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 | $0.00112 | $0.01266 |
| Opus 5 | $0.00056 | $0.00633 |
| Sonnet 5 | $0.00022 | $0.00253 |
| Haiku 4.5 | $0.00011 | $0.00127 |
Grade A, and why
yield-xyz-agentkit-robinhood 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 6d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **Never call the Yield.xyz API directly** (curl/HTTP) — it requires an API key How it starts
The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Yield.xyz AgentKit × Robinhood Chain
The Robinhood Chain connector for the Yield.xyz AgentKit: it adds the Robinhood Chain (mainnet) configuration the rest of the kit needs, and points your existing EVM signer at the chain. Robinhood Chain is an Arbitrum Orbit L2 (chain ID 4663) with ETH as its gas token.
yield-xyz-agentkit (this skill's base) owns all yield logic — discovery, schemas, validator selection, balances, building unsignedTransaction (actions_enter / actions_exit / actions_manage), output formatting, and the MCP tool reference. Use it for all of that; this skill only adds Robinhood Chain configuration and funding guidance.
Robinhood Chain is an EVM network, so signing and broadcasting are identical to any other EVM chain — this skill does not hold keys, sign, or broadcast. Bring your own EVM signer (a user's wallet, your agent's custody, or a connector like Privy).
Robinhood Chain → configure chain (RPC + chainId) + fund wallet (bridge ETH + deposit token)
yield-xyz-agentkit → discover yield + build unsignedTransaction
Your EVM signer → sign + broadcast (same as any EVM chain)
yield-xyz-agentkit → submit_hash + poll get_transaction
CRITICAL
- Never modify
unsignedTransactionbefore signing — not addresses, amounts, fees, or encoding. If anything looks wrong, haveyield-xyz-agentkitbuild a NEW action. Modifying it will result in permanent loss of funds. - Never call the Yield.xyz API directly (curl/HTTP) — it requires an API key
and returns
401. All Yield.xyz access goes through the MCP (handled by theyield-xyz-agentkitskill). - Mainnet. Robinhood Chain here is mainnet (chain ID
4663); gas is paid in ETH. Match yields and balances by the deposit token's contract address, not by symbol. Seereferences/chain-config.md.
Prerequisites
- Yield.xyz AgentKit MCP connected (owned by the
yield-xyz-agentkitskill). - An EVM signer able to sign and broadcast on Robinhood Chain mainnet.
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.

yield-xyz-agentkit-robinhood is a skill published in the GitHub repository stakekit/agentkit (3 stars, last pushed 1mo ago), licensed MIT. It adds 112 tokens to every session and 1,266 once invoked, about $0.0006 per session on Opus 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 2026-08-31.

contract-decode
EVM contract error and calldata decoder. Use when: user pastes hex revert data, calldata, function selector, or mentions custom error, execution reverted, 4byte, decode. Input contains 0x + 8+ hex chars.
invest
First-time fork users: run the invest-setup skill first to initialize. The main flow lives in this skill (the AI agent uses the CLI/MCP to view the portfolio / run the committee / replay decision history). The Web GUI has been retired (2026-07) — every capability is exposed via CLI subcommands / MCP tools. The backend…
invest-setup
First-time openInvest installation and onboarding. ONLY use when user explicitly says "set up invest" / "init invest" / "帮我初始化 invest", OR when invest skill's doctor returns status="needssetup". NOT for daily usage — once onboarding is done, the invest skill takes over (portfolio viewing, committee analysis, buy/sell…

Back up / restore openInvest's local state — memory/ (holdings, strategy, user profile, committee records, dream logs) + db/ (trade ledger, job run history, market-data cache) + .env (SMTP/API credentials) + userprofile.json. All of this data is .gitignore'd with no historical versions in git, so a single accidental…
