Run quality checks on a task's implementation before it closes to done. Triggers: 'is this ready?', 'run the review gate', 'check my work', 'I think this is done'. Reviews code + spec adherence, runs tests/build. Design review uses taskmaster:spec-review.
Log a lightweight idea into .taskmaster/ideas/. Triggers: '/add-idea', 'save this as an idea', 'remember this idea', 'log this idea', or something worth keeping, not yet a task. Only way - not backlog_idea_create directly.
Log/update/close project bugs in .taskmaster/bugs/. Triggers: 'log a bug', 'this is a bug', 'track this defect', 'I found a bug', 'shelve this for later', 'list open bugs', 'promote B-XX', 'close B-XX'. Also for ambiguous 'issue' phrasing lacking recurring/systemic/outstanding evidence - falls back here. Only correct way to transition a project Bug.
Scan the codebase for TODO/FIXME/HACK/XXX and cross-reference the backlog. Triggers: 'check todos', 'are my todos tracked', 'scan for todos', 'todo audit', 'what's untracked'.
Write/resolve/drop project decisions in .taskmaster/decisions/. Invoke when about to write an inline option menu - route here, not Options: in chat. Also 'choose between', 'pick an option', 'decide on', 'open question', 'resolve DEC-X', 'drop DEC-X'. Only correct way - do not call backlog_decision_create directly.
Close out a work session. Triggers: 'end session', 'I'm done for today', 'let's wrap up', 'mark this task done', 'save progress'. ONLY correct way to mark tasks done/in-review with a session record.

| description | Generate, edit, or refine images using Gemini or OpenAI. Auto-detects intent from context. |
You have access to image generation via a Node.js script. Supports two backends: Gemini (default) and OpenAI (GPT Image 2, with GPT Image 1.5 retained for transparency).
Analyze the user's request and route:
| Signal | Action |
|---|---|
| No existing image referenced | Generate — invoke image-gen:generate |
| User references an existing image file path | Edit — invoke image-gen:edit |
| User says "refine", "iterate", "adjust", or references a previously generated image from this session | Refine — invoke image-gen:refine |
| Need | Backend | Why |
|---|---|---|
| General image generation | gemini (default) | Fast, free tier, good quality |
| Transparent backgrounds (game assets, sprites, icons) | openai with --transparent | Auto-uses gpt-image-1.5 (native alpha). gpt-image-2 does not support transparency — script falls back automatically. |
| Transparent + Gemini style | gemini with --transparent | Two-pass alpha extraction (slower, 2 API calls) |
| Highest quality generation | openai with --quality high | gpt-image-2 is the new state-of-the-art default |

Defaults: backend=gemini, model=auto (gemini-3.1-flash-image-preview or gpt-image-2), aspect=1:1, size=1K, quality=medium
Gemini models:
gemini-3.1-flash-image-preview — Fast, good for iteration (default)gemini-3-pro-image-preview — Highest quality, use for final/polished assetsgemini-2.5-flash-image — High-volume, low-latencyOpenAI models:
gpt-image-2 — State-of-the-art, fastest, supports flexible sizes up to 3840px and quality=auto (default).gpt-image-1.5 — Retained for transparent backgrounds. gpt-image-2 does not support background=transparent, so the script auto-falls-back to gpt-image-1.5 whenever --transparent is set. You can also pin it explicitly with --model gpt-image-1.5.Aspect ratios: 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9
Gemini sizes: 512px, 1K, 2K, 4K OpenAI sizes: Mapped from aspect ratio (1024x1024, 1536x1024, 1024x1536)
OpenAI quality (1024x1024):
gpt-image-2: low ~$0.005, medium ~$0.041, high ~$0.211, auto (default for the model)gpt-image-1.5: low $0.009, medium $0.034, high $0.133After routing, invoke the appropriate sub-skill. Do NOT generate images directly from this router — always delegate to a sub-skill.
