Sim Sim assets for AI agents
Start with https://simsim.deovia.com/assets.json. Every record includes an agent object linking to its per-asset manifest, editing guide, instructions and complete ZIP kit. These are public, static HTTPS downloads; no account, API key or JavaScript rendering is needed. Private editor notes are excluded.
Understand → download → revise
- GET /assets.json and select the stable asset ID. Read agent.manifest, then the manifest's guide and instructions.
- Download agent.bundle and compare SHA-256 with agent.bundle_sha256 before extracting. Extract into a new directory. Every kit includes asset.json, EDITING.md, AGENTS.md, source/reference files and the offline asset.py tool.
- Inspect the helper, then run python3 asset.py verify. Each file's relative path, public download URL, media type, byte size and SHA-256 are in asset.json.
- Follow EDITING.md. Hearth can rebuild geometry from editable JSON. Listener and First Light expose editable PNGs; use an image editor or an authorized image-generation tool. Missing layered or 3D sources are stated explicitly.
- Run the kit's revision command to record the base fingerprint, change summary, tool provenance and output hashes. Return the candidate directory to the studio editor.

Publishing contract
Downloading and creating a local candidate do not alter the archive. There is no public asset-write or upload endpoint. An authorized studio publishing agent checks the candidate against the current source fingerprint, reviews its actual files, and adds a new version through the existing source repository and Sites publishing workflow. Preserve old version URLs. A changed source returns to review; a website publication is not approval for inclusion in the game.
Asset IDs remain stable, including the existing first-light-concept-v01 identifier. Versions and kit revisions are separate: an improved helper need not pretend that the artwork changed. Checksums establish file identity, not quality, safety or legal rights. Current assets are early candidates; engine import and player validation remain unrun.
The helper performs no downloads, model calls or publication. No image-generation API is configured. Never expose editor cookies, secrets or private notes in an asset kit. The public site does not supply an agent identity or grant publishing permissions.
