newb plugins

The install surface of the flair marketplace (marketplace.useflair.io): one Claude Code plugin and one Codex plugin per published expert agent, plus flair-builder, the plugin experts use to build and publish their own. Both marketplace indexes live at the repo root, so one command adds everything:

/plugin marketplace add newbworks/newb-plugins          # Claude Code
codex plugin marketplace add newbworks/newb-plugins     # Codex

Layout

newb-plugins/
  .claude-plugin/marketplace.json    # Claude Code index
  .agents/plugins/marketplace.json   # Codex index
  builder-claude/                    # flair-builder for Claude Code
  builder-codex/                     # flair-builder for Codex
  <slug>-claude/, <slug>-codex/      # one wrapper pair per published agent
  scripts/sync_marketplace.py        # regenerates the wrappers + indexes

Agent wrappers

Each published agent ships as a thin wrapper whose .mcp.json points at that agent's hosted endpoint (https://agents.useflair.io/mcp/<slug>/). Install one with /plugin install <slug>@newb (Claude Code) or codex plugin add <slug>@newb (Codex). The first call signs you in with your marketplace account (OAuth) and starts you with free credits; the agent itself runs hosted, on the expert's model and tools.

Wrappers carry a .newb-generated marker and are regenerated from the live catalog hourly, on demand, and the moment an agent is published — hand edits are overwritten. See scripts/README.md.

flair-builder — for experts

flair-builder turns a domain expert's process into a hosted agent others can install:

/plugin install flair-builder@newb      # Claude Code
codex plugin add flair-builder@newb     # Codex

Then say "build my agent". It interviews you, scaffolds a bundle, runs it on your own machine, checks it with evals, and publishes it live — self-contained Python scripts under builder-*/scripts/, no CLI or repo needed. The agent then appears here as its own wrapper.

builder-claude/ and builder-codex/ are generated from newbworks/newb (plugins/flair-builder/, rendered from builder/skill/): that repo's sync workflow mirrors the skill and scripts on every push, and python -m newb.marketplace.builder_skill --into <this checkout> writes the manifests, .mcp.json and READMEs. Edit them there.
