Decide the top-level mode: built-in by default, fallback CLI only if explicitly requested. +2. Decide the intent: `generate` or `edit`. +3. Decide whether the output is preview-only or meant to be consumed by the current project. +4. Decide the execution strategy: single asset vs repeated built-in calls vs CLI `generate-batch`. +5. Collect inputs up front: prompt(s), exact text (verbatim), constraints/avoid list, and any input images. +6. For every input image, label its role explicitly: + - reference image + - edit target + - supporting insert/style/compositing input +7. If the edit target is only on the local filesystem and you are staying on the built-in path, inspect it with `view_image` first so the image is available in conversation context. +8. If the user asked for a photo, illustration, sprite, product image, banner, or other explicitly raster-style asset, use `image_gen` rather than substituting SVG/HTML/CSS placeholders. If the request is for an icon, logo, or UI graphic that should match existing repo-native SVG/vector/code assets, prefer editing those directly instead. +9. Augment the prompt based on specificity: + - If the user's prompt is already specific and detailed, normalize it into a clear spec without adding creative requirements. + - If the user's prompt is generic, add tasteful augmentation only when it materially improves output quality. +10. Use the built-in `image_gen` tool by default. +11. If the user explicitly chooses the CLI fallback, then and only then use the fallback-only docs for quality, `input_fidelity`, masks, output format, output paths, and network setup. +12. Inspect outputs and validate: subject, style, composition, text accuracy, and invariants/avoid items. +13. Iterate with a single targeted change, then re-check. +14. For preview-only work, render the image inline; the underlying file may remain at the default `$CODEX_HOME/generated_images/...` path. +15. For project-bound work, move or copy the selected artifact into the workspace and update any consuming code or references. Never leave a project-referenced asset only at the default `$CODEX_HOME/generated_images/...` path. +16. For batches, persist only the selected finals in the workspace unless the user explicitly asked to keep discarded variants. +17. Always report the final saved path for any workspace-bound asset, plus the final prompt and whether the built-in tool or fallback CLI mode was used. + +## Prompt augmentation + +Reformat user prompts into a structured, production-oriented spec. Make the user's goal clearer and more actionable, but do not blindly add detail. + +Treat this as prompt-shaping guidance, not a closed schema.
