The +full [Model Fit package](plugins/model-fit/README.md) adds an opt-in profile +handoff for Codex Desktop on macOS. Its runtime code, skill, schemas and local +hook setup live together under `plugins/model-fit/`. + +The repository also builds a separate **guidance-only** package from the same +selection skill. That package recommends a profile and does not switch it or +install hooks. See [the eval suite](evals/model-fit/README.md) for synthetic +cases and the commands that run them. + +The full package is distributed from this repository for manual Desktop +installation. OpenAI's public Plugins Directory currently excludes plugins +containing lifecycle hooks; the guidance-only ZIP is the candidate for that +directory. The ZIPs are separate products with separate behavior and review. +The [verification workflow](.github/workflows/verify.yml) runs on PRs with +Ubuntu, Python 3.9, Ruff's own GitHub Action, deterministic tests and package +assembly. The [release workflow](.github/workflows/release.yml) runs the same +checks when package source reaches `master`, then creates a versioned GitHub +Release with both ZIPs attached. The release's `model-fit-guidance` ZIP is the +input for a separate OpenAI directory upload and review. +Locally, `python3 tools/build.py` writes versioned `dist/model-fit-*.zip` and +`dist/model-fit-guidance-*.zip`. The first copies the full plugin tree; the +second copies the shared skill up to its hook-specific section, then adds its +own manifest, README, icon and license. That transformation is why this +package builder exists: a generic ZIP action can archive a directory but +cannot derive the guidance-only variant from the shared skill. Both manifests +share one release version. Tests inspect the ZIP members, manifest identity, +privacy boundary and byte-for-byte reproducibility. GitHub Release creation +fails if that version already has a release. + +## Distribution and updates + +The installable source under `plugins/model-fit/` is the primary GitHub +distribution. A user adds `atls/codex` as a Codex marketplace, installs the +plugin, and explicitly configures hooks for a selected project and thread. +After a new version is released, they refresh the marketplace and reinstall +the plugin; project-local hook definitions are reviewed and trusted again if +their commands changed. + +There are two separate OpenAI routes: + +- [OpenAI Community Plugins](https://github.com/openai/community-plugins/blob/main/CONTRIBUTING.md) + accepts external contributions through a fork and PR. A contribution needs + the package source under `plugins/model-fit/`, its required Codex manifest, + marketplace entry, cold-start guide, repository-specific master test suite, + CLA and maintainer review. Their repository shape is adapted in the fork; + the ZIP is not pushed there. We do not auto-push to that repository. An + update is a new upstream PR based on a new version of this source. +- The [public Plugins Directory](https://developers.openai.com/plugins/deploy/submission) + accepts a plugin ZIP through the submission portal. Download the separate + `model-fit-guidance` asset from the exact GitHub Release for that route. After publisher + verification, upload the archive, resolve the portal's automated findings, + submit for review, and publish the approved version. An update bumps the + version, uploads a new complete ZIP, and passes the portal checks again. + +The official [`openai/codex-action`](https://github.com/openai/codex-action) +runs Codex in GitHub Actions using an API key; it does not package plugins. +This repository's build script creates the two archives without an API key. +For an update, change the source and bump the version in both manifests, run the +same checks, merge to master to produce a new GitHub Release, refresh the Git +marketplace revision, and then submit separate +upstream Community Plugins PR and Directory ZIP update as applicable. Neither +OpenAI channel is updated merely because this repository's CI passed. + +Neither package includes user conversations, Thread Memory, credentials, +attachments, project hook definitions, or local audit data. + +The source and both package archives use the [BSD 3-Clause License](LICENSE). diff --git a/evals/model-fit/README.md b/evals/model-fit/README.md new file mode 100644 index 0000000..b7db712 --- /dev/null +++ b/evals/model-fit/README.md @@ -0,0 +1,56 @@ +# Model Fit evaluations + +These cases exercise the public Model Fit skill and the hook code without +publishing user conversations.
