Build, customize, audit, and package native macOS desktop-pet apps from owned or licensed image/video assets. Use when Codex needs to create an AppKit transparent floating pet, convert transparent/green-screen/black-screen animation clips into PNG frame packs, replace pet actions, prepare a universal macOS app, separate a public open-source engine from restricted demo assets, or inspect a desktop-pet repository before public release.

Build macOS Desktop Pet
Create rights-safe native macOS desktop pets from the bundled public template. Keep private or restricted character demos outside public repositories.
Workflow
- Inspect the workspace before copying files.
- Locate existing source, asset manifests, animation sources, build scripts, licenses, credentials, local paths, and generated artifacts.
- Identify who owns each visual, audio, name, logo, costume, and reference image.
- Treat a recognizable real person, brand, team, or protected character as third-party material even when the drawing or animation itself is original.
- Choose the distribution lane.
- Public/open source: include only generic code and owned or redistributable demo assets.
- Restricted demo: isolate it in a separate private directory/repository and follow references/restricted-demo.md.
- Never present a disclaimer, noncommercial label, or "do not redistribute" notice as a substitute for consent or a license.
- Start a clean public project.
- Run
scripts/create_from_template.py --target <path> --app-name <name> --bundle-id <id>. - Do not initialize a public repository from a private character workspace with sensitive history.
- Keep the bundled Blob frames until the user's replacement assets pass validation.
- Prepare animation assets.
- Read references/asset-pipeline.md.
- Copy
assets_config.example.jsontoassets_config.jsonin the output project. - Use absolute source paths only in the ignored local config.
- Run the template's
scripts/preprocess_assets.pyfor owned/authorized clips. - Inspect representative first, middle, and final frames for edge halos, clipping, scale drift, anatomy changes, and background leakage.
- Adapt behavior and identity.
- Update
PetAction.swiftwhen adding or removing actions. - Keep
AssetCatalog.validateRequiredAssets()synchronized with the shipped actions. - Replace the display name, bundle ID, About text, menu labels, icon, and asset provenance.
- Preserve transparent hit testing and click-through behavior unless the user explicitly requests another interaction model.
- When adding system cursor themes, read references/cursor-themes.md.
- Keep cursor artwork in the same owned/licensed asset lane as character art. Never copy restricted demo
.capefiles into the public template. - Treat Mousecape as an optional, separately installed dependency. Do not bundle it or imply that this project's Apache-2.0 license overrides its upstream terms.
- Build and verify.
- Run
scripts/check_demo.shin the output project. - Run the built executable with
--cursor-self-testwhen cursor themes are configured. - Require x86_64 and arm64 for a general macOS release unless the user explicitly limits architectures.
- Check idle CPU, memory growth across every action, multi-display placement, Spaces/full-screen behavior, sleep/wake, and first-run installation.
- Audit before publication.
- Run
scripts/audit_public_release.py <path>and add--deny-term <term>for every private person, brand, project name, or internal codename that must not appear. - Read references/release-checklist.md.
- Do not publish when the audit finds credentials, signed URLs, authentication QR codes, local paths, restricted assets, or unclear licensing.
- Package only within the user's requested scope.
- Local builds may use ad-hoc signing.
- Public binary releases should use the user's Developer ID and Apple notarization credentials; do not request or expose private keys.
- Do not upload, publish, or create a public repository unless the user explicitly asks for that external action.
