Chasing Mastery Author plugin
One source-owned plugin for Codex, ChatGPT, and Claude—portable packages, Station connectors, and scoped Club setup from a blank workspace.
Chasing Mastery Author is one plugin with three focused skills:
| Skill | Use it for |
|---|---|
| Build a Chasing Mastery package | Experience Suites, Practice Modes, rich players, progression, Story Events, overlays, coordination, and narration |
| Build a Chasing Mastery connector | Native/local source discovery and semantic observations through Station |
| Manage Chasing Mastery Club | Pursuit discovery, Suite install, Practice Mode setup, Sprints, and owner-private package submission through scoped OAuth |
You describe the product outcome. The skill asks only the missing questions, writes a durable authoring brief, bootstraps a standalone workspace, and drives the project-local tools. Package and connector authoring remain separate trust lanes even though they ship in one plugin.
Blank-machine behavior
The package skill does not require a platform checkout or global CLI. Its
bootstrap uses exact Node 24.18.0 or installs that checksum-pinned portable
runtime in an author cache, verifies bundled toolchain digests, and creates the
project. It never uses sudo, a system package manager, or a global npm install.
Connector authoring needs Rust 1.95 because it produces a supervised sidecar.
The skill keeps the connector's Rust SDK, Lab, and sandbox project-local. The
public archive carries reviewed Lab/sandbox binaries for Linux x86-64 and Apple
Silicon macOS; Windows and Intel macOS are not certified connector-authoring
hosts.
Exact release source
The canonical plugin snapshot is plugins/chasing-mastery-author. Its
.codex-plugin/plugin.json describes the single plugin, release.json pins the
payload digest and file count, and each skill contains its own references,
fixtures, scripts, and toolchain assets. The docs build verifies those files and
the release record rather than copying a second authoring specification.
Developer Preview 0.2.0 is publicly downloadable with exact release metadata. Claude Code has a checksum-pinned HTTPS marketplace, Codex has a verified local marketplace bundle, and eligible ChatGPT plans can upload either focused local authoring skill. The OpenAI universal-directory listing is submission-ready but truthfully remains unavailable until the production MCP resource and external review are complete. Follow Build with your agent for the current supported path instead of guessing an install command.
What the plugin will never request
- a Chasing Mastery password or browser session;
- an API, store, publisher, Station, or provider secret in a prompt;
- direct database or account storage access;
- arbitrary filesystem/network/native authority for a portable package;
- permission to publish merely because local conformance passed.
Club setup uses first-party OAuth consent with separate club.read,
club.manage, and packages.submit scopes. Package authoring itself remains
local until the member explicitly asks to submit exact review bytes.
