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 medium
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 →
- medium Data Exfiltration · line 185 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00025 | $0.07383 |
| Opus 5.5 | $0.00010 | $0.02953 |
| Sonnet 5.5 | $0.00005 | $0.01477 |
| Haiku 4.5 | $0.00003 | $0.00738 |
Grade A, and why
legal-downloading scanned grade A with 1 finding 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 1mo 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.

Legal Downloading
Download media legally and responsibly. This skill covers the legal landscape of media downloading — what's allowed, what's not, and how to build workflows that respect copyright while still getting the content you need offline.
Core Principles
1. Copyright Is Not Optional
Copyright law protects creators' rights to control reproduction and distribution of their work. Downloading copyrighted content without permission is infringement in most jurisdictions, regardless of whether you're "just sharing" or "only for personal use."
2. Permission Comes in Many Forms
Not all downloading requires explicit permission. Look for:
- Explicit permission: Creative Commons, public domain, or direct creator authorization
- Implied permission: Platform download features, offline modes, RSS feeds
- Statutory permission: Fair use/fair dealing, time-shifting, format-shifting (jurisdiction-dependent)
3. Platform Terms Matter
Each platform has its own terms of service that govern what you can do with content. YouTube's Terms of Service prohibit downloading videos unless a download button or API is provided. Violating ToS isn't necessarily illegal, but it can get your account terminated.
4. Know Your Jurisdiction
Copyright law varies significantly by country. Fair use (US) is broader than fair dealing (UK, Canada, Australia). Private copying exceptions exist in some EU countries but not others. Know the laws that apply to you.
Understanding Copyright and Fair Use
What Copyright Protects
Copyright protects original works of authorship fixed in a tangible medium:
- Audiovisual works: Movies, TV shows, videos
- Sound recordings: Music, podcasts, audio books
- Literary works: Books, articles, code
- Musical works: Compositions, lyrics
Copyright grants the creator exclusive rights to:
- Reproduce the work
- Create derivative works
- Distribute copies
- Perform the work publicly
- Display the work publicly
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.

legal-downloading is a skill published in the GitHub repository cosmicstack-labs/mercury-agent-skills (487 stars, last pushed 2mo ago), licensed MIT. It adds 25 tokens to every session and 7,383 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
