Codex Next

Codex Next

Codex Next is an installable Codex plugin that packages the public-safe skills from this repository into one reusable workflow bundle.

It is meant to strengthen Codex with repeatable software delivery workflows: task routing, project research, requirements, architecture, specs, validation, handoff, implementation support, review, data work, office writing, and research synthesis.

What It Includes

• A plugin entrypoint skill, core-router, for routing work to the smallest useful bundled workflow.
• SDLC and delivery skills such as sdlc-manager, sdlc-router, sdlc-requirements-workflow, sdlc-solution-spec-workflow, sdlc-dev-handoff-planning, and sdlc-readiness-review.
• Development skills such as dev-repo-onboarding, dev-bugfix, dev-spec-driven-implementation, dev-pr-review, dev-security-review, dev-test-strategy, and dev-release-check.
• Data, office, research, and common workflow skills from the public catalog.

What It Does Not Include

• Custom agent TOML files from .codex/agents.
• V1 machine-local suite symlinks or runtime .codex entrypoints.
• Private prompts, private paths, credentials, or unpublished skills.

Custom agents remain a separate Codex subagent configuration layer. This plugin ships reusable skills.

Package Layout

This directory is the plugin package:

plugins/codex-next/
  .codex-plugin/plugin.json
  README.md
  skills/
    <skill-name>/
      SKILL.md
      references/
      scripts/
      assets/

Only .codex-plugin/plugin.json belongs inside .codex-plugin/. Bundled components such as skills/, future .mcp.json, future .app.json, and future assets/ belong at the plugin root and are referenced from the manifest with paths relative to this directory.

The repo marketplace is outside this package:

.agents/plugins/marketplace.json

The marketplace exposes the checked-in plugin to Codex. It is a catalog entry, not part of the plugin package itself.

Install

For a network install from GitHub, add the marketplace source:

codex plugin marketplace add https://github.com/BlueSkyXN/Codex-is-all-you-need.git

For local development, add the checked-out repository root instead:

codex plugin marketplace add /path/to/Codex-is-all-you-need

Check that Codex can see the uninstalled marketplace entry. The --available flag is required when using JSON output; without it, codex plugin list --json only shows installed plugins.

codex plugin marketplace list --json
codex plugin list --marketplace codex-is-all-you-need --available --json

Then install the plugin from the configured marketplace:

codex plugin add codex-next@codex-is-all-you-need

After installation, start with:

$codex-next:core-router

or ask Codex to use Codex Next for the task.

If you are migrating an existing V1 machine from suite-based runtime entrypoints, see V1 To V2 Migration.

Local Development

Validate the plugin manifest with:

python3 ~/.codex/skills/.system/plugin-creator/scripts/validate_plugin.py \
