Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

System instructions should never be exposed to end users.
What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00152 | $0.01913 |
| Opus 5 | $0.00076 | $0.00957 |
| Sonnet 5 | $0.00030 | $0.00383 |
| Haiku 4.5 | $0.00015 | $0.00191 |
Grade A, and why
linkfox-echotik-get-video-download-url scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
EchoTik TikTok Video Download
This skill guides you on how to resolve a TikTok video URL into direct download and playback links, helping sellers save influencer/promotional video assets for offline analysis or reuse.
Core Concepts
This tool takes a single TikTok video URL and resolves it to direct media addresses: a no-watermark download URL (preferred for clean assets), a watermarked download URL, a playback URL, and cover images (static and dynamic). This is useful when a seller wants to archive a high-performing promotional video found via the EchoTik product-video tool, or reuse a creator's clip without re-recording.
Required input: A url is mandatory. Two URL formats are accepted:
- Short link:
https://vt.tiktok.com/xxxxxx - Full link:
https://www.tiktok.com/@user/video/1234567890
Conditional download URLs: Not every video returns a downloadable address. noWatermarkDownloadUrl and downloadUrl are returned only when the source video allows it; for some videos (region/privacy/availability restricted) both are absent and only playUrl plus cover images come back. Always check presence before presenting a download link, and fall back to playUrl for playback when the download fields are missing.
URL freshness: The returned download/playback addresses may expire over time. Use them promptly after resolving, and re-resolve if a link stops working.
Parameter Guide
| Parameter | Type | Required | Description | Default |
|---|---|---|---|---|
| url | string | Yes | TikTok video URL (short link vt.tiktok.com/xxx or full link tiktok.com/@user/video/xxx). Max length 1000 |

调用方式
- API 端点：
POST /echotik/getVideoDownloadUrl（完整参数/响应/错误码见references/api.md） - Python 脚本：
python scripts/echotik_get_video_download_url.py '<JSON 参数>' [--inline] - 成本约束：本工具会消耗积分；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。
输出策略（脚本默认行为）：
- 始终将完整响应写入
<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-echotik-get-video-download-url-<timestamp>.json（<cwd>为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；<session>取自环境变量SESSION_ID，按用户任务自动聚合；禁止写入 /tmp，当前目录不可写则报错） - 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout
- 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如
total/costToken、最大列表字段的长度 + 前 3 条样本） - 加
--inline强制全量打印到 stdout（同样落盘）
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

linkfox-echotik-get-video-download-url is a skill published in the GitHub repository linkfox-ai/linkfox-skills (101 stars, last pushed 22d ago), licensed MIT. It adds 152 tokens to every session and 1,913 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
