# Meshy 3D Generation Directly communicate with the Meshy AI API to generate 3D assets. This skill handles the complete lifecycle: environment setup, API key detection, task creation, polling, downloading, and chaining multi-step pipelines. For full endpoint reference (all parameters, response schemas, error codes), read [reference.md](reference.md). --- ## IMPORTANT: First-Use Session Notice When this skill is first activated in a session, inform the user: > All generated files will be saved to `meshy_output/` in the current working directory. Each project gets its own folder (`{YYYYMMDD_HHmmss}_{prompt}_{id}/`) with model files, textures, thumbnails, and metadata. History is tracked in `meshy_output/history.json`. This only needs to be said **once per session**, at the beginning. ## IMPORTANT: File Organization All downloaded files MUST go into a structured `meshy_output/` directory in the current working directory. **Do NOT scatter files randomly.** - Each project gets its own folder: `meshy_output/{YYYYMMDD_HHmmss}_{prompt_slug}_{task_id_prefix}/` - For chained tasks (preview → refine → rig), reuse the same `project_dir` - Track tasks in `metadata.json` per project, and global `history.json` - Auto-download thumbnails alongside models The Reusable Script Template below includes `get_project_dir()`, `record_task()`, and `save_thumbnail()` helpers. --- ## IMPORTANT: Shell Command Rules **Use only standard POSIX tools in shell commands.** Do NOT use `rg` (ripgr...
