# Meshy 3D Generation
Use Meshy CLI **0.8** (0.8.5 or later) to turn the user's request into a delivered asset. Completion means
saving the requested files in the requested location and inspecting an available preview.
Login or task submission alone is not completion. Choose the shortest suitable pipeline and
reuse existing assets for follow-ups.
## Read what this request needs
| Need | Reference |
|---|---|
| CLI runner, credentials, or output location | [Setup](references/setup.md) |
| Generation and the models to pair for a project, texturing, remeshing, conversion, scale, or 2D images | [Pipelines](references/pipelines.md) |
| Rigging, animation, or generated motion | [Animation](references/animation.md) |
| Cost, waiting, preview, delivery, or finding a previous model | [Delivery](references/delivery.md) |
| Failed or uncertain operation | [Troubleshooting](references/troubleshooting.md) |
Read the relevant section when needed; recipes are examples to adapt to the requested result,
not a requirement to execute every stage. An untextured model skips texture generation; an
existing GLB needs no extra format conversion. Use command help when parameters are uncertain.
## First use and authorization
In DeepSeek Harness with the Meshy plugin (`DSH_MESHY_CLI` is set) run every command as
`"$DSH_MESHY_NODE" "$DSH_MESHY_CLI" …`, never a `meshy` on PATH, install nothing, and sign in with
the `meshy_sign_in` tool. Everywhere else run `meshy --version` before the first command, without
asking; when it is missing or older than 0.8.5, install it with `npm install -g meshy-cli@0.8`
and say so in one line ([Setup](references/setup.md), section 1).
Reuse a verified session. If login is needed, run `auth login --device` (with `--region cn` for a
user in mainland China) as Setup, section 3 describes: show its URL and user code in
**commentary/progress, not a final answer**, wait on that same command in this turn, verify
`auth status`, then continue the original request. Browser approval stays with the user;
credentials never belong in chat, and only the CLI touches its config directory.
## Execution boundaries
- Run API, upload, download and mesh operations through the CLI. Local inputs have a 50 MiB
limit, and a local model must be GLB or glTF (rigging, UV unwrap and multicolor: GLB); use the supported
URL input route for anything else.
- Use `--format json --no-update-check` on every command: stdout is one `meshy.cli/v1` envelope,
auth included. Resolve `WORKSPACE` from the user's output
path and pass it to writes.
- Know what the model is for before the first paid create: a game asset, a character to rig, a
render, a 3D print. If the user hasn't said, ask once; the answer picks the route and the models
([Pipelines](references/pipelines.md)). A game asset or a face-count budget means smart topology,
not a standard model remeshed down.
- Submit once with `create --async`, retain the owning resource and ID, then `wait` on that
task. Keep the agent turn active while awaiting a running command. Follow Troubleshooting
on timeout or unknown submission; these do not authorize another paid create.
- Without a usable photo, recommend making a reference image first and building the model
from it; text-to-3d is the quicker alternative ([Pipelines](references/pipelines.md), *Start
from an image*).

# Meshy 3D Printing
Use Meshy CLI **0.8** (0.8.5 or later) to deliver the requested print files at the intended size, with
analysis/repair results where applicable and a slicer handoff when requested. This skill is
self-contained. Ordinary digital assets belong to meshy-3d-generation.
| Need | Reference |
|---|---|
| CLI runner, credentials, or output location | [Setup](references/setup.md) |
| Local preparation, white or multicolor prints, analysis/repair, or splitting into parts | [Printing recipes](references/printing.md) |
| Creative Lab products (figures, lamps, keychains, magnets, keycaps, fidgets) | [Creative Lab](references/creative-lab.md) |
| Cost, waiting, preview, delivery, or finding a previous model | [Delivery](references/delivery.md) |
| Failed or uncertain operation | [Troubleshooting](references/troubleshooting.md) |
Read relevant sections as needed. Recipes illustrate valid commands; select only the stages
needed for the user's output.
## Choose local or cloud work
| Request | Route |
|---|---|
| Scale, orient or ground an existing OBJ | Local `mesh prepare-print`; no auth or balance |
| Open an existing STL or 3MF | Local `slicer detect` and `slicer open`; no auth or balance |
| White model from a photo, a sketch or text | Photo: image-to-3d. Otherwise recommend a reference image first (multi-view when depth or sides matter), with text-to-3d as the quicker alternative; geometry without textures; analyze/repair as needed; prepare the file |
| Multicolor model | Generate/reuse geometry; analyze/repair as needed; texture; multi-color-print |
| Print in separate parts (build plate, colours per part, fewer supports) | Generate/reuse geometry; auto-split; slice the parts |
| Check or fix an existing model (holes, thin walls), any format | Free analyze-printability by task ID or `--model-url`; repair only if needed |
| Resize an existing STL, 3MF or GLB | Scale it in the slicer; only an OBJ is resized locally |
| Creative Lab figure (a stylized collectible from a photo), vinyl figure, brick figure, lamp, keychain, fridge magnet, keycap or pixel fidget board | Prototype → review → build → select product artifacts |
| Creative Lab collapsible fidget | One create from the photo → STL |
Colour routes differ: multicolor paints one object's surface for a multi-material printer; a
split cuts it into parts, one filament each, and drops the texture (split before any repair;
the two do not chain); the pixel fidget board is a product of its own.
A figurine does not by itself require Creative Lab. Infer the route from the intended product;
ask about size, color or style only when the missing choice materially changes the result.
For an existing model, distinguish local preparation from cloud printability analysis; a
local dimension check cannot establish full printability.
## Cloud authorization
In DeepSeek Harness with the Meshy plugin (`DSH_MESHY_CLI` is set) run every command as
`"$DSH_MESHY_NODE" "$DSH_MESHY_CLI" …`, never a `meshy` on PATH, install nothing, and sign in with
the `meshy_sign_in` tool. Everywhere else run `meshy --version` before the first command, without
asking; when it is missing or older than 0.8.5, install it with `npm install -g meshy-cli@0.8`
and say so in one line ([Setup](references/setup.md), section 1). Local-only work stops there.
Cloud work reuses a verified session. If login is needed, run `auth login
