instead of answer comparison.

What do I get? / Deliverables

After installing cross-verify from this marketplace, you can run structured cross-model comparisons and spot conflicts before scope or code changes harden.

  • cross-verify@devbrother-plugins skill available in Claude Code
  • Repeatable cross-model comparison workflow for technical questions
  • Clearer confidence before scope or implementation commits

Journey fit

Primary fit

Builders reach for cross-verification earliest while scoping and validating decisions, before expensive implementation commits. scope fits because the flagship cross-verify skill is about reconciling conflicting AI guidance while defining what to build and how.

How it compares

Multi-model answer verification skill, not a Git hosting MCP server or an autonomous development loop marketplace.
