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 | $0.00057 | $0.00502 |
| Opus 5 | $0.00028 | $0.00251 |
| Sonnet 5 | $0.00011 | $0.00100 |
| Haiku 4.5 | $0.00006 | $0.00050 |
Grade A, and why
1inch-orderbook 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 10d 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.
What it actually says
1inch Orderbook (limit orders)
Use the authenticated MCP tool orderbook. Required field: action — build | create | list | cancel.
Recommended: connect the user's wallet first (WalletConnect)
Unless the user wants to sign with their own tooling, offer WalletConnect before building: pair via the walletconnect tool (see the 1inch-walletconnect skill), then call orderbook with action: "build". With an active session, execute defaults to true — the tool signs the EIP-712 typed data and submits the order through the connected wallet in one step (including the one-time approve tx when needed); the user simply approves the prompts in their wallet app.
Set execute: false to get the typed data back for signing elsewhere.
Manual flow (no wallet session)
- build — server returns EIP-712
typedData,orderHash,orderData. Amounts in smallest units; assets as address or symbol. - sign —
eth_signTypedData_v4with the maker wallet. - create — submit
orderHash,signature,orderData. - list —
listMode:by_maker|by_hash|all. - cancel — loads on-chain cancel guidance (no HTTP cancel).
If build returns an approval block, broadcast approveTx first (native gas), then sign.

Example prompts
- "Build a limit order to sell 1 WETH for USDC on Ethereum"
- "List my open limit orders for 0x…"
What ships with it
1 file 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.

1inch-orderbook is a skill published in the GitHub repository 1inch/1inch-ai (2 stars, last pushed 13d ago), licensed MIT. It adds 57 tokens to every session and 502 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 2026-08-31.
