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 | $0.00054 | $0.01306 |
| Opus 5 | $0.00027 | $0.00653 |
| Sonnet 5 | $0.00011 | $0.00261 |
| Haiku 4.5 | $0.00005 | $0.00131 |
Grade A, and why
yield-vault-guide 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 2d 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 — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Yield Vault Guide
Yield vaults automate DeFi strategies, auto-compounding rewards so you don't have to manually claim and reinvest.
How Vaults Work
1. You deposit tokens into a vault
2. Vault executes a strategy (e.g., farm + auto-compound)
3. Rewards are claimed and reinvested automatically
4. Your share of the vault grows over time
5. Withdraw anytime — receive original token + accumulated yield
Vault vs Manual Farming
| Factor | Vault | Manual |
|---|---|---|
| Compounding | Automatic | You claim + reinvest |
| Gas costs | Shared across users | You pay each time |
| Optimization | Professional strategies | You manage |
| Effort | Set and forget | Daily/weekly maintenance |
| Fees | Vault fees (2–10%) | No protocol fees |
Major Vault Protocols
Yearn V3
The original yield aggregator. Multi-strategy vaults that allocate across opportunities.
| Feature | Detail |
|---|---|
| Chains | Ethereum, Arbitrum, Base, Polygon, Optimism |
| Strategies | Multi-strategy per vault |
| Fees | 10% performance fee |
| Audit | Multiple audits, 3+ years live |
How Yearn works:
- Deposit USDC into the USDC vault
- Yearn allocates across 3–5 strategies (lending, LP, farming)
- Strategies auto-compound
- Withdraw with accumulated yield
Beefy Finance
Cross-chain auto-compounder. Widest protocol coverage.
| Feature | Detail |
|---|---|
| Chains | 20+ chains |
| Strategies | Single-strategy per vault (focused) |
| Fees | 4.5% performance fee + 0–0.1% deposit |
| Audit | Multiple audits, 2+ years live |
Beefy's approach:
- Each vault targets one specific farm
- Claims rewards → swaps to underlying → re-deposits
- Simple and transparent
Convex / Aura
Specialized for Curve and Balancer pools:
- Convex: Boost Curve LP rewards (CRV + CVX)
- Aura: Boost Balancer LP rewards (BAL + AURA)
Evaluating Vaults
Key Metrics
| Metric | What to Check | Good Sign |
|---|---|---|
| TVL | Total deposited | >$1M for established vaults |
| APY (net) | After fees | Competitive vs alternatives |
| Strategy | What it does | Understandable, tested strategy |
| Audit | Security reviews | Multiple audits, no past incidents |
| Age | Time in production | >6 months preferred |
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.

yield-vault-guide is a skill published in the GitHub repository nirholas/three.ws (110 stars, last pushed today), licensed Apache-2.0. It adds 54 tokens to every session and 1,306 once invoked, about $0.0003 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 2026-09-03.
