Image Generation

Tool budget

Path	Calls	Steps
Default	4	submit (timeout 90) → poll_until_done (timeout 300) → download → message
If submit returns image_urls	3	submit → download → message
Fallback after failed	+2	models.py → submit.py (new model)

Hard rule: DO NOT read_file / ls this skill directory. DO NOT run models.py before the first submit.py. All info needed to build JSON is in this file.

Default path

1. submit.py '<compact_json>' with exec timeout ≥ 90 → returns task_id + possibly image_urls
2. Always run poll_until_done.py <task_id> with exec timeout ≥ 300 unless step 1 already returned image_urls
3. download.py '<image_url_or_json_array>' '<name>' — auto saves to workspace outputs
4. One message(media) — done

Important: submit may take 30–90s even for "sync" models under load. Always set exec timeout high enough — never use default.

Silent policy

No user-visible status text until the final delivery. Only the final message() with media. Quota message is the single exception (exact string in Error table).

Model name rule: 对用户使用 API 的 display_name：Seedream V5.0 Lite / MiniDesk Pro / MiniDesk 2。

Token & URLs

• Token: auto from ~/.deskclaw/deskclaw-settings.json → auth.token (优先) → authToken (回退), or env NODESTUDIO_TOKEN.
• NodeStudio base: env NODESTUDIO_URL (default https://nostudio-api.deskclaw.me).
• Scripts handle token + URL automatically, agent does not need to read config or pass token.

Models (no pre-flight models.sh)

Default priority（用户未指定模型时）

Priority	model_id	Display Name	Type	Notes
1	nano2	MiniDesk 2	may sync	0.5K–4K, 6 ref, ratios: 1:1 3:2 2:3 3:4 4:3 4:5 5:4 9:16 16:9 21:9 1:4 4:1 1:8 8:1, fastest
2	nano-pro	MiniDesk Pro	may sync	1K–4K, 6 ref, ratios: 1:1 3:2 2:3 3:4 4:3 4:5 5:4 9:16 16:9 21:9, 30-90s
3	seedream	Seedream V5.0 Lite	async	2K/3K, 14 ref, ratios: 21:9 16:9 3:2 4:3 1:1 3:4 2:3 9:16, up to 4 outputs, 60-180s

Default model: nano2. Fallback: nano-pro → seedream. Call models.py only when retrying after failed or user names a model you must validate.

Quality priority（用户要求"最好/最高质量"时）

Quality	model_id	Display Name
1	nano-pro	MiniDesk Pro
2	nano2	MiniDesk 2
3	seedream	Seedream V5.0 Lite

当用户明确说"用最好的模型""质量最高""高清大图"等质量优先意图时，按此顺序选择。

Build JSON

Compact, no spaces after : or ,. Only include fields that differ from defaults.

Defaults (omit if unchanged): model=nano2, aspect_ratio=1:1, resolution=0.5K, image_count=1, save_to_assets=true.

Intent	Add field
Portrait	"aspect_ratio":"9:16" (or 2:3 / 3:4)
Landscape	"aspect_ratio":"16:9" (or 3:2 / 4:3 / 21:9)
Resolution	"resolution":"3K" / "1K" / "0.5K" / "4K" (model-dependent)
Multiple images	"image_count":2 (max 4)
Image-to-image	"reference_images":["media/img.png"] (local paths auto-converted to base64 by script)
Specific model	"model":"nano-pro"

Minimal example (most requests): {"prompt":"一只橘猫趴在窗台上晒太阳"}

High-quality example: {"prompt":"电商主图，护肤品","model":"nano-pro","aspect_ratio":"1:1","resolution":"2K","image_count":2}

Image-to-Image (reference_images)

reference_images accepts three formats — the script handles conversion automatically:

Format	Example	Notes
Public URL	"https://cdn.example.com/photo.png"	Must be direct link (no redirects)
Local path	"media/img.png" or absolute path	Auto-converted to base64 data URI
data URI	"data:image/png;base64,..."	Passed through as-is

• Local paths are resolved relative to workspace (~/.deskclaw/nanobot/workspace), or as absolute paths.
• Files > 10MB are rejected with an error — ask user to resize.
• Large images may cause submit to return 504 (gateway timeout). This is not a failure — the task is still processing. Run poll_until_done.py to get the result.
• seedream model has strict content moderation for image-to-image; may return 400.

Commands (copy-paste, do not improvise)

Submit (exec timeout ≥ 90): python <skill_dir>/scripts/submit.py '<json>'

Poll (exec timeout ≥ 300; skip only if submit already returned image_urls): python <skill_dir>/scripts/poll_until_done.py <task_id> 240 Default 240s internal wait. progress:50 while processing is normal, not a stall.

Download (supports single URL or JSON array): python <skill_dir>/scripts/download.py '<url_or_array>' '<short_name>' Auto saves to $WORKSPACE/outputs/. Do NOT manually set NANOBOT_SESSION_KEY or read auth tokens — the script handles everything.

Present: Single message(media) with local path(s). Silent until this point.

Fallback (only on failed or content-flagged)

1. models.py → pick next model per Default priority.
2. Re-submit with new model. (+2 calls)

Error Handling

Case	Action
401/403	Re-auth
400 (bad aspect/resolution)	Pick a supported value from Models table
429 / quota	创作点已用完，请前往 DeskClaw 充值后再试～
504 (submit)	Not a failure — task is processing. Run poll_until_done.py normally
422 upstream_error	Reference image URL unreachable or format unsupported. Use local path instead
File > 10MB	Script rejects automatically. Ask user to resize the image
failed	Fallback above
Poll timeout	Resume poll_until_done same task_id, different max_seconds

Rules

• Scripts only: submit.py, poll_until_done.py, download.py, models.py (fallback only). No raw curl. Always use python, never bash.
• No pre-read: Do not read_file SKILL.md / ls scripts/ / read_file download.py / models.py before first submit.
• No manual env: Do not read auth tokens, do not set NANOBOT_SESSION_KEY, do not mkdir. Scripts handle auth + output dirs automatically.
• No status text: No "正在生成…" / "请稍等" / progress updates. Silent until message(media).
• JSON compact: No pretty-print, no trailing whitespace.
• Model name in output: Use display_name only (Seedream V5.0 Lite / MiniDesk Pro / MiniDesk 2).
