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 | $0.00046 | $0.06280 |
| Opus 5.5 | $0.00018 | $0.02512 |
| Sonnet 5.5 | $0.00009 | $0.01256 |
| Haiku 4.5 | $0.00005 | $0.00628 |
Grade A, and why
yield-xyz-agentkit 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.

Yield.xyz AgentKit
A skill for discovering and acting on DeFi yield opportunities via the Yield.xyz MCP server.
Integration Boundary
This skill is the yield layer — it discovers yields, inspects their schemas, and builds unsigned transactions. It never holds keys, signs, or broadcasts, and it's tied to no wallet or custody product. Drop it into any agent or app that can already sign, and it becomes that agent's expertise for earning yield.
Responsibility splits cleanly on every transaction:
- This skill builds the
unsignedTransaction(actions_enter/actions_exit/actions_manage). - Your side signs and broadcasts it. Whatever does that is your signer — a user's wallet, your agent's own custody (MPC / KMS / HSM), or a provider like Privy or MoonPay. This skill doesn't care which.
- This skill records the result —
submit_hashwith the returned hash, thenget_transactionuntilCONFIRMED. Assume step 3 is yours. Drop it only where your host has explicitly told you that it signs, broadcasts and registers the hash in one step.
This holds whether signing is human-approved or fully autonomous. Where a human is in the loop, confirm before signing; where the host signs on its own, skip the confirmation and let it run.
How to Call Tools — Read This First
Always call tools via the connected MCP server (https://mcp.yield.xyz/mcp). Never fall back to curl, bash, or raw HTTP requests.
The MCP server exposes these tools directly — call them like any other tool:
- yields_get_all — list/filter yields
- yields_get — get one yield by ID
- yields_get_validators — list validators for a yield
- yields_get_balances — check wallet balances
- yields_get_reward_rate_history — historical APY/reward rate data for a yield
- yields_get_tvl_history — historical TVL data for a yield
- yields_get_risk — detailed risk parameters for a yield
- yields_get_kyc_status — check a wallet's KYC/eligibility status for a permissioned (RWA) yield
- actions_enter — enter a position
- actions_exit — exit a position
- actions_manage — claim rewards / manage position
- actions_get — get status of a specific action
- actions_get_all — list action history for a wallet
- submit_hash — submit on-chain tx hash after signing and broadcasting (mandatory, unless your host has explicitly said it registers the hash itself)
- get_transaction — poll transaction confirmation status
- networks_get_all — list all supported networks
- providers_get_all — list all supported protocols and providers
What ships with it
8 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 is a skill published in the GitHub repository stakekit/agentkit (4 stars, last pushed 23d ago), licensed MIT. It adds 46 tokens to every session and 6,280 once invoked, about $0.0002 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 2026-08-31.

invest-setup
A first-time setup workflow for openInvest, a system for tracking investments and running portfolio analysis.
invest-backup
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…

BETA — not recommended for anyone. Operator notes for openInvest's experimental IBKR live autopilot: an LLM picks and trades US stocks / ETFs in a real Interactive Brokers cash account through a local IB Gateway, with no human confirmation per trade. Use ONLY when the user explicitly operates an IBKR INVESTHOME that…

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…

Portfolio system knowledge base. Use when: position queries, routing strategy questions, provider integration. Not for: general code exploration (use code-explore), code review (use codex-code-review). Output: domain-specific analysis + recommendations.
