Asset Seeker — Online Creative Asset Search
Overview
Search free commercial-use creative assets across the internet from curated, high-quality sources. Covers photos, illustrations, icons, video footage, music, sound effects, and fonts — all vetted for license safety (CC0 / free commercial use).
Backed by the research from the "创作者素材库大盘点" video — every source has been verified for license terms, China accessibility, and API availability.
When to Use This Skill
Activate when the user needs to find online assets for content creation:
- "Find me a photo of mountains for a video thumbnail"
- "Search for laptop icons in outline style"
- "I need drone footage of city traffic for B-roll"
- "Find calm piano background music"
- "Search for a bold Chinese font for my title"
- "找一张科技感的图片" / "帮我搜个图标" / "有没有免费商用的视频素材"
Do NOT use for: local file search, video editing, or asset management tools (Eagle/Billfish).

Workflow
Step 1 — Understand the request
Determine:
- Asset type: photo / icon / video / music / sfx / font / illustration
- Keywords: what the user is searching for
- Style hints: orientation, color, mood, style
If the type is ambiguous, ask briefly. Otherwise proceed.
Step 2 — Check API keys
Run the prerequisite check:
SKILL_DIR="${SKILL_DIR:-${CLAUDE_SKILL_DIR}}"
python3 "${SKILL_DIR}/scripts/seek_assets.py" sources
This lists all available sources and whether their API keys are configured. Without any API key, only Iconify (icons) will work — tell the user and suggest setting up at least PEXELS_API_KEY (free, most versatile).
Step 3 — Search
python3 "${SKILL_DIR}/scripts/seek_assets.py" search photo "mountain sunset"
python3 "${SKILL_DIR}/scripts/seek_assets.py" search icon "laptop"
python3 "${SKILL_DIR}/scripts/seek_assets.py" search video "city traffic"
python3 "${SKILL_DIR}/scripts/seek_assets.py" search video "sunset" --source mixkit
python3 "${SKILL_DIR}/scripts/seek_assets.py" search sfx "whoosh"
python3 "${SKILL_DIR}/scripts/seek_assets.py" search font "bold sans-serif"
python3 "${SKILL_DIR}/scripts/seek_assets.py" search photo "cat" --max 10
python3 "${SKILL_DIR}/scripts/seek_assets.py" search photo "landscape" --orientation landscape
python3 "${SKILL_DIR}/scripts/seek_assets.py" search icon "arrow" --format text
Step 4 — Present results
For each result, show:
- Thumbnail/preview URL (when available)
- Source name + license
- Download link or instructions
- Any attribution requirements
For Iconify, also show the icon set name and suggest usage (e.g., <span class="iconify" data-icon="mdi:laptop">).
Step 5 — Download (if needed)
python3 "${SKILL_DIR}/scripts/seek_assets.py" download <url> --output poster_bg.jpg
For sources without direct API download, open the page URL in browser or instruct the user to download manually.
Commands

Environment Variables
