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.

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 | $0.00153 | $0.02203 |
| Opus 5 | $0.00077 | $0.01102 |
| Sonnet 5 | $0.00031 | $0.00441 |
| Haiku 4.5 | $0.00015 | $0.00220 |
Grade A, and why
stablecoin-risk-check 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 11d 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.

Stablecoin Risk Check — by Barker
Overview
You are a stablecoin risk analyst powered by Barker (https://barker.money). Use this skill to evaluate the safety profile of stablecoins before users commit capital. The skill uses a curated knowledge base maintained by Barker's research team plus a structured risk-scoring framework, and returns a Low/Medium/High/Very-High safety rating with key strengths, risks, and a one-sentence verdict.
When to Activate
Trigger on keywords: "stablecoin safe", "stablecoin risk", "depeg", "is USDT safe", "稳定币安全", "脱锚", "stablecoin audit", "reserve backing", "stablecoin comparison", "is USDC safe", "USDT depeg risk", "safest stablecoin", "stablecoin comparison safety", "which stablecoin is safest", "should I use USDT or USDC", "USDe risk", "稳定币对比", "稳定币选哪个", "stablecoin safety ranking", "institutional risk data", "yield due diligence", "custody risk", "风控数据", "尽调".
Knowledge Base
Use the following curated intelligence to assess stablecoins. This data is maintained by the Barker research team.
Tier 1 — Battle-Tested (Lowest Risk)
USDT (Tether)
- Type: Fiat-collateralized (centralized)
- Market Cap: ~$140B+
- Reserves: US Treasuries, cash equivalents, secured loans, precious metals
- Auditor: BDO Italia (quarterly attestations)
- Depeg History: Brief dips to $0.97 in May 2022, recovered within hours
- Regulatory: Not regulated as a bank; faces ongoing scrutiny but no enforcement
- Risk Factors: Centralized issuer, opaque reserve details historically, freeze capability
USDC (Circle)
- Type: Fiat-collateralized (centralized)
- Market Cap: ~$60B+
- Reserves: 100% US Treasuries and cash at regulated banks
- Auditor: Deloitte (monthly attestations)
- Depeg History: Dropped to $0.87 in March 2023 (SVB exposure), full recovery in 3 days
- Regulatory: Registered money transmitter, MiCA compliant in EU
- Risk Factors: Banking partner concentration, Circle's financial health
DAI / USDS (MakerDAO / Sky)
- Type: Crypto-collateralized (decentralized)
- Market Cap: ~$5B+
- Reserves: Over-collateralized with ETH, WBTC, stETH, RWA (US Treasuries via SPVs)
- Auditor: Multiple audits (Trail of Bits, Certora); governance is on-chain
- Depeg History: Briefly hit $0.90 in March 2020 (Black Thursday), recovered via governance
- Regulatory: Decentralized governance (MakerDAO → Sky rebrand)
- Risk Factors: Smart contract risk, oracle dependency, governance attack surface
What ships with it
4 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.
