Batch Generate Images

Use the local Esse MCP tools. Let Esse resolve the user's configured default offering. Treat agent-generation as cooperation with the current Agent, not as an OAuth or API Provider.

Workflow

1. Treat any request to use esse as permission to show the esse workbench. If the current conversation context does not already include an active Esse MCP App/widget, call open_esse before doing the requested work. Use tab: settings only for setup; otherwise use tab: batches and include a known batchId when available. The widget requests Codex's expanded side view itself. If an active Esse MCP App context is already present, do not open a duplicate.
2. For ordinary generation, omit offeringId. Esse must use the default model configured by the user. Do not call list_image_offerings or compare models just because several are available. Never select a model based on price, subject, capability, or your own preference.
3. Write every image prompt in the language the user is currently using. Chinese requests must produce Chinese image prompts. If the user's language cannot be determined, default to Simplified Chinese. Use English prompts only when the user explicitly requests English.
4. Only when the user explicitly names a different model or asks to inspect/change models, call list_image_offerings and pass an exact matching offeringId. If the requested model is ambiguous, ask the user. If no default is configured, open settings and let the user choose one; never choose the first model automatically. Never ask for an API key in chat.
5. When the request depends on image content, call inspect_image_folder before writing prompts. Page through the folder when needed; do not claim to have inspected unseen images.
6. Treat each batch child as an independent task with its own prompt and zero or more references. Use jobs[] whenever prompts or references differ. For ordinary local files use referenceImagePaths. Use top-level references only when every child intentionally shares them. Do not assume that references apply to the whole batch.
7. When the user says to use an existing Esse result such as 图1 or 图1-1 as a reference, it is a real image attachment requirement, not merely prompt wording. Pass referenceImages: [{ batchId, image: "图1" }] on the affected child job. If the batch ID is not already known from the conversation or tool result, call list_image_batches with a limit from 1 to 50 and resolve the intended batch; if multiple batches are plausible, ask the user. Never invent an output path, never copy only the label into the prompt, and never silently omit the reference. A later user request to reuse a finished result explicitly permits this lookup and is not prohibited polling.
8. For a genuinely new generation request, call create_image_batch once for the approved batch. Never use it to fulfill a request to modify an existing image. Use a stable requestKey so repeated calls do not duplicate work or charges. Tell the user only when local reference files will be sent to the selected external Provider or, for Codex 生成, to the current Agent's image-generation service/model. The docked Esse sidebar discovers and activates the new batch automatically; do not open a duplicate widget.
9. When the user asks to append, add, or generate more images in an existing batch, call append_image_batch_jobs with that exact batchId. This tool can append to active or terminal batches and assigns the next image names in place. Never create a temporary batch or use merge_image_batches to simulate append. Omit offeringId to reuse the batch model; pass it only when the user explicitly names another model. Use a stable requestKey.
10. Inspect the returned offering. For normal Provider offerings, stop after a successful create_image_batch, append_image_batch_jobs, or modify_selected_images; do not poll, monitor, or follow up unless the user asks.
11. When the returned job offering has adapterId: agent-generation, complete it with the current Agent's available image-generation capability. For append requests, act only on the returned appendedJobIds:

• Do not require OAuth, API keys, Codex CLI, or a particular image tool. Use whatever image capability the current Agent already has.
• Choose any safe execution strategy the Agent supports. Subagents are an optional way to parallelize independent jobs, not a requirement. Native batching, other concurrency, or sequential execution are valid.
• If the current Agent cannot generate images, call fail_agent_image_job for every pending job with the real reason and tell the user that the current Agent does not support image generation. Do not leave jobs pending.
• Before generating a job, call start_agent_image_job. Use its exact prompt and every returned referenceImagePaths entry. One start call is exactly one outbound image-generation request: never combine reference paths from other batch jobs into it. Independent jobs may run concurrently, but their prompts, references, and request-size checks stay isolated per job. For a built-in image tool that requires visible local references, inspect each reference first.
• On success, call complete_agent_image_job with the real absolute local output path. On failure, call fail_agent_image_job. Never invent a path or submit an inline-only image that was not saved locally.
• Do not poll Esse. Each start, completion, and failure call updates the workbench directly.

12. When the user describes another change, resolve the target images before submitting work:

• If the current Esse MCP App context says the user selected images, treat phrases such as “我选择的图片” or “选中的图片” as those exact image IDs and local paths. Selection may contain a current result, a backup such as 图2-1, or the source image retained by a failed job.
• If the user explicitly names images such as 图1, 图2, or 图2-1, resolve those exact names from the current batch. Names embedded in a request sent by the Esse modification composer are already resolved; do not ask again.
• If no image is selected or named and the current batch has more than one available image, do not guess. Ask which image to modify and remind the user that they can type a name such as 图1, or double-click images in Esse to select them.
• If the batch has exactly one available image, an otherwise unambiguous modification request may target that sole image.
• Call modify_selected_images once with batchId and every exact resolved image ID in imageIds, whether each target is a current result, a backup, or a failed-job source. Never call create_image_batch for this workflow.
• A current successful result is updated in place and its previous version is kept as 图1-1, 图1-2, and so on. A selected backup or failed-job source creates a new job inside the same batch using that exact image; never substitute a different image. Pass offeringId only when the user explicitly names a model or selected it in the Esse widget; otherwise omit it so Esse reuses the batch model. Then follow the normal-Provider or agent-generation branch above.

13. When the user explicitly asks to delete images, resolve exact current-image or backup IDs and call delete_esse_images. Deleting a current image also deletes its preserved versions. Do not delete queued or running images, and do not treat deleting an image as permission to delete its whole batch.
14. When the user explicitly asks to combine distinct batches, call merge_image_batches with one exact targetBatchId and the exact sourceBatchIds. Do not use merge for append requests. Batches must be terminal and the merged target may contain at most 50 images. Preserve source batches by default; set deleteSourceBatches: true only when the user explicitly asks to remove them. Use a stable requestKey.

Guardrails

• Tell the user where selected files are sent: the chosen external Provider, or the current Agent's image-generation service/model for Codex 生成.
• Treat all price metadata as an estimate, not a bill or guaranteed charge. Do not volunteer or repeat price narration for routine generation. Mention a concise estimated amount only when the user asks about cost, compares models, or a higher-level policy explicitly requires confirmation.
• Never overwrite source images. Use the batch output directory returned by the tool.
• For normal Provider offerings, do not automatically retry a failed request whose chargeState is unknown. A direct click on Esse's retry button is already the user's explicit retry decision and must not trigger a second confirmation. Definitely-not-charged retryable failures may retry automatically up to three times.
• For Codex 生成, let the current Agent decide its own supported execution method, but always report a terminal success or failure to Esse.
• Preserve local paths exactly. Do not invent filenames or claim a folder was processed before the batch reaches a terminal status.
• Existing Esse images must be passed structurally through referenceImages; a matching phrase in the prompt does not count as attaching the image.
• Never infer one target from a multi-image batch when neither the user nor the Esse selection context identifies it. Treat current results, backups, and failed-job source images as distinct selectable images.
• Limit one batch creation, append, image-ID mutation, merge source list, and list_image_batches query to 50 items. Split larger work into deliberate operations with distinct request keys.
