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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 29 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
What it costs to keep this loaded
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 | $0.00056 | $0.02519 |
| Opus 5.5 | $0.00022 | $0.01008 |
| Sonnet 5.5 | $0.00011 | $0.00504 |
| Haiku 4.5 | $0.00006 | $0.00252 |
Grade A, and why
nansen-limit-orders 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 23d 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 — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Authentication
Nansen account API calls accept a selected nansen:api browser session or conventional API key with the same permissions. NANSEN_API_KEY takes precedence; optional primaryEnv preserves configured-key injection. Run nansen auth status for offline selection. Cached access expiry alone permits automatic renewal during an authorized task. Stop on anonymous selection, invalid state, blocked/uncertain renewal or actual auth failure; never drop a credential or fall back to anonymous x402 payment. Browser login does not grant wallet signing, privileged service identity or a persistent MCP integration key. Preserve all confirmation, signing, sanctions and geographic checks below. Browser login is available in CLI 2.0.0 within the macOS arm64 preview scope.
Limit Orders
Use this skill when the user wants a price-triggered order. There are two distinct paths — pick the one that matches the user's chain:
- Solana → native limit orders.
nansen trade limit-order create|list|cancel|updateplaces real resting orders through the Nansen trading API. Use these for anything on Solana. - Other chains → alert-based approximation.
nansen-clidoes not yet place native limit orders on EVM chains. Place the resting order on the venue that supports it (CEX, DEX limit-order product) and create a companioncommon-token-transfersmart alert on the settlement wallet as a best-effort fill signal.
Prerequisites
- A Solana wallet configured in
nansen-cli:nansen wallet show <name>(ornansen wallet createif none exists). Local, Privy, and WalletConnect wallets are all supported fortrade limit-order. - The wallet must hold the sell token plus a small amount of SOL for fees.
- For the alert fallback: a notification channel (Telegram chat ID, Slack or Discord webhook, or generic webhook URL).
- A selected nansen:api browser session or conventional API key for smart alerts; existing endpoint restrictions still apply.

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.

nansen-limit-orders is a skill published in the GitHub repository nansen-ai/nansen-cli (139 stars, last pushed today), licensed MIT. It adds 56 tokens to every session and 2,519 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
