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 low
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 →
- low Privilege Escalation · line 68 Skill requests more permissions than appear necessary for its stated functionality. Review if elevated access is justified.Fix: Request only the minimum permissions required. Document why each permission is needed. Remove broad permissions like '*' or 'all'.
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 | $0.00105 | $0.02390 |
| Opus 5.5 | $0.00042 | $0.00956 |
| Sonnet 5.5 | $0.00021 | $0.00478 |
| Haiku 4.5 | $0.00011 | $0.00239 |
Grade A, and why
p2p 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 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.
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.

Binance P2P Trading Skill
Help users interact with Binance P2P (C2C) via natural-language queries.
When to Use / When NOT to Use
Use this skill when the user wants to:
- Check P2P buy/sell quotes for a crypto/fiat pair (e.g., USDT/CNY).
- Search P2P advertisements and filter by payment method(s), limits, merchant quality.
- Compare prices across payment methods (e.g., Alipay vs bank transfer).
- View their own P2P order history / summary (requires API key).
Do NOT use this skill when the user asks about:
- Spot/Convert prices, futures/derivatives, margin, trading bots.
- Deposits/withdrawals, wallet transfers, on-chain transactions.
- Creating/cancelling orders, appeals, releasing coins (trading operations).
Ask clarifying questions (do not guess) if any key inputs are missing:
fiat(e.g., CNY)asset(e.g., USDT)- user intent: buy crypto or sell crypto
- preferred payment method(s)
- target amount (optional but recommended for ad filtering)
Core Concepts
tradeType mapping (avoid ambiguity)
- User wants to buy crypto (pay fiat, receive USDT/BTC) →
tradeType=BUY - User wants to sell crypto (receive fiat, pay USDT/BTC) →
tradeType=SELL
Always reflect this mapping in responses when the user’s wording is ambiguous.
Capabilities
Phase 1 — Public Market (No Auth)
- Quote P2P prices
- Search ads
- Compare payment methods
- Filter/Rank ads by limits and merchant indicators
Phase 2 — Personal Orders (Requires API Key)
- List P2P order history

- Provide summary statistics
Security & Privacy Rules
Credentials

BINANCE_API_KEY(sent as header)BINANCE_SECRET_KEY(used for signing)
Never display full secrets
- API Key: show first 5 + last 4 characters:
abc12...z789 - Secret Key: always mask; show only last 5:
***...c123
Permission minimization
- Binance API permissions: Enable Reading only.
- Do NOT request/encourage trading, withdrawal, or modification permissions.
What ships with it
3 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.
